Hello,

I'm having a weird problem on my work Mac Pro, which is running El Capitan, when viewing pictures in Quick Look (and Preview).

My job involves a lot of photography, so this is pretty annoying when I'm looking through multiple images, and trying to compare them, or showing people.

So, if I select a Jpeg file in the Finder, and press the space bar to launch it into Quick View, it (usually) looks fine.

However, if I then resize that window, the image density and contrast changes and becomes extremely dark and contrasty.

Closing the image and reopening it in Quick View usually displays it as dark and contrasty again.

When scrolling through images in a folder, using QV, some images remain fine while others look initially fine then change to the dark/contrasty view.

Nothing I do seems to be able to fix this.

I've noticed it also happens the same way in Preview too, although I don't use that very much.

I use QV a lot to flick from one image to another just to see differences or see them in a quick handy way, but this weird colour/density/contrast behaviour is making it unusable.

It also happens on my (older) Mac Pro at home, also running El Capitan, but to a lesser extent, and isn't such a problem.

When my home Mac does it, it seems to happen about a second after the image is displayed or I have resized its window, and the change in density/contrast happens quickly in large blocks until the whole image is affected, sometimes leaving a large block area of the image unaffected.

I've tried Googling this but cannot find any info about it.

Can anyone help please??

Thanks
