White Balance

These are three different pictures showing the different color balances. The first is the original, which was too dark. If you move the temp. slider to the right on photoshop, it corrects the higher color temperature of light. For the second one, There was a lower color temperature of light, so the slider can be moved to the left to correct it. The last photo is the finished product, after both changes were made and it was corrected.

  • Describe everything you can about white balance and color temperature
    • White balance is when you remove unrealistic color casts on photographs, so that people or things who appear white in real life appear the same color in the photo. The color casts are usually some shade of blue, orange, or green. Color temperature is the color spectrum radiated from a "blackbody." "red hot" is one temperature, while "white hot" is a higher one. When you balance the red, blue, and green channels, the whites and grays of the photo look neutral.




      • To correct white balance, you can set your camera to auto white balance before a picture is taken, or work with it later in photoshop. Thsi works ok wiuth flash indoors and outdoors. You can also use Shade white balance, Tungsten, Cloudy, Daylight, and Flash.
      • In photoshop, you can use the coor balance tool to correct global color casts. you can adjust specific ranges like shadows, midtones, and highlights. You can also use levels to correct white balance, and address specific color values to different channels. You can also adjust colors of the picture by using the hue/saturation for color control, and decided what hue and how saturated you would like your photo to be.
