In those cases the estimate of target distance might be incorrect. If using a reflective print make sure the lighting is not reflected instead of the target design, stick to a matt paper is usually a safer option if not sure.ĭownload the target image file by clicking FoCal Target – 600dpi PNG in PNG format or a vector version that can be scaled without loss of quality in PDF format FoCal Target – PDF either option will work.Ī target printed to A4 or US letter size works well for most situations, if you’re calibrating wide angle lenses at far distances you can print the target a little larger (or scale the image so the target design fills to the edge of the paper). Key thing is that the target design has good contrast when viewed from the camera position. Usually we suggest to avoid using glossy or semi-gloss paper, it can work ok but glossy paper can end up with reflections from the lighting rather than showing the actual high contrast black and white design. Once printed we suggest to mount the print on something stiff that won’t warp or deform over time (foam core or similar is good). We’ve tried a lot of different printing techniques and found for best results a standard inkjet printer set for high quality printing on matte heavyweight A4 or US letter sized paper works very well. The FoCal Target is an important part of how FoCal works, information for self-printing the target can be found below.
