It was a magical night as the rising Moon lit the Badlands with a golden glow.
When doing nightscape photography it’s often best not to fight the Moon, but to embrace it and use it as your light source.
I did this on a fine night, Easter Sunday, at one of my favourite nightscape spots, Dinosaur Provincial Park.
I set up two cameras to frame different views of the hoodoos as they lit up with the light of the rising waning Moon.
The night started out as a dark moonless evening as twilight ended. Then about 90 minutes after the arrival of darkness, the sky began to brighten again as the Moon rose to illuminate the eroded formations of the Park.
This was a fine example of “bronze hour” illumination, as some have aptly called it.
Photographers know about the “golden hour,” the time just before sunset or just after sunrise when the low Sun lights the landscape with a golden glow.
The Moon does the same thing, with a similar tone, though greatly reduced in intensity.
The low Moon, especially just after Full, casts a yellow or golden tint over the scene. This is caused by our atmosphere absorbing the “cold” blue wavelengths of moonlight, and letting through the “warm” red and yellow tones.
Making use of the rising (or setting) Moon to light a scene is one way to capture a nightscape lit naturally, and not with artificial lights, which are increasingly being frowned upon, if not banned at popular nightscape destinations.
“Bronze hour” lighting is great in still-image nightscapes. But in time-lapses the effect is more striking — indeed, in time-lapse lingo it is called a “moonstrike” scene.
The dark landscape suddenly lights up as if it were dawn, yet stars remain in the sky.
The best nights for such a moonstrike are ones with a waning gibbous or last quarter Moon. At these phases the Moon rises after sunset, to re-light a scene after evening twilight has faded.
On April 21 I made use of such a circumstance to shoot moonstrike stills and movies, not only for their own sake, but for use as illustrations in the next edition of my Nightscapes and Time-lapse eBook (at top here).
One camera, the Nikon D750, I coupled with a device called a bramping intervalometer, in this case the TimeLapse+ View, shown above. It works great to automatically shift the shutter and ISO speeds as the sky darkens then brightens again.
Yes, in bright situations the camera’s own Auto Exposure and Auto ISO modes might accomplish this.
But … once the sky gets dark the Auto circuits fail and you’re left with hugely underexposed images.
The TimeLapse+ View, with its more sensitive built-in light meter, can track right through into full darkness, making it possible to shoot so-called “holy grail” time-lapses that go from daylight to darkness, from sunset to the Milky Way, all shot unattended.
For the other camera, the Sony a7III (with the Laowa 15mm lens I just reviewed) I set the camera manually, then shifted the ISO and shutter speed a couple of times to accommodate the darkening, then brightening of the scene.
Processing the resulting RAW files in the highly-recommended program LRTimelapse smoothed out all the jumps in brightness to make a seamless transition.
I also used the new intervalometer function that Sony has just added to the a7III with its latest firmware update. Hurray! I complained about the lack of an intervalometer in my original review of the Sony a7III. But that’s been fixed.
I shot 425 frames with the Sony, which I not only turned into a movie but, as one can with time-lapse frames, I also stacked into a star trail still image, in this case looking north to the circumpolar stars.
I prefer this action set over dedicated programs such as StarStaX, because it works directly with the developed Raw files. There’s no need to create a set of JPGs to stack, compromising image quality, and departing from the non-destructive workflow I prefer to maintain.
While the still images are very nice, the intended final result was this movie above, a short time-lapse vignette using clips from both cameras. Do watch in HD.
I rendered out the frames from the Sony both as a “normal” time-lapse, and as one with accumulating star trails, again using the Advanced Stacker Plus actions to create the intermediate frames for assembling into the movie.
All these techniques, gear, and apps are explained in tutorials in my eBook, above. However, it’s always great to get a night perfect for putting the methods to work on a real scene.
In a “10 Steps” tutorial I review my tips for going from “raw to rave” in processing a nightscape or time-lapse sequence.
NOTE: Click on any of the screen shots below for a full-res version that will be easier to see.
In my preferred “workflow,” Steps 1 through 6 can be performed in either Photoshop (using its ancillary programs Bridge and Adobe Camera Raw) or in Adobe Lightroom. The Develop module of Lightroom is identical to Adobe Camera Raw (ACR for short).
However, my illustrations show Adobe Bridge, Camera Raw and Photoshop CC 2014. Turn to Photoshop to perform advanced filtering, masking and stacking (Steps 7 to 10).
To use Lightroom to assemble a time-lapse movie from processed Raw frames you need the third-party program LRTimelapse, described below. Otherwise, you need to export frames from Lightroom – or from Photoshop – as “intermediate” JPGs (see Step 6), then use other third party programs to assemble them into movies (Step 10B).
