View Full Version : New lens and camera for Real lens Camera properties

06-11-2009, 12:46 PM
I would like to know if it's possible to add new
camera or lens, in real Lens camera menus...

And I have another question : the "Frame" parameter in Camera properties is the horizontal value, vertical value or diagonal value ?

In LW Real Lens Camera, Camera and Lens profiles are
embedded, you can't add a new one.

A Camera+Lens profile is a set of three numbers
to match distorsion, there are calculated
through a photo-based calibration process.
This can be done by user, but this is not easy,
PTLens software is able to deliver such a, b and c
polynomial to their customers.

The 3rd party RadialShift Camera can take
these calibration set for fix or zoom lens,
even directly from a profile data text file,
here a comparaison between Real Lens and
RadialShift Cameras,

x32 and x64 version available for download here,

You can also read in Exif data from pictures, just set the Real Lens Camera type to "from image".

If your camera and lens is not actually in the list
EXIF metadata could not help, since it is writed
by the camera for current settings,
but distorsion parameters needed
for Real Lens or RadialShift camera are not
provided directly by the manufacturer.
