DPP Annoyance: Disappearing Thumbnail Preview When Saving Selection In Photoshop.

I'm using Digital Photo Professional 3.6.0.0 and Photoshop CS2, with working image files saved as TIF.

All TIFs show up as thumbnails in Digital Photo Professional, along with the CR2 files, as normal. But, if I save a selection when working on my TIF in Photoshop the thumbnail image in Digital Photo Professional disappears and gets replaced with a cross.

I find this extremely annoying as I like to see my edited images alongside the RAW images in DPP. Is there any way to circumvent this annoying behaviour? If not, is there a way to delete saved selections from a TIF file in Photoshop, so as to (hopefully) restore the thumbnail preview in DPP?

Thanks very much,

Mike

DPP is really overly sensitive to any changes made in the metadata by other applications. PS is probably changing the Exif and certainly the embedded thumbnail. Replacing it with an X is mild, I and a lot of other people have had DPP crash because of the presence of a file from another editor in the folder.

Okay, thanks. Looks as if I'll have to put up with the X then!

I noticed that even when duplicating the original TIF, then flattening it and doing a further edit, it won't restore the thumbnail for the image. It would be interesting to find out what data is changed, to see if it can be edited back to what it was.

I noticed that all of the large jpeg files of scanned photos were shown as an 'X' after I upgraded to DPP 3.7.2.0 The thumbnails were visible before I installed the newer version of DPP. I have quite a lot of old family photos that were scanned and I was wondering if there was anything I could do to get the thumbnails back. All of my raws and other jpgs show up fine.

ps. I just checked and I cannot open these files in DPP, but they work ok in CS3 and Corel Paint Shop Photo X2.

Which operating system? I have nearly the same set up as you. CS2 and the latest version of DPP. I'm on a MAC and don't have the red X's on my TIF's after I manipulate them.

I'm using a PC with XP Professional.

The TIFs thumbnails display correctly in every state except if I save a selection with the image in Photoshop. I previously thought I could restore the thumbnail by flattening the image and duplicating it (therefore losing the saved selection, or so I presumed), but that didn't work.

As Elie said above, something else regarding the image data has been changed that is carried through when flattening and duplicating the file.

Incidentally they aren't red Xs like you get with a broken image link, rather that it's just a blank grey thumbnail box with a thin black 'X' cross through it from corner to corner.

Wierd, I have a bunch of tif's in the same state as you. I don't know anything about Windows. I hope somebody who can help chimes in.

I'm not sure myself -- I rarely use tiffs and use Lightroom and Bridge for my main photo browsing so never paid much attention to how DPP or windows viewers handled anything but Raw and jpeg.

So, I first used Windows Explorer to browse folder with a few tiffs generated by Lightroom and saved by Photoshop and turned the thumbnail on (I have the Raw viewing utility for XP) and the thumbnails don't show. I can right-click them to open in Photoshop, but I can't double-click them and open them in the image viewer.

I then opened an image in Photoshop, flattened the layers (all my tiffs are 16 bit with layers), converted it to 8 bits and saved it as a new tiff -- still no thumbnails.

Then, I ran into something really strange -- when I opened DPP, not only did the "regular" layered tiffs not generate a thumbnail (as you observed -- just gray squares with an "X" across them -- but DPP failed to even "register" the gray-quared tiff that had been flattened and converted to 8 bits -- the program threw up an error message and forced a shut down. It repeated this until I deleted the file in Explorer.

So, beyond my confirming what you're saying, I can't say more -- I only recently installed DPP, never used an early version, and I actually don't use it (I installed it mostly for eveluation and for offering some input here on POTN). And, I rarely even go into Photoshop and leave at tiff behind so I don't have a lot to offer at this time.

Sorry...!

Sorry Tony, I didn't get an e-mail notification for your reply.

I have just worked out how to restore the thumbnail images for my particular problem! I was reading up on things to do with saving selections to see if I could find where they are saved and it turns out that they are saved in the Channels list (Window > Channels).

I tried deleting the channels that contained my saved selections and once they are deleted the thumbnails appear in DPP again!

So, that's solved my particular mystery! If you have any selections saved, you could try duplicating the file, then deleting the selections from Channels to see if that works.

Hey, thanks for updating us! You know it's funny, I brought up this problem in another thread just this evening and decided to do a little testing. I tried three approaches -- saving a layered tiff, saving a flattened tiff, and then saving a tiff where adjustments had only been made to the background image, all in 16 bits.

I never got a layered tiff to show up as a thumbnail, I always got a tiff with just the adjustments done on the background to show the thumbnail and open in the editor, and having the flattened image show thumbnails was hit-or-miss. I don't have a clue why. I'm working with CS3 and the latest version of DPP.

Oh well -- I may play around with it more some day...

I'm sure there's someone out there that knows the answer to this! Just in case you haven't tried all the latest tests with 8-bit images, maybe that's worth a try, if only to eliminate that as a possibility.

My only other suggestion would be to smash something up, like I usually do when things get to this stage.
