#2. "RE: "CHIIMP"? Viewing the screen after taking the picture- it's a good idea!" In response to In response to 0
It sounds to me like you are using image review (sounds better than chimping) in a constructive way as a learning tool. I like how you stated you're making certain settings, pre-visualizing the effect, and then evaluating the actual results. I see nothing wrong with this approach. As you gain experience and understanding of settings, you'll most likely find yourself chimping less.
I watch a lot of photography related instructional videos on the internet, much of it by recognized and accomplished pros and instructors. They each promote or utilize ways of working that get results for them. Some always use light meters, some never use them. Some look at histograms, some don't. An awful lot of them do review their images on the camera or on a tethered monitor to evaluate their results and make adjustments.
In the days of film only, what did many studio photographers do? They snapped Polaroids to evaluate their lighting setups and make adjustments before taking the critical shots. Taking those polaroids is really a form of chimping, isn't it? As for chimping consuming battery life, just carry a spare.
If chimping is helping you learn and improve your skills, have at it.
