Hi johnrellis​ - thank you so much! This command was exactly the right one to replicate the feature of Exportant that I originally created this thread searching for. Your recommendation of Run Any Command in conjunction with Exiftool was spot on! ... View more

Hi trshaner, thanks so much for the detailed information with screenshots! I appreciate you taking so much time to investigate this with me. While I'm using a Mac (so don't have Exiftool GUI available to me) I've been experimenting with the information you and  johnrellis​​ provided in my other thread and almost have a solution working with command line Exiftool using the Run Any Command plugin! The information you posted here makes me even more confident that a solution with this plugin and Exiftool is possible. Would you mind taking a look there and letting me know if you have any ideas regarding either the Exiftool commands I have written, or their acceptance by Run Any Command? This would help greatly! ... View more

Wow johnrellis and trshaner - thank you!!! I've made some significant progress with this solution thanks to your posts. I'm running into one small issue, but I think I'm in the home stretch. Here's what I've done: Installed ExifTool from here (I'm on a Mac, so I followed those instructions). I confirmed that it was installed correctly by typing "exiftool" in the Terminal (it works). Installed the Run Any Command Lightroom plugin from here​ and installed it. It seems to be installed correctly in Lightroom. Inserted the following under "Command per image". This was the best I could do after half an hour or so of perusing Exiftool examples and documentation. I'm not sure if I can combine these into one command or not. exiftool -TagsFromFile {FullMasterFile} -XResolution {FILE}; exiftool -TagsFromFile {FullMasterFile} -YResolution {FILE}; exiftool -TagsFromFile {FullMasterFile} -ResolutionUnit {FILE}; Upon hitting Export, it fails with the following dialogue: Now, here's the strange part: if I take those "actual command line sent to the operating system" lines and put them into my Terminal one at a time in the same order... it works!!! This gives me the desired effect (the file in the Destination folder has the same print dimensions as the source file). I also tried combining these into one command (didn't work - I may have done it incorrectly) as well as giving Run Any Command just one of these to work with (XResolution didn't cause an error on its own though I'm not sure if it worked as the XResolution never changes, and ResolutionUnit did not work on its own). Do either of you guys know what Run Any Command's issue with this series of commands could be? I feel like this is so close to a final solution! ... View more

Hi everyone, thanks so much for your detailed explanations and information you've provided. I have another thread in this forum that some of you have also posted in, and am currently exploring the few options you uncovered to get Lightroom to do this (most of this exploring is pending responses! ). I'm feeling a little less optimistic now that this is possible, but am holding on to some hope. Please let me know if you think of anything additional that I could use to preserve the source image's print dimensions when exporting from Lightroom! ... View more

Hi trshaner, thanks for trying to help! It's a shame that you suggested this feature so many years ago and it hasn't been implemented. I suppose that means there's no hope of a first-party solution, but I'm still hoping I can find a plugin or workaround that will provide the same functionality - Lightroom is otherwise perfect for the workflow I'm exploring. Do you have the Exportant plugin yourself, or know where I can get a copy? From what I've read about the licensing on Rob's other plugins (such as the one now available here) encouraged reasonable sharing of them. ... View more

Hi johnrellis, thanks for the additional information. I took a look at the thread you linked and installed the plugin. Though it seems to be "Installed and running" according to LR's Plugin Manager, it does throw some strange errors on a regular basis. Do you know how I might use this plugin to achieve my goal of exporting images with their existing embedded print resolution? I saw a screenshot of Rob Cole's "Exportant" plugin that had this feature, but don't know if it's possible with this one ("rc Exif Meta"). I also spent some time perusing the documentation for Run Any Command and Exiftool. I understand the concept of "copy the source file's print information to the exported file, after it has been exported" but don't see how I can do that with these two. Where I'm stuck is what Exiftool calls this particular data - if you have any pointers here, I think this could give me enough information to experiment with these two tools! I'm a little confused by your third post in this thread - you mention that I just need to use Run Any Command to tell Exiftool to copy the resolution from my source image to the exported image, but the resolution doesn't change between them as-is. Lightroom insists on a "Pixels Per Inch" value that makes it export as a TIFF with different print dimensions, but the image in the same resolution. Does your advice about Run Any Command and Exiftool still apply? Thanks for all of your help with this, I really appreciate it! ... View more

