I feel like I'm constantly hearing about new shortcuts in Lightroom that make my workflow increasingly painless. This is one that's been around for a while, but you have probably never used it. This short video is an easy to follow tutorial from photographer Matt Kosklowski about an exposure feature that will surely speed up your editing process.
When shooting with the bracket function on your camera you'll end up with three, five, or seven photos of varying exposures that you can then process into HDR. While in the "Develop" mode in Lightroom, you will be able to match the exposure using the Match Total Exposures tool (Shift+Ctrl+⌘+M for Mac). This is useful for toning down that overly HDR look while still utilizing the shadow relieving benefits.
I've also found this useful when batch editing a lifestyle or portrait shoot. It's great to focus on the tonal quality and color grading of an image first, then match exposures of a photo group from a single image using this tool. It's also amazing to find these helpful devices in Lightroom that speed up the editing process; technical hacks that lead to a better product. If you have some Lightroom shortcuts that help your work flow, please share them in the comments below!
