The DigiTiler is a camera-mechanism+software (in on-going development) for large-format cameras that allows a photographer to efficiently “tile” an image projection, say 4×5 inches, onto 42 overlapping 1 by 1.5-inch full frame sensor captures (or 99 APS-C). I prefer Sony mirror-less cameras which have a short 22mm flange distance. View the latest DigiTiler images on Tumblr.
Benefits? Bayer sensors create color noise at the pixel level when missing color (each pixel only captures red, green or blue) is extrapolated from neighboring pixels. Therefore, you really need three (in practical terms) four pixels to create a true color point. A 24 megapixel camera is really only six megapixels to the purist. When shooting with the Digitiler you end up with around 300 bayer sensor (stitched) megapixels. That end result in a 75 megapixal true color digital negative. Compare that to the latest 50mpx Canon which ends up with 12.5 true-color images.
Here are a couple of sample images. The first taken with the Sony A7 with the second sharpest lens DxO has tested.
The following was taken with a 50+ year old camera with a lens made BEFORE digital cameras.
