We used a bungee cord to tie our bag to the tripod to stabilise it in the windy conditions. When shooting long exposures, keep the camera as still as possible. Anything you can do to steady the camera is a good thing. A bungee cord takes up little space and is worth throwing in your bag. If there are distant lights, focus on these, then recompose. If not, get a friend to stand 40 to 50 feet in front of the camera and point a light towards you, focus on the light, then recompose.
Keep your lens warm to prevent it misting up as the night gets colder. We wrapped our lens with a heated hand warmer and a small towel, with a rubber band to hold it around the barrel. Be careful not to knock the focus ring when wrapping your flannel around the lens barrel though. Set your lens to its widest aperture. Set a shutter speed of between 20 and 30 seconds at ISO and take a test shot. If your shots are too dark, increase the ISO.
Change your white balance to Tungsten. This will remove the orange cast made by any nearby light pollution. Take a shot and check the histogram: This should allow your sensor to capture more detail. You can correct the exposure in post-production. The number will depend on how long you want your trails. We set shots at an exposure time of 30 seconds each. Go to the Develop module, and in the Detail panel at the bottom-right of screen — you may have to scroll down , under Reset Noise Reduction move the Luminance slider up until the noise is acceptable.
Name your catalogue Star Trails and click on Save. The empty Library window will open up. Click on the import button in the window that appears. Move to the Develop module. Starting from the top, switch the white balance to Tungsten, to alleviate the light pollution. Add fill light to brighten the midtones, and then increase the vibrance to boost the colours without clipping them.
Tick Check all before clicking on Synchronise, and these adjustments will be applied to all the selected images. The images open on separate layers. Drag the first image you took to the bottom and set blending mode to normal.
How to Capture Fantastic Star Trail Shots
You can fit more images on a card using the JPEG format, but it comes with quite a few trade-offs. RAW format actually saves the exact image — what the sensor sees through the lens — onto a memory card. Of course, RAW images take up more space on a memory card, but this can easily be countered by shooting with larger cards. The real advantage to shooting RAW is an extra one to two stops of exposure latitude. The aperture value Av refers to the size of the lens opening, which determines how much light makes it through the lens. Since aperture values or f-stops are represented as fractions, the smaller values actually provide a larger lens opening — and a larger lens opening means more light will pass through the lens.
This shutter opens and closes based on the settings you choose and ultimately determines how long the image sensor will be exposed to the light coming in through the lens. A slower shutter speed allows more light to reach the image sensor great for night photography , while a faster shutter speed allows less light to reach the image sensor great for controlling too much light on a bright sunny afternoon.
Street lights, car headlights, and even a full moon may prove too bright for a slow exposure, and may ruin your attempt at capturing the night sky. The ISO value is the digital equivalent of film speed.

Not only have cameras become cleaner at higher ISO settings, software tools such as Adobe Lightroom allow you to clean up images even further. Any higher and noise really becomes a problem.
When shooting the night sky, focusing becomes a greater challenge. A trick to focusing on the night sky is to aim the camera at whatever the brightest star is at that time, use the Live View zoom and magnify feature to make this object larger, and then turn the focus ring until the star looks sharp.
Now you can re-compose your shot, being careful not to touch the focus ring. But ultimately I make my final decisions about white balance during post-production. As spring and summer progress, that time will get earlier and earlier. Most avid night sky photographers will wait for the days just before, during, and after a new moon. How do you learn about sky conditions? Download one of many free or inexpensive apps. A popular app for the desktop is the free Stellarium app for Windows, Mac, and Linux.
I will say that shooting the sky without anything else in the frame tends to be boring, so try to include something in the foreground. Photographs with layers tend to be more interesting than an image without. If you live near a major city L. These settings are designed to flood the camera sensor with as much light as possible — from the sky itself. Any ambient light from the ground will throw way too much light onto the sensor, thus washing out your attempts. I teach night-sky workshops in Moab, Utah, because the sky there is so incredibly dark that you can see the Milky Way with just your eyes after they adjust.

Just drive 60—90 minutes away from the brightest, largest towns in your area. In the Boston area, for example, this means driving west towards the Berkshires, northwest towards Groton, Mass. In Salt Lake City you could drive up into the mountains near Solitude, Alta, or Snowbird, which puts you above much of the light pollution from the city. You can also drive south to places around Spanish Fork or further south to the national parks. Here are some settings that will get you started. If it shows a number i. This is basically a countdown timer that takes a photo each time the counter reaches 0: It then starts again, and will take pictures indefinitely until you stop it.
This 5-second delay should be enough time for your camera to write the captured image to the memory card and get ready to capture the next photo. If you find that your camera needs a second or two more, then change the interval setting to 32 or 33 seconds. This noise-reduction mode will take a black image equal in length to your set shutter speed and compare it to the snapped image in order to reduce noise.
The photo above is one frame from a sequence. However if you capture enough images, you can create a short time-lapse segment. In the final video see below I captured photographs over a period of 2. Capturing night sky time-lapses is equivalent to watching paint dry. The reason is twofold: You need to capture quite a few frames to make even a short video, and each frame can take 20, 30, or 40 seconds to capture. At the theater most films are played back at a frame rate of 24 frames per second, while the TV standard is 30fps.
Instead, capture enough for 6—8 seconds of video, then change the composition and shoot a second time-lapse if time allows.

Now the question is how long will this take? The answer is known once we take into account the interval between pictures. Since a new photo is being taken every 30 seconds I know that my camera will be taking 2 pictures every minute. I now have 90 minutes where I have nothing to do except gaze and marvel at the night sky.
Adobe Lightroom is a photo editing software package for PCs and Macs that allows you to import, catalog, and enhance photographs without actually making any changes to the original file. Anytime you want to re-edit a photograph, Lightroom looks for this sidecar file and loads in the series of changes you previously made.
Processing the Photo
This might have been the perfect setting for the beginning of the time-lapse, but as the sun set the color of the ambient light changed, yet the camera was still fixed on Tungsten. LRTimelapse allows you to set key frames stars on your images and then make adjustments to just those key frames inside Adobe Lightroom.
So now, instead of making incremental changes to every image, you just have to worry about two of them — the start and end key frames. You then make the adjustments needed in Lightroom and save the metadata changes to those two files. Reload the folder in LRTimelapse and it will ramp the changes you made in as many steps as there are photos. If you have a frame time-lapse, LRTimelapse will change the color temperature over the frames, making the change gradual and smooth.
LRTimelapse can ramp virtually any setting in Lightroom, making it a powerful tool for time-lapse photographers. This section is not really designed to teach you how to use Lightroom or LRTimelapse, but instead will take you through the basics that are needed to enhance your captured photos and turn them into a rendered time-lapse video sequence. Capturing and creating time-lapse videos require a great deal of patience, but the steps do become secondary once you have done them a couple of times.
There are other workflows that might make more sense when rendering multiple time-lapses sequentially, but for rendering one sequence at a time this is a popular workflow. I encourage you to make the time to shoot the night sky.
