Lightroom: Export images at multiple resolutions in one go

I have discovered through experimentation that photos published to Facebook look best at 2048 pixels on the longest side (the maximum it supports) but images measuring 960 pixels on the longest side come a very close second so that's what I export at when Facebook.

I also publish the images on my own website, which uses SmugMug as a backend and is capable of automatically displaying delivering higher resolution photos (than Facebook) to the browser depending on the viewport size, so I export at 1400px resolution to strike a balance between filesize and image quality.

My problem is that it's not currently possible to export these two sets of images at the same time, I have to do them one after each other (because doing them in parallel is MORE than twice as slow due to LR's poor parallelisation of task execution), manually switching between different export resolutions and folders.

Instead, I would like to be able to pick two (or more) resolutions to export at, set (sticky) subfolder names for them (so that they end up in separate folders within the base export folder), and set LR to export all the images in one go. This would save me a huge amount of manual faffing around every time I export, and because LR would only have to fully render each image once (instead of twice as at present) it would dramatically reduce the total time taken to export both sets of images.

I realise that it should be possible to write a plugin to achieve this (and I'm looking into it) but surely exporting a set of images multiple times at varying resolutions is a fairly common use case (e.g. web/client DVD res and print ordering res for wedding photos) and it would therefore be of benefit to a significant proportion of the LR user base to make it worthwhile Adobe implementing it as a native feature?

Are you not using publish services for this?

That doesn't solve the problem because it still requires me to publish twice (and in doing so cause LR to churn through all the photos twice), and recently the publish services feature stopped working for reasons unknown, which is an entirely different issue of course.

I contacted Jeffrey Friedl, the well known developer of various invaluable Lightroom goodies - see http://regex.info/blog/lightroom-goodies - and he said that it's NOT currently possible to write a plugin to export to more than one resolution & service at the same time, so Adobe at least need to improve the API to make this possible.

Specifically, Jeffrey said:

"I'd need the ability to invoke an export via an export preset. The feature
request has been in their internal system for some time... [so] They know about it, and I'm sure they'd like to have it if there weren't
other more pressing features to attend to..."

So Adobe, please at the very least implement this API enhancement and ideally add multiple export resolutions/destinations to the LR native functionality!

Two things you may want to consider in the mean time:

ExportManager - will initiate multiple exports, one after the other (or in parallel). Re-renders each time, but at least you get it done with one click.

PreviewExporter - Exports from the preview cache for fastest export in the west (or east).

To prepare the files that my wedding clients require, I have to export three versions of every file: one is full resolution, the next is an A4 resolution, the final is a facebook size with a watermark.

Instead of clogging LR up with re-rendering files that have already been rendered (and this process has actually caused disk problems for me in the past - don't know why, but maybe something to do with RAID1?), please we have the option to export the same file with multiple presets?

So, it would basically allow you to queue up presets. Once it has rendered the file, it would run that file through the queue of presets and not move into the next until it has finished the queue.

This would massively speed up exporting and reduce the hit on my disks.

I need to do batch exports. Example:
1. Select a group of photos
2. Batch export :
a. Full Res TIF
b. Full Res JPG
c. Resized JPG

Each to their own directory

Ideas?

@Rob - Thanks, ExportManager helps a little but it's still a slow process thanks to the multiple renders.

@Phil & @apmadoc - Sounds we all have similar problems, and the ability to export multiple presets with a single render pass would be the solution that works for everyone.

Yep - export-manager saves clicks, not ticks (hmmm, catchy huh?)

However, preview-exporter does save ticks (no re-rendering) - suitable for quick jpegs at reduced size or quality. (not appropriate for max quality jpegs. - although the jpegs start out at max quality, you are always re-jpeging a jpeg, instead of re-rendering the raw).

Not disagreeing with the original request (quite the opposite in fact), just tryin' ta help...

Lightroom Image Export: Multiple Image Size exports at once

I often export my images in 2 or 3 different sizes: fullres, 4800px and 1920px (HD)
Right know it seems like LR is calculating all devopements AGAIN for each export wich seems to be an excessive workload.
It would be great if we could specify MULTIPLE Size and sharpening Outputs alltogether with one Export Task, thus LR could do all its develope calculations on one Image, keep the resulting image in memory and then resize, sharpen and output to the different output sizes from there.

