Hello,
could someone please explain to me what is going on during the
following please.
I use image capture in OSX 10.2.1 to download images from my Kodak
DC280 camera to a folder on my harddrive. The image capture options
have "embed Colorsync profile" set to off. Then I import those photos
into iPhoto 1.1.1.
iPhoto is set up to open the images in Photoshop 7.01.
When I open the photos in PS7, it claims that an sRGB profile is
embedded. I make now 3 copies of a photo in iPhoto and do the following:
1st: don't modify it
2nd: I assign Adobe RGB profile in PS7 and save
3rd: I convert to Adobe RGB in PS7 and save
Now back in iPhoto I change my preference to open photos instead of in
PS7 back to "in separate window".
In iPhoto the unmodified image looks exactly the same as the one with
the "assigned Adobe RGB" profile. The image with the converted profile
looks much lighter.
Now my questions are:
a) what does this mean as far as what is going on here. Does iPhoto
honor the profiles? What is happening at each of these steps?
b) if iPhoto is honoring profiles, why does the one with the supposedly
original sRGB image look the same as the assigned Adobe RGB profile?
c) is my camera embedding a profile in the first place or is PS7
picking that up from the EXIF data incorrectly?
d) should I embed a profile maybe during the download with image
capture by turning on "Embed color sync profile". Which one?
e) Does embedding a profile mean assigning or converting in PS7 terms?
iPhoto 1.1.1 is supposed to "Retain and display EXIF data".
How do I display that? Nothing shows under "Show Info".
Thanks in advance for all the input.
Sincerely,
Arnold
