5D Mark III - Underexposed images

I just got a new 5D Mark III, and it seems to be underexposing images by about a full stop. I've tried all the metering modes, and it doesn't seem to change anything. Anyone else having this problem?

 

Thanks,

Jm

Thank you for the information, Mike. All is good now. The problem existed in the space behind the camera.
Be proud of your work and you will always find someone who appreciates it more than you do.

Hi ReviewFever,

you have set yourself not the easiest task, but if you persist you will get amizing results with this camera. As said by Canon in the previous answer, you cannot just copy exposure settings, as a minimul change in the light conditions, even by the change of the moon will change the outcome.

 

Here are some things you could do:

1) start taking pictures in Raw rather than Jpeg and correct the exposure in the Canon Raw or Adobe DPP. You will have much more room to change the exposure and whitebalance after you have taken the picture.

2) Set your LCD display to show the histogram when you review your picture

3) In manual mode, and with the shutter half pressed, observe the exposure meter, it should be near the middle, otherwize correct your ISO or shutter speed

4) take a test picture and look at the histogram. The basic message is that the higher your exposure (the more to the right the graph is) the least digital noise you will have. However, you dont want the graph to touch the right side of the histogram, because than you will be overexposing. You can easilly move the exposure down in post processing, but if you correct the exposure from low exposure to higher in post processing, you will introduce more digital noise.

5) if your exposure was not giving you a histogram with at least part of the graph in the 5th right most segment, you want to turn up the exposure by taking either a longer shutter speed or a higher ISO. If your histogram touches the right side, you want to move the exposure in the other direction

6) No take the actual photo using the settings you just dermined. Always check the histogram, retake the picture if it was not complying to the rules given in the previous point.

 

Will you let us know if this works for you?

 

Good luck, Pieter

I had an issue as well - except my new Mk iii was over exposing every image. Ran tests with like settings, and was consistently getting better color/images (other than sharpness) with my 7D/Tamron 18-270 than with the Mk iii and 300mmL! Wasn't pleased!!!  Found this site and tried the reset. It appears to have fixed the problem for me. Thanks!
