Is there any software (or feature in Photoshop) that will align one image
over another image that is almost identical? Ideally it could align a blue
image over the matching part of a red and green image.

I have some negative film, (accidentally) developed in E6 chemistry. The
result is that the red and green channels are very dark compared to the blue
channel.

I can adjust the gain (really the exposure) in NikonScan to get either the
red and green channel OR the blue channel, but nothing I have tried produces
an image with detail in all three channels.

As a result, I have 108 images with valid red and green channels, and 108
matching images with a valid blue channel. I need to align them properly,
preferably without having to do the whole thing by hand.

Thanks,
Aaron Queenan

Try alt.graphics.photoshop or comp.graphics.apps.photoshop

Sorry, my mistake. I see you have already cross-posted :-(

Drag and drop while holding the SHIFT key should align them perfectly.

Any photo editor that supports layers will do what you want, and
PhotoShop (and Elements) will do this.

The only thing I can think of would be to copy and paste in different
layers. Then adjust each layer for optimum. This adjustment should be
recorded as an 'Action' in Photoshop. Then it will be a simple matter of
calling up each picture paste and set the Action.

Yes - do what Johan says. Sheesh - it's not rocket science.

Well, that aligns image to center of layer, but does not necessarily
align one image to the other, if they aren't perfectly aligned to begin
with in reality (from camera,scanner, whatever originals).

You can of course reduce opacity of your top layer temporarily to see to
align but one is still doing it manually.

Not to mention that most of the methods suggested seem to be limited
to single-pixel resolution (you really want subpixel resolution) and
all of them seem to ignore the possibility of rotation or warp in
addition to a shift. A warp could come about from any inconsistency in
scan rate from frame to frame.

Unfortunately, the x,y ofset for each image is different, because they were
scanned separately, so I'd really do with a program that aligns them
automatically.

Of course, I'd rather not pay too much for it, because it would only take a
few hours to do the job by hand, after all. *sigh*
