Five Questions

Five Questions: Pixelstick Portraits, Motorized Mounts, Devils Tower and More

Welcome again to an NPAN Q&A, where we share some of the great questions weโ€™ve received via email. This time around we're featuring Qโ€™s and Aโ€™s about using a popular light writing tool with night portraits, motorized mounts in astro-landscape photography, the orientation of the Milky Way, loupes for Live View, and tips about shooting Devils Tower.

If you have any questions you would would like to throw our way, contact us anytime!

1. Pixelsticks and Portraits

Q. Can you tell me how you used the Pixelstick with speedlights [in the recent blog post โ€œTools for Illuminating the Nightโ€]? When do the lights fire, before or after you draw with the Pixelstick? โ€” Alison Carlino

A: The technique youโ€™re asking about is a long exposure where I use the flash first, ask the model to stand still, and then run behind with the Pixelstick while the shutter is open. You can do it in either order, but I prefer the order I use.

First, I meter the ambient exposure, and then drop it by a stop. Second, I set up each flash to expose as I prefer. Third, I test for the Pixelstick exposure. Finally, I work all those elements into a composition I like. Itโ€™s like spinning plates. Exciting!

Iโ€™m planning on holding a couple of night portrait workshops to teach this technique. Stay subscribed for early announcements. ;-) โ€” Matt

2. Motorized Mounts for Astro-landscape?

Q. I was curious about a motorized mount for night photography, such as the Sky-Watcher Star Adventurer. In the context of what we shoot with you guys (astro-landscape), that would not really ever be needed, right? In trying to figure out what that is used for, it seemed to be more for longer exposures of the sky alone, to get star points versus trails. It appears that if you include any foreground, the movement of the camera would blur it. โ€” Martha Hale

A: You are absolutely correct! Motorized mounts are excellent for astrophotography, such as for shooting planets, deep-space objects or even ultrahigh-detail shots of the moon. But if you were to try to include any Earth-based foreground element, that would blur. You could, however, use the mount to create great star points with a long exposure at a low ISO, and then in post-production layer that with a separate, sharp exposure of the foreground. โ€” Chris

3. Milky Way Orientation

Q. How do I know if the Milky Way will be an arch or in a vertical position? Is it in both positions at different times throughout the night? โ€” Susan Manley

A. The Milky Way is an amazing thing to witness and capture, and it inspires creativity!

In the Northern Hemisphere the Milky Way season officially begins in April and goes until September. We can see the Milky Way all year, but the galactic core, or brightest part of the Milky Way, breaches the horizon at night during those months. It rises at about 2 to 4 a.m. in March, midnight to 2 a.m. in April, 10 p.m. to midnight in May, 8 to 10 p.m. in June, and earlier and earlier in the night through the summer. By August, it is high overhead by the time the sky gets dark.

The best time to see and photograph the long arc of the Milky Way is from late April to July, on nights with little to no moon.

Which orientation is preferred for photography? Totally your choice. The Milky Way arc is really a camera effect caused by including this massive astronomical structure arching across the sky in one photograph. It is best achieved by creating a panorama of four to eight stitched images. That way you can encompass the whole arc with minimal distortion. (You can learn more about that technique in our CreativeLive course.) On the other hand, when the Milky Way core shoots straight into the air from the horizon, you can capture the core with one exposure and be creative with where it intersects with the foreground.

By the way โ€ฆ itโ€™s Milky Way season right now. Carpe noctem! โ€” Gabe and Lance

4. Loupe for Live View

Q: Iโ€™m thinking of buying a loupe to use with Live View focusing on my Nikon D750. Trying to decide which model to buy. โ€” S.G.

A: A loupe can be an excellent accessory for helping to focus at night. Iโ€™ve been using since last year not only because it can help to ease the focusing process in general, but also because my 45-year-old eyes appreciate the assist in focusing on the cameraโ€™s LCD! A focusable loupe does just that.

