Auto White Balance Vs. Custom White Balance using a Canon Xt(350D)

[icicle]

Here is my Comparison on white balances
A.
Shot this using an overhead 60 watt house light bulb, Auto White Balance

B.
Shot this using 2- 250 watt Halogen work lights cross lit, Also in Auto White Balance.

C.
This is a piece of white paper being held upright by foam board, that I used for my white card.
Also shot cross lighted with 2- 250 watt Halogen work lights. Auto White Balance

D. This is a piece of white paper being held upright by foam board, that I used for my white card.
Also shot cross lighted with 2- 250 watt Halogen work lights. Custom White Balance
And the Exposure was set +1 1/3, neutral exposure was too dark.

E.
Shot this using 2- 250 watt Halogen work lights cross lit, Custom White Balance

F.
Shot this using an overhead 60 watt house light bulb, Also in Custom White Balance


Also to note that these were Shot using Av Priority with F/4.5 ISO-100 I also shot these in Adobe RGB
Please do not Correct these pictures, Only post processing was done was to re-size them.

Good example. Are you shooting JPEG or RAW?

Jpeg. If I have something very important to shoot then I will shoot in RAW

So I would be safe to say this is not going to help much then.

Please do not edit this one either

The reason I asked was if you shoot RAW, you can easily adjust white balance after the fact. If you're shooting in a controlled environment, then I think a custom white balance is useful. Otherwise I would just use auto white balance and shoot RAW.

I've had enough experiences where I thought I was doing something unimportant but later decided it was very important. now I shoot maximum resolution and RAW all the time. It's just not worth it to me to risk JPG. If the color is off, they're way too hard to fix. If my exposure isn't right on, they're way too hard to adjust. And I rely on the extra dynamic range in my RAW files so that I can get what I want in post processing.

Call me a dinosaur, but I always shoot raw and almost always set a custom white balance. While raw is easier to work with and make adjustments, when shooting in low light a dead on exposure will have less noise at any given ISO than one that is not dead on. At high ISO it can be noticeable.

I also always use a custom white balance product, not a piece of paper. Paper, even "white" paper is rarely truly white.

Just had to give up some of that old film days training. It still fits in the digital age.
