Exported 16bit Tif Bug

[NN635763134542939057UL]

Curious if anyone else is experiencing this. Since the last update, when I process a file out as a 16 bit Tif, I can not open it within Preview. The thumbnail in Finder also doesn't display. That said, I can open the file in Photoshop fine and once I save it from there, it's then treated as a regular Tif file within OSX.

Anyone else?

It works as expected for me,opens perfectly in preview and there is a thumbnail in Finder. Sorry, but I can't think of any reason for your issue.

What version of OS X are you using?

Same here: TIFFs do not show any thumbnail, preview shows a black image

[tenmangu81]

Did you try to create a new variant for external edition, e.g. PS or SEP ?

@adrianchapman: Running the latest version of OSX and C1

@tenmangu81: Just tried an 8bit Tif of the same file and it works fine.

I'll submit a bug report.

I too am experiencing Black thumbnails on export with 16bit. Photo matrix Pro crashes when trying to load those files in its stand alone program. Not sure if related still testing.

A quick google search of 'can't open tif file on mac' or 'cant open 16 bit tiff on mac' reveals many folks with the same issue from many different programs.

There are many different suggestions as to what to try & test. I've also seen 'blank/black' previews on my system, however my current running beta ( 10.12 Sierra release 3) does not appear to have that issue.

If you'd like - tell me a process recipe & I'll give it a test on my iMac.

Hi all,
Just for your info : I am not sure C1 works well when using Sierra:

Hi everybody,

the support team send me a work around for that problem: I set tiling (any size) on in the recipe for the 16-bit TIFF and I'll get a thumbnail now. They said it must be a 10.11.6 issue with rendering 16-bit images.

The file size increases depending on the tiling setting. I have no clue what that means, but it works

Also, another command you can use to check your tif output ( aside from sips ) is tiffutil.

No clue on what most items are, but if you are 'staring/comparing' on different output files - and looking at whats different between 'works' & 'doesn't work' - you may see some difference.

sips: scriptable image processing system.
tiffutil: manipulate tiff files.

Both should be on you mac & available at command line.


cheers!

This is a bug with Apple's image core in 10.11.6 so it will show up when using Preview, quick look (file icons and preview in finder) and any other program using Apple's built in rendering. You will not see the same issue on Macs with 10.11.5.

Specifically 10.11.6 breaks compatibility with non-tiled 16-bit Tiff files with a dimension larger than 3000px on the short side.. smaller files will be OK.

The workaround solution is to change the options in Capture One. When you have selected Tiff as your process recipe format an options field appears below the format field. Click on it and select a Tile dimension of 128.

Is this related to any specific camera, Mac configuration, ratio, or anything else?
I am using 1DX raw files, 3456x5184 pixel, processed into 16bit TIFF (not tiled), and a MBPr 2014 with 10.11.6.
Finder thumbnails are available and Preview shows the processed image.


Regards,
Hans

Jon's fix above works perfectly.

I'm running OS 10.11.16 and Capture One 9.3 I was getting a black preview and blank icon in Finder.
Process Recipie>Options>Tile Dimension>128 (This fixed it.)

Thanks Joe!!
