Join Seán Duggan for an in-depth discussion in this video Replacing blurry stars, part of Enhancing Night and Low-Light Photos with Photoshop.
- Sometimes no matter how hard you try,…to make an image where everything falls into place,…one of those components just doesn't…really fall into place where it should.…And you end up with something…that really compromises the effectiveness of the image.…So, such is the case with this photograph…of the auroras in Iceland.…If we zoom up close to this,…we can see that it is slightly out of focus.…It's a good pictures of the auroras,…but the stars are out of focus.…So what we're going to do in this project,…is we're going to remove these out-of-focus stars…from the night sky, we're going to leave the auroras…in place and we're going to add some…properly focused stars back into the sky…to salvage this image and end up with a good version…that is a nice representation of a great trip to Iceland.…
The idea for this project came about…due to a question from one of my consulting clients…who had this problem with some of their…own photos of the Northern Lights.…So I found one of my own images…that had a similar problem…
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.
- Using neutral guides to set white balance
- Applying lens profile corrections
- Reducing noise
- Working with 16-bit and 32-bit HDR images
