Digital cameras are smarter and more capable than film cameras, but underneath, they still work the same: light hits an image sensor, and the camera’s interpretation of that light is the image you see. Sometimes the camera (or the photographer) gets it wrong, and the picture suffers. But once you’ve mastered a few tools found in Adobe Creative Suite 3, you can make adjustments to exposure and contrast. You can also do it nondestructively, making things easier to fix in the future if you change your mind.
