> To create this huge image, the painting was photographed in a grid with 97 rows and 87 columns with our 100-megapixel Hasselblad H6D 400 MS camera.
Looks like they had the ability to move the camera precisely to one of 97x87 grid positions. I wonder if they had any headroom in the precision of that movement. Could they have used a lower resolution but much cheaper camera and compensated by taking, say, a 200x200 grid of images instead?
Lower resolution yes, but one thing with the 400MS or any multishot back is that it can shift by one or 1/2 pixel to collect full RGB color info for each pixel, very important for conservation work.
