  2. On my seemingly-eternal search for interesting lenses for close-up work I could not help but come across the Schneider Kreuznach Macro Varon 85mm f/4.5 CAS lens, if only because Schneider promotes the Macro Varon all over the place. And that’s a lot of promotion for a lens most photographers have never heard of. Well, I heard about the Macro Varon and searched it down to its price tag of $4500 and that set me back on my heels a bit. I don’t need a new lens THAT much. Well, perhaps a Zeiss Otus or two would be alright. I did make some calls, sent out some email requests and finally found that the Macro Varon could be had for somewhere in the mid $3K range brand-new. Well, of course that just sent me to Ebay looking for used copies. However, while it has happened, the Macro Varon does not show up used on Ebay very often, in fact hardly ever. Well, that limited my searching. I did find out that one sold on Ebay some time ago. Again, I spoke with Schneider reps about the Makro Varon on the phone and finally just let it go. It’s not that I don’t have other lenses that I might buy. LOL. And for those of you foolish so think I’m rich, guess again. I sell old equipment to buy new equipment as I go along. I just do it methodically. To make a long story short, recently a good friend sent me a message that there was a Makro Varon actually on Ebay for $1500. Well, that turned the corner for me and I bought it in about 15 seconds from receiving the message. It came from China, was used, but looked in decent condition. When the lens finally showed up at my door it was obviously brand new or in mint condition. However, it came in a strange industrial lens-mount which held the lens captive with three very tiny screws. I exhausted my collection of tiny screwdrivers, flat, Phillips, and torx (star). Then I called the local optician and gear-heads and no one had a tool that small. Well, that was disappointing, since I had no way to mount the lens without removing this big clucky adapter that gripped it first. Then I went salvaging through dozens of boxes of camera-related stuff and finally found a set of tiny torx drivers, but none of them was small enough to work. But, there was one (tiny) hole where a missing torx wrench should be. Where was it? And sure enough, in the bottom of my box of Cambo Actus parts was the tiny torx screwdriver and to my surprise, it worked! I had the lens mounted in a few minutes and was good to go. Now, I wanted to find out if this lens is best mounted directly to the camera and the camera placed on a focus rail, or should the lens be mounted directly on the camera with a small helicoid to focus with. The lens itself has no way to focus. It has six aperture blades (I wish there were more) and It has f/stops from f.4.5 through and including f/8. It does have something special, however. The Macro Varon has an additional ring on the barrel that allows me to adjust the floating lens parts in the lens to fit a particular magnification ratio 0.5x to 2.0x. This compensates and suppresses aberration depending on the magnification ratio. The only other lens that I have that has such a ring is the first edition of the Nikon Printing Nikkor 150mm APO f/2.8. These rings actually work. Another rather unique feature of the Macro Varon is that on each individual lens, during final adjustment, a tiny drop of red paint is placed on the rim of the barrel that allows (when the M42 adapter is screwed on tight) us to orient the particular lens to the camera sensor orthogonally, at right-angles. This is red dot calculated and optimized for each individual lens. Anyway, I soon figured out that (at least for now) I get the most play out of mounting the lens on the Cambo Actus Mini View Camera. Next, I had to decide what kind of hood would be best, since my first shots (made without a hood) lacked a bit of contrast. I tried both flared and narrow-tube hoods and finally fashioned one from the Nikon K-Ring set, one K5 plus two K3s all screwed together. They made a nice tubular hood that seems fine so far. Mounted on the Cambo Actus Mini, I soon found out that rather than the large (special order) cambo bellows I normally use that prevented me from getting as much field of view as I wanted with this lens, so I substituted a short bellows, which is fine because I do not need as much room with the Macro Varon anyway. That helped a bunch. I could also look into using a tiny extension/helicoid mounted directly on the camera, but I doubt that I would gain much, and moving the rear-standard on a view camera is better for stacking than using a helicoid. Anyway, I am up and running. Here is a quick photo of my setup, the Nikon D850 on the Cambo Actus Mini. On that is the Schneider Macro Varon 85mm f/4.5 lens adapted to Nikon mount, with a hood made of several K-rings. So far, so good. And I include a couple of early shots taken with the Makro Varon to give you an idea of what this lens can produce. This setup is not hiking-material, but certainly can go outside to the fields and meadows, at least if there is easy access so that the gear does not have to be carried far. The lens itself would be easy to carry for hikes, but would have to include some form of helicoid to focus or be happy with a DOF at F/8 and fixed focus. Anyway, I’m checking out the Schneider Macro Varon 85mm and would be interested in any other user’s experience.

