P: Auto Align Layers slightly misalinged

I have posted about this previously, but perhaps someone has new sugestions.

I am shooting mutiple exposures of the same fixed image. The images have been taken on a Canon 5D Mk IV on a sturdy tripod with a remote shutter release at the same aperture. I use BBF to reduce any in camera movement.

Because I want to blend those images, I need to ensure the frames or layers are all 100% aligned.

As I shoot and edit a lot of images, I like to speed up my worklow as much as possible by creating preset 'actions', and Auto Align Layers is one of my 'actions'.

Before I apply this preset, and when I zoom in on the 3 layers, all 3 appear aligned. However, when applying >Auto-Align Layers>Auto this misalignes the layers (see attached images).

'Nudging' as as been suggested before is time consuming.

All suggestionss for a solution welcome.

I agree that this is an issue. With all the precautions that you're taking, do you need to auto align. I stopped doing that, as often I didn't need to, and the few that were somehow out of alignment could be nudged.

Yes, you're right, and it's a bit annoying. It's often a couple of pixels off, and I've made it a habit to always hit ctrl+1 to check and nudge when needed.

Note that the algorithm itself works perfectly. The alignment itself is usually very close to perfect, even subsampling (less than a pixel) when necessary - it's just that it often puts the final resulting layer a few pixels off. Once nudged with the arrow keys, it's dead on.

I've been meaning to post a bug report but never got to it.

EDIT - I'm not moderator, but maybe someone who is could move this to "Bugs"?

I work with real state photography and have had some problems with auto-align in photoshop. Photoshop auto-align simply doesn't work as it should and does not align photos correctly.
Someone else has had identical problems?

If so, how did you solve it?
