Is it a good idea for an aspiring photographer to read about the technical stuff in Photography books?
I was just reading about some photographers like Diane Arbus who didn’t even know about stuff like exposure, apeture, and f-stops. Do you think it is a good investment of time for an aspiring photographer to read the technical books on photography? Or do you think it’s better to just get out there and shoot?
I believe your source on Diane Arbus was very misinformed.
A lot of people seem to think that if you "… just get out there and shoot…" you’ll somehow take a good picture. Of course, using this logic, its possible that you’ll take 300 lousy pictures and have no idea why they are lousy pictures. That’s where the "technical" part comes in. (A person once stated in here that if they took 100 pictures and got 1 good one they were happy. Talk about low expectations! I honestly believe you’d get similar results if you just gave the camera to a chimpanzee.)
If you don’t know and understand the exposure triangle of ISO, shutter speed and aperture then how can you control your picture making? Sure, you can set your camera on Program AE and let it make all the decisions about aperture and shutter speed but how does the camera know what effect you are trying to achieve? It doesn’t. It can’t. Cameras are just dumb boxes.
If you don’t understand how aperture and focal length are used to produce either a shallow Depth of Field (DOF) or a deep DOF then how do you isolate your subject from the background? How do you make sure that everything from 3′ in front of the camera to infinity is in focus? (Depth of Field is defined as that area in acceptable focus in front of and behind your subject).
If you don’t understand the role of shutter speed then how do you expect to use it to stop motion or to allow a subject to be slightly blurred to show motion?
If you don’t know how the ISO you choose affects both the aperture and shutter speed and the picture quality then how will you know what ISO to use on a sunny day? For sports/action? For the best possible picture quality?
Without a good technical knowledge of photography, how will you know what to do when confronted with scenes that aren’t average and that will cause your in-camera meter to give you a bad exposure? Suppose you have a subject against a bright background and don’t want a silhouette? What if the subject is frontlit against a dark background? If you depend on your camera you’ll be disappointed. Your subject will not be correctly exposed. Suppose your scene is white sand or snow. Let the camera’s meter decide and your white sand or snow will turn out gray.
You also must know and understand the "Rules of Composition". By knowing them you make your pictures more interesting. You know to not center your subject. You know to keep empty space to a minimum. You know to check the background so you can eliminate trees "growing" from someone’s head. You know how to eliminate ot at least minimize a distracting background. Of course, knowing the "Rules" then allows you to break them when your creative impulses overrule them.
So yes, having the technical knowledge is needed. Without it you are just a snapshooter. Point. Shoot. Hope. With it you are on your way to being a photographer. Compose. Shoot. Know.
For the record, I almost always shoot in Aperture Preferred because I like a lot of DOF and I know that lenses are designed to give their best results at between f5.8 to f11. I watch the shutter speed to make sure it isn’t too slow to hand-hold.
