To each his/her own. Whether you choose to do this challenge publicly in a forum like this, in your camera club, or on your own, I think you will find it useful in improving your field- craft, regardless of whether or not you do this all of the time. I have read many professional and successful wildlife photographer's blogs where they claim they do very little (and in some cases no) post processing of their images. Others choose to do major work on their images. Often times, while out in the field I will set my camera at single shot even though I can shoot up to 200 frames per second. Its kind of like an old school hunter who loads only one round into the chamber. You get one shot. The same goes for your internal camera settings. Its amazing how this challenge, discipline, and practice has improved my wildlife photography when I do use all of the "tools" available on my mirrorless camera. Don't be deterred by the naysayers. After all, isn't seeing improvement much of the journey here?
