Red color cast with Canon 300D
Hi,
On november 7th 2003 I purchased the Canon EOS 300D and it's been functioning perfectly up until about a month ago. I use the camera mainly for shoots in a studio with the white balance set to flash mode. Up until a month ago white has been white, but now (with the same settings) white background shows a very distinct red color cast. The RGB reading in the jpeg is e.g. 249R - 229G - 218 B. Also midtones give similar problem with the same white background: 198R - 165G - 150B. I've been using the manual white balance since a few weeks now, and this works fine. But this is a workaround and not a year has passed since I bought the camera, so I could return the camera for a free repair. The issue with this is that I don't want to bring the camera to repairs, wait for a month and then be told that it's a problem that I could have fixed myself, or that it is not a problem of the camera. I've tried different flash units and different lenses, all with the same result (red color cast). So apparently the problem is not with the light source or lense. Also I use the same background as ever, so the background cannot be the problem. I also tested another white balance setting by photographing the same white background at a clouded sky lighting and the corresponding white balance setting, and with this setting and this light I do not have the problem: I get readings like 235R - 235G - 235B, 227R - 227G - 227B, 184R - 184G - 184B, 162R - 161G - 166B, quite accurate greyscales mostly. So the problem is narrowed down to the flash white balance setting. Does anyone recognize this problem? Should I let the camera be repaired, should I run more tests, can I solve the problem myself without a workaround? Also, I'm wondering if I should go through the pain of missing my camera quite some time to have it repaired if the workaround I'm using in the studio with the manual setting is working alright. I only want to go through this pain when the problem will get worse and it will spread to other white balance settings (if so, I have a problem since only one manual white balance setting can be stored and I don't want to set the white balance manually everytime I take a picture in a different lighting situation). But if I want the camera repaired, I should do it before november 7th, after that date I'll have to pay for the repairs... Any advice? Thanx, Michiel. |

Have you tried taking the batteries out of the camera and letting it sit for
a while? I doubt that it would help in this case but it's so easy to try. |

What is the "color temperature" of your camera set to?
Have you done a factory reset? |

[he has a problem] Good grief, take the damn camera to the nearest Canon repair place and let them have a look. It almost certainly won't take "a month". Two times for me: in on Monday back by Thursday, even though I was told "two weeks" both times. However, I have Big White Lenses With Red Rings, so maybe I get special handling (even though I am not a CPS member), or maybe the Toronto (Canada) office is particularly competent or something. |

There is no light bulb turned on during the photoshoots. I use Visatec 800B flash units for lighting. |

I don't think that there is a way of reading which color temperature the EOS 300D is set to, or is there? But the camera is set to the standard 'flash' white balance and this worked fine up until a month ago... Have you done a factory reset? I reset the camera to its default settings, but unfortunately this didn't help. |
