The pictures above show that a shot from a reasonable camera may only need a simple one-click of the
auto-colour balance feature available in many software packages.
Other post-processing in the photos above were identical ie saturation, clarity and sharpening.
Correcing color balance is one of the best post-processing tasks to improve your photos. Your
eyes are more discerning than a camera.
If the software doesn't offer specific, white balance adjustment, you have to use the very general '3 - One
Step Photo fix', shown below.
'One step' alters everything, not just colour balance. That might not be what you want?
Most packages offer colour alteration which is usually reduction of the blue. Sometimes
it's too much red but the fix is quite similar. This approach is shown at the bottom of the page.

For color balance correction in PaintShop Pro there are 3 options.
Choose something which is
unambiguously white, black or grey.
In most photos you can find one of more of these colours. White seems to be the best to use if
it is available. Black is second best.
Grey seems a bit subjective.
Then place the cursor in the left of the colour balance dialogue box pair of pictures. A little colour box will
appear (see picture below).
Move the cursor so that the colour shown in the tiny little lower right hand window is as close as possible to the colour you
In this case I was seeking as close to white as possible on the left picture below and
as close to black as possible on the right picture below.
The more the colour is 'away' from what you are seeking as shown in the little box, the more colour correction
will take place.
You want to find something as close to pure white or as close to pure black as
possible. Eyes are often black in the centre. Most pictures have some white somewhere.
'White' led to colours as I remembered but that is not always the case.
I often try to find and use white for reliability, but black is often the choice.
The picture on the right is only slightly greener than the original, (which was shot on a sunny day in fairly shallow, clear
water, so light and resultant colours were pretty good to start with).
The change using white is very subtle (left picture) but the coral seems to be coming up quite nicely. A bit
more 'coral' pinkish/ brown.
Below, original shot too near the surface in underwater setting mode. Tried the white of the eye but
the black of the eye produced the more realistic colour with less red (right picture).
The fish on the left might look 'prettier' but the picture below which used the black of the pupil a
s the colour reference point reflects more realistic colours
of the Chub.
Below . The original shot with a very basic camera set to auto white balance.
What a shocker. Everything has this blue-green tinge and it all appears to be very flat.
The change is dramatic. The black worked better than the white, although the adjusted
colour is still too blue-grey.
Below is more how it looked. Less blue-green with lots of pale, and some 'bleached',
corals. Nowhere near good enough though.
A more basic colour balance alteration using the software that came with the camera. But, check
the web for free photo editing software first.
Just dial out the blue either against the red and/ or the yellow to get the colours close to how you
remember or want them.
Harder to do using scales but better than not doing anything with the Titan Triggerfish? Is still too much blue but at least he is olive and whitish.
