This image was shot with a Leaf 28MP back. The capture size is 30.5 X 23 inches at 300DPI and 362 MB. The insets are a single capture of the same setup and a golf ball at 100%. Take note of the huge difference in depth of field from the single capture to the stitched image. At 100%, the balls do not fit on my 24″ monitor (set to 1920 x 1200). Still life with single capture, MultiStitch image, and 100% inset
This photograph was shot with a Leaf Aptus 36x48mm, 33MP back on a MultiStitch. The native capture size is 34.54 x 25.83 inchesat 300DPI and 270.3M (8 bit). Shallow depth of field like this is nearly impossible with a small format capture.
This image was shot with a Canon 5D on a MultiStitch. The capture was 26.42 x 16.62 inches at 300DPI and 226.1M (16 bit; 8 bit was 113.1M) Effective chip size is 42 x 66mm or 1.65 x 2.6 inches; larger than the chips in most MF digital backs.
The image below was shot with a Canon 5D MKII on a multistitch. The capture (after cropping edges) is 21.9 x 34.3 inches at 300DPI and 193.3M (8-bit). This equates to roughly a 30MP capture from an effective chip size of 42 x 66mm. The largest single capture chip as of late 2011 is 40.3 x 53.7mm.
This image was shot with a 5DII set up for a vertical capture. After shooting the 4 images I used rear shift to shoot extra frames on the left and right. To maintain 6mm overlaps I shifted 18mm each way. The 8-way image is 34.3 x 41.7 inches at 300DPI and 736.5M (16 bit) (368.3M in 8 bit). The effective chip size is a whopping 78 x 66mm -an aspect ratio close to 4×5 film. There was some tunnel cutoff in the outer images, but the PTGUI masking function allowed a seamless stitch.
YOU DO NOT NEED A NEW DIGITAL BACK!!
