Adobe Photoshop: Lesson 6

So this is about color correcting images. A little cheat is going to Image > Adjustments > Threshold.Screen Shot 2014-04-28 at 5.51.41 PM

 

To find the lightest part of the image scroll the arrow all the way to the right.

Move it a little bit back to the left because the boy in the photo is the main focus. Then hold down your shift key & mark the white part.

You need to avoid specular highlights. Don’t pick anything bright & shiny. To find the dark area you side it all the way to the left & do the same thing but click cancel instead of okay.

Then go to curves.

Double click on the highlight eyedropper & put it default value. Always work in RGB when doing color correction.

If you put an equal amount of RGB it will always be gray. If you go under Window > Info, you could read the color values of each part of the photo.

Review: Things to Remember (page 220)

  1. It is common for the Color Sampler tool to be used inside the Curves panel, where it

    can be used to mark white, black, or gray points on the image. Using a Color Sampler

    makes it much easier to read the data from one particular point of the image from the

    Info panel.

  2. There are many theories as to which color mode is the best working environment for

    color correction. Unless you are in a color-calibrated environment (using LAB), RGB

    should be the mode you choose to work in for color correction.

  3. A neutral is a gray, or a shade of gray. You can often fi nd a gray area in an image that

    can be used as a measuring tool to see if your colors are balanced. Some photographers

    like to introduce their own gray card in order to have a neutral against which to

    balance. They then crop the gray card out of the image when they are fi nished

    correcting the color balance.

  4. By viewing the Histogram panel, you can tell if an image’s tone curve has been

    adjusted. Even if you make simple curve adjustments, some degradation will occur in

    the tonal values of the image.

  5. The DNG (Digital Negative) format is a non-proprietary, publicly documented, and

    widely supported format for storing raw camera data. The DNG format was developed

    to provide a standard format that all camera vendors would eventually support. You

    may also use DNG as an intermediate format for storing images that were originally

    captured using a proprietary camera raw format.
