Preset photoshop to open images by using embedded profile

[zizibe1]

Hi,

When I open a new image in adobe photoshop, every time a message box opens and asks:

Embedded Profile Mismatch

The document "Screenshot ..." has an embedded color profile that does not match the current RGB working space.

Embedded: Display

Working: sRGB IEC61966-2.1

What would you like to do?

• Use the embedded profile (instead of working space)

• Convert document's colors to the working space

• Discard the embedded profile (don't color manage)

How can I preset that a new image always opens automatically by using the embedded profile (instead of working space)?

Thank you in advance.

Well, one round-trip sRGB-AdobeRGB-sRGB gets me this histogram difference:

One could mitigate the effect by converting to 16bit first, but an automatic conversion of incoming 8bit images would not do that.

And while the gradients do include »Dither« I am aware that photographic images would usually be considerably more noisy than this test-image so the issue may be considered »academic« (but not »theoretic«) by people who only edits photographic images.

The histogram indicates some degree of color change, but it's not discernible on screen, and certainly wouldn't be in offset printing—plus there would never be a reason to make the round trip.

Whether and how often the roundtrip happens for an image is not necessarily up to just oneself – one passes on an image and it may get converted yet again … (edited)

If one has already converted it twice the accumulated changes will likely get stronger – and while they may still be imperceptible I would like to avoid them.

Right, imperceptible. And the relatively coarse offset halftone screen is never going to resolve the (invisible) artifacts from the conversion. On the other hand if you expect to use the full color gamut, sRGB has real world deficiencies, which will eventually show up on press.

c.p.'s point here is not gamut clipping. It's adjustment layers. They have different meanings in different color spaces, so an automatic wholesale conversion will then cause files to change appearance. That is unacceptable by any standard.

And another point: Adjustment Layers in layered images may have somewhat different effects in different RGB Spaces.

Coated FOGRA39 is fine if that's what the printer wants.

But what's this -

         Color: “Embed Color Profile: Apple Wide Color Sharin…” - on

- where on earth did that come from - ?

Oh, I'm sorry. I should've written:

File > Save As…

Format: TIFF

Save: “Layers” - on

Color: “Embed Color Profile: Coated FOGRA39 (ISO 126...” - on

The printer companies never complained about this color space.
