Questions and Answers

Processing Airglow

People have asked me a number of questions about equipment, issues, and technique in Nightscape or Landscape Astrophotography. Since many of these questions are recurring, I am going to post the questions and answers here. I’ll answer your questions to the best of my ability!

Q: Very nice panoramic in a wonderful place. One question Wayne, always in your picture I'm looking the airglow, Are you lucking or a special technique? ;-), thanks, Regards.

A: Thanks for looking Gabriel. The answer is both, sometimes lucky, and sometimes processing technique. There is frequently some degree of airglow present, but not always. If the airglow is present then the processing workflow I use does enhance it along with the light pollution. Lots of people try to get rid of the airglow and make the skies more uniform in color to meet their own and others expectations about the night sky. There are actions and workflows to get rid of these colors. Instead I go the opposite direction and enhance them to some degree if they are present. I start in Lightroom and then export to Photoshop. If you make the sky blue from the outset in Lightroom, it covers up most of the airglow and decreases light pollution to some degree. It can also make the airglow and light pollution a less pleasing color. If you initially make the darkest part of the sky a neutral "greyish" in Lightroom it will bring out more colors in the sky near the horizon later in processing. The subtle colors are less suppressed, and when you make the darkest sky more neutral it actually makes the colors of light pollution and airglow a more pleasing color and less of a "ugly" color. I export to photoshop and increase contrast in the sky in curves, and later make the sky bluer at the end. I describe the process here:

Questions and Answers

Rattlesnakes!

Q: Do you worry about rattlesnakes in the desert at night?

A: You can bet I do keep a lookout for rattlesnakes at night! I am very conscious of where I step, and wear really high boots. It's not what most people think of with night photography, but I try to make sure I come back alive! It's a different world out there with limited vision (darkness), but a really beautiful world. I love it! In a more general sense you have to pay attention to where you and walking and what you are doing, and generally move slowly and carefully. A bigger danger is climbing on large rocks and boulders at night. When you turn the lights off you really need to know where you can move your feet.

Utah’s Canyon Country by Wayne Pinkston Via Flickr: Website, Instagram, Facebook The Colorado River passes through the canyons of Utah. This is a breathtaking vista and one of my favorite spots to visit in central Utah. This is a panorama of multiple vertical images with the long exposure foreground images and separate images for the sky (from the same location consecutively), blended in PS. FG: 35 mm, 240 sec, f/1.8, ISO 2000. Sky: 24 mm, 15 sec, f/2.8, ISO 8000.

Canyonlands National Park by Wayne Pinkston Via Flickr: Website, Instagram, Facebook Panorama Foreground: 16 frames, 30 sec., f/2.5, ISO 2000 (twilight) Sky: 16 frames, 4 exposures each, stacked, f/1.8, 10 sec., ISO 500: All at 35 mm Canyonlands National Park. Panorama with the foreground and sky acquired separately as above. Thanks for looking! Wayne

Stranger in a Strange Land by Wayne Pinkston Via Flickr: This was the name of a book published in 1961 by Robert A. Heinlein (a very good early sci-fi book), and this is how I felt wandering around the Bisti Badlands of New Mexico at night. It is an extensive area with no marked trails, and a maze of washes, ravines, hills, ridges, etc. It is a broken landscape full of small to moderate sized hoodoos of every shape imaginable. There are also a number of petrified trees. It is incredibly easy to get lost at night because you cannot walk anywhere in a straight line. I used a GPS app and still had trouble getting back to the car because of deep ravines. Anyway it is an amazing place and well worth a trip. This is a single exposure. This photo was lit with reflected light from a hand held halogen spotlight/torch. I reflected the light off of a formation to my left, diffusing the light, and also illuminating the scene from the side. Hope you enjoy! Please join me at: Website Facebook Blog

Nankoweap Overlook, East Rim of the Grand Canyon by Wayne Pinkston Via Flickr: Website Instagram Faceb ook Nankoweap Overlook on the East Rim of the Grand Canyon. This is an remote undeveloped area along the western margin of the Navajo Nation and along the East Rim of the Grand Canyon. There are many miles/km of dirt roads and tracks to reach this site, but most of them are flat and in good condition. In 3 days of scouting and 3 nights of shooting I encountered 0 people. You do need a Navajo permit to travel in this area. This is a blend of 2 images taken back to back from the same spot, a 240 sec. image of the foreground at 14 mm, f 2.0, and ISO 2500 with long exposure noise reduction (LENR), and a sky image taken at 20 sec., 14mm, f 2.0, and ISO 12,800 and blended in PS. In my opinion the river views along this part of the canyon are much better than on the South or North Rims. The light pollution is from the South Rim and tourist area many miles away. One perplexing note - the area is on the edge of the Navajo Nation which uses Daylight Savings Time, and Arizona which does not use DST. If you are using your smartphone for planning Milky Way shots (example TPE, Photopillls, PlanIt) and you leave your phone on "Auto Time Zone", strange things will happen. You can walk 10 ft., 3 m, and your time zone will change, and sometimes the time and time zone will change back in forth standing in one place. You start wondering "what time is it really?", and "just what time zone did I plan for?". I marked times to be in certain spots and then had no idea what time it really was, lol. Advice: pick a time zone and take your phone off auto before you ever get there! Cheers, Wayne For more images like this please take a look at Wayne Pinkston Photography . Thanks for all the kind support! Hope you enjoy! A big thank you to the wonderful Flickr family. It's a pleasure to post here.

Mono Lake by Wayne Pinkston Via Flickr: Website, Instagram, Facebook Blend Sky: 16 images, 20 sec, f/2.8, ISO 6400, 14 mm Foreground: 5 minutes, f/2.8, ISO 1600, 14 mm Mono Lake, California. These are tufas arising out of Mono Lake. They are formed from mineral deposits from springs beneath the lake bed over centuries and are exposed when the water level falls. The water level varies greatly. The paths I recorded 2 years ago during the drought are mostly underwater now. The largest concentration of tufas is along the south shore. When including the Milky Way you are usually facing south, so this makes it more difficult to photograph the tufas, lake, and MW at the same time. There are a few small “peninsulas” that stick out into the lake making it possible (but tricky) to shoot across the water facing S and include both tufas and the MW. There is a stack for the sky and a long exposure for the foreground (5minutes), blended in PS. Cheers, Wayne Pinkston

Abandoned Cathedral by Wayne Pinkston Via Flickr: Website, Instagram, Facebook Inside an abandoned Cathedral in Madagascar. The red on the horizon is from fires. The local people burn the fields to clear them. There is no public electricity and so there is no light pollution from electric lights. 14 images stacked in Starry Landscape Stacker, 11 light frames, 3 dark frames, 14-24 mm lens at 24 mm, f/2.8, 15 sec, ISO 10,000.

King of Wings with Comet 252/Linear by Wayne Pinkston Via Flickr: This formation is called the King of Wings, and lies in the Badlands of New Mexico, south of Farmington, and north of Chaco Canyon. It is a "winged" hoodoo, and the massive eccentric wing is at least 30 feet, or 10 m long. You can easily walk under the wing. I am not usually claustrophobic, but every time I walked under it I had the feeling it would collapse on me, lol, so I qiuckly learned to walk around it. It has probably looked like this for millennia, but the eccentric weight on the rock must be tremendous. The camera was level, even thought the horizon does not look it. 14-24 mm lens at 19 mm, f/2.8, 20 sec., and ISO 12,800. Cheers, Wayne The small blue fuzzy object in the right center sky above the stone wing is the comet 252P/LINEAR. Thanks for taking the time to look.