Hi dj_paige, thanks for replying to this thread as well! Do you know of a way I can recreate just this feature (the ability to export from Lightroom using the same print resolution as the original source photo) without Rob's plugin? I'm happy to purchase a paid plugin that would do this as well. This would be a huge help - it's what I was trying to describe in the other thread! ... View more

Hi dj_pagie, thanks for the additional clarification. I apologize that I can't articulate this more clearly - let me give you a more specific example of what I'm trying to accomplish: I have an image that's 2475 pixels x 3575 pixels. In Photoshop, I can set this to 18" x 26" at 137.5 pixels per inch and save it as a TIFF. I can put this TIFF into any software that queues jobs for my large format printers, and they will correctly interpret it as 18" x 26" at 137.5 DPI/PPI. I need to perform some light editing on this image in Lightroom, and have it export as a TIFF that Photoshop (and my other software) still recognizes as 18" x 26" at 137.5 DPI/PPI. This whole time, the image hasn't changed from 2475px x 3575px. If I was just doing this with one image, it would be simple - I could change the PPI setting in Lightroom's Export dialog, or as you suggested I could tell my print software to take this digital image and print it at 18" x 26". But I need to do this with many hundreds of images, so I need the TIFF to be exported from Lightroom with this information preserved. Photoshop is able to do this without issue, but Lightroom insists on overriding the PPI setting from the source file with an arbitrary number that can't be set to default to the source's PPI. Does that give you any more information to work with? Also, I have written another message that is still being moderated, so I apologize to you if my replies seem incomplete. I did try to reply to both of you directly! ... View more

Thanks for your reply Jim! I believe I'm following you with regards to DPI not changing the quality of the image - it's the same number of pixels at 300 DPI as 100 DPI, they'll just print at different sizes. This is the crux of my issue though. I have many different files saved as TIFFs, all of which know the exact print size and DPI of the image contained in them, and the print size and DPI are different for every one. One may be 16" x 20" at 137 DPI, another might by 24" x 36" at 300 DPI. There are hundreds of these, all of which I need to export from Lightroom. Do you know of a way to do this, while preserving the DPI info contained in the file when it was imported into Lightroom? I can't set it manually for each one, and do one at a time. To elaborate further, I discovered that a plugin used to exist (no longer available) called Exportant by Rob Cole seems to have the feature I need. I wrote about it in my reply to dj_paige. Would you mind taking a look and seeing if you know of how I can accomplish this? Thanks in advance for any info you may have. A solution to this issue would help me a great deal. ... View more

Hi dj_paige, thanks for your quick reply! I'm referring to the "Resolution: ___ pixels per inch" in the File Settings section of the Export window. It's unfortunately not possible to disable this option - it's always there. What I want to do is start with one TIFF file that's 16" x 20" (regardless of resolution, regardless of PPI, I have multiple pieces of software including Photoshop that correctly interpret this file as 16" x 20") and let it be a 16" x 20" TIFF file after the export. I know I could set the PPI manually and have the result I want for this one file, but I need to do this for hundreds of files. All of them have different PPI values when printed at their intended sizes. A user named Rob Cole answered a similar question here: Lightroom 5: export isn't resizing exactly to specified long edge. | Photoshop Family Customer Community Unfortunately, he has since disappeared. He had a plugin called "Exportant" (I believe) that has a feature called "Maintain Original Resolution - Export (print) resolution to be the same as original source photo, regardless..." and then it cuts off. But it sounds like this is exactly what I want - I want the export PPI to be the same as the original photo, regardless of anything else. Do you know of any way to accomplish this? Thank you in advance for anything you can think of. ... View more
