Today's cameras do a great job of capturing low-light and nighttime scenes, but there's always room for improvement—from basic processes like noise reduction and tonal adjustment, to advanced techniques, such as combining different exposures. 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.

Topics include:

* Using neutral guides to set white balance

* Applying lens profile corrections

* Reducing noise

* Working with 16-bit and 32-bit HDR images

* Stacking layers and combining exposures

* Improving star photography
