    One of the nicest houses I have photographed this year. A really simple, but wonderfully flowing layout from front to back. Shot with Olympus E-M1 and Leica 8-18mm. Edited in Lightroom and Aurora 2019.

    I must say that the South African houses that you have shown us are very impressive, as is your presentation of them. I just hope that the Estate Agents and their clients apreciate your fine work.

    The key to what I'm doing is the Sigma sd Quattro-H camera - there is no interpolation with adjacent pixels when shooting in B&W mode as there is with Bayer or X-Trans. That means that every pixel is indeed an individual recording of its unique part of the image, which in turn makes stitching accurate as the program can match individual pixels accurately. The lens is less of a concern, more importantly was to get a lens that had a wide enough image circle to utilise the Hartblei P6 shift->M46->Sigma SD adapter and flat field rendition which the Zeiss Jena 2,8/120 medium-format lens with 1.2:1 extension tubes supplies perfectly for these 100MP scans. Using this setup with an LED panel stuck to the copy board and a Durst 1200 Laborator Neg holder on top of that means that nothing changes between the camera sensor and the neg during the exposure - one simply shifts the adapter after taking an initial centre-of-neg shot between 8mm and 11mm (as appropriate), and then it takes a further 9 exposures rotating the adapter to appropriate click-stops around its 360° circle and is perfect for 6x6 negs. Focus never changes during this, nor for subsequent negs, so after a bit of practice the procedure becomes very quick indeed. The slowest part of the procedure is Sigma's notoriously slow SPP raw processor, but as everything is constant I just set the processing to batch with a custom preset and get on with something else while it trundles away in the background. It takes PTGUI approximately two minutes to add the converted TIFF images, crop, stitch and save the pano. I only invert to positive after all this is done and I'm cleaning things up in Photoshop (film reintroducing the joys of dust and micro-fibres on the negs requiring spotting). All that said, for my usual copy setup I use my X-T2 and Zeiss Touit 2,8/50M Makro lens, for larger originals I take segments by shifting them around the copy-board and stitch them for a higher resolution end result. For any original A5 or smaller a single 24MP exposure is usually more than adequate, though. Here's a picture of the final setup, the lens at rear on the copy-board is a Sigma 70mm macro which I use for single-frame proofing of negs - it's quicker to use as it couples with the electronics of the camera.
