Hi,
I am using a program which converts image files using quicktime
technology to 2 thumbnail sizes.
Can anyone tell me how quicktime does this as when it converts the
colours are not quite the same?
Can anything be changed to make it convert colours more accurately so
it matches how the image looks in photoshop?
It really depends on the application - the Quicktime graphics import
APIs have options to honor embedded profiles or to ignore them, so you
need to ask the developer how they are using it.
It's possible the app is converting your images from the
embedded/tagged space into your chosen Default RGB (as set in the
colorsync utility), but then not embedding a profile for that
destination space. To determine if this is the case, open the original
and the converted file in Photoshop, and set the color space (Assign
Profile) of the converted file to whatever you have set in ColorSync
Utility as your Default RGB. If they now match then you know what's
going on...
