Turn flash mode off, and use at least 200 lumen led flash light on top of tank glass. One hand on flash light switch and other on camera, so you don't blind your shrimp. Hahaah. I stop taking of the female because she threw her eggs away, after she wiped her eyes. I saw her actually wiping her eyes .
I actually did try that before, with my 9yrs old holding the light ;-) Thanks a lot for your sharing of experience.
