Here is a picture (of many) that I took from a book with my phone camera.
The problem is that the background is too grey. I want it fully white. I have adobe Photoshop CS6. Does anyone know how I can fix this?
Note: I need instructions, as I need to do this to many other pics.

With your file open, choose Image->Adjustments->Levels. You’ll get this:
Now bring the two outer triangles in like this (you’ll need to play around with this until you get something you like):
You should end up with this!