  3. I have been stacking focus for many years now, so I’m no stranger to this technique. And the track of my learning curve (more like a spiral) has been fueled by my using better and better corrected lenses (APO) to enhance the stacking. In other words, the more finely corrected the lenses, the more careful I have to be in stacking, and on around. It’s like a Catch-22. I get lots of emails and messages about my photos. And not infrequently (at least from photographers) is the question as to whether I have tried one of the automated focus rails. In the past, I have taken a certain amount of pride in pointing out to these folks that I can stack quite well manually, thank you very much. I had no intention of varying my technique. Yet, as I pointed out above, the circular spiral of finer lenses and precise stacking led to more and better apochromatic lenses, like the Zeiss Otus series, the APO-El Nikkor 105, the Leica Elmarit-R APO 100mm macro, and so on. I pretty-much took these fine lenses in stride, hopefully learning to use them more and more skillfully. Then comes the Schneider Macro Varon 85mm industrial lens. I had kind of heard about this lens on and off for some time, but never had seen one come up used on Ebay and even trying to get availability and a firm price from the manufacturer and distributors was difficult. It was almost as if they did not want to sell to me because I was not a company that required industrial lens for line-scanning. I wrote them. I called them on the phone. A more detailed story about the Macro Varon would require a separate article. Suffice it to say that a good friend of mine, another photographer, sent me a FB message telling me that a Macro Varon just came up of Ebay and at an attractive price at that. It took all of perhaps one minute and I had bought it. It was not an impulse buy, because I had decided to get one quite a while ago, just not pay the retail price of about $4500. Ouch! The Makro Varon is a very highly corrected lens, certainly worthy of the name APO. However, perhaps most remarkable was that this was a lens built for a wide range of magnifications, which is unusual for industrial lenses, which usually have a very limited magnification range at which they are at optimum sharpness. The Macro Varon even has a separate ring to compensate for whichever reproduction-ratio is used, actually moving the inner lens elements around to accommodate that reproduction range. And, interestingly enough, its specs showed me that it could easily outperform the sensor of my fairly new Nikon D850. “Hmmmm, I mused. I’d like to see that.” And see it I did and pretty quickly too. But such a revelation soon led me to rethinking my bias against automated focus rails. It was not that I could not stack well, but I continue to get older and I am old enough as it is, and the little bumps, jars, and vibrations caused by me began to be more visible; they got in the way. Anyway, back to this blog. So, there I was, reading about the StackShot, when before I knew it my finger was hitting the return-key to order a copy. And to my surprise, the company (Cognisys) was right here in Michigan, only just up the road from where I live, in Traverse City. So, it was only a day or so before the automated-rail turned up at my door. However, learning to use StackShot was a bit of puzzle. It actually is very simple, but the manual is SO complete that finding the simple in it is hard. At least that’s how it struck me. I just wanted to get going right away and stack something, but although eventually that was easy, at first it was not so. And also, this device is meant for many kinds (or ways) of stacking. It took me a while to figure out what the name for what I wanted to do was. I finally did (Automatic Distance) and, as mentioned, it could not be simpler. Well, it could be explained more simply. LOL. As a software developer myself since the early 1970s, I recognized the kind of manual that indeed was precise, but is no beginner’s guide. I told them so. The problem was, IMO, how do I find what increment or step makes sense for the kind of close-up focus-stacking that I do. I don’t need the kind of detail one needs for stacking a bee’s knees, but I do need enough overlap of images to make the rendering of the stack smooth with no banding. Of course, I called the support line at Cognisys and spoke with a very nice person, only too willing to help. The problem was that at each question, each point where I was stuck, he pointed out that this or that particular choice was variable, very variable. So after fifteen minutes or so, I was right back where I started from, having to figure it out for myself. What’s new? Story of my life! LOL. And it took a while for me to run many stacks at different step-sizes to find a step-size that gave me what I was looking for and not one that took all day by over-stacking what probably couldn’t be seen. I wasn’t stacking a microscope image, but just a flower or two. I messaged Rik Littlefield, creator of Zerene Stacker, the stacking software I use, and asked him about over sampling. His response was that it won’t harm anything to make too many images, but it might add a wee bit of extra noise. After a few happy days with StackShot, here is where I am at. So far, it looks like the more detail you can get with the smaller increments with Stackshot, the better the result, within reason. StackShot likes to work in thousandths-of-an-inch or in millimeters or fractions thereof, your choice. I found myself working with MLS, thousandths of an inch, a setting of 20 Mls seems pretty good. 10 MLS is slightly better, but perhaps not worth the extra time, etc. A lot depends on keeping natural light even, which is hard with variable cloudiness. My thoughts on using the StackShot automatic-rail are positive. I have stacked for many years, always barely touching the focus barrel or