As you probably know, Iridient Developer is one of the best software to handle RAFs, allowing you to keep a lot more details than others.
But, it has several disadvantages:
1) It's a separate software (closer to Photoshop than Lightroom), so you need to change your workflow, and it doesn't offer a library or ranking system.
2) It is quite expensive, at $145.
3) It's color processing is not as powerfull as Lightroom or Photoshop.
To fill these gaps, the developer launched a smaller software, X-Transformer. It allows you to convert RAFs (X-Trans) to DNGs (Bayer) using the same processing engine as Iridient Developer, thus giving an unmatched level of detail.
With the right settings, it's easy to integrate it into Lightroom and be able to reprocess the RAFs to obtain a greater level of detail.
First, install X-Transformer. Open it and adjust these settings:
Those allow for greater detail retention, without too much sharpening or artifacts, while disabling noise reduction (because Lightroom is more efficient for this). Obviously, as each image is different, I invite you to modify it according to your needs.
Since the latest version (1.0), it has a much tighter integration with Lightroom, being able to use it as a plug-in on macOS or Windows. To install it, the only action needed is to go in the Help menu and select Install Lightroom Plug-in.
To use from Lightroom, you can select one or multiple pictures from the Library panel, and then from the File or Library menu, select Plug-in Extras -> Process Selected RAW(s) to DNG
The other notables features are also welcomed :
We now have the possibility to translate the Fujifilm's Film Simulation in Lightroom's Camera Profile, which gives us about the same colors in Lightroom as we would have with JPEGs straight out of the camera.
Also, we now have the possibility to traslate Star Ratings from the camera, into Lightroom's stars.
Furthermore, X-Transformer can now keep the original file date when converting a RAF to DNG, which Lightroom likes very much.
We can easily see the effect that the conversion has on the pictures, colours are much richer and we have more Dynamic Range.
Zoomed-in at 100%, we clearly see X-Transformer's detail retention :
(On the left, the DNG and the original RAF on the right.)
All you have to do is test!
In Lightroom, select a RAF picture and do Edit In > X-Transformer :
You will then have a window like this, just click on Edit.
Lightroom will now generate a low-quality TIF that will be sent to X-Transformer. Since the TIF is generated in the same location as the RAF and with the same name, it is easy for X-Transformer to find the RAF. After the transfer, X-Transformer will ask you this question:
X-Transformer will process the RAF and replace the TIF with the DNG. When Lightroom will read the TIF, it will actually read the DNG processed by X-Transformer.
Once the conversion is complete, return to Lightroom and you will see the TIF file that will have the look of a freshly imported RAF.
To sharpen this picture, apply this Preset. Adjust it to your taste :
The DNG is now arranged in standard RGB, it can be easily used in most processing software.
Moreover, because this DNG has it's pixels rearranged, it is much faster to read :
To the right, the DNG and on the left, the RAF.
