Photoshop Tutorial -Easy Tip For Using Photoshop To Remove Gray In A White Area
This is a SUPER FAST PHOTOSHOP TIP for cleaning up an image that has a gray tint to the white surrounding the subject; which is a common problem with scanned images. The great thing about this technique is you do not need to make a selection.

Step 2. Using the text menu, goto: Images/Adjustments/Curves (shortcut on a mac is to hold down the apple key and press M). Use the horizontal slider and slide it to the left. As you move the slider to the left, you will see the light gray start to fade from the surrounding area. Below are the curves settings I used:

Step 3. Here is the image after the curves, I have the info pallet next to the image to demonstrate the area around the subject is a true white. The numbers circled are now 255. You do have to be careful because you will clip some of the light gray from the image.

Step 4. You can see how I lost some of the midtones on top of the image. But this technique is about speed with acceptable results.

Step 4b. Here are the results using a selection

So next time you have a gray tint in a white area around a photo, use this Photoshop tip to turn the gray into white.
