How to add new images and align to a set of photos I previously aligned

[Matthew5EDD]

I'm doing a project where I take the same photo of a construction site every week. I aligned the first 10 images (from 10 weeks of work) using auto-align, and it works very well.

The way I do this is, start a new Photoshop project, File-Scripts-Load Files Into Stack, select the 10 photos, click 'auto-align source images' box,  I create a frame timeline, one second per frame, it looks really good because the images are aligned to each other.  I save the photoshop file.

Next week, I add another image (by dragging and dropping the image), and try to align it to the prevoius 10, but it doesn't work: it's as if Photoshop is ignoring the 11th image, it doesn't adjust it at all to fit.  Any ideas?  Thanks

Are you using a fixed position security camera images.  Why would image taken so far apart  in time align. Did you perhaps trim/crop the first 10 image stack after after they were auto aligned. If so not drag in number 11.  Stack the 11 images load layer into a stack auto align option.

Hi JJMack, these are not security camera images.  Yes I did trim and crop the first 10 images after they were auto-aligned.  I suppose this is the problem (trim/crop)?  So each time I add a new image, I have to load all 11 again?
