Forgive me if my naiveté is obvious, but if Adobe is trying to mimic the basic profile each manufacturer designates as default to render the image visible after import is it possible that the scale or zero point assigned by each manufacturer differs? That is, as ACR interprets what Pentax assigns as “0” in default rendering may be equivalent on the ACR scale to a Nikon “40” to achieve equivalent amounts of default profile sharpening. As it is raw data imported one can then add or subtract sharpening to form their own desired profiles or import settings.

I can not answer this, because I use not a ACR. This only can answer users, which have this ACR and than they can say....yes, for Nikon the ACR default for sharpness is 40 and for Pentax it is 0. I can only say that my LR use a sharpness amount of 25 as a default for my Pentax RAW files....but not a sharpness amount of 0 !

I ask if this is Adobe ACR interpretation used in the studio comparison because I downloaded the images into ACR and get the basic sharpening setting of 0 for the Pentax .dng and 40 for the Nikon .nef. However, if I download the .nef directly into Nikon Studio NX convertor the default sharpening is listed as 0. I do not have a Pentax raw convertor to compare data there. Obviously the Nikon native convertor and the Adobe Standard profile in ACR assign different values for the default sharpening and a Nikon .nef 0 is a 40 as an Adobe .dng and a Pentax .dng 0 is a 0 as an Adobe .dng

Thank you for your reply !

Now when you count in what you wrote and Lessiters post's I think now that my thread do have in that what I wrote a wrong conclusion ! On the other hand, I do now not understand what my LR did....using it's default sharpness amount of 25 for all my own K1,Kp DNG files out of the camera and for this downloaded K1 DNG RAW file of the comparison tool suddenly a sharpness amount of 0

Hello again

Hello KPM2 and the other RAW shooters,

Now I really don't understand why you guys shoot RAW! If you are not in a control of how your photo editor generates the JPEG file for your viewing, then how you can apply your preferable (RAW) processing parameters? Whenever you open such processed file (.RAW or .JPG) with another photo editor, you end up with a different result . I knew that there is something fishy behind the raw processing and that's why I abandoned it after retiring my K-x camera. With a careful setting of the JPEG parameters I can achieve the same great results out of camera, which don't require any PP. And they will be exactly the same regardless who and which photo viewer is using .

We have the control how the photo editor generates the JPG file with a RAW converter. At the end we make a JPG like you and this we share. You use for example a sharpness setting for your JPG out of the camera. I do the same with my LR, but I can change this setting up to my taste and this I can do later - after the shot was done ! I can make out of one picture a for me normal sharpness version for a full size monitor view or print, and a much more sharpness version for the view of 100% crops, or using more sharpness to prepare it for a downscaling (for the small, middle and large DP gallery as an example (ok I never do that and that's why the pictures looks not so sharp, but I don't mind this because you should and can look at the original I upload).

So, it's not that we have no control, the problem in this thread is that we have the control !

For the two pictures in my first post: that is simple one picture in two versions, as if you would make two JPG's of the same scene and use different sharpness and colour tones settings. OK, now my example:

I could make a thread and claim that the first picture was made with a silver K3 III and the second with a black K3 III and I show you via 100% views that the black K3 III do make sharper pictures and also the colors looks better ! That is of cause nonsense, but when some of you download the files and see via a EXIF tool that the pictures was made with different sharpness and color tones they post this and write about this what I really did done.

And this is the problem: the comparison tool use for me now different settings of the ACR, I can still compare for example Pentax cameras there, but I know now that in a compare with a Nikon, my Pentax picture have not the same RAW converter settings as the Nikon picture got.

BTW: I got answers that it is impossible to see the ACR setting. In case of the Pentax DNG files I do see them, because a DNG file do embedded them, like you can read in this answer from me :

it's form Adobe and not my own 'what I think and why I see such info's' I wrote in post's in this thread...

BTW II:  I got answers that I can not see the XMP file of the Nikon Z9, only the one my own PC made XMP file:  when as others wrote DP ( and I thought the same) use the default values of ACR for the cameras, there is no need to send also their XMP files, this XMP files should be the same your PC or ACR make, when you let ACR use it's default setting for this cameras Only for the Pentax DNG file you must be careful that maybe it do overwrite your PC's ACR default settings. For my LR, this was the case.
