I am now going through the HPE PE3 book and would like a suggestion(s) on how to best handle this in PSE3. I have a digital photo of a sunset over the ocean. I love the RGB seperation power tool and would like to use it to adjust
color/contrast separately for the sky and ocean portions. Do I have to split the file with the photo into 2 separate files: sea and sky, and operated on each separately and then recombine? Is there an easier way? Using the RGB
separation tool requires a flattened file to operate on so I do not see how to
keep open two separate layers with different portions.
Also, for the separation I have tried the polygonal lasso along the sea/sky
boundary and selected the sea; then copied it into a new blank layer so it only has the sea. However, when I come back to the background after the paste, the selection area is now gone. I would like for it to remain on (active in the background) I can do an inverse selection and get an exact match of the other section (sky) to put into still another blank layer. If I have to do the selection over again, I find I do not get the exact same points and the border between sea and sky do not match as well as I would like.
Thanks in advance to help/advice,
Charles (not new to photography but new to PSE3)
