Once you find the way to access the histogram of a photo, you can start to read it. On its horizontal axis you find a scale of brightness that goes from zero, black, to 255, white. Perfect histogram: how to get a picture with the correct histogram.
Yes, the concept of perfect histogram not only exists but is desirable, especially in those situations where you have control of the scene already during shooting. In these situations you can use the histogram to figure out how to adjust the exposure and then get the desired result.
Take for example a snowy landscape; if the histogram shows you a lot of medium tones, you will probably have to increase the exposure (without overburdening outside the upper limit) to make the snow white and bright instead of gray and dirty.
Even in post-production it is possible to modify the histogram with various types of adjustment, of which the most obvious is the brightness. At the end of the reading, open your favorite photo editing program and experiment with the brightness and tonal adjustment tools to see how it affects the histogram.
In some more difficult situations, with extreme lighting conditions, it may be difficult if not impossible to contain all the information of the shot within the range (the range 0-255) of the photo. In these cases you can adopt some tricks, such as HDR, ND filters or the use of the RAW format that offers more range and information recoverable in post production (Fashion Photographers Los Angeles).
What is the RGB histogram
The same type of instrument is the same as that of the channel relative to brightness, but which separates the three fundamental chromatic components. With the RGB histogram you can easily understand if the colors of the shot are in line with those you expected and especially identify any dominant to correct.
The graph of the histogram shows how the pixels of the image are distributed on the basis of their brightness, but to learn how to read it correctly. The left sector represents shadows and dark tones, so if one of your photos has a greater concentration of graph in that part it means that most of the pixels that make up your image are dark.
The sector on the right represents the lights and light tones, so if your photo has a greater concentration of graph in that part it means that the majority of the pixels that make up your image are bright as done by Fashion Photographers Los Angeles. The middle part of course represents the middle ground.
