sorry for my grammar....

i mean shooting at Land (top side or normal shooting or Not in Under water shooting) and under water shooting ......it is have any setting??????
I think there is a little more to fool with underwater than top side. Just becuase you can get into trickier lighting. People have their own prefrences in which mode the shoot in. I guess it all depends on what you want to do. Some prefer Apeture Priorty mode, while others will move on over to Shutter Priority mode to stop action, and then other prefer Manual mode. Then you get over into Flash, i.e. TTL vs Manual. A good resource is Martin Edge "The Underwater Photographer". If you don't have, then it is a must get book.
I personlly use my strobe in Manual. Tried TTL ... didn't like the results. I'm comfortable with the Manual Mode on the SLR when shooting good VIZ, on a reef, and using a manual strobe. Then what you need to review is Exposure 101. There are 4 types of exposure controls: 1) F/stop - control the foreground and background exposures; 2) ISO - Also foreground and background exposure.; 3) Shutter speed - background exposure; 4) Flash - foreground exposure.
For Fisheye: Start with 200 ISO, F/stop F8, Flash 1/2 - 1/4 power, and the shutter at 1/200 (I speaking manual mode). Take a shot. If the background is too dark, decrease the shutter speed. If the foreground is too bright, then decrease the flash output. If everything is too dark, try bumping up the ISO or opeing the Apeture. With Macro, same settings, except go with a Apeture of F16 or 22.
I thin the best way to figure this out topside, is to go out in the later evening, using a flash in Manual. And take some pics messing around. Try shooting up towards the sky and shooting something close. I took shots of the gutters in my house (exciting I know). Mess with the different settings I metioned above and see what happens. I more of a learn by doing.
Hope this helps.

FYI: These are my suggestions. Many photographers have the own preferences. I do feel that the Apeture settings I mentioned are pretty standard starting point. Even the pros don't always agree. If you read Martin Edges book and then Jack and Sue Drafahl's book "Master Guide for Underwater Photographer" you'll see 2 different preference in their shooting modes.
