The processed file has likely been re-imported, but you won't see it if the Lightroom Filmstrip is set to 'Previous Import' (which Lightroom sets this way after you import images from your camera).
If 'Previous Import' shows above the Filmstrip, right-click on it and select All Photographs instead.
If you want to avoid seeing your entire catalog after choosing 'All Photographs', right-click on one of the source images and choose 'Go to Folder in Library.'
If you don't see a 'Plug-in Extras' item on Lightroom's File menu (nor an 'Export' item on the contextual menu), it's likely because you are using 'Lightroom CC'.
Lightroom CC is basically the mobile version of Lightroom, and this doesn't support plugins. So, you will have to use the application that is now called 'Lightroom Classic CC' instead.
Adobe's Creative Cloud Photography plan includes both the 'Classic CC' and 'CC' variants of Lightroom normally, so you should just have to download the 'Classic CC' variant on your computer.
This requires downloading and installing Photomatix Pro as detailed in the installation instructions for the plugin.
If the "Export to Photomatix Pro..." item does not show under "File > Plug-in Extras", this could be due to an installation issue or because Lightroom is looking for plugins somewhere other than where you installed it. The latter could happen if Lightroom was installed by a different user account than the one used to install Photomatix Pro for example, but might also depend on other factors specific to your Lightroom installation.
You can solve the issue by following these steps to install the plugin manually:
macOS X: Photomatix.lrplugin zip file for Mac
and unzip the downloaded file if not done automatically.
If you are using Photomatix Pro version 5, then download the older Plugin version here.
This error message is normally returned when the location of the photos you selected in Lightroom for export has changed since the time you added these photos to your library.
So, please check whether you had not moved the files of the photos you tried to export. If this is the case, then remove the photos from your Lightroom library and re-import them again. The export to Photomatix Pro will then work normally.
The Export to Photomatix Pro plugin can only be used to process a single set of bracketed photos in the Photomatix Pro interface.
To use Photomatix Pro to batch photos from Lightroom, you'll have to export the photos as TIFF to a folder on your computer. Then, run Photomatix Pro's batch to process the folder where you exported the photos.
Another option is to use the Photomatix HDR Batch Plugin for Lightroom instead. This is a plugin separate from Photomatix Pro that batch processes photos with HDR directly inside Lightroom.
To use a color space other than the default Adobe RGB color space, please proceed as follows:
The Photomatix Plugin's dialog will then show. The Plugin will export in the color space you have specified on the Export dialog in step 3.
You can grant Photomatix Pro the permission to reimport to Lightroom by following these steps:
Yes, the Lightroom Plugin included in the current version of Photomatix Pro works fine in Lightroom CC and Lightroom 6.
The installation location of plug-ins did not change between Lightroom 5 and Lightroom CC / 6, which means you should not need to do anything to have the Photomatix Plugin work in Lightroom CC / 6.
Note, though, that if you uninstalled Lightroom 5 and this resulted in removing your Lightroom Plug-ins folder, then you would need to re-install the Photomatix Plugin in this case. The installation instructions are detailed here.
The TIFF files exported by Lightroom to Photomatix Pro are temporary files. They are saved under a folder of your temporary directory, and then deleted by Photomatix Pro once it has processed them.
The default conversion of a raw file to DNG does not change the "raw" nature of the file. For Photomatix, a DNG file is still a raw file, and Photomatix will need to convert it before HDR processing.
The RAW conversion in Photomatix is slower and much less sophisticated than the conversion/rendering done in Lightroom. This is why it is better to have Lightroom convert the DNG files to TIFF when exporting to Photomatix rather than letting Photomatix do the conversion itself. In fact, the main benefit of using the Photomatix Plugin for Lightroom is precisely the ability to have Lightroom automatically convert the raw/dng files to TIFF prior to processing in Photomatix.
Yes, the Photomatix Plugin for Lightroom works fine in Lightroom run in 64-bit mode.
The current version of the Plugin is supposed to work in Lightroom 1.3 and 1.4, but with the automatic reimport option disabled as this only works with Lightroom 2.
However, there is a bug in the plug-in that makes it fail to export files in Lightroom 1. We will fix this bug in a further version of the plug-in. In the meantime, you can use the older version of our Lightroom Export plug-in which works fine in Lightroom 1.3 and 1.4. The download and installation instructions for it are below:
Move the folder Photomatix.lrplugin to the following directory depending on your platform:
C:\Program Files\Adobe\Adobe Photoshop Lightroom 1.3
C:\Program Files\Adobe\Adobe Photoshop Lightroom 1.4
Mac OS X:
The simplest way is to just download and install Photomatix Pro for Windows again, making sure that the box "Yes, install the Lightroom Plugin" is checked during the installation process.
Re-installing Photomatix Pro will do no harm, but we still recommend that you first uninstall Photomatix Pro (by using the control panel) before installing again. Note that you will have to close Photomatix in case it is open when you are re-installing it, otherwise the installation will report an error.
If you prefer to install the Plugin alone, then you can do this by installing the Plugin manually.
