Lightroom 3 release and to create profiles for my Pentax K-7.\u00a0 So I set up a small scene to photograph and used an AF540FGZ flash in wireless mode to light it.\u00a0 I increased the ISO from 200 to 6400 in one stop increments while adjusting the flash output.\u00a0 There was some variation in illumination however this is more of a preliminary test and I adjusted levels in Lightroom to somewhat compensate.\u00a0\u00a0 You can click on an individual thumbnail to see the full resolution jpeg generated through Lightroom, however the files are limited to 2Mb.<\/p>\n<p
