About
ExportSnapshot is a Lightroom plug-in that creates a snapshot in the Develop module when you export a photo.
I export photos from Lightroom for upload to different services, and I found it useful to have a snapshot of the state the photo was in, so I can go back to it later.
For more information on Lightroom plug-ins, check the Lightroom SDK.
Usage
Lightroom requires plug-ins to be in folders with special extensions. For
ExportSnapshot, this means you need to place the Lua files in a folder called
ExportSnapshot.lrplugin
If you create this folder in one of the default locations Lightroom looks for
plug-ins, it should be picked up automatically. Otherwise you will have to
open the Plug-in Manager, click Add, and point Lightroom to where the folder
is (and remember, if the folder containing the Lua files does not have the
.lrplugin extension, Lightroom will not recognize it).
After ExportSnapshot is added to Lightroom, you should see it in the Post-Process Actions window of the Export dialog. When you insert it, it will show up as a section in the export settings, where you have options for disabling snapshots, and changing the name used for snapshots. These options are saved along with any presets you create.
This plug-in has not been tested with publish services.
