I don't see a whole bunch to add either. I too fight the fish quickly (often amazed at how strong 5x is) and strive to get the fish out of the the current and into slack water as quickly as possible. Wet hands, barbless hooks, and keeping the fish in the water as long as possible are all things I do too.
However, taking photos is where it gets tricky. I basically never took photos of fish until I started posting on this forum. I know I've got some hero shots in my past - but they were few and far between. The thing is, I love reports that include photos of fish that are handled well. Since I like it so much I assume others do too and I now take photos. Ive gone from not touching the fish much at all to, now, either lifting the fish out of the water and taking a quick shot or holding it in the net longer to get a good shot. I really don't have a technique down yet. For a while I just left them in the net and snapped a shot. Now I'm picking them up for a quick photo op. I used to use my phone - but now I use a so-so camera and have it readily accessible in my pack. I'm contemplating hanging the camera around my neck and tucking it into one of the chest pockets of my shirt, displacing prime fly box real estate. I'll have to try it to see if it speeds up the process. All this is to say what do you do? As photos are a part of the release for probably 60% to 70% of the fish I catch I'd love to see some discussion about how you guys strike a balance between fish handling and photos.