Step 1 – Bridge or Lightroom – Import & Select
Use Adobe Bridge (shown above) or Lightroom to import the images from your camera’s card.
As you do so you can add “metadata” to each image – your personal information, copyright, keywords, etc. As you import, you can also choose to convert and save images into the open and more universal Adobe DNG format, rather than keep them in the camera’s proprietary Raw format.
Once imported, you can review images, keeping the best and tossing the rest. Mark images with star ratings or colour labels, and group images together (called “stacking” in Bridge), such as frames for a panorama or “high dynamic range” set.
Always save images to both your working drive and to an external drive (which itself should automatically back up to yet another external drive). Never, ever save images to only one location.
Step 2 – Adobe Camera Raw or Lightroom – Basics
Open the Raw files you want to process. From Bridge, double click on raw images and they will open in ACR. In Lightroom select the images and switch to its Develop module.
In Adobe Camera Raw be sure to first set the Workflow Preset (the blue link at the bottom of the screen) to 16 bits/channel and ProPhoto RGB colour space, for maximum tonal range. This is a one-time setting. Lightroom defaults to 16-bit and the AdobeRGB colour space.
The Basics panel (the first tab) allows you to fix Exposure and White Balance. For the latter, use the White Balance Tool (the eyedropper, keyboard shortcut I) to click on an area that should be neutral in colour.
You can adjust Contrast, and recover details in the Highlights and Shadows (turn the latter up to show details in starlit landscapes). Clarity and Vibrance improves midrange contrast and colour intensity.
Use Command/Control Z to Undo, or double click on a slider to snap it back to zero. Or under the pull-down menu in the Presets tab go to Camera Raw Defaults to set all back to zero.
Step 3 – Adobe Camera Raw or Lightroom – Detail
The Detail panel allows you to set the noise reduction and sharpness as you like it, one of the benefits of shooting Raw.
Generally, settings of Sharpness: Amount 25, Radius 1 work well. Turn up Masking while holding the Option/Alt key to see what areas will be sharpened (they appear in white). There’s no need to sharpen blank, noisy sky, just the edge detail.
Setting Noise Reduction: Luminance to 30 to 50 and Color to 25, with others sliders left to their defaults works well for all but the noisiest of images. Luminance affects the overall graininess of the image. Color, also called chrominance, affects the coloured speckling. Turning the latter up too high wipes out star colours.
Turn up Color Smoothness, however, if the image has lots of large scale colour blotchiness.
Zoom in to at least 100% to see the effect of all noise reduction settings. Adobe Camera Raw and Lightroom have the best noise reduction in the business. Without it your images will be far noisier than they need to be.
Step 4 – Adobe Camera Raw or Lightroom – Lens Correction
Wide angle lenses, especially when used at fast apertures, suffer a lot from light falloff at the corners (called vignetting). There’s no need to have photos looking as if they were taken through a dark tunnel.
ACR or Lightroom can automatically detect what lens you used and apply a lens correction to brighten the corners, plus correct for other flaws such as chromatic aberration and lens distortion.
Use the Color tab to “Remove Chromatic Aberration” and dial up the Defringe sliders.
For lenses not in the database (manual lenses like the Rokinons and Samyangs will not be included, nor will any telescopes) use the Manual tab to dial in your own vignetting correction. This can take some trial-and-error to get right, but once you have it, save it as a Preset to apply in future to all photos from that lens or telescope.
I usually apply Lens Corrections as a first step, but sometimes find I have to back it off it as I boost the contrast under Basics.
Step 5 – Bridge or Lightroom – Copy & Paste
For a small number of images you could open them all, then Select All in ACR to apply the same settings to all images at the same time.
Or you can adjust one, then Select All and hit Synchronize.
Another method useful for processing dozens or hundreds of frames from a star trail or time-lapse set is to choose one representative image and process it. Then in Bridge choose Edit>Develop Settings>Copy Camera Raw Settings. If you are in Lightroom’s Library module, choose Photo>Develop Settings>Copy Settings.
With either program you can also right-click on an image to get to the same choices. Then select all the other images in the set (Command/Control A) and use the same menus to Paste Settings.
A dialog box comes up for choosing what settings you wish to transfer.
If you cropped the image (a good idea for images destined for an HD movie with a 16:9 aspect ratio), pick that option as well. In moments all your images get processed with identical settings. Nice!
Step 6 – Lightroom or Photoshop – Export
You now have a set of developed Raw images. However, the actual Raw files are never altered. They remain raw!
