I picked up this go pro blue water camera filter a while back on a clearance rack and finally tried it tonight. The results impressed me. I'm going to try this out some more this week when only the blue lights are on. Anyone ever used something like this before?View attachment 1326The first photo is without the filter and the second is with it held over the lens of my Galaxy S7.This is the filter: https://shop.gopro.com/accessories-2/blue-water-snorkel-filter-hero5-black/AACDR-001.html
