Bonjour à tous,

Je suis nouveau sur ce forum. Et je me mets à la photographie numérique. Je me suis documenté sur les différents espace colorimétrique et autres profils ICC. C'est ma fois passionnant 

J'ai fait l'acquisition d'aperture et je voulais, à l'instar de photoshop qui est parfaitement clair, savoir quelle est l'espace calorimétrique de TRAVAIL sous aperture 2.

Trouvé sur le site apple support. Mais cela ne me parle pas trop...

Setting your colorspace in Aperture
In contrast with Adobe Photoshop, you don't have to set your "workspace." Instead, Aperture will always work in a wide gamut, except for when you apply Onscreen Proofing, which shows you how your work should look in final output. When you know your project is bound primarily for one medium, such as RA-4, it's a good idea to leave Onscreen Proofing on all the time while editing, which would give you the equivalent effect of setting your workspace.

After you're done editing your project, set the Export Presets to match the ColorSync profile that you use for Onscreen Proofing.

Tip: In some cases, the profile lists don't match (an issue resolved in Aperture 1.1 or later). Adobe RGB, for example, is included as an Export Preset option but not as an Onscreen proofing option. Try using ColorMatch RGB or Wide Gamut RGB when proofing for Adobe 1998.
To make your color settings, using RA-4 as the example output, you would do this:

From the View menu, choose Proofing Profile > sRGB IEC61966-2.1.
Look in the View menu again. Notice that there's now a checkmark next to Onscreen Proofing, which only appears after making your initial profile selection. From now on, you can turn it on/off by selecting this menu command or using the Shift-Option-P keyboard shortcut.
From the Aperture menu, choose Presets > Image Export.
In the Export Presets dialog, locate the ColorSync Profile pop-up menu, and choose sRGB IEC61966-2.1.
Click OK.


Merci d'avance...
