7.7.36 Digital Camera/Lens Correction
Lens Correction can remove several types of distortion that may occur
when taking a picture:
- Lens distortions
- PhotoLine uses Lensfun to correct lens distortions. Please note that
Lensfun is only available in the 64-bit version of PhotoLine.
- PhotoLine always includes Lensfun's current lens data. If you still want
to install newer data yourself, you can copy it into a subfolder named
"lensfun" in the settings folder (see chapter 1.6). The next time
PhotoLine is restarted, this lens data will be used.
- In the Lensfun subdialog the information about the current image is
displayed when opening the dialog. If these are not correct, you can also
correct them. The camera value is for your information only and does
not have to be correct.
- Use the Vignette switch to automatically correct the vignetting in an
image. However, the image must be in a linear color space (i.e. in a color
space with a gamma value of 1.0). This applies e.g. to the background
image of a raw image, but not to common JPEG images. If the image has
no linear color space, you should switch off Vignette and correct the
vignetting via the Vignette subdialog.
- Perspective
- Allows you to correct a perspective distortion in a photo.
- Vignette
- With this subdialog you can add vignetting to an image or remove it.
- Chromatic Aberration
- Chromatic Aberration offers the same functionality as the filter of the
same name (chapter 7.7.38).
