When you say ISO your setting that at 800-1600?
When you say F-stop you saying 1/8 at F5.6?
Whats your Focus set at: one shot, AI focus, AI Servo?
What is your White balance set at?
I think I'm getting it, Also I assume you using a tri-pod having a 1/8F stop
What F stop do you use when the camera is in your hand?
You da man. Also I'm using the same Macro lens
The following is my advice for taking good pics. Obviously I spend a lot of my picture taking time with everything on auto, just snapping pictures and hoping for the best.
ISO
I set my ISO at 800. ISO used to describe the film that was in the camera. For digital cameras it is setting the sensitivity of the capture device. The higher the ISO the less light is needed to take a picture, but the quality of the image is also worse. If you use a higher ISO you will be able to take pictures with a faster shutter speed. In a reef tank, even though it seems like a very bright object for a picture, it is actually pretty dim. To get good pics that aren't blurry you need a fairly high ISO.
F/stop
When I mention an F/stop of 8ish, I am only talking about the size of the opening on the lens. The macro lens that we have can go from F2.8 to F32. A small F/stop means that the opening of the lens that light goes through is large (it is exactly the opposite of what you would expect). A large hole means you need a shorter exposure time in order to get enough light. A large hole (aka a small f Stop) also makes things in the background seem blurry. Sometimes you want the effect and sometimes you don't.
I usually pick my F/stop before I pick my shutter speed. I usually use an F/stop of 11 or less. On the other hand, if you are taking a full tank shot, you probably want the foreground and the background to be in focus, so you would use a higher F/stop.
Shutter Speed
Once I have my F/stop set to what makes sense for the shot, I set the shutter speed. To do that I hold the shutter button down half way and the camera's light meter shows you on the horizontal bar whether you have not enough light, the right amount, or too much light. Then I adjust it until it is just under where it thinks it the right amount. I have found that the camera gets tricked by the tank and tries to get you to make things too bright. At this point I check to make sure that the shutter speed isn't too long. If it is 1/16 or longer (1/8, 1/4 etc.) then I usually lower the F/stop(1/32, 1/64 etc), because 1/16 or longer is going to be blurry because there will be too much motion. Once the shutter is fast enough, I start shooting. As I said I usually end up with a little faster than what the camera recommends, but as I am shooting I will take one pic with the shutter where I think it should be, then I raise it and take a pic, then I lower it and take a pic etc. Then once I have everything on the computer, I just pic the one that looks the best.
Focus
Generically when taking tank shots, my focus is set to AI Servo. I normally let the camera do all the work of focusing. However, if I am trying to take a true macro shot, I flip the switch on the lens from AF to MF and do all the focusing myself. When doing that, I usually take a picture that looks in focus to me, then I tweak the focus by as small of an amount as I can and take another picture. I do that over and over so that hopefully one of the shots will turn out to have perfect focus. I do this because I find it very difficult to try to focus something when you are only looking through that little viewfinder.
White Balance
I set my white balance to AWB. In my opinion the camera does a good job of figuring things out. There are some corals that look a little better with the camera's white balance, and some that look like crap, but all and all I find it good enough to go with. In the future I might mess around with white balance, but up to now I have been too lazy.
Tripod
If I want good pictures I use a tripod. You pretty much can't get great detail shots without one. Also I use a remote to take the pics. If you are manually pushing the button, it is going to be a bit blurry. I know it is a pain to haul out the tripod to snap a handful of pics, but it really does make a huge difference.
Angles, Movement, and Lighting
Lastly, here are a couple of things to remember. You can't take an in focus pic from an angle. You need to shoot straight on, otherwise the glass/acrylic distorts the image. This is a pain, because some things in your tank you can't see from straight on (oh the woes of a giant tank lol), and also we both know that sps look better from above, because that is where all that light blocking pigment is located. That is why a lot of people take top down shots.
Also, corals are a lot easier to photograph than fish, because fish are disobedient jerks. You tell them to sit still for 1 minute and they simply ignore you. But keep in mind that most corals DO move. That means you have to keep your F stop low, or your shutter speed fast, or your ISO high (or some combination of those) if you want good pics.
Lastly, mess around with the lighting. In my opinion the best shots are where you have all your actinics on, and a halide on, but not the halide that is directly over the area you are taking a picture of.