whatever mechanism as required. I got pretty good at it, but also made little accidental bumps and knocks, which have never helped at all. And, as I drill down on these ultra-sharp industrial lenses that can challenge the sensor of even the Nikon D850, there is less room for user-caused error and a greater demand for regular precise increments. After many years of focus stacking, my most valuable learned skills are in setting up and composing the shot, although I have always done my best to move carefully through all the steps that focus-stacking requires. However, having tried out StackShot, I am convinced it has a lot to offer me in stability and consistency, leaving me more time to consider what shot I want to take. I am enjoying that. I have a fair amount of testing the Stackshot yet to do, but I am already getting a handle on it. By testing various step-sizes, I am already converging on what seems to work for me. I’m not doing photo-micography, but rather just simple close-up and macro photography. Of the many options that StackShot offers, the one I seem to be gravitating to is Automatic-Distance, which allows me to choose the granularity, the step-size, that works best for my work. In other words, I have one main step size that will be applied no matter what scope or distance I want to cover. Should that not be fine enough, I can easily make if finer, etc. The only caveat might be with spherical objects, where following the curve demands finer steps, IMO. So, the step sizes I have settled on should work. Physically, the StackShot is very well made, meaning it is robust, as strong or stronger than any other focus rail I have and I have ten or so. Its vertical profile for my camera is low, about as low as it could be and I have fitted it with my favorite RRS Arca quick-release clamp, the one with a larger knob. I can see no way that this is not better than what I have been doing myself by hand. And the program allows me to introduce all kinds of latency time, which I have done, so that at each movement of the auto rail, I take a second or so to let any vibrations created by the mechanism movement subside. The only problem, which has nothing to do with StackShot, is that since I use natural light, on a variably-cloudy day the lighting changes from moment to moment and affects the stack. To counter this, I would have to be standing there, slightly modifying the shutter moment-by-moment to keep the light stable. That kind of takes the auto out of automatic, but that’s the price we pay for natural light. It varies. So, my initial impression of the StackShot is not only good, but very good, almost something like “where-have-you-been-all-my-life?” good. I like it. As for taking the time I am used to spending stacking focus at the camera away from me, which I traditionally associate with meditative absorption on my part, it does not seem a problem. My hard-won skills are seeing the shot and setting up for it. With StackShot, I do the creative work and let an expert step through the mechanics while I do other stuff. Makes sense and seems fine. StackShot is easily rough enough to take into the field, provided you realize that it is heavy and if you don’t have any wind. Here in Michigan, I wait to see each day if there is no wind at first light. Rare, but it happens. A Hidden Surprise Surprise, surprise! There is almost always a surprise with new equipment. Using stackshot made one thing very clear. By standardizing the process of focus stacking (the mechanical part) all lenses were treated equally. It’s true that I always did my best to incrementally stack focus as carefully as I could. But, I cannot pretend that on any given day, I may have stacked looser or tighter, even or less even. I can only guess at the variation. But one thing is clear so far from using the StackShot and that is that the regularity of increments (the step size) reveals more clearly than I have ever seen the true or actual difference between any of these highly corrected lenses. It is clear that some of these lens differences were veiled by the more organic (sloppy) process of stacking by hand and not by auto-stacking. However, by regulating the stacking process, it creates a much more level playing field. And I found it very easy to see the differences between lenses, many of which I could never before be certain about. And so, whatever else auto-rail stacking provides (and there is a lot) a wonderful bonus in allowing me to see more clearly than ever how lenses differ, something I have always strained to see (regardless of all the graphs) for myself. By stacking in a more regulated manner removes (at least for me) a veil that has been obscuring these difference all of this time. Below are a couple of tables that might be useful. StackShot likes to work in thousandths-of-an-inch or in millimeters or fractions there of. 1 Millimeter = 39.3701 Thousandth of an Inch 1 thousandth of an inch in is equal to 25.40 μm Thousandths-inch TO MILLIMETER 10-mils = 0.254 Millimeters 15-mils = 0.381 Millimeters 20-mils = 0.508 Millimeters 25-mils = 0.635 Millimeters 30-mils = 0.762 Millimeters 35-mils = 0.889 Millimeters 39-mils = 0.9906 Millimeters 39.37 mils = 1 Millimeter MILLIMETER to Thousandths-inch .25 MM = 9.84 Mils .333 MM = 13.11 Mils .5 MM = 19.685 Mils .666 MM = 26.22 .75 MM =29.5276 Mils 1 MM = 39.37 Mils 1.25 MM = 49.2126 Mils 1.5 MM = 59.055 Mils 2 MM = 78.7 Mils 2.5 MM = 98.42 Mils 3 MM = 118.11 Mils 3.5 = 137.8 Mils 4 = 157.5 Mils 4.5 = 177.2 Mils 5 = 197 Mils Here are three example images, both done with StackShot, one with the Schneider Macro Varon f/4.5 and another with the APO-El Nikkor 105mm f/5.6. A third one is with the Nikkor “O” CRT lens. Also, a poor-quality shot (shot at night in bad lighting) of the StackShot controller (Vecro-ed to a post) and the basic StackShot setup. Note the RRS Quick-Release Clamp with the large knob.

