Edited images are having unwanted saturation added to them Answered

It seems that if I upload a photo to an instructable that has some form of text on it (be it from photoshop or pixlr) then it gets saturation added to it. However any raw photos that don't contain anything extra don't get this saturation.

This has also happened on multiple instructables.

Just wanted to update this topic. I was writing another instructable today and came across the issue again. I then tried messing with some settings and it turns out turning OFF the selected by defeault: "ICC Profile: sRGB..." in the Save As menu fixes the problem.

when you export these images from photoshop, are you using web-optimized values? we re-process images that are uploaded, but not to alter their colors. are you exporting in adobe RGB color space after making alterations in photoshop?

I did a bit of searching and found that my photoshop destination profile was set to 'Working CYMK - US Web Coated (SWOP) v2' however if I change that to 'sRGB IEC6xxx..' then it appears to look exactly the same.

Previously I was saving my images as a JPEG through Photoshop and in the dialog box there is a checkbox for 'ICC Profile: sRGB6xxx..'

Not sure if that helps at all. The over-saturation effect also happened on the integrated pixlr photo editor.

This sounds like a bug that was reported a little while ago, and fixed as far as I knew. I'll pass this to our team of developers, but they will likely not see this until at least this coming Tuesday.

In the meantime, are your images by any chance PNG's? Try saving them as JPEGs and reuploading. This approach has solved the issue for my own pictures when this was happening to me.

No, none of them are PNGs. My camera takes the photos as JPEGs and I always export them from photoshop at a jpeg.

I have attached a side by side comparison. The picture on the left is the same as the first 2 photos in the instructable (raw images from the camera) and the third picture in the instructable has been retouched to be lighter.

You can see that the images on the right in the bottom left corner of the wood there is higher contrast/saturation making it look green.

Have both images been edited? It could be that some color management info which was added during editing (to match your setup) is stripped off here at I'bles...

Normally only the images that have text on them are the ones I touch up, so that could be possible.

A screen-shot for comparison might be useful for the development team to see.
