Lightroom: Build thumbnails and full-size exports simultaneously

It would be great if Lightroom could string export presets together, to perform operations sequentially or simply to perform several processes on one image to produce several different outputs.

The first use I’d put to this functionality would be generating thumbnails of exported images right along-side the full-sized image — a common task when producing images to upload to a blog, for example.

Absent that kind of flexible functionality, here’s a nice solution for generating thumbnails of images and full-size exports at the same time. Use Jeffrey Friedl’s Run Any Command plugin in conjunction with mogrify: Just insert “run any command” to an existing export preset, and then add the following as the Command to Run (assumes you have LR2/Mogrify installed, which of course you do):

cp '{FILE}' '{NAME}'-small.JPG ~/Library/Application\ Support/Adobe/Lightroom/Plugins/LR2Mogrify.lrplugin/LRMogrify.extras/mogrify -resize 50% '{NAME}'-thumbnail.JPG

The command makes a copy of your original image (which is available to “run any command” plugin via the {FILE} token), with “-small” appended to the filename, and then uses mogrify to resize the copy to 50%. You can optionally adjust the percent to scale or add a “-quality” option to the mogrify command.

You could perform this command more cleanly, without the copy step, if you have ImageMagick installed independently of LR2/Mogrify: The full IM package includes the “convert” command, which allows for output to a new filename. Since I didn’t want to separately install ImageMagick, I just make a copy of the file and then invoke mogrify via the path to the plugin.

Presto! Instant thumbnails, appropriately named, to accompany your export. Pretty good stuff, made possible by the great work of Jeffrey Friedl. Check out all his lightroom goodies.

Relative sized borders in Lightroom 2

I’m sure the rest of you figured this out ages ago, but it was a new realization to me. In addition to supporting multiple, different borders per image, the LR2/Mogrify border options for Lightroom 2 allow for borders to be applied on three metrics: pixel size, percent of height, and percent of width. That allow, for example, for easy application of letterbox-style top and bottom borders without needing to pay any attention to the cropped dimension of your image.

The plugin default is in pixels; just switch to percent and you’re off. Something in the range of 10-12% of height seems to suit my eye pretty well.
