However, projection of specific images such as windows and logos has been impossible due to the pincushion distortion inherent in these wide angle lenses.
With Goboland's mastery of keystoning and predistortion of images, it is now possible to use these extremely wide angle profiles to project precise, 'corrected' images on a much larger scale and from much shorter throw distances, says the company.
Goboland has developed a system of pre-distorting gobo images to compensate for the pincushion effect, regardless of which manufacturer's lantern is used.
Each manufacturer's unit has its own unique distortion factor which Goboland has calculated and can apply to each artwork.
