I have Adobe Photoshop 6.0. Im trying to find out how to stack 2 images, or more using this program. I have tried it before with tutorials but mine never work, i either get the same image or a black picture. Can anyone explain in detail how to stack 2 film images?

Matthew,
Sounds to me like you were 99% there... :-)
The layer method needs to be changed, as well as the opacity.
If you had used Difference, you should have ended up with a black image (they would cancel each other out, this is how the 'digital' folks do dark frame subtraction)...if you had left it on Normal, you would have seen the top image (since the images are nearly identical, you wouldn't see much of a difference).
Try using Screen and, for two images, I would set the Opacity between 80% and 95%.
Remember, you want to stack two different images...don't stack the exact same image on top of itself.
Good luck,
Forrest
