COLOR CORRECTION FILTER

There are varying opinions on the effectiveness and/or need for this device. This color corrective filter threads onto the front of the housing for taking underwater pictures at depth without the flash.
This filter came with a clear plastic soft case. I doubt that will protect it from scratching or breaking.  Hence the need for a hard case. This is a Max Factor makeup case. Scrape out all the makeup and the aluminum insert, then drill some holes in it so pressure won't build up from your descent. Only the lens rim makes contact with the case. It fits easily into your BCD pocket. You can soak the lens in this case alongside the camera after diving.
