There are 5 key settings which can make you a Much Better Photographer
Why Are You Still Shooting in Auto Mode? _______________Go Manual Mode
If you're one of those, and admit it if you are, who just want to get the shot and share it, fine. Just keep using that auto mode and sharing to your heart's delight. It's fast and a lot of fun to toss those cute shots up on all the most popular social sites we all know so well. Everybody does it. And there is nothing wrong with it and no reason to stop. Or is there?
If there's nagging little niggle in the back of your head that
keeps tugging at a desire to get on track to better shots,
remember the five adjustments you need to become familiar with. And we begin this discussion with your camera in the Manual Mode. As we go through these know that when adjusting one of these, Exposure, Aperture and Shutter Speed it automatically adjusts another.
White Balance + ISO + Exposure + Aperture + Shutter Speed
White Balance
White balance enables your camera to capture colors in a given light atmosphere. What you want to happen, unless you are attempting a creative effect, is to properly asses the light correctly. This way whites are true whites, colors are true to their spectrum. While cameras today, if left on auto white balance perform a very good interpretation of balancing the white or near white areas in a composure, you can do a better job (all things being equal), by looking at the light and the white, and setting the white balance to different Kelvin scales by simply choosing from the following; Sun, Shade, Cloud, Incandescent/tungsten, Fluorescent, Flash (or Custom White Balance if your camera offers this last option. this way you have now become the judge for lighting. If you choose in the settings menu, Tungsten for example, because you are indoors and the bulbs are the old style incandescent, you have more information now than your camera does. you know for a fact that it needs to expose for that type of bulb. Similarly if you are out in the sun, you can choose sun, shade, Shade and so on. Or you can go to Custom White Balance, you would take a picture of the brightest subject in your frame, then go to Custom WB and click on the picture OK. Then you would want to go to the white balance button, here I am referring to Canon upper end bodies though you'll need to refer to your manual, and press the white balance button and move to the tungsten bulb icon, then recompose and take the picture. Or you can set the Kelvin at a particular number. Below (1) you can see the Kelvin numbers as they relate to varying sources of light, so you can attempt even more accurate white balance settings.

5,500–10,500 K | LCD or CRT screen | ||||||||||||||
15,000–27,000 K | Clear blue poleward sky | ||||||||||||||
These temperatures are merely characteristic; considerable variation may be present. |
As you can see by the colors and corresponding numbers they line up with different light sources which you can select from by merely adjusting the Kelvin scale value up or down according to the type of lighting you are in at the time of exposure. This is the most accurate way to capture white balance, but you must be spot on in your number selection, or your colors and your whites in the subject of your viewfinder will not accurately be displayed when shot.
ISO for Digital like ASA for Film_________________________
ISO is the sensitivity of camera's your sensor to gather light and properly expose a shot. At a low ISO setting say 100, your camera will do its best work in gathering the appropriate light for a good shot. You can adjust this up or down as needed. Say you are in a bright sunny location as is your subject. ISO 100 is the superior setting. But let's say you find yourself in a sunny exposure but your subject is not. You might be better off trying a shot at 100, then 200, then even 300 ISO and compare the outcome. Or perhaps you are inside and the ambient light, or existing light without the aid of a flash, is simply insufficient and cause your lens to stay open longer, resulting in perhaps a blurry photo or a darker photo. Here is where you can dial in a best ISO setting. In some cases you'll have to reach up to 800, 1200, 1400, 1800 maybe even higher. However you must remember that by reaching up so high you are introducing so much more sensitivity into your sensor that it is forced to introduce more light matter that it shows up in what is called NOISE. That's nothing short of ugly. When you crop to 100% or more, and cropping is advisable to see what your image looks like when printed, you'll be disappointed. So be careful when pushing the ISO, but in some cases where introducing a flash or speedlite is not allowed, you may be forced to do just that. The end result is if you insist on taking pictures where the ISO is extremely high, your ability to print is replaced by presenting the pics online and small. On the other hand when you can select a setting of the lowest ISO necessary, you'll be able to improve on the camera's auto setting, though I'll admit, cameras today are really quite good at automatically grabbing the proper ISO. So experiment and see what you can come up with. This is the fun of playing with your camera settings.
Exposure______________________________________________
The idea behind exposure is to balance the available amount of light. for a good, well, exposure. It is an adjustable feature that allows for decreasing or increasing the amount of light using a wheel or a button, so that you don't find your captures over or underexposed, meaning too bright or too dark. Again while the auto setting does a darn good job, this can provide you with the tools to create more light when there is not enough available, or less light when your other settings are gathering more than you desire. When shooting you should see in the viewfinder, assuming you have one, where the needle is, digitally. Merely move the exposure setting to where your capture is turning out that perfect image. And you can, if your camera offers this option, check for Highlight alert in your Histogram
