Gray gamma

• Salve! Passando da camera raw in photoshop mi si apre la finestra dove dice che tra lo spazio lavoro 2.2 e spazio incorporato 1.8 non c'è corrispondenza nella gray gamma!prima non me lo ha mai chiesto

Ignore it. Go to Color Settings and disable that warning. It tells you nothing useful.

Just keep color management policies set to "preserve embedded profiles". The embedded profile will then override your working space. This is how Photoshop is designed to work, and how color management is supposed to work.

There is no reason the embedded profile should match the working space.

...but aside from that, you probably should have 2.2 as your working gray, not 1.8. The reason is that single-channel view, in itself untagged grayscale, will display using your working gray. This means it will display correctly on screen, since all monitors are close to 2.2 natively.

Grazie! Scusa ma devo cambiare qualche impostazione?

I'm curious why ACR is producing a grayscale image? I'm presuming a colour raw file, are processing something else such as a TIFF file?

Io converto in acr in bianco e nero!poi passo in photoshop

I would have assumed that this would create a neutral RGB file into Photoshop.

I was surprised too. I discovered more or less by accident that B&W in ACR actually sends out grayscale in GrayGamma 2.2.

It's a bit risky, and monochrome RGB would have been a safer option. But Gamma 2.2 should work in most situations, so as grayscale profiles go, this is the best pick.
