Hi, Dave.

As you can see the colour of the image modify significantly and it never happened before. Also the settings are the same as always. It doens't make sense. 

Tanks,

Fernando.

This image is all noise. You must view at 100% to get an accurate preview.

100% means that one image pixel is represented by exactly one physical screen pixel.

All adjustment/blending previews are calculated based on what you see on screen. Zoomed out, that's a resampled and softened version, which means that all those different pixel values are averaged out. In other words, the calculations are performed on false pixel values.

It's done this way for performance reasons. In a "normal" photograph it doesn't matter, but it becomes essential for very noisy or binary images with sharp pixel transitions.

It is intentionally noise.

Yes, I understand that, I'm trying to explain why you see what you see.

You're probably getting a lot of gamut clipping here, if this is converted from something else to sRGB. But you need to check at 100%.

[Fernando Ferreira Leite]

I understood now. Thank you for your help.

Take care,

Fernando.

A couple of questions.

1. When you export do you convert to sRGB and Embed the colour profile. You should do both.

2. When you view the exported file are you viewing in a colour managed application. If you are and you did step 1 then it should look the same. If you are not using a colour managed application to view then all bets are off.

You export to JPEG and then view it where? It should and will match the original in all color managed applications if you've embedded the color space into the document. Non color managed applications, not going to match.
