I have a client who has me upload photos to their server via their proprietary web reporting app. Since I started using LR-CC my uploaded photos are degraded even though I'm using the same export preset that I used without issue in LR5, and even though the photos when viewed on my hard drive look fine.
The workflow is that I take photos, edit them in Lightroom, extract JPGs to my hard drive, and then upload the JPGs to the client's server using the client's custom web reporting app.
In the past (using LR5) I set up a custom export preset named for the client. The photos were for web use only, so I defined the preset for 640 pixels on the long axis, 72 ppi, screen sharpening. Worked great for many months. Client was happy, so I was happy.
When I switched to LR-CC a couple of weeks ago, I was pleased to see that my pre-existing export preset showed up in LR-CC. There were a few additional options available for exports in LR-CC but they don't seem relevant to the issue of extracting individual JPGs for this client. I have even tried opening LR5 and LR-CC at the same time and comparing the export preset line-by-line to make sure nothing's different.
The JPGs exported in LR5 and LR-CC both look fine if I examine them on my hard drive using any jpg viewer. When I upload any LR5 JPG via my client's web app, the photos look great in the client's reports. When I upload any JPG exported from LR-CC, however, the photo that looked fine on my hard drive looks very fuzzy, as if I had purposely defocused my camera. This is true even though the LR-CC photo looks perfect on my hard drive when viewed with any photo app.
I've gone back to the LR-CC export dialog and tried changing output resolution (I went all the way up to a 23MB jpg), and tried increasing JPG quality from the default value of 60. I've tried using a different camera. I've tried switching web browsers from Safari to Firefox. None of this affects the problem. Every jpg exported from LR-CC looks awful in the client report. Changing from LR-CC back to LR5 makes the problem go away. Every jpg uploaded from LR5 looks great, even at modest resolutions. The picture degradation happens on every uploaded photo that was extracted from LR-CC, but on no photo that was extracted from LR5. The jpgs from LR5 and LR-CC both look fine on my computer. From the standpoint of the client's web report, LR5 works, LR-CC fails. Yet the photos seem identical on my hard drive before I upload them (indistinguishable, in fact).
I have no details on how the client's web app uploads photos, and the client doesn't know anything about their software and has no tech support department. Their report software asks me to point to the photo and double-click on it so I presume it's some sort of file transfer protocol to move the JPG from my hard drive to their server.
My system is Mac OS 10.10.3 (Yosemite). I have tried using both Safari 8.0.6 and Firefox 37.0.2 with no difference. Can anyone suggest a resolution to the problem other than maintaining service to this one client using LR5?
