Lightroom: Image export - a Lightroom issue generally, not just to Photoshelter

Hello

I posted an issue that I had a few days ago, which is still persisting intermittently on some images (http://feedback.photoshop.com/photosh...)

I have now found that the problem ALSO happens with export DNG files to my hard drive - so it is not an issue with the Pact Software Photoshop plug-in (as suggested). It seems to be an issue with Lightroom itself - the adjustments that I have done to the images are NOT applied upon export either to Photoshelter or Hard Drive. Please see the images below:



Images ready for export using the 'Hard Drive Publish Service'



Images exported as seen in Finder - NO adjustments applied!

Any help would be most gratefully received

Thank you

Hello - further to the above, I have tried exporting the DNG files to my hard drive as jpegs and it works - BUT jpegs are no good to me!!! :-(!

Looking around the Adobe forums, it seems that this is an issue affecting several users over the past few months!

Are you setting your Export File Settings>Image Format: to Original?
if so, that is your problem.

Original sends a pristine copy of the "Original" to your destination.

If you insist upon sending DNG's make sure you either have "Autowrite XMP" turned on or that you select the image and hit CTRL/CMD S to save your edit settings to the DNG File before you send it.

Rikk - Thanks for that - tried it all and it still fails!... still getting un-adjusted files exported... Tried it to Photoshelter and to my Hard Drive, both failed to give me my DNGs with adjustments, just the original file.

In desperation...

I would expect that. Unless they are using the Lightroom or the ACR engine on their end to interpret the files, I would expect the original Tiff inside the DNG file would be the resultant view. It is only when Lightroom or ACR gets a hold of the saved image development metadata that a rendered version appears inside of the Adobe Application. The Tiff file inside stays unchanged.

If you want a rendered view with all your changes, you have to send a rendered file. IE, a Tiff, a JPEG, a PSD.

Since I don't use Photoshelter, I don't know what can be hoped to be gained by sending a DNG. Would not a Tiff serve better?

What is the purpose of uploading your raw (DNGs) data to Photoshelter? Is this archival storage so you can remove the files off your hard-drive or are you expecting people to look at them, there? DNGs contain raw data so it is up to whatever viewer program or website to produce an image, somehow.

Since Photoshelter isn't LR, it is possible that Photoshelter is showing the DNG preview embedded inside by LR at some point in the process, at least at Import. It is also possible that Photoshelter is providing some default rendering of DNGs by using a third-party open-source product that would have no idea about Adobe settings. Either way, the look of the DNG on Photoshelter isn't going to match LR, necessarily.

If Photoshelter is using the DNG preview rather than doing its own non-Adobe rendering, then you can explicitly update the DNG Preview with a command in LR:

Select your DNGs in LR
Library -> Metadata -> Update DNG Previews and Metadata

Update this preview for one of your DNGs and upload it to Photoshelter and see if the view on Photoshelter changes. That will answer the question whether Photoshelter is using the embedded preview or doing its own rendering.

Rick, Steve - thanks for your emails and ideas, however I may not have explained myself correctly.

Some files get uploaded to photoshelter or my hard drive with adjustments correctly, others don't - they get exported without any adjustments that I have applied in Lightroom (cropping, exposure, contrast, vignetting, sharpening, etc...). Previously, I have never had an issue with this in Lightroom with DNG files. It is not Photoshelter that is the issue, but straight forward exporting DNG files out of Lightroom.

Steve - thanks for the idea of 'Select your DNGs in LR
Library -> Metadata -> Update DNG Previews and Metadata' - I have tried this and it failed to export the DNG to my hard drive with adjustments made in Lightroom. The export was not done to Photoshelter, so we can remove Photoshelter from the equation on this issue.

I use Photoshelter for my website, providing archive and sale facilities/functions (my website is currently pretty much empty as I am revamping the site). The reason I use DNG is so that the image quality is there for clients - if they want jpegs, I can easily convert them over to that format.

I am not the only one suffering from this issue when I look at the Adobe Lightroom Forums, please find a couple of the threads that I have found:

It would seem to me there is a bug in the export function for DNG files in Lightroom, which appears to be intermittent; but affecting users.

Any suggestions or if you need more info - please let me know.

Many thanks.

Your usage of Photoshelter seems reasonable if your clients have Lightroom or Photoshop-something for creating JPGs from your DNGs, there.

The first thread you reference, above, has resetting the LR preferences file as the correct answer. Have you tried that? The second thread you reference seems to have no conclusion.
