Step 4
Create a Color Balance adjustment layer to make the fish's color fit the background.
Step 5
Make a new layer, change the mode to Overlay 100%, and fill with 50% gray.
Activate the Dodge and Burn Tool (O) with Midtones Range, Exposure about 10-20% to refine some light and shadow on the fish. You can see how I did it with Normal mode and the result with Overlay mode.
3. How to Make the Frozen Effect
Step 1
Place ice texture 1 over the fish and change this layer mode to Soft Light 100%.
Use a layer mask to remove the part outside the fish.
Step 2
Add a Hue/Saturation adjustment layer to desaturate the effect's color.
Step 3
Use a Curves adjustment layer to increase the contrast of the effect.
Step 4
Add ice texture 2 using the same method.
Step 5
Place ice texture 3 onto the fish and change the mode to Overlay 100%. Apply a layer mask to clean any unwanted parts outside the fish.