Much like the outputs in AfterEffects where i can easyly specify multiple formats at once

when Time is critical I sometimes just export the Full Res JPGs out of LR and then use something like Xnview (http://www.xnview.com/) to generate the smaller versions.
But of course thats not the best way as it is a cumbersome workaround and its rendering new JPGs out of existing JPGs, potentially increasing artifacts.

Would be great if Adobe could find a solution to efficiently export multiple formats.

"Would be great if Adobe could find a solution to efficiently export multiple formats."

It's not difficult, LR has to generate a max-res image during export anyway and then resizes it to the target size - it's only the last stage that needs to be enhanced to support multiple target sizes.

The problem is that Adobe clearly isn't interested in implementing this suggestion/feature, which is fair enough as it's only had 5 likes since I posted the suggestion back in 2011.

Meanwhile, time has moved on and I now have 100Mb broadband so I now export at 2048 and upload that to both Facebook and my SmugMug site, so I no longer need the feature myself as originally requested, though I would like to have a second copy automatically exported at the same size into a different (ideally sub-) folder without my usual watermark.

Exporting actions:
I often send out files with High Res version and Screen Res versions. I have two presets that I have to do one, then the other. I think that Lightroom would benefit wholly if you were able to export to multiple locations and in multiple formats with a single preset.
So like I would have it make a folder (Job Name) and in that would contain (High Res), .tiffs for instance, and (Screen Res) that has jpegs. All with one click.

Aspect ratios need to be saveable to presets as well. Like others in this thread, I would have a one click/keyboard shortcut solution to export to a number of file sizes. I have tried Automator on the Mac but 1. it softens images off and 2. often just goes away and does nothing at all.

I've always been a big fan of Photoshop's Image Processor Pro script for this purpose, and would love to see something similar in LR. The biggest need/ example that I see for this in the field is commercial photographers that want to deliver a folder of low res sRGB JPEGs and a folder of full res, press ready CMYK TIFFs to a client. So expanding LR"s capability to export to a CMYK color space would be big too....

I'm only working with Lightroom since a few weeks. But since then I've run into so many limitations (small stuff, but extremely hampering the workflow) of this software were I can't understand how Adobe actually managed to keep it's business alive. All the Pros who use it daily must go mental.
This multiple export thing is also one of those issues. To run several presets one after the other is so time and energy wasting and ridiculously stupid that one just wants to smash his head against the wall. Even the Freeware Canon DPP software can do that.
The Xnview tip is really good. I know it since several years. It's batch processing is a real treat. Scaling, Watermarking, rotating etc. etc. at a very high speed with the newer MP version. Adobe, you can learn from that software a lot and also maybe start to listen to the users/costumers who actually pay you.

This reply was created from a merged topic originally titled Run a GROUP of export presets.

I find myself often needing to run 3-4 export presets from Lightroom for the same image. (e.g. one sized for blog posts to a specific folder, another for low-resolution, another for high resolution, another to Dropbox, etc.). I've been running each preset manually one after another.

It would be so helpful to be able to assign export presets to groups so that running a group would run the whole set of export presets.

I tried everything I could find and ended up with Rob Cole's Export Manager plugin for LR back in version 3. It still works in version 6, but you have to manually activate it through the plugin manager vevery time you restart LR 6, which unfortunately happens automatically every time I switch to another catalogue (also a thing that I don't get. Why can you not have two catalogues open at the same time as you can in almost any program?).
And while LR is rendering the export sets, it is wise not to touch it, because it can get confused and mix up your files. If you have a selection of files for export and initiate the export, it will not remember the selection of fies, when you deselect them to work on something else while LR renders in the background (I think that is called multitasking;-) ) If it was true multitasking though, you should be able to make a selection, initiate an export for that selection and then be able to work on another selection while rendering, right?
But maybe that is working with LR 6 now, I have not tested it, because the time it takes me to check if everything did render fine, would take me longer than letting LR just render everything and then go on working.

That doesn't sound like an ideal solution.

And yet, there are trolls on this forum who say that this isn’t important. Trolls who think that it is fine for paying clients to waste their time fiddling with various plugins and hacks to get something simple like this working. While Adobe sits on the sides and watches the fun.
