Join Seán Duggan for an in-depth discussion in this video Using layer masks to combine different exposures, part of Enhancing Night and Low-Light Photos with Photoshop.
…Now we'll finish the rest of this composite using a combination of…blend modes and layer masks.…So before we continue,…I just want to draw your attention to one other aspect of this file.…If I turn off the summit 01 layer, just so…we're not seeing that, and then I turn off summit 02.…There seems to be a very…perceptible difference between summit_02 and summit_03 in terms of position.…
If I turn off summit_03, and then turn on and…off summit_02 again, those two layers, summit_02 and summit_04,.…Those look like they're lined up perfectly, but…there does seem to be a very, very slight difference between summit O2 and…summit O3, is that a problem?…Well, depending on what you need to do with the composite, it may be and…you might need to use the same technique I showed at the beginning of…this exercise to align that layer.…However, the method that we're going to use to blend these layers together,…we don't have to worry about that, because we're going to…rely on the same blend mode technique that we used earlier in this chapter.…
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
