I use a Samsung S21 Ultra at the moment for my photos. Any modern cell phone can usually provide a pretty good picture. I attach a lens kit and use both the yellow and orange filters at the same time. 3x zoom typically for top-down photos.Any chance you can give us the details of your photography setup? These photos are just stunning. I never can get anything that represents my coral colors this well.

There are some other settings that can be played around with to really get pictures dialed in, but usually, I just use the auto-focus settings. I also take my pictures through a coral viewer and try to avoid any glare from my lights. Light settings - usually turn them up to 100 percent output at times of photos.
