My guess is Image Stone Viewper displays the heavily processed JPEG thumbnail, which the camera created for viewing shortly after capture. Photoshop, on the other hand, (and more specifically Camera Raw) will be creating/displaying an unprocessed rendition of the raw file.
If you want the raw file to look like the camera created thumbnail, go to the Camera Calibration menu in ACR (Adobe Camera Raw) and choose the camera profile which you are using in-camera (such as Camera Faithful).
thx for your support .
by saying : "go to the Camera Calibration menu in ACR " do you mean to go in photoshop to : edit-preferences - camera raw... and than to mark the thumbnail of "make default specific to camera iso setting " ?
soory , but i am not super technologiest ....
When you first open a raw file, Photoshop's Camera Raw plugin should open the file for initial processing. See this screen shot:
By default, the "Adobe Standard" profile will be chosen. However, you can choose one of the recreated camera profiles. This will apply the tonal and color changes which that particular Canon profile would have in-camera.
I usually stick with Adobe Standard and do my own corrections to personal taste.
thx for your help , but i am not sure it solve the problem .
hereunder you can see the file as shown from the photoshop after : camera faitful
at the second picture you can see the picture from the IMAGE STONE VIEWER
it didnt change the result .
i have to mention that with my former screen , i didnt see any differance between the photoshop and the image stone .
I meant to use Camera Faithful only as an example...To find the exact profile which your camera is using, you'd need to look in the "Picture Style" menu of your 5D Mk III.
However, this could be due to a corrupt/defective monitor profile. Open the Start menu and type "color management." What profile is being used as default for your computer's display?
Can you show how the JPEG compares between both apps? How about the same CR2 in both apps (as you are comparing a JPEG to a CR2 it may help to see the same file in both apps).
