Flat field images

[Daniel Walsh]

Hi everyone, I have a question about stitching flat images, i.e. camera does not rotate, instead, subject is moved along in front of the lens.

I'm using an 85mm lens on a mirrorless camera at approx. 1m away from subject.

I have 3 images, when I ask PTGui to align images, only one image in shown.

Help appreciated.

Did you read https://ptgui.com/faq#6_5 ?

PTGui may not have been able to generate control points. To diagnose
this more accurately, we would need to look at the images. Half size
jpegs would do. Please use wetransfer, dropbox or similar to provide them.
