Equipment: Nikon 10.5mm / Inon z240 type4 x2

I guess converting bat fish photos to a monochrome is quite common to show the stripe pattern of bat fish.
Since we can't preview the results of software editing underwater, how do you make sure conversion can be satisfied?
Any ideas to prove my pictures?
