Me too.

You are using JPEGs/ developed images rather than RAW for upload into the shop, right?

At any rate I do occasionally see this wave-like opposite-colour stuff on heavily downsized images that have been downsized not by an image program but by website software/ upload - even Imgur.

You can see it here on the trousers as well, even if you go to full size (as available). I believe this image only went through Imgur.

(Side note: on a notebook monitor you may not be able to see the difference.)

I did wonder if it was due to the way the photos were manipulated for the web, after I posted the photos - I hadn't noticed the wavy pattern of the blue and rust splashes, especially on the left just under the collar. I can see a similar affect in the trousers in the above photo, but not in the shirt in the same photo.

It's a great shirt Simon, and I'm perfectly happy with it, but you should probably upload some new photos to the store just so the detail shots show the fabric as it truly is. The photos of the cobalt shirt have a similar affect, with splashes of pink:

Hmm will do

I totally see the artifacts too. It almost looks purple for which I would blame a strange moiré effect. I think the salt and pepper fabric was difficult to capture too.

I don't know if the downsizing of the jpegs are to blame as suggested by Nick or if the effect is already in your pictures?
Salvs close up image looks actually better than the shop pictures. So it's doable.

This seems a lot of work but better than disappointed customers (or not buying because they don't like the colorful

Thanks Flo, helpful.

I'm pretty sure it's not on the original images. Today's digital SLRs and system cameras are too good to render colour that badly - even entry market models.

From the second link:

The paradox of this phenomenon is that the quality degradations of moiré most often occur with images that otherwise possess extremely high image quality. After all, any lack of optical sharpness would naturally blur detail and spread the information over multiple photosites on sensor, preventing misinterpretation by any one pixel. Moiré is a beast of precise imprecision.

I believe this is what happened here. Image compression might make it worse. But the fine pattern is just a bitch to get right.
