Profiles for Cameras with Fixed Lenses
If an entry indicates JPEG: no distortion then no correction is necessary for JPEG images. This is because distortion is corrected in camera’s firmware and no calibration (or profile) is necessary. If the camera has the capability to shoot Raw images calibration will still be required as Raw images represent unprocessed sensor data. Calibrated profiles are based on images submitted by users.
With the advent of in-camera distortion correction some cameras are calibrated Raw only. These calibrations are suitable for raw converters that do not correct lens distortion.
