Gradient Maps Changing Colour Upon Export

[matthewd56729126]

I've blended together a number of gradient maps to reach a colour scheme that I'm really happy with. Each gradient map has a blending mode. Upon exporting the colours change. Does anyone have any ideas? I've attached screenshots of before and after export. I've also tried to convert to smart object, however it just wipes away the blending mode it seems like?

Two things:

First, your file is untagged, which means the colors are undefined. Always make sure the color profile is embedded. All web browsers and Windows Photos will read this profile and represent the file correctly.

But there's one more thing that may be even more critical here: You have a lot of noise in this image. This means you must view at 100% to get a reliable representation on screen.  Any on-scrren resampling will diffuse the noise and introduce numerical values that arent there in the original data.

100% has nothing to do with size. It means one image pixel is represented by exactly one physical screen pixel.

Here's the thing: For performance reasons, all blending and adjustment previews are calculated on the on-screen version of the image. When you are zoomed out, that means a resampled and softened version of the image. Pixel levels are averaged out. So the adjustments are calculated on values that aren't really there.

When you merge, commit an adjustment etc, the numbers are re-calculated on the full original data, pixel for pixel.

Viewing at 100% avoids all this and renders the whole issue moot. You see every pixel before and after, and so nothing changes. Always view noisy/binary images at 100%.
