CaptureONE PRO 7.1.6 Image Discrepancies
Greetings and salutations,
I have a favor to ask users of C1PRO 7.1.6 and will you mind following these simple steps and let me know if you observe image discrepancies between the JPEG exported from Process Tab and the JPEG via the File >> Make Web Contact Sheet (MWCS) feature within C1PRO7.1.6. I recently reported a finding to P1 Tech Support and I want to know if others could acknowledge my findings to procure more data.
JPEG Process Recipe (PR): JPEG, 8-Bit; ICC Profile: sRGB IEC61966-2.1; Resolution: 72 PPI; Scale: Long Edge @ 1280 Pixels; Disable Sharpening Unchecked
Web Contact Sheet Settings (WCSS): This is going to be "relative" because we can't input numbers, I am using the eleven markings to best share my settings. These "markings" are little marks on the draggable scale (evenly-spaced) and you'll know what I mean. Thumbnail Size: 3.5 marking from the left; Preview Size: 3.5 marking from the left; Quality: 11 marking from the left (max value).
Using the settings, will you let me know if you could determine image quality discrepancies? The standard or basis image is the JPEG processed from the Process Tab using the aforementioned settings. I am thinking, there is something wonky going on with the Web Contact Sheet feature.
Method
1) Open Photoshop and open the JPEG exported from PR.
2) To open the JPEG from WCSS, you'll have to go into the folder you made for the MWCS. In that folder, you'll see: index.htm and three folders: photos, scripts, and theme. Go into "photos" >> "previews." You should see the single JPEG you are using to test image discrepancy. Open that JPEG into Photoshop.
3) Try to arrange the images in PS so they are shown adjacent to each other.
Questions
1) Do you see any image discrepancies?
2) Do you see an undesired artifacting fringes in the background? In my example, I am using a Thunder Grey and I have applied my style to color grade the image.
Assumptions
1) I am on a dual-monitor setup with both color-managed workflow: The GPU is outputting the differing LUT ICCv4 profiles to each of my monitors accordingly.
2) OpenCL settings for C1PRO7.1.6 is set to both "Auto."
3) Windows 8.1 PRO (latest and stable updates) have Color Management (CM) set properly and both the operating system CM and C1PRO CM is set to "Perceptual."
Data and Results: The two images were processed and procured using the settings above. Images are are 72 PPI @ sRGB @ 100% Quality. Left JPEG was process via PR and image on the right (with problems) is via MWCS.

Link 2 (Settings ZEROED): .
I am trying to make sense and understanding why I am observing the image discrepancies. I want to know if this is an isolated observation only for me or can similar discrepancies are seen by others?

The Web Contact Sheet uses slightly different settings then the Process Recipe.
The main one being that the resolution is predefined in the Web Contact Sheet settings, as is the colorspace.
The other settings for Quality are based on a JPEG compression algorithm that prioritizes speed and size so that the JPEG previews are applicable for web viewing and loading.
The Process Recipe for JPEG allows all aspects to be defined by you.
As such, the two process' are slightly different. Not enough that a noticeable difference at 72ppi would be prominent but different enough that if you pixel peep you may see a slight difference.
As a Web Contact sheet is seen as a "quick proofing" option and the limitations imposed by web viewing prevent the practicality of a fine quality final output, the overall difference seems extremely minimal.0 -
Hi Drew,
I am actually in the middle of trying to make sense of this in a case support ID: 138343. I sometimes use the MWCS to show to clients and assuming I see the artifacting fringes, they probably see it too. That is a concern for me. That is why I asked others who use the MWCS feature as a digital proof with their clients.
I am an ardent user of C1PRO and if version 8 releases tomorrow, I'd probably upgrade and HAPPILY pay the 99 USD (assuming that will be the same price). I brought this up because:
1) I wanted make sure I am not the only one.
2) If other users feel similar like me, it is cause for concern and should be addressed in a manner that is manageable.0
