No matter what I try, I can't get a white background to look white in my photobox. If I use a black background, it's fine. I've tried everything I can think of, even including to read the instructions in my camera manual and to buy 10% digital photocards and nothing works. I'm currently trying 40w Reveal incandescent bulbs (one on each side, one on the top) and I've also tried florescent bulbs with the same results. I've tried every WB setting on my camera and the best I get is tungsten, although it looks dingy and a little low light-ish. I've used several different ISO settings as well.
I have a Canon Powershot point and shoot but that really shouldn't make all that much difference. My wife has a very nice SLRS that I can use, but I don't want to give up trying to find the answer to my problem with the background. I also have a tripod at the ready but that won't have anything to do with the background.
Help (KIS, please)!
Denny

Were you able to go through the setting custom white-balance procedure?

Keep in mind that the correct white balance will not add light. If your white is still gray, you'll need to adjust your f-stop/exposure. Try bumping up your settings. My cannon has -2 through +2. Try those before you give up on white balance.

+1 for rockjunquieBlack blacks are attainable by correct exposure and ANY under exposure. If your camera is underexposing all images by say 0.5-1 stop, then black is black but white is never white. sheltie - can you adjust for exposure as Tela describes? If so, try an experiment. Take pictures at 0, +0.5, +1, +1.5 and compare. Take the pics with background 50/50 black/white and a bag of skittles. |

Denny, I completely understand your frustration. You are not alone in this. I don't know anyone who hasn't struggled with photos. You just have to keep at it. It took me years to be able to get decent pictures and I still have numerous bad picture days. I still experiment, too. Scott's right. Just keep trying different things and make notes.

Try those before you give up on white balance. By f-stop exposure, are you referring to the ISO settings (auto, 80, 100, 200, 400, etc)? I can't find any other place for f-stop. I know they used to be on a knob that you twist, but not on this one. I'll recheck the manual by don't remember reading about it. I just read Scott's post above with the libnk so I will now look for the EV. For Daniel, sometimes the flash is on, other times no. I'll turn it off. |

Daniel, from what I am reading I am certain his camera is underexposing every image.
Every digital camera I own has done that. Androids worst than Nikons. My Canon EOS 550D is under by 1/3 against a professional light meter sold in the days of film cameras. I am OK with 1/3 in that camera.

Argh! Nothing about EV either in the Table of Contents or the index. What else should I look for? Is it ISO?

I think I found it, called Exposure Mode and it allows me to go up or down +/- 2. I'll give it a try and let you know.

BINGO! I set the setting at +2. Now I have to work on getting the colors right. The color is this picture is just slightly off. How do I do that?  |

I recently bought a Canon Powershot 280HS. WB is fine.
Your striped rock photo looks like you went a bit too far. I correct or up the white in Photoshop Elements using Levels and the white eye dropper.

Yes! Success
+2? Really?
That is letting in 4x the light from before.
Color is/can be fixed in photoshop or GIMP

maybe try +1 and get brighter than 40 watt. you are a little overexposed.
otherwise correct color in photoshop. also best to use gray background. with enough gray even auto-color in photoshop works pretty good.

I'll lower it to +1 later and try again. It's nice to know that at least I'm getting there.

While looking at your stone through the camera screen, check out all the WB settings.
Turn off all other lights in the room except the one or two used for taking photos.
Use daylight lamps and use filters over them. I use vellum sheets for filters; they don't create wrinkles which show up as shadows.

+1 to darkened room. Also minimizes reflection of photographer on very shiny objects.

Don't forget not to wear bright clothing- sometimes the stones and/or metal can pick up the color cast.
