> 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?

I'm sure they registered the images.

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.

It should be much easier to take overlapping pictures and "seam" them together.

I assume there are software tools for that.
