On the other hand, other apps do not display the same colours as these
apps. For example, iView Media Pro, iPhoto, Preview and the Finder all
display images identically... but not the same as the first set of
apps.
Of those, the one I know uses embedded profiles and display
compensation automatically is Preview. If you have an image file (such
as a TIFF) with a profile embedded, Preview will show the same thing as
Photoshop. Perhaps your files don't have profiles embedded, or you're
using a file type (such as PSD) that isn't fully supported by
Preview...I haven't tested all permutations, just TIFF.
I have a couple of questions:
1/
Can anyone explain why not?
2/
Somewhere between the two sets of apps, falls Internet Explorer 5.2.2,
which display images the same way as the 2nd set of apps, when
ColorSync is turned OFF in its preferences, and when it is turned ON,
it over-saturates and raises the contrast. Since this issue is largely
about making web galleries with iView Media Pro for people to view
using Internet Explorer, I'm at somewhat of a loss as to what I should
do so that people see, via the web, what I see when I'm producing the
actual work.... i.e. with Live Picture, Photoshop and my EyeLike.
How should I handle this issue?
You can only target the average user. So first define the average user
to determine if you should use something like ColorMatch RGB
(predominately Mac viewers) or sRGB (predominately Windows viewers). I
suppose if you can't decide you could create a custom space based
either ColorMatch RGB or sRGB and select a gamma of around 2.0 (which
isn't between 1.8 and 2.2, but probably close enough). That custom
space you use exclusively in Photoshop, since nothing else will use it
anyway.
Next, calibrate and profile your display to 6500K and the target gamma
(1.8 for Macs, 2.2 for Windows, and 2.0 for something in between) so
that non-color managed applications will present something on-screen
similar to what your average viewer will be seeing. Turn ColorSync off
in Internet Explorer since most users won't have it on, or won't even
have the option.
Photoshop has a proof preview option to show what the image will look
like on a Macintosh (gamma 1.8) and Windows (gamma 2.2) display. Go
back and forth between them, or create a new view and apply two
different proof previews at the same time, so you can see what
compromises will be made between them.
