I may sound dumb, but what is "underexposed by a stop" mean? Did you black out the background with editing? Thanks
LOL, Maybe I just need to take a photography classIf your exposure is 1/60th @ f8, you shoot it at f11 or 1/125th exposing the image a stop under the correct exposure.

Underexposed by a stop means that I shoot with a shutter speed that is one stop faster than the one that the camera's meter suggested is the correct exposure. For example, if the meter in your camera suggests a shutter speed of 1/60 sec., moving the shutter speed to 1/125 sec. (twice the speed) will underexpose the shot by one stop, i.e., make it "darker." Moving the shutter speed to 1/30 sec. (half of the speed), will over expose the shot by one stop, i.e., make it "lighter."
Aperture determines depth of field, i.e., how much of the image is in focus from front to back. As the f/stop, or aperture, gets higher (moving from f/8 to f/22, for example), the lens opening gets smaller and the amount of the subject, from front to back, that is in focus increases. If you take a series of photos of the same subject (a fence, for example) at different aperture settings you'll see how the amount of the subject that is in focus changes with the aperture setting.
For these basic photography questions, it would serve you well to read a book or use one of the hundreds of websites devoted to teaching the principles of photography. Also, at some point, the only way to learn is to take your camera and go shoot a bunch of photos of anything, make some notes, and start to learn what happens when you change settings. Note that it's much easier to learn these things if you're taking pictures of a building, tree, or a fence than it is to learn the basics while trying to do close-up photography of corals.

Gary, in the presentation you gave at our local club, (IIRC) you said that you generally shoot with an ISO of 400. Have you experimented at higher ISOs with the newer cameras and their ability to shoot at higher ISOs without getting grainy?
Thanks,