Instead, with Adobe Camera Raw the information on how you processed the images is stored in the “sidecar” XMP text files that live in the same folder as the Raw files.
In Lightroom’s case your settings are stored in its own database, unless you choose Metadata>Save Metadata to File (Command/Control S). In that case, Lightroom also writes the changes to the same XMP sidecar files.
To convert the images into final Photoshop PSDs, TIFFs or JPGs you have a couple of choices. In Lightroom go to the Library module and choose Export. It’s an easy way to export and convert hundreds of images, perhaps into a folder of smaller JPGs needed for assembling a time-lapse movie.
To do that from within Adobe Bridge, select the images, then go to Tools>Photoshop>Image Processor. The dialogue box allows you to choose how and where to export the images. Photoshop then opens, processes, and exports each image.
Step 7 – Photoshop – Smart Filters
For a folder of images intended to be stacked into star trails (Step 10A) or time-lapse movies (Step 10B), you’re done processing.
But individual nightscape images can often benefit from more advanced work in Photoshop. The next steps make use of a non-destructive workflow, allowing you to alter settings at any time after the fact. At no time do we actually change pixels.
One secret to doing that is to open an image in Photoshop and then select Layer>Smart Objects>Convert to Smart Object. Or go to Filter>Convert for Smart Filters.
OR … better yet, back in Adobe Camera Raw hold down the Shift key while clicking the Open Image button, so it becomes Open Object. That image will then open in Photoshop already as a Smart Object, which you can re-open and re-edit in ACR at any time later should you wish.
Either way, with the image as a Smart Object, you can now apply useful filters such as Reduce Noise, Smart Sharpen, and Dust & Scratches, plus third-party filters such as Nik Software’s Dfine 2 Noise Reduction, all non-destructively as “smart filters.” They can be re-adjusted or turned off at any time.
Step 8 – Photoshop – Adjustment Layers
The other secret to non-destructive processing is to apply adjustment layers.
Go to Layer>New Adjustment Layer, or click on any of the icons in the Adjustments panel. If that panel is not visible at right, then under the Window menu check “Adjustments.”
This panel is where you can alter the colour balance, the brightness and contrast, the vibrancy, and many other choices. I find Selective Color most useful for tweaking colour.
Curves allows you to bring up detail in dark areas. Levels allows setting the black and white points, and overall contrast.
The beauty of adjustment layers is that you can click on the layer’s little icon and bring up the dialog box for changing the setting at any time. You never permanently alter pixels.
The image adjustment “Shadows & Highlights” is also immensely useful, but appears as a smart filter, not as an adjustment layer. It’s one of the prime tools for creating images with great detail in scenes lit only by starlight.
Step 9 – Photoshop – Masks
The power of adjustment layers is that you can apply them to just portions of an image. This is useful in nightscapes where the sky and ground often need different processing.
To create a mask first select the region you want to work on. Try the Quick Selection Tool (found near the top of the Tool palette at left). Use it to brush across the sky, or the ground, so that the entire area is outlined by “marching ants.”
Use the Refine Edge option to tweak the selection by brushing across intricate areas such as tree branches.
Once you have an area selected, hit one of the Adjustments to add an adjustment layer with the mask automatically applied. Double click on the mask to tweak it: hit Mask Edge to clean up the edge, or turn up the Feather to blur the edge.
To apply the same mask to another adjustment layer, drag the mask from one layer to another while holding down the Option/Alt key.
Invert the mask (or select it and hit Command/Control I) to apply it to the other half of the image. Paint the mask with black or white brushes if you need manually alter it. Remember – black “conceals,” while white “reveals.”
When done, be sure to always save the image as a layered “master” .PSD file.
Never, ever flatten and save – that will wipe out all your non-destructive filters and adjustment layers.
If you need to save the image as a JPG for social mediia or emailing, then Flatten and Save As … Or use Photoshop’s File>Export>Export As .. function.
Step 10A – Photoshop or 3rd Party Programs – Stack for Star Trails
One popular way to shoot images of stars trailing in arcs across the sky is to shoot dozens or hundreds of well-exposed frames at a fairly high ISO and wide aperture, and at a shutter speed no longer than 30 to 60 seconds. You then “stack” the images to create the equivalent of one frame shot for many minutes, if not an hour or more. The image above is an example.
There are several ways to stack.
From within Photoshop CC (or using an Extended version of the older CS5 or CS6) one method is to go to File>Scripts>Statistics. In the dialog box, drill down to the images you wish to stack (put them all in one folder) and choose Stack Mode: Maximum, and uncheck “Attempt to Automatically Align.” The result is a huge (!) smart object. This method works best on just a few dozen images. In this case, you’ll need to use Layers>Flatten to reduce its size.