For the Nikon D750 (awesome night camera, BTW!), the HoodMan Compact Hoodloupe is an excellent choice, in terms of both quality and being the right size for the D750, or any of the very many other cameras with similar-size LCDs (i.e., 3.2 inches). โ€” Chris

5. Devils Tower Tips

Q: I will be traveling to Devils Tower National Monument in Wyoming. Per TPE, the moonrise time will provide a window of dark sky. Any suggestions for where to shoot? Iโ€™m looking at using my Genie Mini, doing time-lapse, panos or some star trails (with as little light pollution as possible) โ€ฆ Iโ€™m not picky, and will see what the moment dictates. โ€” Megan

A: Devils Tower is actually really easy to shoot. Itโ€™s a rather small property that is circular. Some of my favorite locations are:

  1. From just outside the park, before the hotel/trading postโ€”that curve in the road gives you a nice, long shot at the open sky with the tower in the middle. Ripe for a 70-200mm lens for details and long star trails.
  2. As you come in, there will be a parking lot to the left. Shooting from there gives you an awesome view of the North Star over the tower.
  3. As you drive to the base of the tower, there is one road to the left. Take that left, park in the little lot, and shoot from that meadow for a cool view. Last time I was there, we had stars and a thunderstorm at the same time. Amazing.
  4. Right up at the base of the tower is another great location, with a classic view as you come off the trail. And you can walk around the whole thing, which gives you a ton of photo options.

When shooting at Devils Tower, use the buddy system, and watch for sleeping snakes. I startled one onceโ€”Iโ€™m not sure who was more scared, the snake or me! Stay on the path for greatest safety. Scout during the daytime and youโ€™ll find all these spots. There isnโ€™t much light pollution out there, so enjoy the darkness! โ€” Matt

UPCOMING WORKSHOPS FROM NATIONAL PARKS AT NIGHT

Five Questions: Offering Answers on Gear, Techniques and Etiquette

As you might imagine, we get emails from time to time asking us questions about night photography. Weโ€™re always happy to respond personally to those questions. However, thereโ€™s also the (largely correct) theory that for every person who asks a question, there are a hundred others who want to know the same thing but didnโ€™t ask.

Therefore, we have decided that from time to time we will collect five of the questions that have recently been asked of us, and share them, along with our answers, with all of our blog readers. We hereby commence this โ€œFive Questionsโ€ series today.

Our first foray into shedding some light on night photography conundrums includes some excellent questions on gear, techniques and etiquette.

1. SharpStar2 and the Nikon 14-24mm

Q: I have the Nikon 14-24mm f/2.8 lens. I have just finished reading about the SharpStar2. In my very limited experience with photographing stars, I have yet to obtain anything close to a sharp focus on them. Thus Iโ€™m intrigued by the SharpStar2. Can this be used with the lens Iโ€™ve mentioned? Iโ€™m assuming I would have to purchase the appropriate square filter holder and the appropriate size SharpStar 2 filter. Could you tell me what size to order, and which filter holder youโ€™d recommend? โ€” Liela N.

A: Although the Nikon 14-24mm is one of the best lenses for night photography, itโ€™s actually not one I can recommend for combining with the SharpStar2. In fact, Iโ€™m not sure thereโ€™s a way to get it to work at all. The issue is that lens has the bulbous front element, which means a flat filter canโ€™t be used without retrofitting a holder. Thereโ€™s a great article on Naturescapes titled โ€œAdapting Filters to Fit the Nikon 14-24mm Lensโ€ that explains why and offers a DIY solution, but it requires a 150mm filter, and the largest that SharpStar2 comes in is 100mm.

But I would definitely hold on to that lens for night photography! If youโ€™d like to work on other techniques for focusing in darkness, Iโ€™ll offer three suggestions:

  1. Use Live View. Itโ€™s infinitely easier than trying to focus through your viewfinder.
  2. Try presetting your lens to infinity during daylight, then turn off autofocus and tape down the focus ring.
  3. Use hyperfocal distance.

