Unwanted on screen ripple effect ending up on print

Aug 1, 2012 6:00 PM

I'll try to explain what is going the best I can.

When I view an image at full screen a slight ripple effect appears, I thought it was just an issue with my GPU rendering settings and the ripple goes away when I zoom in on the image. The problem is this ripple effect is showing up on the printed image. What's going on?

    You're really going to need to augment your description with some images I think.  What you're describing isn't a common problem.

     

    Are you doing 3D rendering?

    Without seeing the file, I'm guessing it's an optical illustion, possibly some sort of moire effect (http://en.wikipedia.org/wiki/Moir%C3%A9_pattern).

    Can you PLEASE post an example image of what you're seeing?  Grab your screen and use the little camera icon on the editor here.

     

    Saying it looks like a Wiki article with some dozens of images in it isn't going to get you pertinent help.

    It depends upon the art.

     

    Is it photograph?

     

    A scan?

     

    Camera noise?

     

    Art created in a computer application?

     

    Could be Adobe's new fuzzy math problem when stretching objects.

    You may have reduced the sharpness by what you did, but if you're happy, we're happy here on the forum I guess.

     

    There can be more sophisticated ways to take canvas texture out of images if ever you're interested.

    ...the ripple goes away when I zoom in on the image.

    You're going to see two types of Morie patterns on screen. One is "real", where the texture or pattern of the subject interacts with the Bayer Array of the image sensor in the camera. It will be visible at 100% view (Actual Pixels). The other is a type of illusion caused by interference of a pattern in an image with the pixels of the monitor. It will disappear as you zoom in. Did it ever show up on print?
