When we go outside it is usually just two of us. One climbs and another belays or spots the climber. No one can operate a photo camera. But we found a solution to have at least some photo material. We record 4K videos with a video camera and later on take an interesting frame. 4K video has enough resolution to get decent quality photo for Instagram.
Here are few examples made with Sony FDR-AX100 camcorder.
