Setting white balance

I set my white balance but I have a quick question. I was shooting a piece of white paper in my room, where light is ok but nothing great for a camera. Exposure was right, but the paper almost seems a little red in the pic. Will this be ok ?

Can you post the pic?

No..... Of course, one second.

I should of said more brown

???? Going out tonight, figure I'll just retake the pic out in my garage. Shouldn't matter that there is fluorescent light in there should it ?

Open that picture in Photoshop, go to Curves, select Gray Point picker.
Click on the image, click OK and it will become (about) 18% gray.

But how would I get it back on my camera ?

The EXIF indicates that auto WB was used. Is this what you set your camera to? AWB doesn't work terribly well with non-natural light in my experience.

If you are trying to use the shot of the paper to set Custom WB, then yes it will matter if you change the lighting.

You could use the picture of the piece of paper to set CWB then if you shoot a picture of the piece of paper again it should come out white (well gray if you used it for metering as well). Now if you leave this set for CWB and go out into the garage (assuming it has different lighting) then your pictures are going to have a colour cast again.

Yes, followed the instructions in the booklet. So whats the best way of going about this ? I thought about taking a picture of the paper again with WB set, wondering if it would come out grey or white, or I should say whiter then that pic I posted

If you want to use the same image to set Custom White Balance on your camera, press WB button, select Custom, press SET button.
Click on <> key to select your image, click SET.

Hmm..
It’s kinda complicated to write in detalils, with all that icons.
Why don't you read page 57, Instruction Manual.

If you don't have it at hand, you can download it from here:

Shooting indoors I would suggest using CWB if you have the time or if not use a specific WB setting like Tungsten or fluorescent depending on the lighting.

Since you have the shot of the white piece of paper already, you can just use CWB. If you are shooting RAW you can correct in conversion as long as you have a picture of your gray/white card (or there is something in the picture itself you can use).

I read it, but I don't think it said anything about what you said to do in photoshop.

Photoshop has nothing to do with custom white balance in the camera. To set a CWB, you take a photo of the paper in AWB. Then you go to the menu and find "Set Custom White Balance" It prompts you to select a photo on your card/in your camera. Select the photo of the paper you just took. THEN you need to go to your menu, and actually SET your white balance to Custom. NOT Auto. If you leave the white balance in AUTO, then you're ignoring the paper reference altogether.

I know that, but the guy up above said to use photoshop.

"Open that picture in Photoshop, go to Curves, select Gray Point picker.

I set the WB and know how to pick it, I was just asking if that color being to light cause it was shot in my room will effect anything

That's a white piece of paper. If you set custom white balance properly, take a photo of it again will render it white. If that's how it looks either in AUTO WB or by improperly setting a CWB, everything you photograph under those lights will have that color cast.

Whether that's ok with you is entirely up to you. It's technically wrong.
