This is sort of recent. Originally shot on Canon digital, but had the product - the turbos from the winning Audi at LeMans 2010 - for a few days, so bought a box of T-Max100 4x5 and shot twenty sheets - two sheets each of ten focus slices. Drum scanned one set at 2667 ppi on the Howtek. Photoshop would get through an Align Layers command in an hour or so, and even made it through a Blend Layers, but it looked like crap, so I then exported ten identically sized layers into Helicon Focus, which crunched through the files but still looked like crap, so I hit it for an hour or two every few days for a month or so, gradually blending focus by hand. A 30x40 test print is looking really sweet at this point, with a depth and luminance that the digital could only dream about.
