Join Seán Duggan for an in-depth discussion in this video Applying a lens profile correction, part of Enhancing Night and Low-Light Photos with Photoshop.
…Both Adobe Camera Raw and Light Room have an excellent feature for…applying a lens distortion correction to an image,…based on the type of lens that you use to capture the photograph.…The software can tell what lens you used by the metadata recorded from the camera,…and the lens profile corrections can compensate for…optical distortions that are common with many types of lenses.…So we'll use this image of the hotel lobby to explore the lens corrections.…And before we get into that, I'm just going to correct the white balance really…quick, because it's such a strong color cast in here.…
I'm going to come up and get the white balance tool, and…I'll click on the white registration counter in the background there.…And that fixes that up pretty good.…We just slightly tweak that a bit, brighten it up a little bit, and…just increase the clarity which will help a little bit with contrast.…There we go.…That looks better.…All right.…So there's a couple of issues going on in this image.…The first is that the photograph is crooked.…
In this course, photographer and educator Seán Duggan explores a range of post-processing techniques aimed at expanding your creative options for night and low-light photography—and even "shooting" stars. He'll begin in Camera Raw for general enhancements (white balance, tonal and contrast adjustments, and noise reduction) and then turn to Photoshop to capitalize on its Merge to HDR feature, which can create spectacular high-dynamic-range images. Last, he includes techniques specifically for star photography: stacking layers to create star trails, removing and replacing blurry stars, and using luminosity masks on photos of the Milky Way.
