I have large 8 bit files shot with a leaf back. Unfortunately I didn’t shot them at a 45 degree angle so I have large tiger striped moire patterns. What steps should I take to remove them?
These will go to print so I would rather not use too much "blur" or "Gas" filters.

Thanks.

Micah,

What is supposed to be at a 45° angle? Can you please post a link to an example of the images? Thanks.

First view at 100% (Actual Pixels) to make sure they are "real" Moire and not just a viewing artifact caused by interference with your monitor’s pixels.

If you photograph an object with dominant stripes (such as a striped shirt) at the wrong angle to your digital camera’s sensor, you might see a heavy moiré.

You may need to re-shoot the subject at different angles and then replace the moiréd parts of the first image from one of the other images.

You will also need to proof them at the same screening (lpi and angles) that you are printing at. Its not a real predictable thing.

If the "moired" image are placed at a reduced size sometimes that helps.

Proof them.

I wonder if one the channels has a decent linearized version of the moire area that could be used to replace the moired channel(s). Disregard if the moire shows up in all channels.

Again, a link to a sample moiré image would be helpful here.

I’m a digital tech on a commercial shoot for a large client, so posting an image would be impossible.

If you tilt the camera at a 45 degree angle, most moire’ will be eliminated.

I did solve my problem though.
created a new layer>chose a brush>sampled color>changed layer to Color mode>lowered transparency>"painted" away the moire.

Worked quite well.
