How to photo edit underwater pictures - the basics

2 - Correcting Color Balance

this removes some of the dominant blue so reds and yellows are back in balance - the scene is more as you remember

With a good compact, one click autofix can be the simple solution

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.

For color balance correction in PaintShop Pro there are 3 options.

Choose something which is unambiguously white, black or grey.

zoom a bit and pan to object
Choose your object by zooming in a bit (x20).   Then pan/ move - the image in the right hand box so the object you want to use, in this case the eye, is dead centre of the right-hand box.
zoomed object
Then, zoom right in.
Here, zoomed to 200 (ie just added a 0 to the 20 already in the 'zoom' box - lower left).

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 want.

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.

choose black

Some other examples

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).

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.

No PaintShop Pro but software with a colour balance wheel or scale!!

Orginal below totally dominated by blue.

A more basic colour balance alteration using the software that came with the camera.   But, check the web for free photo editing software first.
Software scales shown below.

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.
