Hi Alan, I am not a Lightroom user (I've had each new version for years but never used it, same with iPhoto, etc.). More of a Photoshop guy but I'm enjoying these standalone all-inclusive editors many of the major and minor developers are now releasing.
Do you have Lightroom? If so, download the
free Topaz Studio and try the basic AI Clear and compare whatever it is you're curious about.
If not, tell the others specifically what Lightroom features interest you so they can compare.
