I have too many pots on the fire. Or as the saying goes: jack of all trades, a master of none. At 75, I stay busy. I'm learning about shooting off auto. Albeit slowllly! I'm wondering why can't I just shoot in auto? Then I'll do all the great for looks on my post processing program( On1Raw)? I have been reading posts here and most everyone seems to shoot off auto. Can I get a great photo after pp that was shot from auto mode? Any suggestions are greatly appreciated.THX!
Are you using "Auto" or are you using "auto"?
What I mean is that to make best use of post-processing, you should be shooting RAW files. Those have a lot more latitude for post-process adjustments.
Most cameras today have an "Auto" mode.... which might be better called "super auto" since it automates far more than just exposure. It also dictates how your autofocus works, whether or not the flash will fire, makes you use Auto White Balance, and even limits what type file you can save.... JPEGS only (in all cameras I'm aware of).
That "super auto" mode is different from "auto exposure". "Super auto" is sort of a "point n shoot" or "camera phone" mode. It's there for folks who can't be bothered to learn how their camera works and have no desire to control it or to do any post processing of their images. (Some cameras also have "scene" modes.... similar to "super auto", but a little more specific.... for sports, portraits, scenic shots, etc. These also automate a lot more than just exposure.)
Your camera also has several "auto exposure" modes: aperture priority (A or Av), shutter priority (S or Tv) and program (P). If it's a fairly recent model it probably has Auto ISO, too, which can be used in conjunction with Manual mode (M) to give you a fourth form of auto exposure.
All these modes can be used to deal with variable lighting conditions or just because you aren't sure yet how to calculate an accurate exposure (AE). Aperture priority lets you select the aperture (and the ISO), so that you can decide if depth of field is going to be shallow or deep... and the camera selects an appropriate shutter speed. In shutter priority mode you select the shutter speed (and the ISO) that will render movement either sharply freezing it with a fast shutter speed or letting it blur a bit with a slower one.... and the camera chooses an appropriate aperture. In program mode you only select the ISO (lower makes for better images, but it needs to be high enough to give adequate shutter speed and/or the size aperture you want to use). Auto ISO with M is a new type of AE.... where you select both the shutter speed and the aperture, but leave it to the camera to choose what ISO to use.
All these modes leave it to you to set the white balance and your auto focus as you see fit.... and they allow you to save either JPEG or RAW files... or both.
You also get Exposure Compensation (E.C.) in these modes... which allows you to override the exposure the camera is choosing, to adjust for unusually light or dark situations. For example, if you are photographing a bride in a white wedding gown in a snow storm, the camera will want to underexpose... so you can dial in some plus E.C. But if you are shooting a black bear in a coal mine, the camera is going to try to overexpose, so some minus E.C. is needed. You can't do any of this "fine tuning on the fly" when using "super auto" mode.
In contrast to all of those, there's also M or manual mode.... where you set everything (no Auto ISO either). It's nice when you can use this because you can lock down your exposures and not have them skewed by the camera's metering system. Some people might try to tell you this is the ONLY mode REAL photographers use... but nothing could be farther from the truth. In fact, there are situations where lighting is variable and you simply can't use M... where you must use one of the AE modes to get a good exposure.
I don't know what camera you are using... but some have built in guides to learn to use the various settings. Many Canon, for example, have a "CA" or "creative auto" mode that gives "wizards" on the rear screen to help with the settings. I bet other manufacturers have similar.
So, which are you using? "Auto" or "auto"? If you are currently using "Auto", I'd suggest you try "P" instead, and set the camera to save RAW for post-processing .... Or set to save RAW + JPEGs if you have plenty of memory cards and hard drive space. This can be helpful when learning to post-process.... giving you both an in-camera "developed" JPEG and a RAW file that you can develop as you wish using the post-processing software.
And with P you can choose to use Auto WB or not (custom WB are most accurate, when you have time to do them and set them correctly)... set auto focus as you see fit... use different metering patterns on many cameras (matrix/evaluative, center-weighted, partial, spot).... take charge of things with Exposure Compenstion... decide whether or not to use flash... and more.
