Do you have any tips for how to take sharp photos of fish in the tank? I have a freshwater tank that's quite easy to take photos of, at night. But the fish always comes out looking blurry and dull in my closeup photos . I use the camera in my samsung s7. I also have a dslr but I hardly use it anymore. Maybe I should try closeup photos with that? Thanks. P.s. I see some amazing photos on this forum, like this one for example: Show Me Your Betta And I'll Draw It For You! It made me wonder how everybody else manages to take good photos.
