Photoshop question

[coops]

My computer is a little old and makes editing large images tedious. It occured to me that I may be able to do color correction levels on a low resolution image, save the changes and apply them to the larger image file. I cannot see a way of doing this and was hoping someone here may know if this is possible.

That was really interesting. Thank you Richard.

Brilliant. I was wondering about that.

John Paul Caponigro's book describes doing this as well. Having several smaller files open to see teh effects of changes and them applying them to large final files.
