LETTER FROM DAVID SPELTZ
Dear NHSPA Members
As many of you know, the Exeter show was inspirational and a pleasure to visit. So many of our photographer members hung their best in the gallery, and the comments showed. The presentation and talks were well attended and always enjoyed. Which brings me to a suggestion that several have mentioned and I want to pass on. Would those of you who put so much time into preparing your talk be willing to do it again at our annual meeting in May? Think about it as you read on.
Our annual membership meeting is Friday, May 2 to Sunday, May 4 this year. As our email blast last month mentioned, it will be at the AMC’s Highland Center in the White Mountains (see details below). If you are planning to attend, and if you have not booked your stay, be sure to soon. The only cost is your room and board (as described below). Or just come for the day on Saturday. There is no fee.
The NHSPA board met February 2 in Exeter as the NHSPA show closed. Here are some highlights , but I will start with the annual meeting.
The weekend will be in the AMC Highland Center in Bretton Woods. We are fortunate to have, as our guest speaker on Saturday afternoon, Tony Decaneas, owner of Decaneas Archive - http://www.decaneasarchive.com/index.htm. (You may have know Decaneas Archive when it was Panoptican). Tony has a large collection of Bradbury Washburn photographs and will be discussing this collection in, of course, the AMC Washburn Gallery at Highland Center.
We are seeking (and this is where our Exeter show presenters come in) other talks. If you have a talk or presentation you would like to volunteer, please let us know. Some ideas have included leading trail walks and a mushroom hunting walk. Email David Speltz, email@example.com with the subject if you wish to volunteer. As of now, David Speltz bhas volunteered to teach basic astro-photography - photographing planets, deep sky objects, and of course, the moon, with some guidelines on how to understand the night sky. We will have telescopes on hand to use visually and for astro-photography, weather permitting.
We also plan to have a period where we can share your photographs.
The Board is reviewing over the next few weeks possible changes to the bylaws. Bylaw changes must be presented at least three weeks in advance to the membership so, assuming we meet the deadline, look for those by or before early April.
Barb Zulkiewicz reported on a successful Star Island retreat. Star Island has been booked again for the long weekend September 4-7, 2014.
Sarah Flause reported that the website (NHSPA.org) is up and running with access for members to run their galleries. She will provide a full report on progress, as well as the Treasurer’s report.
Two board members (Nevin Brown and David Speltz) have terms ending. Nominations are open. Please email Paul Wainwright, secretary, with nominations). Paul’s email is firstname.lastname@example.org.
INFORMATION FROM NORA VRUBLEVSKA ON NIGHT PHOTOGRAPHY
Here are some follow-up Materials from Nora Vrublevska's Talk on Night Photography at our last members meeting in Exeter, reformatted to work in this text-only format.
These are the titles and links to the two timelapse videos Nora wanted to share in the classroom, but was unable to due to lack of Wifi connection. She says "Both of these timelapses are quite new and are just absolutely amazing, and are such an inspiration for me to keep shooting":
"Nightvision" by Luke Shepard (https://www.youtube.com/watch?v=fb4dpcIYTrc)
"Light Goes On" by Darren Pearson (https://www.youtube.com/watch?v=Z1Uw-lBuzIg)
Tools needed for NPy:
- Camera with bulb setting
- Wide to normal focal length lens (fixed = best)
- Cable release or remote shutter release (preferably intervalometer)
- Tripod (ballhead vs pan/tilt)
- Extra batteries for camera
- Penlight or small flashlight (no headlights)
- Lens hood and black card
... and these are optional:
- More powerful flashlight for light painting (incandescent, LED different color temperatures)
- Portable flash with gels
- Any other portable light sources (Christmas lights, EL wire, orb tools, light writers, zippo, steel wool, etc.)
