Using Histograms on Photoshop for Color Correction
Histograms are bar graphs that are made of frequency distribution. They are made with the widths of the bars, created to be proportional to the class that divides the variable. This variable is divided by the height of the bars that are proportional to the class frequencies. What this basically means is that you will be able to make colors in your photographs more vibrant with histograms.
Step 1: Choose Picture
The first thing that you will need to do is get a picture that you wish to do color correction on. It is always a good idea to have a picture to play around with first before you start with pictures that you wish to use or to keep. Once you have found the right picture, open up your Photoshop program and begin to get to work.
Step 2: Histogram
It is important that you understand what is what with your histogram. The axis that is horizontal is what will represent the overall tone of the picture. The axis that is vertical will be what will represent the quantity. There are over two hundred and fifty shades in the histogram. You should know that when there are a lot of dark parts on your picture, the histogram will show quite a bit of black that will be on the left hand side. If there are a lot of brighter parts, then there will be quite a bit of black on the right hand side.
Step 3: Open Histogram
In order to open up the histogram in your Photoshop program, you will need to choose the Image drop box. Histogram will be an option that you will be able to choose from there. The histogram is there to show any problems that may show up with the tone or the overall color of your photo. The four sections of histograms include: red, blue, green and luminosity.
Step 4: Levels
When you are in the histogram portion of Photoshop, you will find that there is no dialog box that is available for you to be able to make any type of corrections. However, the levels will be able to adjust the layers on the photograph. Levels will produce to you a histogram that contains a dialog box that you will be able to use for any type of corrections. The histogram that is shown on the levels option is the exact same histogram that you will with the histogram option.
Step 5: Fix
Once you have found the dialog box where you will be able to make corrections, play around with the levels from there. You will see what levels do what. Make sure that you are able to view each change that you make without having to save the image until you are ready. Once you have found the correct tone and color of the picture, simply hit the save option and you will have your new and much more colorful picture.Popular P&S Cameras for High Quality Photos:
