1 Wa­ter colours

White bal­ance can be off un­der­wa­ter, so shoot in RAW. In Adobe Cam­era Raw, grab the White Bal­ance tool and click over a point that should be neu­tral to fix colour casts. Next, open the im­age in Pho­to­shop and tweak the colours with a Color Bal­ance Ad­just­ment Layer.

2 Tidy the back­ground

Pool mark­ings can be dis­tract­ing, so re­move them for a seam­less back­ground. The two tools for the job are the Clone Stamp Tool and Spot Heal­ing Brush. Both can be set to Sam­ple All Lay­ers, so make your ed­its on a new, empty layer to pre­serve the orig­i­nal im­age.

3 Fix chro­matic aber­ra­tion

Us­ing a hous­ing means shoot­ing through ex­tra glass or plas­tic, so you might find colour fring­ing af­fects edge de­tails in your im­age. If this is the case, go to Fil­ter>Lens Cor­rec­tion, then use the Man­ual tab and ex­per­i­ment with the three colour fring­ing slid­ers.
