Export in 2 pages tiff even wo embedded thumbnails option

chandres
Hi,
I have a serious problem during export in tiff. The file have always an embedded thumbnails even if I uncheck the box for generating thumbnail image in the process recipe. I check with several outpout option and raw file from Sony A900 and Nikon D800E, and it's always the same.

I have 40 000 pictures to upload on Wikimedia Commons and I cannot open all in photoshop just to remove the thumbnails.

Thanks to anyone who could Help!

    Can you help me to understand your problem better by describing how you view the embedded thumbnail and how you remove it?

    Thanks, please find here more information:
    My actual workflow is:
    * image capture in raw format either with a A900 either a D800E
    * Batch treatment in Capture One 7 for White balance, lens correction, metadata modification
    * Export in TIFF with C1 parameter: 16 bits, no compression, no embedded thumbnails, camera ICC
    *Batch upload on Wikimedia Commons

    The embedded thumbnails is problematic because it result on a two pages files on Commons, see an example here http://commons.wikimedia.org/wiki/File: ... 002959.tif

    I can remove manually the thumbnail by opening/saving in Photoshop, but not by the script method, don't know why it's working only file by file (the script method save two different files the main one and the thumbnails) an example of manual correction http://commons.wikimedia.org/wiki/File: ... 001946.tif

    I think the problem is coming from C1 because I can do the same workflow with Aperture and having no problem at the end. My problem is that C1 give better result for the treatment than Aperture.

    thanks a lot for your time

    Is this really a problem at Wikimedia?

    As I interpret the results from one upload you have delivered a full resolution file and a thumbnail. No further processing required. Wikimedia users can choose which of the two files to present for their purposes and, presumably, if they choose the small thumbnail there would still be some internal connection to the larger detailed version.

    I may be missing a point but I can see some benefits with what actually happens with your current workflow.

    Hello SFA,
    it's problematic because it really doesn't look like "professional" work, for thousands of pictures it's really bad.

    Every tiff I upload without using C1 still have the thumbnail embedded, but do not act as a two pages tiff.

    it's also useless because you cannot download directly the thumbnail, if you click on the 2nd page, the thumbnail you will in fact download the full file. Also Mediawiki offers to the user the possibility to download smaller jpg version of the full resolution file (just below the picture you can see the 4 available resolution).

    I would really like to be able to avoid having to do a second treatment in another software just to remove the thumbnail. ☹️

    I find a capture of the option that do not work properly http://www.phaseone.com/Search/Article. ... nguageid=1 it's the "create thumbnails on save", check or not check the thumbnails is created in my case.

    May I also ask to get a solution to that pretty annoyous problem?

    Hello,

    I am also having this problem with multi-page tiffs generated from CapturePro 7 with the thumbnail option turned off.

    We are capturing hundreds of images every day with our PhaseOne camera and sending tiff images through post processing to generate a jpg for access. Our software is generating two images per tiff, the normal hi-res image and a lower resolution image 160x120. It is quite annoying to go through and delete the second jpg.

    I have run the images through the tiff library using "tiffinfo" on the command line and for all tiff images produced from CaptureOne 7, regardless if you check or uncheck the thumbnail option I get the following additional tiff offset.

    TIFF Directory at offset 0xad0a9fc (181447164)
    Subfile Type: reduced-resolution image (1 = 0x1)
    Image Width: 160 Image Length: 120
    Bits/Sample: 8
    Compression Scheme: None

    JHOVE also reports: NewSubfileType: reduced-resolution image of another image in this file

    Opening with Photoshop doesn't give any hints there is a second image, but opening with Gimp or Ifranview on the PC you can see there are two images, they are multi-page tiff's.
