Sharpening Question
Do the effects of sharpening on an image as rendered when viewing at less than 100% mean anything at all? I ask because when I sharpen in either C1 or LR, the programs do show the effects of sharpening when viewing the entire image (ie, less than 100%). But when i then process the images as jpeg's and open them, they look totally different, in other words when comparing those jpeg's at less than 100% to the corresponding dng's at less than 100%. Specifically, the sharpened DNG's always look far sharper than their corresponding jpeg's when viewing at sizes less than 100%. But then when I open the DNG to 100% and the JPG to 100%, they look exactly the same. Why is this and is this normal? Thank you.

Question is: where do you view the final JPG?
Programs use different methods of scaling. This is why 100% should be the reference...
Photoshop doesn't display anything usefull at arbitrary zoom levels - it displays "correct" images at 12.5%, 25%, 50%, 100%.
PS CS4 has introduced OpenGL so that you can view at any size. Theoretically. But OpenGL in CS4 isn't up to the task by now... IMO.0 -
I view the jpeg's in either LR or in C1 Pro. lets say i'm viewing them in C1 Pro, is there any % level below 100% where I should be able to view both the dng and the jpeg and have them both display "correct"? Should LR display "correct" at the same %'s as CS4? Thank you! 0 -

so you want a JPG with lossy compression (who knows much much did you compress it ?) to be identical to the original data ?0 -
I processed the jpeg in both c1 and lr into the largest size file that the programs would all me to. i doesn't seem to have anything to do with that, in any event, since the files look the same at 100%. rather, it seems to have to do with the way the programs render the different file types at less than 100%, but that's what i don't understand. 0 -
Our studio has been experiencing an issue with 5.0.1 and 5.0.2 where the sharpening amount requested looks correct on the screen when you processed the file at 100% but when you process a file at a higher amount (ie. 250%) then the amount of sharpening is not there. We have tested this in 3.7.9 just for comparison and that works the way it should. So there are issues with the current version of C1. 0 -
Phillip,
The case you have submitted, along with the RAW file, does not display the error you have reported. The sharpening in Capture One 5, when processing to 100% or 250% is correct.0 -
This was not what we found. We have since the beginning of this incident become beta tester and it looks like this issue is fixed in 5.1 beta1. 0 -
Phillip,
Glad to hear the Beta has solved the issue for you.0
