Don't misunderstand this thread. I do all my editing and processing in PhotoShop CS. I think it is an incredible program but when I am trying to learn and understand more about principles of photography and exposure I find that PhotoShop is not a great tool.
Having said that, I decided to open ZoomBrower a few days ago and use it as the organizational program for my image library primarily so I can preview and see thumbs othe library quickly, which even using PhotoShop's browser does not do this as well.
After working in ZoomBrowser I realized that in Preview mode I can see thumbs, a larger scale image and all the camera and EXIF data plus the histogram. As I go through folders of images I can easily make comparisons in settings and with it all in front of you at one time you can make sense of it. Sure enough I can see that when the histogram looks as it should, those pictures always look great and appear to be properly exposed. The same goes for pictures that are either over or underexposed. The histogram usually represents that. It makes a lot of sense when you see the histogram, the EXIF data and the image at once.
I am now hooked on ZoomBrowser because of the ease of use and its ability to organize a large library with keywords, ratings, etc..
I do have 2 histogram questions to throw in here. I have some pictures I took at a large park and that day there were beautiful blue skies and wispy white clouds. The pictures look great and had nice contrast and good color. However, according to the histogram in ZoomBroswer the image was slightly underexposed (if I am interpreting the histogram correctly).
Does the histogram always need to look perfect to determine if a picture has been properly exposed? Is there a degree to which the histogram might technically be off but the picture should not have been taken with a different exposure?
The other question is why the histogram shown in PhotoShop differs from the one shown in ZoomBrowser? Are they representing the same thing?
Below is an example of this and then I have shown the 2 histograms.
