Here is my checklist:
-Turn all the flow off
-Turn lights all the way up (whether it is blue only or a mix)
-Use photobox/portal (instantly improves your photo taking ability)
-WRAP THE CAMERA STRAP AROUND YOUR NECK!!!
-Set camera to RAW
-Turn camera on manual (just starting this myself)
-The reason you turn your lights up is so you can turn your ISO down, faster shutter speed, and f-stop around 11 or 13
-Brace against frame of tank or center brace
-Regret having just had a pot of coffee
-Take the photo
-Adjust, Try again, Take the photo (x10)
-Edit in Lightroom (Temp and exposure only)
