More people than ever before are using digital SLR cameras.
When film was the primary medium people used to make photos, you didn't get to see your photos until they were printed. If you didn't do your own darkroom processing, you relied on the photo lab to develop the negatives and make the prints for you.
Now, dSLR photographers can see a small version of their photo right on the camera, but if they want those photos to display nicely on a computer monitor, somewhere online, on some other digital device or have it printed, there are choices about camera settings that need to be made. Those choices can have a big impact on how sweet your photos look and how much editing you can do to them and still have them look nice.
Each camera has many settings, and most are covered in each camera's users manual, but 2 of the more important, somewhat esoteric settings, are worth taking a closer look at.
