Hi, i just came back from Perhentian with a bunch of underwater pics with a greenish/blueish pictures too. But using the auto-colour correction in Photoshop elements, i managed to correct 95 percent of my pictures. Perhaps you will like to try?

auto-colour only improves the red, blue and green balance IF and ONLY IF there's red to start off with.

Without any reds, no matter how to auto colour, it will always be bluish green.

in your case, you either used the internal strobes or had very good sun or were at shallow water, hence you had some red which photoshop was able to use to auto color. in Blu's photo, there wasn't an ounce of red in the pic at all, hence auto-anything will not work.if you open is photo in photoshop, and look at the red channel, its all black - meaning nothing there.

the reason is mostly due to:
1) if you are shallow, the camera sense that there is enough light and the flash does not fire.
2) Or the distance to the subject is to far that the flash cannot reach.

Thanks..Think Blu knows what happend...Since bro was using the camera for the first time, he could have focus beyond the strobe's range. Also the WB was not set. (most likely he left it at AUTO) Blu noticed that the T30 do not have a WB calbration setting, hence there is no way one can point to something white and inform the camera that is white. Also the camera have not RAW mode, it all JPEG. So blu can't tweak anything either.

So for the moment, blu will just increase the red and decreese the blue in the color settings in Paint Shop Pro..and pray for the best.

Thanks to all who replied, looks like blu gotta bring the camera on a dive to really experience the pro and con of this T-30 and then teach lil'bro how to use the camera....

Anywhere for a cheap Scuba lessons?

Thanks one again. Blu used PS Auto correct and here is the results...

Does your camera have a custom white balance function? If it does, you can already tackle the problem at the source. Just bring a white slate down with you & do a Custom Balance every time you move up or down 1 metre to adjust the spectrum of colours on your digital camera. It basically tells the camera the 'white colour' at that depth & it will automate all other colours accordingly. Strobe function has to be disabled when you do a manual white balance.
