I have another kayak picture. And as advised in a previous thread of mine (forgot whom suggested it). He had changed just the color of the water from its diareah color to a more eye pleasing subtle blue.

Everything I have tried besides going in and selecting the kayak has resulted color shifts in the other colors as well. Is their any easier way then just selecting the kayak-guy? Or will that be the easiest and better choice?

I have the image at a higher resolution. I have not enhanced it in any other way as of yet.

Thank you for any advice.

if you are trying to change the colour of the water to blue & keep everything else I can suggest something i do.
I use PS so these are the steps I use.
First, using the selection tool, select the entire pic & copy it. Then change your colour mode to grayscale to turn the pic b&w. Then change the mode back to rbg. The pic will stay b&w. Now, create a layer & paste the copied original of the pic so you have 2 layers, one b&w & the other the coloured original.
Now comes the hard but fun part. hide your colour layer so you only see the b&w layer. Go to the hue/saturation menu & select a blue that suits what you are looking for. Once you have done this, make sure you reveal all your layers in order of you newly converted b&e layer is on top.
Make sure that you have your top b&w layer selected in your layer window, & click on the vector mask button (looks like a square with a circle in the middle). This will let you reveal the bottom layer using the paint brush.
Be sure to go to the default black & white BG & FG colours & select the paint brush. Black reveals the the bottom layer & white hides it (or vice cersa, i forgot.) Use the paint brush to reveal the bottom original layer on the man on the kayak so when you finish, you can have your blue water & your orginal man in the kayak.
Dunno if this is the best explanation for this but I will give your shot a whirl & post it when I am done.
Good luck & hope this was helpful.

just realised something. skip the step where you change the pic to b&w. just make a dupe layer & mess with the hue to get it to be the blue you want.

Thanks alot rooster. Yeah I was messing with just trying to selet the kayak-guy and it was very time consuming. Also tried 2 layers colorizing one to slight blue and then erasing the guy on it.

Nice explanation. I can do most things but just wondered if they was a better way then I was doing.

Here's a quick pass at it...



I used "select color" on the brown water, then used quick mask mode to touch up a few areas on the water that did not get selected (the highlights mostly).
After making the selection, just channel mixer and curves to adjust the water. I also used the curves adjustment to darken the water generally to make the subject pop a bit more.

Select > Color Range
Adjustment Layer > Hue & Saturation
Adustment Layer > Levels
Copy image layer and set to Screen 34%
Use sponge tool to selectively desaturate bits of waves
