Enhance rainbow in photo?

took photo of rainbow landing on a church doorstep. no neg. how to enhance colors of rainbow- narrow slight arch across half of photo. ? Have WOW 7 1click gradients but cant figure out how... make a path? stroke it? fill layer?

dont use the gradients!!!!!!!!

ok...... heres what i would do.......

firstly.. make a new layer
second.... make a selection around the band of the rainbow....
third.... hue and saturation and then colourize it to the colour you want it to be
fourth.... lower the transparency and fill levels until it lookes natural
finally... repeat for all seven colours of your rainbow

Hope that helps

Perhaps a link to the picture would prove useful in any advice we could give.

I agree with lazyroll but I would do it a different way. Make a hue/saturation adjustment layer and then set it so that the red looks really vibrant, just the way you want it (dont look at the other colors now). Then invert the mask, and use a soft brush to color in where the red of the rainbow is. Continue this for all the other colors/bands. I don't think it should matter too much if the masks overlap slightly, but if theres a spot where it looks bad, just draw some black on the offending layer mask. Then if one color looks too bright or not bright enough, you can lower the opacity of the adjustment layer, or change the valies for hue, saturation, and lightness within it. You might also want to make a brightness/contrast layer for the whole photo, if it needs a little boost.

Good luck and post when you're done - I want to see the results! :D

*edit - Actually first try just one hue/saturation adjustment layer (just up the saturation and maybe play with lightness) and one brightness/contrast layer. Mask both of them to just the rainbow. If the bands are big, though, your best option is probably seperate ones for each band (color).

OK- thought I was being smart to study a library of books before asking all you PS geniuses for help...THEN I think I pose an intelligent ?, get great answers and spend the next several days trying to upload the photo in ? to my ISP server for you to look at- hopefully so I can later post the results- and STILL HAVEN'T successfully made that FTP stuff work. Now I have a family problem demanding me so as soon as I get the photo "fixed" and manuever it to a page- I'll post it. THANKS again for the help!!!
