The histogram of my pictures usually falls within the first 3 quarters. I understand that rightmost quarter stores more information about the picture followed by second right quarter and so on.
I have played with several settings of my Nikon D70 camera and have tried changing the aperture, exposure settings (increasing the exposure by several steps) etc. but still I'm unable to get my Histogram move towards the right. I change it in Photoshop using Levels but I'm wondering if anyone can help answer my question.
Thanks. Michelle

The mode you're shooting in and the type of exposure metering you're using are both very important. In full auto, Av or Tv modes, the camera will adjust parameters to put midtones in the center of the histogram. This may or may not be optimal.
Try putting the camera in manual mode. Set up to shoot a test scene. Use a tripod so you're always shooting the same scene, and try to shoot under light conditions that aren't changing. Now change aperture or shutter speed, and you should see the changes reflected in the histogram.
In Av or Tv modes, you'll need to set exposure compensation upward to get the camera to compensate. |

Depends on you subjects, background, color, etc. If you have dark colored objects the histogram will be mostly to the left.
Post some pictures.

| I actually have noticed a similar situation on my D70s. Even with +1 EV exposure my histogram usually is heavy to the left - even when shooting mainly white / light settings (ballet dancers in a white room). I'll switch the display to show me blown highlights and have stuff flashing but STILL there's hardly any info on the right. I was thinking it's just me, but maybe not... |

Probably not. If you're using multi-point metering, the camera is probably going to try to avoid blowing those areas out, and thus you get a shadow-heavy histogram. Which is not a bad thing, if youreally did want to avoid blowing those spots, but not a good thing if you did mean to blow them.
Try setting for center-weighted or spot metering, zero exposure compensation, and manually meter on something that should be mid-gray. Now you should get exactly what you expect. |
