If you are someone who frequently comes home with loads of related images that you edit in a similar fashion, it will save you a ton of time if you learn how to take advantage of Lightroom's batch-editing capabilities. This excellent video will show you everything you need to know to be up and running.
Coming to you from Aaron Nace with Phlearn, this great video will show you how you can make your post-processing work a lot more efficient by taking advantage of batch editing in Lightroom. For example, I photograph a lot of classical music concerts in the same hall, mostly from the same vantage point. By this point, I know exactly how I want my photos edited. After I make my selections, I quickly dial in my normal settings and apply them across the entire batch of normally about 200 images. From there, it just takes quick adjustments to crops, and the images are done. It saves me a ton of time. If you work in a genre that puts you in similar situations, you should definitely take the time to learn how it is done. Check out the video above for the full rundown from Nace.
