Photo Mate R2 1.7 introduces Auto-Lens Correction features.
Vignetting (light falloff at the borders of the image), Chromatic Aberration (Red/Cyan color-fringing) as well as Lens-Distortion can be corrected automatically.
When you open an image and Photo Mate says "Lens Profile found" (Tab Lens-Adjustments), you probably don't have to do anything. Your Lens is already supported.
Depending on your lens, some of the features (Vignetting/CA/Distortion) may not supported, though. In this case, you can still refer to this tutorial.
Case 1: Photo Mate says "Lens Profile not found"
There are 2 variants in this case:
a) The "i"-icon can be selected
Press on it, and see if you can find the lens you shot with in the list. If yes, please send us a raw-file and the actual lens-name of the lens you was using via mail.
Check this by using Photo Mate, open the image and go to Exif-Data. If you see your Lens information (just the Focal-Length is not enough!), contact us. Otherwise, check the Exif-Information from your raw-image with some external software. If there is no Lens-Information, you always have to select the Lens manually.
If not, read ahead at "Creating a new profile"
b) The "i"-icon can't be selected
In this case, Photo Mate could not find a camera-profile. In this case, we also need the raw-file and information about your camera (if you have some). Otherwise we'll look ourselfs online.
Case 2: Photo Mate says "Lens Profile found"
Then set the checkbox "Use Lens-Profile". See what parameters are supported. If you can see that some are missing (like Chromatic Aberration Red/Cyan sliders are still available or Vignetting options are still available) you can read ahead at "Creating a new profile"
In case your lens is currently not supported or some important corrections are missing, you can help us supporting your lens in a future release.
First, please go to wilson.bronger.org/lensfun_coverage.html and check if your lens or the corrections are really not supported. Otherwise please contact us first!
Since Photo Mate supports the Lensfun-DB data, you can use their tutorials to create profiles. Here are some links to the tutorials.
Create or Edit the XML-File
Put all the values together in a XML-File like described in the tutorials. If you edit a lens, we recommend you extend the current lens-profile and edit it.
Please also make sure that you add your camera's crop-factor. You can find it in the xml-files, simply search for your camera.
Send the XML-File
You've got two options:
- You can send it directly to the maintainers of the Lensfun-Project. See the information here: lensfun.sourceforge.net/calibration/
- If you mainly need the profile in Photo Mate and want to make sure that you've it already in the next version, send the profile directly to our support: #mail
Please, just use one of the options! If you send it to us, we'll forward it to the project, so you just need to send one mail.
