Hello Pierre,
Photoshop supports blackpoint compensation (bpc), other apps may not.
As a test, Youcould turn off bpc in Photoshop to see, if its looks more
similar to the other apps.
If yes, thean you have to look if its possible to turn on bpc in the
other apps.
Regards

Hello,
I installed Leopard on my Macbook Pro, and recalibrated my monitor
(using "coloreyes display software with an I1Display -> ICC v4
profile, 16bits LUT, gamma L*). I recently took night pictures with my
DSLR (RAW format), and saw that under nikon Capture NX (which is
supposed to be color aware), the darks are clipped to black. When I
export the picture (TIFF) with the embedded color space (adobe RGB),
the picture looks the same as in NX using preview.app, but in
Photoshop, the picture looks "normal" (i can distinguish black from
dark grey). I thought all these apps were color aware, so there is
obviously a problem here !
To be sure, I created a gradient from black to white in photoshop
(adobe RGB working space), and saved it (TIFF 16 bits, adobe RGB
embedded), it looks OK on photoshop, but greys are clipped to black
under preview.app and Capture NX. Same thing if I convert to sRGB
before saving. The only way to gat the same (or almost the same)
colors in Preview, NX and photoshop, is to convert the gradient to the
screen profile before saving... which is an heresy I think !
So I would really like to know what is wrong, I've no idea if the
problem comes from photoshop or the other apps, or from my monitor
profile ! (I would tend to say that the problem is not in photoshop,
because the L* gamma "pushes" up dark grays, which is what I see on
photoshop : with the standard monitor profile, which hasn't an L*
gamma, this problem is less noticeable).
Thank you for your help !
