Acolens is based on the parameters of individual lenses and corrects optical image deficiencies such as distorsions, vignetting and focus fall-off toward the edges. The new demo version already includes features that will shortly be available for existing users with their next free update of the software. Among those features is a semi-automatic assignment of lens profiles, the opportunity of adjusting the size proportions between the light table and the preview and a rotabable gridlock that allows for easier assessment of the distortion correction of non-horizontal takings.
