Bridge CC 2019 jpeg images pixelated

I use MacOs Mojave with a Mac Pro late 2013, 3.7GHz quad core processor, 32 GB memory and AMD Firepro D300 2GB graphics.  I updated both Bridge and Photoshop when the new software was first made available. 

Yesterday I tried to save some Tiff files as Jpegs so that i might export them via the internet.  This created a problem.

CR2 images developed in Photoshop ACR, saved as Tiff Smart Objects and viewed in Bridge look good.  However, when the Tiffs are then re-saved as Jpegs and viewed in Bridge the Jpegs are pixelated.  The same Tiffs re-saved as Tiffs or as PSD files look fine in Bridge.  When the pixelated file in Bridge is viewed at 100% it is pixelated for a short time and then looks ok.  Pixelation is only seen when the Jpeg file is viewed at the usual size in Bridge.  The extent of pixelation is not massive but sufficient to be objectionable.

I have:

  • uninstalled and reinstalled both Bridge and Photoshop
  • purged the relevant caches
  • deleted the folder -  Users/Thom/Library/Caches//Adobe/Bridge/Cache/v36
  • reset all my preferences for Bridge and Photoshop
  • enabled and disabled Photoshop/Preferences/Performance/Use Graphics Processor
  • flattened, converted from 16 bits to 8 bits and changed the colourspace to sRGB before saving theTiff as a Jpeg,

None of these actions was helpful and the problem remains. 

Jpegs which are pixelated in Bridge looks fine when viewed using Canon DP4 software.

The result of the same conversion from Tiff Smart Object to Jpeg file on my MacBook Pro with the same operating system and software looks fine on that computer in Bridge.

It is worth noting that from time to time the symbols in Bridge, for example in the Application Bar and at the bottom of the Content Panel, appear in a bright green/yellow fluorescent colour.

Comments would be much appreciated !

All best wishes

Abhishek,

Thanks for your response.   I have sent you a zipped folder via Apple Mail Drop which contains the .tiff image file and the .jpeg image file to which I referred in message 5 above.  Please let me know if there are any difficulties with the Mail Drop. Thanks again.

All best wishes

Thom.


Abhishek,

An update about my problem of pixelation on conversion of .Tiff files to .Jpeg files. 

  • this issue occurred on my Mac Pro desktop computer
  • on the Mac Pro it only occurred with Adobe Bridge files
  • it did not occur on my MacBook Pro 
  • you could not see any issue when I sent a pixelated file to you. 

Consequently, I  concluded that the problem must be associated with the software installed on my Mac Pro.  I again uninstalled/reinstalled Bridge and Photoshop and confirmed that these actions did not resolve the problem.  I also reinstalled the computer operating system Mojave and this did not resolve the problem.  So I speculated that the software issue must lie somewhere in the interface between Adobe and the operating system.

As a first step, I deleted the following files from the Macintosh HD:  /Users/Thom/Library/ApplicationSupport/Adobe/BridgeCC  and  /Users/Thom/Library/ApplicationSupport/Adobe/BridgeCC2019.

This did resolve the problem and I can now convert .Tiff files to .Jpeg files on the Mac Pro and they look good without any pixelation.

In case there were any other corrupt files in the Mac Pro, I then did a search for "Adobe" on the Macintosh HD and deleted all those associated files (thousands!) from the computer.  I  reinstalled the Adobe Creative Cloud along with Bridge and Photoshop to give a clean start and the system is now working fine.

Thanks again for your help.  I am really pleased that the problem is now fixed.

All best wishes

Thom.

I sometimes have issues with bridge updating the cache. So images look pixelated in bridge. I notice after i shut down than resatrt it usually starts to work.

This is a persistent issue which has has been resistant to cache emptying, restarting Bridge, replacing Bridge with a new copy and repeating the same with Photoshop.

This is an update to my earlier post on 28 November.  My problem still remains:  when Tiff files are Saved As Jpegs they become grainy and pixelated.  I have recently observed that this problem does not occur if the Tiff file is saved to Jpeg inside an Action which includes a Save As command at the end of the action. 

I also note that when the file is Saved As to Jpeg, the Save As Jpeg dialogue box shows a flashing black line alongside the slider for 'Small File ___________Large File' as shown in the attached screen shot.  This flashing black line should not be there.  The flashing line does not appear when the Save As command is generated within the Action.  This all seems bizarre.  Any observations appreciated.
