<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Salve a tutti<br><br>Does anybody know a GNU/Linux free program, able to correct photo radial lens distortion (pincushion, barrel, chromatic aberration ...)?<br><br>Some programs generally requires a big amount of manual steps (i.e. Hugin). Is there something more accurate, user friendly and automatic like RadCor?<br><br><a href="http://www.uni-koeln.de/%7Eal001/radcor.html">RadCor - A Program for correcting radial lens distortion and chromatic aberration</a><br><br>Lens distortion affects more or less every photo, and needs to be corrected in order to obtain accurate photomosaic.<br><br>I think a lens calibration tutorial would also be a practical wiki addition to complement the photomosaic tutorial. <br><br>Ricardo<br></td></tr></table><br>
