Hello,
This may be naive on my part regarding the color issues when viewing an sRGB
embedded image in Safari. . .
Quick question, are you viewing an HTML or Flash site?
I ask because Flash actually doesn't use the sRGB profile to render images.
Due to my last position working at an online video game that uses real
photographs and NOT CGI, I did a lot of research to figure out why the color
look of our images wasn't staying consistent from Lightroom to web. Well, it
turns out that the current version of Flash actually uses an old school
(read: way out of date) MONITOR RGB profile. If you take a Safari window
with the image displayed in a flash-powered site and place it next to the
image in Photoshop with a soft-proof of Monitor RGB, you will see that the
images match. In general Monitor RGB will add about 10 points of yellow and
about 15 points of saturation to an image that is embedded with an sRGB
profile. Essentially, Flash makes images look pretty ugly.
When prepping images for my personal flash-powered website I soft-proof with
the Monitor RGB profile and adjust my jpegs before uploading to account for
the shift.
Again, this may be irrelevant to the highly knowledgable members of this
group but I thought it couldn't hurt to add to the discussion.
Thank you,
Kerry