Incidentally, if youโ€™re interested in purchasing the SharpStar2 for other lenses, we have a discount code we can share with you. Use โ€œNPAN10โ€ to receive 10 percent off the SharpStar2 on LonelySpeck.com. โ€” Chris

2. Stack-a-Matic

Q: I use Photoshop/Lightroom CS6. I am a new user to Photoshop so obviously still learning. I tried to download your recommended Stack-A-Matic but I get an error that says I need Photoshop 12 or higher. What is a good stacking program that goes with CS6? โ€” Sue W.

A: Stack-a-Matic works with CS5 thru CC (latest). Did you download it from my website, and use the manual installation instructions? Sometimes itโ€™s a little bit finicky, but it does work. You might have to do a restart, or possibly walk through the installation twice, but itโ€™s worth it.

Iโ€™m sorry that I canโ€™t offer more tech support than this for Stack-a-Matic; Iโ€™m just hosting it for Russell Brown. Alternatively, you can try StarStax for Mac, and Startrails.exe for PC. โ€” Lance

3. Light painting in Arches National Park

Q: I heard/read that Arches National Park has closed the permits for night photography. Does this mean for workshops or personal? โ€” Juan Aguilera

A: Yes, Arches (and Canyonlands National Park) did institute a rule change this year, but it applies only to instructor-led groups using an official CUA (Commercial Use Authorization) permit, and for the moment it applies only to light painting.

If you go on your own as a photographer, there are no restrictionsโ€”for now. But if photographers donโ€™t collectively respect that environment (i.e., behave ourselves), who knows what might change? While we donโ€™t agree with a blanket rule change in Arches, we do understand why it was implemented. We always talk about the etiquette of doing night photography in a way that doesnโ€™t negatively affect others who are enjoying the same dark skies that weโ€™re photographing. (See the early sections of the โ€œNight Photography in National Parksโ€ presentation Lance and Chris did at the B&H Event Space a few months ago.)

However, itโ€™s also good to note that if youโ€™re planning to shoot in Arches in 2017, the park will be closed at night every Sunday through Thursday due to road construction. So you can do night photography only on Fridays and Saturdays, until the expected November completion date. โ€” Matt

4. Aurora in New England?

Q: Is there any chance of seeing aurora in New England? And is there a good app that you use for potential activity? โ€” HersheyArtImages

A: The aurora can occasionally be seen in southern New England, but it is usually just a little bit of green near the horizon in the northern sky, when seen from a dark beach with a view to the north. In the northern parts of Vermont, New Hampshire and Maine, it is seen a little more frequently.

We use an app called Aurora Forecast, which is available for both iOS and Android. Once you download it, you can customize the settings to send you an alert for a kp (the unit of measurement of auroral activity) of 6 or higher in the middle latitudes. If the activity is much less than that, you are not likely to see anything.

You will never see aurora from a light-polluted area so far south. Really strong displays can sometimes be viewed right in the center of Reykjavik โ€“โ€“ but that is a much smaller city, with much smaller suburbs. โ€” Lance

5. Dealing with light pollution

Q: I am struggling with processing wide-field astrophotography images (starscapes, Milky Way, etc.). In particular, with how to remove light pollution, which is an unfortunate fact of life for those of us living in the eastern part of the country. For wide-field photographs, the light pollution is usually graduated over the image, being brightest at the horizon and diminishing at you go higher. I would very much appreciate any tips you might have in this area. โ€” David T.

A: Honestly, I generally donโ€™t do anything to try to rid light pollution from my night photos, but rather try to use that extraneous light creatively. Specifically, I use the distant light to create silhouettes of mountains, for example, or to light clouds in the sky. Both of those tactics can provide depth to otherwise pitch-dark scenes.

If you do want to negate the color effect of light pollution in the night sky, a tech option is to try one of the new filters for eliminating the color cast in the sky that can be caused by light pollution. Our friends at Lonely Speck recently released the PureNight filter, which is made from a special didymium glass that reduces the transmission of light from sodium vapor lamps. We have yet to try it, but they know their stuff, so itโ€™s likely an excellent solution. We also just heard about the NiSi Natural Night Filter from Ikan, but again, we havenโ€™t had the pleasure of trying it yet. โ€” Chris
