Thanks for the comments about my photography larry and schloaty.
"Are you using a close-up lens attachment for your macro shots? The DOF on those are awesome."
No I do not use any lenses. I use the camera macro mode which usually is a flower symbol on the camera. This allows the camera to focus very close to an object.
DOF is achieved with your F stop. The higher the F stop # the larger your DOF, (more area that will be in focus) but you sacrifice light to do it. Meaning, F8 gives you the best DOF, but your shutter speed will increase, (open longer) to make up for the loss of light entering the lens. Making camera shake harder to deal with, unless it is a very bright day, a fill flash is used, or a tripod is used.
F2 gives you the least amount of DOF, but the most light entering your lens, and quicker shutter speeds necessary to expose the picture. Typically this is what you would want to use to "stop action" shots.
Most of the time when I take pictures I set the camera to manual mode and have to give and take with DOF and shutter speed to get the exposure correct for the subject I'm photographing.
Some cameras allow you to change your ISO setting. I will not get into this because I have notice that the quality of your pictures goes down when increasing the ISO speed, with digital noise, and to me not acceptable. I always use the slowest ISO setting available.
Sorry I kind of went into a writting fit, but I will use this on another forum that ask me to write something for them a few months ago, and have been putting off.
