Bonjour, depuis peu, quand j'envoie une photo de camera raw vers PS, j'ai une grande perte de netteté et de peps. CR 16.1.1 et PS 25.4. Sur la copie ecran jointe : à gauche CR, à droite la même dans PS. On ne voit presque plus les étoiles et elle a perdu en netteté. Je ne trouve pas d'explication.

Merci d'avance pour votre aide

    Are the pixel dimensions on the Camera Raw workflow settings the same on all computers? If Camera Raw is set to lower pixel dimensions on one computer, conversion to Photoshop will be smaller on that computer.

    For the image in Photoshop on each computer, is there any difference in the width and height in pixels when you choose Image > Image Size?

    I made some new tests, and it seems that the latest version of PS has à problem with Mac studio with apple M1 max, as I do not have that issue on my macbook M1 with same OS, same CR and PS version. Can anybody help ? Is something running to correct this such a bug ?

    Hello, is there really nobody who can help ? I am quite desperate not to be able to work on PS on my Mac Studio. The photo opening is of very bad quality.

    I have absolutely no idea about what's causing this, so I'll tag @Conrad_C who is a Mac user, and hopefully might be able to help you.

    Loss of photo quality between camera raw and PS
     
     
     

    Hello, recently, when I send a photo from a raw camera to PS, I have a great loss of sharpness and pep. CR 16.1.1 and PS 25.4. On the attached screenshot: on the left CR, on the right the same in PS. You can hardly see the stars anymore and it has lost its sharpness. I can't find an explanation.

    Thank you in advance for your help

    If you view the image at 100% in both applications, do you still see a difference?

    When working with image detail like sharpness/sharpening and noise/noise reduction, you must view the image at 100%. Any other view will be inaccurate and misleading because the image has been scaled. At 100% view, one screen pixel is used to display one image pixel, and this is the only view that presents you with a true representation of the image.

    (if you have a 4k or higher monitor, use 200%)

    Thanks for your answer Per. 100% or not, it is the same. And I did not use sharpener or noise reduction. I do as I always do and I never had this issue. And I do not have the problem on my macbook. 

    I made another test this morning  : register directly from CR to the original file, in psd. Then open it directly from the file in PS, same problem. Great loss of sharpness. So it is not the passage direct from CR to PS, the problem must be in PS 25.4.0. Is there something in the preferences for this latest version that has to be changed ?
