I am in the process of determining which darkroom software to buy and though I am leaning toward LightRoom there seems to be something about LightZone that looks interesting. I plan on being a moderately light user (work time constraints) and do not want something too complicated or with a steep learning curve. I am an old (20+ years ago) medium and large format BW amateur shooter who would like to get back into things now that the kids are grown. Recommendations? Thanks!
