Here's an example qpid.
Now by no means am I a PS expert, but some basic stuff can be quick and easy. On this I just lassoed the flags, hit inverse, and desaturated the rest of the photo. Goofed around with levels to adjust contrast and brightness. Then, while still on inverse, played with the color balance sliders to get a nice sepia tone. Then went off inverse and bumped up the saturation of the flags a little bit. I think the whole process took about 5 minutes.
Play around with this program and you'll learn something new constantly.
