Histograms are the only way when shooting to get an accurate representation of your exposure. Without it, you could look at your screen and think your photo is exposed properly but then look at them on your computer later and realize everything was underexposed or overexposed. Here are the basics from the first video segment.On the Water by Cazillo, on Flickr
- Histogram is a graph representing the saturation and luminance in an image
- Histograms assist in exposure evaluation
- They are not the end all be all, rather allow you to make more informed decisions about your photograph
- In-camera histograms are generated from JPEG previews
- If you shoot RAW the histogram in your RAW converter (Adobe Lightroom, Adobe Camera RAW) could differ
- I do not use an RGB Histogram, prefer to see overall colors for general exposure, usually don't need to see individual colors
- Know how to turn it on....and use it!!!
- Shoot to the RIGHT of the histogram, don't loose data by having flat spots on the right of the histogram.
- 1/2 of all data in your digital image is in the first 1 stop or brightest area of the image
- There are exceptions to every rule in photography, its not perfect but one more tool in our arsenal
Moral of the story is use your histogram all the time, your photos will improve. Enjoy!
