We get PDF’s from our professor to read for homework but they’re often scanned documents, is there a way to adjust the contrast of the text to make it easier to read?
Edit: I’ve got Photoshop but is there a way to do it from a PDF reader?
Edit2: Windows XP, 7 ** Windows or Ubuntu Only **
Answer
You can try this:
Go to Edit>Preferences>Accessibility
This will not change the true contrast, but you can pick contrasting colors of your choice, or one of the defaults, as in the screenshot.