Other options for stacking hundreds of images include the free program StarStax (Windows and Mac), which requires a folder of “intermediate” TIFFs or JPGs. See Step 6 above.
Step 10B – Photoshop or 3rd Party Programs – Assemble for Movies
The same folder of images taken for star trail stacking can also be turned into a time-lapse movie. Instead of stacking the images on top of one another in space, you string them together one after the other in time.
There are many methods for assembling movies. Free or low cost programs such as Quicktime 7 Pro, Time-Lapse Assembler, Sequence (a Mac program shown above), VirtualDub, or Time-Lapse Tool can do the job, all offering options for the final movie’s format.
Generally, an HD video of 1920×1080 pixels in the H264 format, or “codec,” is best, rendered at 15 to 30 frames per second.
Most movie assembly programs will need to work from a folder of JPGs of the right size, produced using one of the choices listed under Step 6: Export.
But … you can also use Photoshop to assemble a movie.
Choose the Window>Workspace>Motion to bring up a video timeline. Then File>Open to drill to your folder of processed and down-sized JPG files. Select one image, then check “Image Sequence.” Choose the frame rate (15 to 30 fps is best). Then go to File>Export>Render Video to turn the resulting file into a final H264 or Quicktime movie suitable for use in other movie editing programs.
Advanced Techniques: Using LRTimelapse
The workflow I’ve outlined works great when you can apply the same development settings to all the images in a folder. For star trail and time-lapse sequences shot once it gets dark and under similar lighting conditions that will be the case.
But if the Moon rises or sets during the shoot, or if you are taking a much more demanding sequence that runs from sunset to night, the same settings won’t work for all frames.
The answer is to turn to the program LRTimelapse (100 Euros for the standard version, and available in a free but limited trial copy). LRTimelapse works with either Lightroom or Bridge/Adobe Camera Raw.
To use it you process just a few selected “keyframes” – at least two, at the start and end of the sequence, and perhaps other frames throughout the sequence, processing them so each frame looks great. You read that processing data into LRTimelapse and, like magic, it interpolates your settings, creating a folder of images with every setting changing incrementally from frame to frame, something you could never do by hand.
It can then work with Lightroom to export the frames out to a video in formats from HD up to 4K in size. For serious time-lapse work, LRTimelapse is an essential tool.

I present a short time-lapse vignette of scenes shot under moonlight on the Alberta prairie.
The movie linked below features sequences shot July 29 and 30, 2015 on beautifully clear moonlit nights at locations south of Bow Island, Alberta, on the wide open prairie. The three-minute video features two photogenic pioneer sites.
The church is the now derelict St. Anthony’s Church, a former Roman Catholic church built in 1911 by English and Russian-German immigrants. It served a dwindling congregation until as late as 1991 when it closed. At that time workers found a time capsule from 1915 with names of the priest and parisioners of the day.
The wood church seems to have been largely neglected since.
In the summer of 2014 the Church suffered its latest indignity when the iron cross on its steeple tower was stolen. I also shot in the pioneer cemetery of the Church.
The other site is a nearby farmhouse with photogenic textures and accompanied by rustic out buildings that are barely managing to stand.
Illumination was from a waxing gibbous Moon, just 1 to 2 days before the infamous “Blue Moon” of July 31. Its bright light turned the sky blue, and lit the landscape with the same quality as sunlight, because it is sunlight!
Enlarge the video to full screen for the full HD version.
For the technically inclined:
I shot the scenes with three cameras – a Canon 60Da, Canon 6D, and Nikon D750.
The Nikon, with a 24mm lens, was on the Dynamic Perception Stage Zero Dolly and Stage R panning unit, while the 60Da, with a 14mm lens, was on the compact Radian panning unit. The third camera, the 6D, with a 16-35mm lens, was on a fixed tripod for the star trail sequences and stills.
The music is by Adi Goldstein (AGSoundtrax.com), whose music I often use in my sequences. It just seems to work so well, and is wonderfully melodic and powerful. Thank you, Adi!
To process the several thousand frames that went into the final movie, I used Adobe Bridge and Adobe Camera Raw, supplemented by the latest Version 4.2 of LRTimelapse (lrtimelapse.com). Its new “Visual Deflicker” workflow does a beautiful job smoothing out frame-to-frame flickering in sequences shot in twilight under darkening lighting conditions. Thank you Gunther!
