I start my editing by correcting white balance and removing vignette and gradients again. Editing Workflow Step 1: White Balance, Vignette and Gradients While you can do everything in Photoshop &Co., StarStax (free, Win/Linux/Mac OS X) will make the whole process a breeze.

In this article I discussed in detail how to photograph star trails. The main difference is that you will not try to freeze the stars in the sky, but rather enhance their movement. Star trail photography is not much different than nocturnal landscapes. The final image has better colours and more details and less noise than the original RAW file. It’s important not to push sharpening, clarity and contrast too far. I then import the stacked image into Lightroom and/or Photoshop for final tuning.

Saving the stacked sky can be useful if you have different series of images for the sky and the foreground.

You can now save the stacked image and the stacked sky as TIFF. This will separate the foreground from the sky, align all the stars to a reference frame and stack the resulting images together. The mask for the sky needs some improvement using the brush tool. You can refine the mask by painting in more sky or painting out selected background. All the areas of the image that are considered ‘sky’ will appear in blue. The dots are the alignment points the program will use to align all the images. Those dots will mostly be over the stars, but some will be at the horizon or in the foreground. tiffs, you will see some red dots are placed in the sky. To do that I use Starry Landscape Stacker.Īfter loading all the. Reducing luminosity gradient above the horizon with a radial filter.įinally, I synchronise all my images in Lightroom and export them as TIFF.

To fix vignetting, I boost the contrast to +100and use the vignette slider in the manual lens correction panel.įinally, I use local adjustment tools to reduce most of the luminosity gradients so the image is as flat as possible. When I am happy, I set the saturation and vibrance slides back to zero. With local adjustment tools, I tweak the white balance in the sky to have a more homogenous mixture of purple/green/yellow in the sky.

Next, I push the saturation and vibrance sliders to +100 to see the different colours in the sky. To fix the white balance I start with a general balance for the foreground using the eyedrop tool. I like to import my raw files into Lightroom to fix these issues first. This will cause all sorts of problems with white balance and luminosity gradients. One of the main problems when shooting starry landscapes is light pollution, particularly low on the horizon. Step 1: White Balance, Vignette and Gradients

Sony RX100 Mk ii on a tripod and set to ISO 6400, 15″, 28mm EFL (equivalent focal length), f/1.8. The sky was moderately polluted, scoring a 5 in the Bortle scale. Let’s work with this starry landscape I took in Cap-Blanc-Nez (Calais, France). Don’t bother trying to stack in Photoshop. It supports RAW files.įinally, you can use Adobe Photoshop/Lightroom to edit your stacked image.

Softwareĭedicated software such Pixinsight is great, but such software usually has a steep price and learning curve. For each case, I will focus on the key steps of the editing workflow. Since there is not a single workflow that will fit all cases, I will break down the subject in four case studies. Luckily, software is available to help you with the process. Image stacking consists of three steps: image calibration (optional), alignment and stacking. Don’t forget to take them at the same temperature as your light frames. While you are packing your stuff, take some dark frames. Whether you are after a starry landscape or a faint nebula, take as many images (light frames) you can of your target. The work for image stacking begins in the field. Stacking increases the signal-to-noise ratio, giving a cleaner and more detailed image. This is the only step that is central to editing any kind of astrophotography. Image stacking is the process to combine all your light and calibration frames into a single image.
