Help with Pixelation

I read, re read and read again, it seems the more I read the more confused I get, That one page you sent me awhile ago had some settings, I set the camera to the same and the pic's were all distorted, since then I've been pushing buttons, turning dials, and can seem to get a crisp picture. I just reset to factory setting and took a couple of pics, I didn't do anything to them just uploaded to photobucket.

Yeah, manual mode is the best mode by far for fish pics. It looks as though you are shaking a bit when you take the pics. Are you holding the lens right against the glass?

There is also a little dial right next to the viewfinder (eyepiece?) That is a fine tuning adjustment. But if that is set to the max setting one way or the other the camera will never focus properly. Maybe you can try playing with that?

I'm using a tripod, here is some pic's in full auto, the problem here is I can't turn the flash off, I put my hand over the flash to block it.

You can use Custom WB, take a picture of something white in the tank (sand, piece of PVC) and use that picture to set the white balance.

Please post what are your speed and aperture when getting those pictures. What type of camera do you use?

While tripod is really a must when taking such photos, don't underestimate the vibrations that happen from mere pressing the button, specially with a flimsy tripod.

Most of the blurs on your pics, that I have seen, are probably caused by overexposure, and few of them have very narrow depth of field. Many of the shots have very bad light quality, so I advise you to check the histogram.

When taking slow shots (longer then 1/200), as you seem to be, it helps a lotif you turn off your water movement.

Are you using autofocus? Try focusing manually, with several shots of the same area with slightly changed distances, so that you cover the optimal range. Very few cameras these days have really good manual focuser, and autofocus should be avodied by all means as a primary focusre and used only as checking mechanism.

If you are using any of the more advanced digital cameras, what did you set your ISO to? Set it to 800 at very least. There is also an issue wether your lighting spectrum is optiml for that particular camera's sensor. Remeber, they make cameras to repond to mostly different spectrum of lights that we use for our tanks.

Thanks Jack,
I still have a lot to figure out, I took them in Man mode but with auto focus, I can't seem to figure out how to play with the speeds and all the other settings. When I start to change settings I can never get a good shot and wind up having to reset the camera. It's just too confusing for me.
