Well with the joys of digital, you could take two identical pics with different exposures and stitch them in photoshop if you really wanted a perfect shot.
Or if your camera supports it, it can take the same shot and apply different exposures to it and end up with 3 of the same pics that look different.
this was great advice,and got me thinking i only need one picture and with the joys of photoshop you can change the brightess and contrast and settings with photoshop and put it together that way aswell
Photoshop is a great tool, but don't rely on it too much. You can get the most out of an image with just a good eye and knowing the tools within your camera. Composition and exposure are everything, Photoshop comes later.
