I guess my point was missed.....................if you are going to invest the time to learn something new, why not learn the state-of-the-art? That's Lightroom!
Lightroom costs about $100, maybe less on sale. Why look for freeware, or something someone says "is just like Lightroom"? If you are in this hobby seriously, you are spending some money over the course of a year, so why look for shortcuts?
abmj is correct; don't invest time learning an off-brand..................Lightroom will be around the rest of your life, so get on-board............and no, I'm not associated with Adobe....
