Tutorial: Using Black & White points in Photoshop to clear up an underexposed picture
Step 3:
While still holding , scrub your white point slider to the left on the histogram. The key here is to slide the white point until your overlay image starts to get to a point where it turns pure white. This is where we will be setting the white point of your image, thus adjusting the entire histogram to account for the new white point of the image.
Step 4:
Now that we’ve found the new area of the image we want to set our white point, we have to actually do it. Locate the tool, as seen above, and click it once to highlight. Your cursor should now change to the little Eyedropper icon (Depending on how you have your preferences set up in Photoshop, this may or may not happen.). Take the White Point Eyedropper and find the area of the image we designated to be our new white point, click once. You should see an immediate change to your image and a new histogram should be generated in your Levels window as well. If the desired change is too much, or too strong, you can keep clicking around until you get a nice new balance for your white point.
Step 5:
Now we will repeat steps 2-4 above, but on the opposite side of the histogram, the black point. Again, we will hold the and scrub our black point slider on the histogram, but this time we will be looking for the image to turn it’s blackest.
