I have Photoshop CC. When I open an image in Camera RAW, the photo looks fine. When I open the image from Camer RAW, no matter if I make adjustments in Camera RAW or not, the image is very grainy when it opens. I have gone back and reopened images that were fine before, but now they are grainy also....but only on the PSCC screen, not on the Camera RAW screen. What have I done to cause the images to look grainy?
