EOS 5D Mark III Images too dark in Tv and Av but OK in M

[Chrisc99]

Hi, I shoot with a Canon 5D mkiii in manual and the lighting is fine, recently I tried to shoot in TV and AV but the images kept coming out dark even when I upped the ISO.

Does anyone have an idea of what could be wrong ?

Thanks Chris

Are you sure you don’t have Exposure Compensation (EC) dialed in on Av or Tv modes if so set it to 0. Are you using a flash or not? If so remove it for testing and make sure Flash Exposure Compensation (FEC) is set to 0.

How would i check and where would i find EC please ? and no i wasn't using a flash.

@Chrisc99 In Av & Tv Modes what would be the light meter is now the scale for Exposure Compensation (EC). It can be accessed from the LCD screen. The area highlighted in the picture is where you need to adjust it. If not already set to 0. It should be set at 0 for the correct exposure. Unless you want to add or subtract Exposure Compensation (0).

Looking at the LCD was all the way across to -4 having changed it to 0 it has worked.

Thank you
