Hue-nut has also mentioned more than once he takes most his pics with his iphone. I know from owning one that it only takes a couple seconds to get the camera up and ready, at least you can do the effects later on though
still no idea how he gets the fish to co-operate
I also have the same problem with every fish i catch, the problem of not being able to get them calm while not holding their tail or at least a hand across the belly to calm them. I also think its been a few years since i even got a pic of a wild steelhead because im usually to busy admiring them as i remove the hook and revive and release them to continue their journey
hatchery ones of course are easy to take pictures of because they are stone cold dead !!! LOL
