What mode can you set light/sun levels with w/Digital Rebel?

[JasonMX]

I have been having some nature shots come out darker then they should, because of low light. What mode allows you to adjust the balance for different light levels?

[commando]

I use the exposure lock - the * button. If it's still dark you probably need to use a longer exposure time.

[JasonMX]

Yeah, it's not horribly dark or noticeable but I still would like them a little lighter. I will check in the book about exposure levels.

[commando]

What mode are you shooting in (Av, manual, scene, etc)? Jpg or raw?

[JasonMX]

I am in AV mode where I control the apeture.

[commando]

The camera should be exposing it properly. Try pointing the centre of the viewfinder at what you want to be properly exposed, hit the * button, recompose, and take your shot. Let us know how that goes.

If your shots are a bit underexposed try setting exposure compensation up a bit. Its in the manual.

For the most part just about all of your Drebel images will probably come out darker than they would if they were taken on film. You'll need to do photo editing of all your images. That's what I do. If you want images that come out good without editing I hear the 20D does a lot better with images coming out how they should look without editing.

Whether you are shooting a very dark object or very bright object camera would set the exposure so that the object appears gray. Most of the time you don’t want your object appear gray unless it is really gray. And camera’s metering system has no idea what is the real brightness of your object.

In Av mode camera is using partial metering mode, when only central part of the frame is used for metering. I believe you have several options.

Option 1:Exposure lock *, as was advised above. But there is one very important consideration. The object you are chousing for exposure locking does not have to be the most important object. It does not even have to be part of the frame. It just has to be in the same lighting condition as the frame you intend to capture. And the most important it should be low contrast object, not too dark, not too bright.
Option 2: Exposure compensation. Take a shot, look at the histogram and then adjust exposure compensation. Of course, the exposure compensation is only valid, while you are shooting the same scene. When you move to shoot a different scene, you might have to find different setting for your exposure compensation.
Option 3: Exposure Bracketing. Choose the exposure bracketing range from the menu. On each scene fire 3 shots. Those three shots would have different exposures. Then you can choose the best one.
