Why is everything gray with a N

Looks like you applied a Filter. On the screen where the CIA lives, do the Intensity, Focus, Color, Form, Image, Shutter softkeys have red text in them?

• You are correct. I saw another post that stated Make Null and Filter. I saw a filter on under the color option. Got it turned off. Needed to play around with the Make Null option to finally clear the problem. Took about 50 mins to figure it out. I had tried loading an older file but this didn't fix it. So I really lost a couple hours of work. 

Thanks for follow up with your answer.
