I took this picture at the conservatory yesterday....what did I do wrong? It was very sunny and I was using a 1X extension tube with my 75-300mm lens. I had the camera set to Program Mode with ISO-200. Any help or suggestions would be greatly appreciated. I have many pictures that turned out like this.

my extension tubes don't allow for data to be passed to the camera from the lens - I have to shoot manual
if yours is like that too, then your camera shot with no information for the exposure, and you over exposed.
I meter the shot with the camera and the lens, put the extension tube in, then set the camera to manual and to the settings that I metered.
Then I use curves on the back of my camera to watch the exposure and tweak it.
Hope that helps.

to me, it just looks way overexposed. you said it was sunny and your shutter speed says 1/80. To me you probably wanted to shoot at more like 1/500 or 1/750 or faster. All the highlights are blown out which is why it looks so white. If you shot in RAW mode you may be able to recover some of the detail, but in my opinion trying to fix the exposure now will just lead to a over processed image.
In the future when you are in bright light, I would recommend using the lowest ISO possible and shooting in manual mode. use an aperature of 8, 11, or maybe 16 and adjust your shutter speed accordingly. Just check your display to make sure your exposure looks good. |

It does look like metering was not working properly. Which extension tubes do you have? Do they provide electrical contacts? If they do provide contacts, then AF will work (or at least try to) and the aperture will be set properly.
For the Canon system, a proper extension tube will enable all functionality of the lens. If an extension tube that does not allow proper communication is used, then:
- You need to use a lens that allows manual control of aperture
- You need to pre-set the aperture to the value you want to shoot with; that means focusing and metering with the aperture "stopped down."
- Under the above conditions, use either full manual mode, or Av mode. In Av mode, metering works normally, and the shutter speed is set to obtain proper exposure. |

Thank you all for you help. My extension tube does not have contacts. As stated, I should have used the manual mode and set the settings. I was assuming (without really thinking) that the Program mode was going to work. Thank you all for your comments. It is SLOWLY all coming to me...little by little.
