Hi, I compostited a poser render onto a vue image that I had rendered, then I moved the poser render.  Now I have redone the poser render but because the one in the photoshop doc has been postworked, I only want to erase a little of the postworked layer and have my new poser render underneath that layer exactly aligned.  Is there some way of copying the coordinates of the moved picture so it matches my new poser render, or is it just trial and error?

Unless someone knows something I don't... there is MUCH I don't yet know... I am afraid you are stuck doing it "the hard way" a good trick, though.. place "something" at a pre-specified point in all images, to give yourself a reference point.. it need not be much more than a small "spot" in the image.. preferably, something you can remove later, in the final. Lou.

Ha, I didn't think I would need to do it so I didn't do anything like that, but guess what, i just moved it around a little and it slotted exactly to the right spot.

COOL!.. good going.. I have had to play with map overlays for hours at a time. Lou.

mm maybe i got lucky but it was the same sized image as the previous ones so perhaps it moves in little tiny increments.

Which version of Photoshop? I can't recall when it was added, but most versions I've used have a Layer>Align menu with options to align to different edges which should do the job with old and new layers selected.

CS3 - I didn't know about that one but it could be really useful.

if the two files are the same size and resolution you can choose "duplicate layer" and choose the other file (both files need to be open) as the target. it should place the layer in the exact same position as the source file.

another trick is to change the colour mode of the placed layer to "difference" and move it around until it is mostly (if no changes, then completely) BLACK. this means all the pixels are aligned. you can then switch to whatever colour mode you want. (remember to "upper" layer needs to be set to Difference or you won't see the effect)

hope this helps

now that difference thing is a neat trick.  But yes the two files were the same size and resolution.  I didn't know about open as target.  never noticed that one.

This youtube video demonstrating the auto align command might be useful to you.

thanks.

that was pretty amazing. Glad I watched it.

For future reference: In the document you were working on select the layer you moved then press and hold "Ctrl" key and LMB click in the layer's image icon to select the boundry of the moved layer. Then using the "Move" tool and pressing/holding the "Shift" key, move the new image document onto the document with the moved and selected layer. This should center the new image layer directly on top of the moved layer.
