... the thumbnails on my mac are even off with colour.
thanks in advance. this is an urgent matter
Yes, the file icons for ProPhoto documents will look severely washed out. The icons for Adobe RGB 1998 documents also look washed out, but less severely so.
That's because Photoshop neglects to convert the values of the pixels put in an icon image from the document colour profile to the icon image colour profile.
Apple recommends icons contain sRGB images, but Photoshop developers insist on not following Apple's icon guidelines.
ok. but what about when i email. is that just my email provider?
and the main issue is when going to a photo booth they coe out s u are saying the icons are?
Ask your email recipient to help solve this. Send them a JPEG and have them send it back. If it comes back correct to you then you'll know that it must have arrived correctly at their end. Of course, if it comes back wrong then you'll not know which leg of the journey was problematic and you'll have to investigate further.
great 2 out of 3.
any comment on the printing?
No, I don't have enough information to make a judgement. I think you will get better guidance from forum members with more experience of contemporary printing than I have.
