You can handle Lightroom!!! It's not that difficult, and there are plenty of good tutorials on how to use the adjustment brushes to be found on YouTube. Lightroom is really a good way to "handle" images...it has a few quirks, yes, but it really is pretty simple, and it makes life soooooo much easier for me. The problems with Photoshop and with Elements stem from the fact that BOTH were invented way BEFORE digital cameras were popular. The entire concept of how photographs would be edited was layed down in Photoshop back when a "scan" was a $100 thing, made by "a lab", and one, or two images per day or per week! would be worked on extensively, laboriously, one-at-a-time. The entire pixel-level, layered,laborious,resource-intensive, memory-hog program, the one-app-at-a-time concept is the era that Photoshop was created in, and it never made much progress, since that is what it is supposed to be.
Lightroom was developed only AFTER digital photography became popular, and it was developed because a BETTER WAY to handle photos was invented by Apple Computer, in 2005. That better way was called Aperture. It took Adobe a mad, two-year scramble to cobble together an answer, and they did it because for the first time ever, Adobe was faced with a competing product from a deep-pockets corporation that they could not ignore or buy out and bury. A big dog, Apple, had entered Adobe's monopolistic yard, so Adobe simply was FORCED to make a better product, one designed fresh, and in the actual digital era.
You WANT to have Lightroom. I disagree with his use of the term "professional". He's using the word in a weird way. I would say Lightroom is designed for modern photographers shooting with digital cameras. It is designed as a NEW method for dealing with lots of images; Photoshop once again, was meant for editing all types of scanned image data, in the era BEFORE most people even had access to a digital camera. Lightroom is from the start of the smartphone era; Photoshop's origins are from the phone booth and answering machine era.