- Smartphone with night sky apps
Digital Camera Settings:
- Set your camera to RAW
- Use your camera's Native ISO for best quality, high ISO to freeze motion*
- Bulb setting for shutter
- Choose aperture (f/8 to start with)
- White Balance (AWB or 25003000K for urban and 4000k for moonlight)
- Long Exposure Noise Reduction (On or Auto)
- Turn LCD display brightness down
- Turn on "blinkies" highlight clipping indicator on photo playback
- Turn off any JPEG specific settings (e.g. picture styles, Dlighting)
- Turn off image stabilization (IS)
High ISO Testing for Night Photography
Night exposures (especially by moonlight) should usually be taken at your camera's native ISO (to minimize noise), and can be very long. Light meters are not reliable in the dark and we need a better way to determine the proper exposure for a photograph at night. Photographic reciprocity dictates that there are 6 stops between 1 second and 1 minute (64 seconds, to be exact). Because of this, there is an easy way to make high ISOs test exposures that require only N seconds, and know that equivalent low noise exposures using native ISO can be made in N minutes.
Specifically, an exposure using "High ISO", your test aperture, and a shutter speed of X SECONDS will result in an image with the same histogram as an exposure using "Native ISO", your final aperture, and a shutter speed of X MINUTES (per the details below).
With all this in mind, you can take a test exposure at high ISO, make any necessary adjustments if the image/histogram seems too dark or too bright, and when a good test exposure is achieved, make the final exposure at your camera’s native ISO. Please refer to the details below to determine what your highest ISO settings are. For example, if your camera’s native ISO is 100 and it goes up to ISO 6400: with a test shot at ISO 6400, f/8, and 10 seconds, the final exposure will be ISO 100, f/8, and 10 minutes.
For Cameras with Native ISO of 100:
If your highest ISO is 6400, use your final aperture as your test aperture.
If your highest ISO is 3200, use your final aperture plus one stop more open as your test aperture.
If your highest ISO is 1600, use your final aperture plus 2 stops more open as your test aperture.
For cameras with Native ISO of 200:
If your highest ISO is 12800, use your final aperture as your test aperture.
If your highest ISO is 6400, use your final aperture plus one stop more open as your test aperture.
If your highest ISO is 3200, use your final aperture plus 2 stops more open as your test aperture.
If your highest ISO is 1600, use your final aperture plus 3 stops more open as your test aperture.
500 divided by focal length = the longest exposure before stars start to trail
for example, if you have a 24mm lens on a full frame camera, the longest exposure before stars start to trail is 20 seconds
500 ÷ 24 = 20.834
However, if you have a 24mm lens on a crop sensor camera, you’ll have to multiply your focal length by crop factor first (1.5 or 1.6, depending on camera), thus the longest exposure is 13 seconds
24 * 1.5 = 36
500 ÷ 36 = 13.889

From Gary Lamott:
I have been working with the folks at Topaz Labs for several months.
I am very honored that they have featured my photographs on their Blog or their Facebook page for all of their monthly promotions since October.
They will be using my photo “Island in the Sky” for their February Ad in Photoshop User Magazine.
You can view the image and the Tutorial on their Facebook page and on Youtube as well.
In the February Ad there will also be a web link for the promotion.
A copy of this photo is currently on display in Congresswoman Carol Shea Porter's Manchester Office as part of her Art on Loan Program.
From Richard Moore:
Richard Moore’s “twice-seen” images were featured on WMUR’s NH Chronicle, on February 7 and can be seen online after the broadcast.
From Michael Sterling:
First if I can toot my own horn, some of my photos are displayed in the "permanent collection" of the Optima Bank in Portsmouth and the Exeter Chamber of Commerce.
Second, many people don't know that there is a B&H channel on YouTube. It contains videos of the 1 hour seminars held at their location. They are subtle informercials. But, most of the content is interesting and the presenters are generally good. It's not just about equipment - some also deal with creativity. Here's the link:
From David J. Murray
The Greater Portsmouth Chamber of Commerce has licensed 75 of my Portsmouth area images for use on their new tourism web site, and the Port Inn in Portsmouth has 15 of my area images on permanent display as large framed prints in their newly renovated lobby and adjacent public spaces.