  5. On my seemingly-eternal search for interesting lenses for close-up work I could not help but come across the Schneider Kreuznach Macro Varon 85mm f/4.5 CAS lens, if only because Schneider promotes the Macro Varon all over the place. And that’s a lot of promotion for a lens most photographers have never heard of. Well, I heard about the Macro Varon and searched it down to its price tag of $4500 and that set me back on my heels a bit. I don’t need a new lens THAT much. Well, perhaps a Zeiss Otus or two would be alright. I did make some calls, sent out some email requests and finally found that the Macro Varon could be had for somewhere in the mid $3K range brand-new. Well, of course that just sent me to Ebay looking for used copies. However, while it has happened, the Macro Varon does not show up used on Ebay very often, in fact hardly ever. Well, that limited my searching. I did find out that one sold on Ebay some time ago. Again, I spoke with Schneider reps about the Makro Varon on the phone and finally just let it go. It’s not that I don’t have other lenses that I might buy. LOL. And for those of you foolish so think I’m rich, guess again. I sell old equipment to buy new equipment as I go along. I just do it methodically. To make a long story short, recently a good friend sent me a message that there was a Makro Varon actually on Ebay for $1500. Well, that turned the corner for me and I bought it in about 15 seconds from receiving the message. It came from China, was used, but looked in decent condition. When the lens finally showed up at my door it was obviously brand new or in mint condition. However, it came in a strange industrial lens-mount which held the lens captive with three very tiny screws. I exhausted my collection of tiny screwdrivers, flat, Phillips, and torx (star). Then I called the local optician and gear-heads and no one had a tool that small. Well, that was disappointing, since I had no way to mount the lens without removing this big clucky adapter that gripped it first. Then I went salvaging through dozens of boxes of camera-related stuff and finally found a set of tiny torx drivers, but none of them was small enough to work. But, there was one (tiny) hole where a missing torx wrench should be. Where was it? And sure enough, in the bottom of my box of Cambo Actus parts was the tiny torx screwdriver and to my surprise, it worked! I had the lens mounted in a few minutes and was good to go. Now, I wanted to find out if this lens is best mounted directly to the camera and the camera placed on a focus rail, or should the lens be mounted directly on the camera with a small helicoid to focus with. The lens itself has no way to focus. It has six aperture blades (I wish there were more) and It has f/stops from f.4.5 through and including f/8. It does have something special, however. The Macro Varon has an additional ring on the barrel that allows me to adjust the floating lens parts in the lens to fit a particular magnification ratio 0.5x to 2.0x. This compensates and suppresses aberration depending on the magnification ratio. The only other lens that I have that has such a ring is the first edition of the Nikon Printing Nikkor 150mm APO f/2.8. These rings actually work. Another rather unique feature of the Macro Varon is that on each individual lens, during final adjustment, a tiny drop of red paint is placed on the rim of the barrel that allows (when the M42 adapter is screwed on tight) us to orient the particular lens to the camera sensor orthogonally, at right-angles. This is red dot calculated and optimized for each individual lens. Anyway, I soon figured out that (at least for now) I get the most play out of mounting the lens on the Cambo Actus Mini View Camera. Next, I had to decide what kind of hood would be best, since my first shots (made without a hood) lacked a bit of contrast. I tried both flared and narrow-tube hoods and finally fashioned one from the Nikon K-Ring set, one K5 plus two K3s all screwed together. They made a nice tubular hood that seems fine so far. Mounted on the Cambo Actus Mini, I soon found out that rather than the large (special order) cambo bellows I normally use that prevented me from getting as much field of view as I wanted with this lens, so I substituted a short bellows, which is fine because I do not need as much room with the Macro Varon anyway. That helped a bunch. I could also look into using a tiny extension/helicoid mounted directly on the camera, but I doubt that I would gain much, and moving the rear-standard on a view camera is better for stacking than using a helicoid. Anyway, I am up and running. Here is a quick photo of my setup, the Nikon D850 on the Cambo Actus Mini. On that is the Schneider Macro Varon 85mm f/4.5 lens adapted to Nikon mount, with a hood made of several K-rings. So far, so good. And I include a couple of early shots taken with the Makro Varon to give you an idea of what this lens can produce. This setup is not hiking-material, but certainly can go outside to the fields and meadows, at least if there is easy access so that the gear does not have to be carried far. The lens itself would be easy to carry for hikes, but would have to include some form of helicoid to focus or be happy with a DOF at F/8 and fixed focus. Anyway, I’m checking out the Schneider Macro Varon 85mm and would be interested in any other user’s experience.

