For bouldering, sport climbing, trad climbing, and mountaineering, the composition of your image will make or break the impact of your image. Follow the rule of thirds for your image framing. The subject should be in the upper third of the image for a portrait orientation image and the subject should be in the right or left third of the image in the landscape orientation. This way, you get a maximum amount of exposure from the climb you are capturing and showcase the space below the subject. Play with the placement of the subject in the frame, and in the third and play with the zoom of your lens to allow for the most drama while maintaining some sort of connection to the subject.