For the star trail sequences and the still images above I used the Advanced Stacker Actions from StarCircleAcademy.com. Unlike most other stacking programs, the Stacker Actions work from within Adobe Bridge and Photoshop directly, using the processed Raw images, with no need to create intermediate sets of JPGs. Thank you Steven!
The much-publicized “Blue Moon” of July rises over the skyline of Calgary.
Last night, July 31, many people looked east to see a wonderful moonrise. Did it look different than any other moonrise? No. But did it look great? You bet.
I set up my cameras at a site in northwest Calgary, picked for its sightline looking east-southeast over the downtown core of Calgary and directly toward the moonrise point.
I used the software The Photographer’s Ephemeris to plan the location and angles. It is wonderful for making sure you are in the right place at the right time for catching a photogenic moonset or moonset.
Here’s the screen shot from TPE that showed me where to be Friday evening. The blue line aims to the moonrise point.
Of course, despite the planning the Moon did not look blue! Blue Moons, as they have come to be defined, never do. The term now means the second Full Moon in a calendar month. We had a Full Moon on Canada Day, July 1, and then enjoyed a second July Full Moon one lunar cycle later on July 31.
I shot the scene with two cameras, each shooting hundreds of frames for time-lapses, from which I extracted still images.
A short 1-minute music video of the result is here at Vimeo. Enlarge the screen and be sure HD is selected.
As a technical note, for the processing I used the latest version 4.2 ofLRTimelapse and its new “Visual Deflicker” workflow which very nicely smooths out all the frame-to-frame flickering that can plague daytime and twilight shots taken under Auto Exposure.
While the shutter speed does constantly decrease, it does so in 1/3rd-f/stop steps, yielding stair-step jumps in brightness. LRT smooths all that out, with v4.2 doing a much better job than earlier versions.
My new 3-minute music video compiles still and time-lapse imagery of the aurora I shot in February 2015 from Churchill, Manitoba.
Churchill’s location at 58° North on the shore of Hudson Bay puts it directly under the main auroral oval, the zone of greatest auroral activity. Over the 9 nights, 2 were cloudy, with a roaring blizzard.
But on the 8 clear nights we saw aurora every night. I shot time-lapses on 6 of those nights, shooting about 3,500 frames, most of which appear in the final cut of this movie.
Despite the amazing displays we saw, on no night was the auroral activity index (on a scale of 0 to 9) higher than 2 or 3. These were all “normal” quiet nights for auroras in Churchill. Anyone farther south would have seen little in their sky on most of these nights.
I shot many of the time-lapses with an 8mm spherical fish-eye lens, to create sequences suitable for projection in digital planetarium domes. One other time-lapse sequence (the last in this movie) I shot with a 15mm full-frame fish-eye. Even it is not wide enough to take in the entire display when the Lights fill the sky.
Exposures were typically 10 to 15 seconds at f/3.5 and ISO 1600 to 4000, all with the Canon 6D. I powered it from its lone internal battery. Amazingly, despite temperatures that were considered extreme even for Churchill (often -32° C at night) the batteries lasted 90 to 150 minutes allowing me to take lots of frames with no battery change or perhaps just one battery change. Churchill is very dry and only on one night did I have an issue with the lens frosting up.
Music is by Dan Phillipson, his composition “Into the Unknown,” purchased for royalty-free use through Triple Scoop Music. I edited the movie in Apple Aperture, with a title sequence created in Photoshop. Processing of the original images was with Adobe Camera Raw, Photoshop, and LRTimelapse, with assembly of movie frames done with Sequence for MacOS.
I hope you enjoy it! Do click on the Enlarge button to watch it full screen. It may take a while to start playing.
It was a good year for time-lapse photography at home. Here’s my compilation of Alberta time-lapses in a 3-minute music video.
For a year-end look back at 2013 I assembled these highlights of my year of shooting time-lapse movies of the Alberta sky, by day and night.
I’ve included clips shot around home in rural southern Alberta, and further afield at popular photo spots around the province such as Waterton Lakes National Park, Banff, Writing-on-Stone Provincial Park, and Cypress Hills Provincial Park.
I hope you enjoy it! Be sure to maximize the video screen and select HD. Or for a better grade version check out my Vimeo channel.
Some technical background:
I shot all the frames for the movies (150 to 300 frames for each clip) with either a Canon 5D MkII or a Canon 60Da camera, equipped with various lenses from 8mm to 200mm. For many of the clips the cameras were on motion control devices: the Radian azimuth panning unit, an Orion TeleTrack mount, or aDynamic Perception Stage Zerodolly unit. You see the latter in action behind the credits.
