Dull Glasses

[Jodie Williams]

Hi Damien, I have this issue with the dull left (screen) glasses and not sure if the channel mixer will fix this or I need to post in another section. I have looked at the class tutorial and found that I can fix colour cast, I don't see this a color cast issue, but could be wrong.

.I actually just fixed it with a simple brightening and contrast  adjustment

You're right, this is just a lack of contrast.  A normal Levels adjustment will fix it.
