| My flash (Canon 550ex speedlight) is constantly changing. In one photo it will falsh too much and the next shot not enough. It is so random on the way it is flashing. I have done tests with the same flash on other Canon cameras and have not had a problem with it. I talked with Canon support and they said I would be haviung to send my camera in which could take p to 6 weeks. I can't afford to have my camera gone. Anyone with any suggestions on the matter? Has this happened to anyone else with a Canon 10d? Thanks in advance. |

I may be wrong so please take it with a grain of salt. But what this seems like is the camera is flash metering on different spots from shot to shot. This isn't something that needs to be fixed.
For me and my 20D, I center the circle on the spot that I want flash metered and press the * button to pop a flash and thus store the flash exposure reading in memory. Then I recompose the image and take a shot.
If I don't do this, the image may be over / under exposed depending on what is in the circle at the time of exposure.

| I am not sure how to pop the flash like yuou are talking about but I do know that I can have the same shot, same subject, same lighting situation (just taking two or three shots of the same thing) and can get a different look with every photo. The meter is always centered in the middle of the subject. If I am in tungsten light the flash doesn't even componsate for it...they are all yellow. But if I put the same flash on my film Canon camera and take the exact same shot, the colors come out perfect and the flash is great. What am I doing wrong? |

Your hotshoe may be damaged. If the flash is not making good contact on the hotshoe, these problems will happen.
Situation 1: The camera pre-flash will fire and not the main flash, causing your shot to be underexposed.
Situation 2: Your pre-flash will fire and not be able to interpret the metering and the flash will fire at full power, causing the shot to be blown out.
I have had this problem and had to have it repaired.

Popping a flash is, for me, pressing the AE Lock button (the *) when I have a flash attached or using the popup flash. When I press it, it sends a shorter / lower power flash burst and measures the scene, then stores the flash exposure in memory - usable when I take a photo.
