Frustation with Histograms!


Can somebody PLEASE help me figure out histograms? Most of my pictures have clipping on one end or the other, often BOTH ends! So, if a histogram is clipped at both sides how do I fix the problem? What does that mean? I almost NEVER get a perfect histogram no matter how much I mess with my exposure. I'm confused to say the leasst. Pictures that look fine to my eye have very pathetic histograms. Wah! I don't want to depend on my LCD. But I am not understanding histograms.

  A histogram that is clipped on the left is under exposed, and on the right is over exposed. If it's clipping on both ends you've got a dilemma. The only time I can imagine clipping at both ends is if your scene had very bright areas and also extremely dark areas. In other words, the contrast level was far greater than your sensor could handle. Same thing can happen with film, especially slide film, and remember, digital sensors respond to light very similarly to the way slide film does. It has a very small amount of latitude. The only thing you can do here is to favor one of the ends. I would ALWAYS favor the highlights, and let the shadows fall where they may. And whatever you do, DO NOT depend on your LCD panel for exposure.

  Thanks Michael,

I know I shouldn't depend on the LCD. Histograms are being difficult for me! If a histogram shows underexposure I'll try to correct the exposure 1/3 of a stop at a time. But I'm having a hard time. I think maybe I'm taking pictures of things that are simply strange in tonality. Granted, I need a lot of practice. I'm working on it.

Lillies appear to be a bad thing to practice on. :-)

  when you see a favorite picture of yours do not erase it off your chip. Put it back in the camera and look at it on the LCD screen and now you know what perfect always looks like. If you out in the sun take a dark black cloth(like in the old days) and cover yourself so you can see your screen, but please try not to mess up your hair
