i have a canon a590 is.it was bought pretty much as a family camera that we could carry around.i chose this one for the price range and still seemed to have some manual controls.does anyone have one and have any quality pics i could see for inspiration?also is anyone familiar with this camera and could tell me if i might be able to get some decent tank pictures with it.

Av? Yes
Tv? Yes
RAW? No (aww)
No matter, every tank and lighting setup and show room will require differant settings. I suggest turning to Av and selecting the lowest number it will go to though. Hint: You can get a lower number if you zoom out (wide) instead of in (telephoto)
This will help freeze any fast moving objects in place and/or blur from your hands.

Read about Aperture, Shutter Speed, and ISO. You should also figure out the "crop factor" your image sensor produces. I would imagine it is somewhere in the neighborhood of 5x (educated guess). So take the focal length (mm) your lens and multiply it by 5. Make sure your shutter speed matches or exceeds this number. i.e. lens @ 10mm, shutter speed 1/50, 1/60, or 1/125 would be even better. 1/20 will probably give you a blurry mess.
I've got the same camera. When you use Tv mode, the camera is limited in the size of aperture it can choose (by the physical camera design). If the shutter speed is too fast, there will be no aperture setting available to allow an appropriate exposure. Instead, the aperture value shown on the LCD screen will flash in red. Is that happening in your case? You could bump up the ISO but going over 400 (at most) will introduce noise.
The Av choice is more foolproof - whatever aperture you choose, there is nearly always some shutter speed which will provide a good exposure. Also, Av gives you more direct control over depth of field (more relevant for dSLRs).
The photos you posted look nice (especially #1). Are you using a tripod?

no i did not use a tripod.i did do some work on the pics in photoshop.i dont know much about photoshop either.i tried to mess around till i got them looking as close to what i see with my eye as possible.i didnt wanna enhance the photos beyond what thay look like in person,but wanted to get them as close to that as possible.do you have any pics i could see that were taken with your a590?also are you happy with it for reef pics?i may later get the g10 but didnt have the funds at the moment and got a really good deal on the a590
I got the A590 for general travel photos, etc. I've tried a few reef pictures but nothing that is worth posting. I'm in the process of upgrading to a dSLR (Nikon D90) which should be more suitable for reef and macro photos. That said, I like everything about the A590 except: slow flash re-cycle and the tiny view-finder. It took very nice outdoor photos, including some macro-type photos.

I agree with the statement below that the camera is likely being pushed beyond its aperture limits. When you zoom out (i.e. 6mm) you can use an aperture of f/2.6 and get more light in there. To zoom in farther (i.e. 23mm) you will need MUCH more light to achieve an acceptable exposure in the eyes of the camera's metering system. If your aperture symbol is flashing as stated previously, turning up the ISO should help. Unfortunately when the images are too dark, you have surpassed the brink of what the camera is physically capable of with the selected settings. Using a tripod will allow you to safely use lower shutter speeds (and therefor smaller apertures), increasing the cameras capabilities in the eyes of physics. As you can see your "mini tripod" has substantially improved the camera's capability. A half way decent tripod will allow you to take pictures simply impossible without it. I recommend you use "Av" as opposed to "Tv", especially with a tripod.
