The Night Sky In Landscape Photography - Digital Photography School

The Night Sky In Landscape Photography

This shot was taken with an EOS 5D Mark II and EF 24mm f/1.4L II lens. Exposure was 15 seconds, ISO 800, at f/1.4. The exposure for star fields should not be much longer than 15 seconds. Beyond 15 seconds, movement begins to creep in and slight star trails get recorded. In order to get the star fields to be as prominent as they are, I had to wait until the moon set behind me. Light pollution of any kind, be it the moon, street lights, or buildings, will diminish the intensity of the light of the stars. Moonless nights are best for photographing the night sky.

As a landscape photographer, I typically liked to work at sunrise and sunset.  But the night sky holds its own magic, with countless stars, the moon, and the Milky Way all out there waiting to be photographed.

Obviously, all night landscape photography happens on a tripod.  What type of shots you go for will depend greatly on your patience.  Night sky exposures can range from 15 seconds to several hours, depending on your goals.  Star fields can be captured with exposures of about 15 seconds, with aperture and ISO varying depending on the lens in use.

One important thing to be aware of is the available light around you. Any ambient light will diminish the intensity of the stars.  This includes the moon, streetlights, a town or city with buildings that have outside lights on, or even just car lights.  All of these will have negative effects on the exposure of the night sky.  The best thing to do is to find a rural area where there aren’t any street lights, traffic, buildings etc.  The stars will be most intense and easily photographed.

Because the night sky is best photographed, well, at night, it will be important to have a flashlight or other illumination to light the way while you hike to your location or assemble your gear.  Headlamps work exceptionally well for this.  These lights also come in handy for “painting” the foreground with light, to add some extra depth to your images.

In addition to the camera and lens, a remote release, or even better, a time controller is a necessity.  The remote release will allow you to trigger your camera without touching it. A timer remote control (such as the Canon TC-80N3) does that and more.  When shooting star trails, the timer can be programmed to take as long an exposure as needed. It can also be programmed to take several exposures in sequence if needed. This is helpful for stacking images, a common technique when shooting star trails.

I previously mentioned having a flashlight handy for painting the foreground.  Depending on the type of flashlight used, color correction gels can be useful as well.  Newer, LED flashlights have a much cooler light source than traditional flashlights, so a warming gel will help make it more natural looking. For lights using traditional bulbs, a cooling gel may be desired. Experimentation is essential here.  Too much light will ruin the exposure, too little won’t help the foreground the way that was intended. Generally, a quick kiss of light is all that may be needed.  A neutral density gel over the flashlight will help regulate it so just the right amount of light is applied.

For this image at Valley of Fire in Nevada, the arch made for the perfect foreground. But it was silhouetted against the night sky. Using an LED headlamp and a warming filter, I was able to illuminate the red rocks and balance that illumination with the ambient exposure for the night sky. This image was taken with the EOS 5D Mark III with EF 8-15mm Fisheye Zoom. Exposure was 15 seconds, ISO 6400 at f/4.

One problem with night time photography is the long exposures.  Digital imaging sensors generate heat when they capture an image, and that heat manifests itself as noise in a long exposure.   Today’s digital SLRs all have settings for long exposure noise reduction.  This is generally done through a method known as “Dark Frame Subtraction”.  First, the camera takes the image at the intended exposure.  For this case, let’s say it’s a 30 second exposure.  When long exposure noise reduction is enabled, the camera then takes a second exposure, this one with the shutter closed. The imaging sensor is charged, for the same amount of time as the original exposure. This second, dark frame, is then compared to the first frame taken.  Since both frames were “exposed” for the same length of time, the heat generated on the sensor should be the same, and thus the noise generated should be the same. The camera then compares the two frames, and removes the noise that is consistent in both frames. While the camera does this, it is not possible to take another exposure, so this can become a very long process for star trail images that could be as long as an hour or more. Batteries are of paramount importance for this procedure, as the image won’t be recorded if the battery dies before long exposure noise reduction is complete.  If your camera has an AC adapter, and a generator or other power source is available, it will make the stress of wondering if the camera has enough battery power go away.  If you plan on stacking multiple images for star trails, this feature should be turned off, since continuous images are needed to keep the star trails continuous.

Every year in the spring, during the full moon, a moonbow is created by the mist at Yosemite Falls. Taken with an EOS 5D Mark III, EF24mm f/1.4L II lens. Exposure was 10 seconds, ISO 1250, at f/4. It is readily apparent that the presence of the moon in the sky reduces the intensity of the stars, as compared to the shot of Half Dome above.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This image of the skies over upstate New York was made with the EOS-1D X with EF 8-15mm f/4L Fisheye Zoom. Exposure was 15 minutes, ISO 400 at f/4. One 15 minute exposure took 30 minutes due to the long exposure noise reduction setting. If longer star trails are desired, you can use a longer exposure and keep the long exposure noise reduction on, or you can take shorter exposures of about 5 minutes, in succession. Turn off long exposure noise reduction, and combine the images later on in Photoshop or other image editing software.

    Nice article! However, one can usually go with longer exposures without getting star-trails if a lens wide enough is used. The general rule is 600/x where x is the focal length of the lens. Thus if a 20mm lens is used, you could shoot at 30 seconds without getting star trails, if a 14mm lens is used, then 43 seconds will be okay and so on.

    @mei teng:
    Yes, that was around 9:30pm, I believe. Maybe a little later. Moonlight is simply reflected sunlight, so if you can get the exposure correct, a landscape lit by the full moon will often appear as if shot during the day.

  • shawmutt

    Or for those of us who can’t afford full frame cameras, it’s 600 x the effective focal length ;-).

  • http://www.rickberk.com Rick Berk

    I have found there to be a discrepancy between the “rule” and real world experience. With a 24mm lens, I was noticing the beginnings of star trails at 20 seconds. The “rule” says 25. I’d rather not push it if I am looking for pinpoint stars in the sky.

    Hi guys my camera is only an entry level (EOS 550D) & it doesn’t have the “noise reduction” option built in… is it possible to do this in post processing using CS6 if I just put the lens cap on for the second exposure????

    @ Daniel,
    The 550D (Rebel T2i in the US) DOES have Long Exposure Noise Reduction. You find it in the Custom Functions menu to enable it.

    Hi there, To prevent star trails for star shots use the 500 factor. This means that you divide the focal length of your lens into 500.There is a difference for full frame or other size sensors. Look up Dave Morrow Photography.com for a complete guide. Another useful free download is the Photographers Empherus which gives you sun and moor risings and settings plus their light path at any given spot on earth. There are guides on how to use this on You Tube. Hope you find this helpful
