Hi
another way to achieve the same result (but with a bit more control):
open the image
turn into a RGB image (if it isn't already)
select image-then apply image from the drop down menu
next choose MULTIPLY as the blending option
Choose red for the channel
play with the opacity until you get the desired results.
if image is not dark enough repeat the above.
you can try the other channels to see which you like best.
I find the red channel a lot of times "cleans" up the colors especially if they have a red cast.
Please let me know what you all think
I like experementing, I am not a pro
