Make your adjustments in Lightroom first. This one is a bit overexposed in the highlights and needs a little bit more detail in the shadows. (Even if you plan to go for a high-contrast look using Exposure, it’s good to have a wide range of tones in the image for maximum editing leeway.) Then right click on the image to bring out the pop-up menu, and choose Edit In > Exposure 5. In the menu that appears next, choose Edit a Copy with Lightroom Adjustments, and, if necessary, adjust the Copy File Options according to your preference.
