I know C1 you can get a demo mode from the past , pretty sure you can today. Not sure on Phocus, Leaf or Sinar software though have to check on there sites
Leaf Capture is free so there's no demo version. Some raw files are available on our website but not these "specialised" ones.
Our custom gain workflow/s might be combining the best of all worlds, with three main pluses:
1. The corrections are embedded into new raw files that can be archived and/ or converted in any 3rd party converter
2. Falloff (vignetting) correction can also be embedded into these new raw files
3. For tethered shooting there's a wizard that guides you how to create and load a custom gain file
Post shoot correction:
1. Shoot a gain file (using the supplied diffuser filter) at the beginning/ end of a sequence of shots. If you change the aperture and shift, shoot another gain file. The filter takes about 2 stops so you have to compensate by using longer exposure.
2. In Leaf Capture, select "Leaf MOS" as the processing format and press "settings":
Select the preferred method and type in the required fall-off correction.
3. Select the gain file and the images that need to be corrected and press "process"
This will create new copies of RAW files that are corrected and ready to go into any 3rd party converter or archiving (this applies to Moire reduction as well BTW).
Shooting tethered:
You can use the same workflow as above or you can use a wizard that will guide you through creating a custom gain file and loading it to the back:
Etc.etc. or you can load a file that was created/ stored before:
Here's a before/ after with 15% falloff correction:
Hope this helps, the whole process is described in the LeafCapture help guide
Good night from Copenhagen.
