I took it upon myself this week to learn Adobe Lightroom after my co-workers told me how it could really speed up my work flow. I used Lightroom briefly in the past before but never really stuck with it because I felt too comfortable with Photoshop. Right now though I've got a rush job to finish and time is very tight so I needed to take some desperate measures in order to ensure that I finish in a timely manner. I went and downloaded the free trial and got to work. It took a bit of initial getting use to as I'm not just using Lighroom to simply edit photos, but the edits need to have the look I like to go after that I consistently achieve with Photoshop.
After a three days of editing on Lighroom I think I can safely say I've got the hang of it. I am by no means an Lighroom expert, but I'm comfortable enough to get what I'm after with it. I still use PS in conjunction with Lighroom as there are just some things that are much easier in PS. In Lighroom I can finish a standard edit in fewer actions as compared to PS with a very similar result. However I love Photoshop for when I really dig into an edit such as in the case for portraits or headshots. The process is like polishing a diamond for me.
This is a topic I'm sure I'll revisit in the future as I really need to push my efficiency and workflow, however I'll leave it at that for now.
