Lightroom Plugin

Welcome to the download page and mini-guide for using the Photosmith plugin for Lightroom!

You’ll of course need the app itself, available from the App Store here.


To get started, you’ll need to download and install the actual plugin. This part is pretty easy- just click the link below, and save the file onto your computer.

Download the Lightroom Plugin here

This zip file will contain a folder called Photosmith.lrplugin, which contains about 35 files.


The Photosmith Lightroom plug-in will need to be copied from where you downloaded it to the proper Lightroom plug-ins folder.  While the files are the same, the installation method differs slightly between Mac and Windows:


  • Uncompress the zip file and copy the files, directory and all, to a directory with appropriate permissions, typically:
  • Alternatively, copy to the Lightroom main directory and Lightroom will automatically recognize the new plugin upon startup:
    C:\Program Files\Adobe\Adobe Photoshop Lightroom 4.4
  • Note that if you choose any directory other than the C:\Users directory in Windows 7+, you’ll need to allow Administrator Privileges for psahttp.exe
  • Start Lightroom, and select File -> Plug-in Manager…
  • In the lower  left corner, click Add, and choose the Photosmith.lrplugin directory.

Mac OS-X:

  • Safari usually identifies the plugin directly – there is no need to unzip the file.
  • Simply copy the Photosmith.lrplugin to any folder of your choice. The recommended directory is:
    ~/Library/Application Support/Adobe/Lightroom/Plugins/
  • Start Lightroom, and select File -> Plug-in Manager…
  • In the lower  left corner, click Add, and choose the Photosmith.lrplugin module.

Once installed correctly, you’ll see Photosmith setup as a new plugin within Plugin Manager:

Plugin Operation

The plugin should show up at this point in the Lightroom Plugin Manager as “Installed and Running”. If it is marked as Disabled, then select the Photosmith plugin and scroll down to Enable / Disable and click “Enable”

Setup a Publish Service

To set up a Lightroom Publish Service for Photosmith:

    • Make sure the Photosmith Sync with Lightroom plug-in is installed and running.  You can check by selecting File > Plug-in Manager… then looking for the Photosmith plugin.  If it’s listed and has a green circle, you’re in good shape.

    • In the Lightroom Library module, find the Photosmith plug-in within Publish Services, and click Set Up… If you have trouble finding the Publish Services section, it’s near the bottom of the left-hand column.

  • You will now receive a prompt to “Save changes to this “Photosmith” publish connection” — click Save.

At this point, you are presented with quite a few options.  Let’s tackle them one-by-one:

  • Description - Choose a name for your Publish Service and type it here.
  • Device - Should automatically populate with information from your iPad. If your iPad wasn’t found, make sure it’s turned on and connected to the same local area network (LAN) via Wi-Fi as your Mac or PC running Lightroom, and that Photosmith is running in the foreground. Click the search button if you had to reset your iPad.

  • Lightroom -> Photosmith Image Options - You can choose to sync JPG files of your photos from Lightroom to your iPad, based on specific resolution:
    • Full Screen (1024×768) - for iPad 1 and iPad 2. This size resolution is enough to fill the iPad’s screen. They’re small, and don’t take up too much space, but you won’t have any ability to zoom. This is good for large photo sets and slideshows.
    • Full Screen Retina (2048×1536) - for iPad 3. Same as the above, but for the new iPad 3 which has double the available resolution.
    • Full Resolution - The full resolution of your photos as they appear in Lightroom, but as a compressed JPG.

    All JPG photos sent from Lightroom to Photosmith are in sRGB colorspace, to match the iPad’s internal color rendering. The iPad isn’t color managed, so this is a best-case fit. It shouldn’t be a big deal as Photosmith isn’t a color grading tool, and rating images shouldn’t be based on color, since it can be fixed in Lightroom because you shot in camera raw. You did shoot as camera raw, right? :)

  • Photosmith -> Lightroom Image Options - Here you may choose to apply a specific Lightroom develop preset for all photos transferred from your iPad to Lightroom during a sync. You may also apply a specific Lightroom metadata template, and choose how you want to handle collisions should metadata conflicts between Photosmith and Lightroom occur.
  • Local Destination - This is the location where your photos will be saved on your Mac or PC when they’re synced from Photosmith on your iPad. You can choose a template of several popular date-based folder structures.
  • Sync Options - You may choose how you want to handle existing keywords in Lightroom: Sync only keywords assigned to photos in the selected collection (faster) or Sync all catalog keywords with Photosmith on each sync (slower, but more complete).
