Join Seán Duggan for an in-depth discussion in this video Retouching airplane light trails, part of Enhancing Night and Low-Light Photos with Photoshop.
…One of the fixtures of the night sky are airplanes flying back and forth.…And of course, the problem with that when you're doing photographs of the night sky,…is that they leave their light trails all throughout your images.…So, let's take a look at a few ways that you might deal with these.…I'm going to zoom up to 100%.…I'll use the shortcut of Cmd+Opt+0 on Mac or Ctrl+Alt+0 on Windows.…And I have two airplane-like trails in this shot,…one more objectionable than the other.…And the first thing I'm going to do is I'm just going to make a copy layer of…the area in question.…
I'm not going to duplicate the entire layer.…I'm just going to get my Lasso tool and…I'm just going to drag a big lasso selection, roughly around that area.…I'm going to float that up to a new layer, using the shortcut of Cmd+J on a Mac or…Ctrl+J on Windows.…I'll double-click on that layer name, and rename the layer Retouching.…And I'm going to lock the position of the layer so…it does not get moved accidentally.…So that's this third icon in the Lock Icons at the top of the Layers panel.…
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
- Stacking layers and combining exposures
- Improving star photography
