FrodoNL Posted November 10, 2022 Posted November 10, 2022 Hi, I'm a wedding photographer and I'm struggling with removing Moire from suits of the groom. A lot of suits will generate moire in my pictures on different places in the photo. I was hoping that Affinity Photo v2 had some slider to remove irregular Moire patterns from the suits. I've tested two other products and with a slider it is easy to remove Moire: Feature Request! I'm a bit disappointed it is not in V2, as more and more camera's lack the AA filter. As I'm familiard with Affinity Photo this is my only thing to use another product, but I can't do this editing in different products as this affects my workflow too much. Is there an easy way to remove this kind of Moire? Any help will be appreciated. I've tested blurring but I think this is nog a constructive way of removing these moire patterns. Thanks Roland
Dan C Posted November 24, 2022 Posted November 24, 2022 Hi FrodoNL, There's no specific Moire tool, we have an FFT denoise tool and you can use this alongside blurring and adding noise/cloning. Lee and relax 1
firstdefence Posted November 24, 2022 Posted November 24, 2022 Don't think the FFT Denoise will work on suit moire, either the stripe wave pattern nor the rainbow effect. The rainbow effect can sometimes be corrected using a colour matched pixel layer set to colour but the wavy moire is harder to fix. iMac 27" 2019 Sequoia 15.0 (24A335), iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

Lee Tnx. But indeed FFT Denoise does not remove moire from a suit. Using cloning etc is very time consuming and I can't get good results. A slider is what I'm really missing. Removing moire from hundreds of photos from a wedding is for me a must to automate. For now I need to think how to approach my workflow and optimize it. Moving to other software is not what I want because of my build up experience in Affinity. But for now the options are limited..
NotMyFault Posted November 24, 2022 Posted November 24, 2022 Could you please provide an example file? it would be sufficient to get only a selected area, but the file should be RGB/16 and uncompressed (no jpeg). The area should contain different moire issues, and areas no impacted. is the moire issue more in color, or affecting grey areas (much harder)? one tip of using fft denoise: often the issues are not horizontal / vertical. If they follow a straight line, i got far better results by rotating the image temporary to align the moire to the horizon.

NotMyFault Posted November 26, 2022 Posted November 26, 2022 I just posted a tutorial how to reduce moire with Affinity Photo 2 using the new live bandpass mask. Looking for test images which I can use for a video tutorial. ashf 1 Goodby Forum, thanks for good discussion and so much support from great peers and Affinity staff.

ashf Posted November 26, 2022 Posted November 26, 2022 I think FrodoNL is talking about this kind of moire.
NotMyFault Posted November 26, 2022 Posted November 26, 2022 A hard nut, but not tot bad: the moire removal needs a curves adjustment to compensate for the contrast loss. Then, structures like dark lines must be masked out. hard moire case.afphoto ashf 1 Goodby Forum, thanks for good discussion and so much support from great peers and Affinity staff.

Thanks Roland Just a hint: if you are taking and processing the images yourself: moire often can be avoided. It can be the result from premature sharpening. When you use an image with strong sharpening, and then resize to a smaller size (for web etc), this can create or dramatically amplify moire. The best practice is to not apply sharpening before resizing. Sharpening should be the last step, and it must be done individually for every export size. Do not sharp globally, but only on areas like eyes where required. Goodby Forum, thanks for good discussion and so much support from great peers and Affinity staff.

ChopperNova Posted November 26, 2022 Posted November 26, 2022 It's been a long while since I've done this, but I recall working in LAB color space (in Photoshop) and did whatever only on the lightness channel. Of course you need a color image, and you must remember to change back to your final colorspace before exporting. Sometimes the camera manufacturer's own terrible software will have moire reduction that helps with a specific camera. Topaz DeNoiseAI is a standalone/plugin than might work. You could try the trial.