  6. I am engaged in aquarium photography of small colourful shrimp measuring between 10-20mm in length. With a new camera, the D810, I have tried some slightly different options. One set consists of Nikkor 105mm 4.0 AiS with a K3 ring and an P-Nikkor 105mm 4.0 for bellows, two classics in other words. That solution is quite sharp and the viewfinder is bright so the focus is easy to adjust. The picture of the green shrimp is taken with this combination. ISO 64, 250 / sec. Aperture 16. A working distance of approx. 10cm. The next picture of the red shrimp in the moss is taken with Zeiss 135mm 2.0 which has a close-up of 80cm. But using a polaroid close-up lens, Polaroid 250D, the same as Canon's equivalent, and some cropping. The depth of field is always a problem. ISO 64 320 / sec. Aperture 16. Both images taken with two studio flashes. A really crisp macro of 90-100mm would be nice to try! flic.kr/p/Ww3wq8 flic.kr/p/Wdq4vh

    Macro Fun With Olympus E-M1

    Over the summer I have been using the 5D-III to shoot a lot of macro. The weight of the big rig can be a tiring experience in the Texas heat. Not to mention, the size can be a detriment when approaching insects. I’ve been working on an illumination strategy for the Olympus EM-1 to better utilize the size (lack thereof) advantage the camera has over the Canon. When I started out I limited its use to tripod work and then graduated to a large diffuser box and flash clamped to the camera via ARCA plates and clamps. This setup defeated the size advantage and just added unneeded weight. Time to rethink the plan… I finally got around to buying a MetaBones EOS-to-M4/3 adapter. The native 60mm Olympus macro lens is a fine piece of glass but I wanted more working distance. Time to pair up the Sigma 150mm macro. It’s the older version, no image stabilization, so the weight is reasonable and the working distance is twice as much. This is a good and bad thing, good because I have more working room with skittish insects. Bad because diffuser/ flash need to be extended on an arm to be at an effective distance. Enter the wireless Phottix Canon Triggers and 430EX-II with diffuser. I was free to position the flash by hand anywhere I wanted. This really opens up lighting options for me. To start off with I have been using the camera on a tripod and holding the flash. These pictures are an example of the effort. I have been practicing holding the camera with one hand and the flash with the other. This technique uses the camera’s lack of weight for positioning (diffused flash illumination and camera) advantages: This is a one-handed camera shoot. It was harder than I thought it would be. A lot harder than sitting on my field stool popping off shots of flowers and such with my knee as a support. I was able to position my right shoulder against the tree and this added much needed stability. For 1:1 or there abouts shooting the 60mm macro with hood doesn't offer enough working room for me to properly position the flash camera side so I put it on the opposite side of the subject. I shot some frames and adjusted the angle so there wasn’t any stray glare entering the lens. I was surprised by the fact I had a harder time keeping the 430EX II flash steady and in position than the camera. Just about the time I got everything coordinated the ‘pede found a hole in the trunk and headed off into the abyss…
  8. So...Inspired by Michael Erlewine and a few other, I found and purchased a Repro Nikkor 85mm f1.0 lens. I have a Heligon f1.0 lens, but this is a beast of a different color. I tried it out for the first time today, and it is amazing. I can see where selective focus stacking. as Michael does, could produce some tremendous images; however I am typically a grab shooter working outside without a tripod. Well, we'll see where this leads, but I sense enormous possibilities for unique images. Here is my first try--blueberries in my garden at f1.0

    New member, first post. Excited to find an active photog group that isn't just on Facebook! Shot with a Canon 7D MkII & EF 100mm f/2.8L Macro (Sorry, the image appears to be soft. Will see if there is a thread that suggest settings for higher resolution images on this forum.)

