Lightroom is a deceptively complex program with a wide variety of settings that can impact both your workflow and the quality of your images. This excellent video details some lesser-known settings in the application that you should nonetheless be aware of.
Coming to you from Anthony Morganti, this great video goes over some important settings in Lightroom that you should be aware of. Some of these options can make your workflow more efficient, and it is worth taking the time to go into your preferences panel to set up the application to your preferences and needs. One option that made my workflow a lot easier was setting up Lightroom to generate 1:1 previews upon import. I frequently zoom to 100% to check that I have nailed focus, especially for things like wide-aperture portraits, and waiting the extra few seconds for the image to render can be annoying and really starts to add up time-wise when working with hundreds of shots. Using the 100% previews takes more space (so I'm sure to have Lightroom disregard them after 30 days) and adds more time to the import process, but I just do something else while the previews are rendering. Check out the video above for the full rundown from Morganti.
