In reply to beneboy: Thanks , clothing is certainly part of the equation to make the climber stand out from the surroundings and sometimes if I'm doing a shoot with mates they'll have a few different colours of tops to change between locations depending on the surroundings . Using the best lens you can afford to kkep the image as sharp as possible , i use the centre focus point only most of the time as its the most sensitive . Body position , making sure the limbs dont lead out of the frame and some dynamic movemnt also helps rather than just standing but thats also not always possible. Climbers are often looking down at their feet and trying to get a shot with the head up i think makes a big difference . As far as PP goes , 99% LR4 and 1% CS6 to remove little spots etc and sharpen using high pass set around 3.5%and overlay. Hope that helps ?
