Is there a good technique to remove or prevent a moiré pattern from a digital camera capture? I work for a small real estate newspaper and lately the majority of images we have received from Agents have been unretouched jpeg files from digital cameras. In many of them we are seeing a distinct moiré pattern, usually where the repeated geometric patterns in the design of the house exist. Typically this is usually the roof tiles, or siding of the house. I have tried to remove the moiré in PhotoShop using the filter>noise>deskpeckle, the filter>blur>gaussian blur and the filter>noise>median, and Katrin Eismann's LAB method all with limited and unsatisfactory results. Any suggestion?

Digital Moire is very hard to retouch out and almost impossible if the area has detail in it you want to keep. Have your photographers take more than one shot. If they are hand holding the camera, then each shot will be tilted slightly different from the next one. The moire pattern may not appear in the same spot. Then cut and past parts of each to make one good one.

I create marketing tear sheets and brochures for high pricetag real estate and I know all to well the problems you're having.

The best answer is to make sure the image is as high-resolution as possible.

Failing that, I've had good luck using the "Equalizer" plugin from KPT6. In case you're unfamiliar with this, it is a discresionary image sharpener, that splits images into "channels" based on different ranges of image feature resolution, which can then be sharpened and blurred independently.. It's kind of tough to describe, but can work woders that Photoshop's USM can't touch. Highly recommended.

I highly recommend the Eye Fidelity Tools plugin by DVP. It is the best I've tried. You can remove moire and enhance the colors at the same time. Here's a website with a demo.