    Fisheye Macro

    I think it works. It also looks like this lens has a nice bokeh. All images were taken in manual focus, focusing the lens at the closest distance. The petals were touching the front element! D7000 10.5mm 2.8 • 1/2000" 2.8 100 ISO 1 2 D7000 10.5mm 2.8 • 1/1250" 2.8 100 ISO 3

  14. Couldn't resist, Fons. Sorry Bishop of Llandaff, this evening. Just blooming. I wanted to compare the 100/4 and the CRT 55/1.2. Micro Nikkor 105/4 f8 CRT 55/1.2 f8, cropped to similar size, approximately
  15. Only 55 3.5 and M2; 55 3.5 P/M2/extension tube (about3-4cm);
  16. While the majority of my shots are candid, occasionally I do make some planned images as well. Complete visualization is not my forte, I start off with an idea and then play until it develops to a state I like. The following is an example of the process that I go through. I wanted to continue the theme I started last year with the Little Espresso People Calendar and after a long hiatus I finally got my lazy butt moving. Here the idea was to have a model figure climb a sugar cone (of course one of the follow on images will feature a burning sugar cone...). It starts off with a seamless black background (art supply stores are much cheaper for this than photo stores), the sugar cone and a climber (H0 model figure): The calender images where all done in flat light illuminated by two or three LED panels. For the new stuff I wanted a bit more interesting light. Therefore I used a gelled, shielded flash with a wide straw to provide some sort of warm spotlight on the climber. Hmm, that background is not nice, so what should I do? I went through my images and cropped a bit of sky out of an image (basically a harvested field next to our village) and added that and some sugar for the foreground: Just placing the A3+ print (on matte paper to ensure there is no reflection from it) behind the sugar cone did not work, I needed to hold it up by gaffer tape, in a slightly bent fashion. The whole setup looks like this: Spotlight flash from the left (in SU-4 mode), base front light by LED (YN300 with Roscoe frost diffusion) and then some top light by flash (triggered with pocket wizards). But maybe I should use a sunrise? The sunrise clouds are from Madeiras third highest peak, Pico do Arieiro where I went one morning to see the sun rise. I also changed the angle at which the cam looks at the climber, it seems to work a lot better on the side. But how can I have climbers without rope? I needed a thin thread with a strong color that mimics typical climbing gear. My thinking was, regular cotton thread has enough tension to not fall nicely, so I have been mulling over alternatives (Silk for example). Still, I did try a regular cotton thread and it seems to work nicely so far. So here are my final two images: The spotlight was moved further away to illuminate a bigger area. All images still SOC (D300+60/2.8G, F11, ISO200, 1/40), no crop, adjustments, cleanup or tuning yet, that is the next step. cheers afx

    Diving in

    I've never shot macro before but recently felt the urge to try it out. On Bjørn's (nfoto) recommendation I acquired a very nice Micro-Nikkor 105mm f/4 and had a chance to test it yesterday. I think I'm in love with this lens already. I'm just getting my feet wet in the macro world so these images aren't anything spectacular but I'm having great fun diving in.
  18. Interesting situation on a blue flower I cannot name. This completely albino white spider had just caught a common housefly. I have no idea how, as I could se no web anywhere nearby. Judging by the looks of the spider though, it seems to be a mean hunter. Captured With a Nikon D4, Micro-Nikkor AF-S 105/2,8 at f5 and shutter 1/200th. Hand held.

  23. There's a story behind this Yellow Orchid, of course. The previous Sunday was our anniversary, our 19th, an odd year indeed. On Wednesday, Linda, realizing my birthday is coming in April, associating the two events, exclaimed, "OMG! I forgot our anniversary!" My answer, "Whew, I did too! I'm glad you forgot it too! We'll go out for dinner at the [local] Inn tomorrow." On Thursday, Linda brought home the orchid as a present for me. Finally, due to our extended winter weather, I'm inspired to get back into doing some closeup work. And the dining at the Inn was fabulous! --------------- D800E, CV-125, Acratech Universal-L Bracket, Novoflex Castel XL Focus Rail ISO=100, f/5.6, 1-sec 38 files taken at 1 mm increments compiled in Zerene Stacker.
