Last Meeting of the Season – Gear Swap

Wow. It’s almost gone already, our 60th season! Who would’ve thought back in September of 1956 that this little ole photography club would still be around. And our last meeting of the season is fast approaching – Tuesday, June 6, 2017.

Just a reminder to members that we will have a gear swap from 6:30 till 7 at the next meeting. Bring in your un-wanted, no-longer-needed photography equipment and see what you can get for it. Members looking to score some gear are encouraged to bring a full wallet.

The Twilight Zone – A Guest Post by Julian Delf

As our next assignment is “Dusk to Dawn” I thought it might be interesting to look at dusk and dawn and how they relate to sunset, sunrise, twilight and the golden and blue hours. We will look specifically at dusk, dawn is just the reverse.

So, we might think dusk is some time around sunset to when it gets dark, but there is a precise scientific definition of what it is. Contrary to what we might think dusk isn’t actually a period of time, it is a point in time. To make things slightly more complex there is more than one level of dusk. In looking at the definition we need to consider events related to the “true horizon”. At many locations the true horizon is obscured by trees, buildings, mountains, etc., and the resulting intersection of earth and sky is called the “visible horizon”.

So, the first event to consider is sunset, this is the time at which the trailing edge of the Sun crosses the true horizon. When the Sun is low to the horizon the atmosphere refracts the light, which means the Sun may still appear to be on the horizon when it has actually already set. After sunset we enter “Civil Twilight”. This continues until the centre of the Sun is 6º below the true horizon and this is the point of “Civil Dusk”. From this point on we are in “Nautical Twilight” until the centre of the Sun is 12º below the true horizon and this is the point of “Nautical Dusk”. After this we move into “Astronomical Twilight” and that continues until the centre of the Sun is 18º below the true horizon and this is the point of “Astronomical Dusk”. After this point we are in Night, this continues until the Sun has risen to 18º below true horizon and this is the point of “Astronomical Dawn” and we follow the same steps e.g. “Astronomical Twilight” to “Nautical Dawn”, etc.

When we look at the times these events occur and how long they last, it gets a bit tricky as the path of the Sun depends on our Latitude and the time of the year as these change the angle the Sun rises and sets. If we look at our next meeting (6th June) we have :

Sunset 21:05, Civil Twilight length 37min, Civil Dusk 21:42, Nautical Twilight length 48min, Nautical Dusk 22:30 Astronomical Twilight length 60min, Astronomical Dusk 23:30 – start of Night

There are many websites that show these times over the year, a good one is :

https://www.timeanddate.com/sun/canada/owen-sound

The changes in the position and path of Sun also affect the photographic Golden Hour and Blue Hour. As well as the Sun’s position these hours are also dependent on the local weather and atmospheric conditions. Unlike the descriptions above these don’t have precise technical description and there are a few different interpretations of how to calculate them.

The Golden Hour, or Magic Hour, relates to a period sometime before sunset till sunset, or just after sunset. If we use the information from the site http://www.golden-hour.com/ then it is taken as the time the Sun is 6º above the horizon till sunset. A different site uses an end point of the Sun being 4º below the horizon. Looking at the timings for 6th June we have :

Evening Golden Hour Starts (6º above the horizon) 20:21, ends (sunset) 21:05, duration 44mins. The Blue Hour relates to a period where the golden light has ceased and the light is mainly blue. In this example it is taken from near the end of Civil Twilight to near the end of Nautical Twilight, a good site for Blue Hour information is http://www.bluehoursite.com/. Looking at the timings here for the 6th June we have :

Night Blue Hour Starts 21:27, ends 22:17, duration 50mins

However other sites may give different timings based on different calculations. There is a matching “hours” in the morning. Below is a graphic that shows all the above points.

Next Meeting at the Library

Our next meeting will be at the Owen Sound and North Grey Union Public Library on March 7, 2017, located at 824 1st Ave West. Please note that the start time will be at 6:30 instead of 7 so be sure to come earlier.

We had planned to have Willy Waterton at the February meeting but due to the threat of freezing rain, we asked Willy if he could make it for March instead, and he graciously agreed. We will have our usual slideshow of the monthly assignment, which is Frozen for this month, and some other usual things to take care of, but then Willy will speak to the audience about photography.

Willy is a local photojournalist from Kemble and was a staff photographer for the Owen Sound Sun Times for many years. He’s been as far as Antarctica in his travels and his years of experience has produced fantastic imagery. You can see many of his photos from around the Grey Bruce area on his Instagram feed at http://www.instagram.com/willywaterton.

The 2016 OSCC Picnic

On June 12 we had our annual Camera Club Picnic. This has become a new tradition in recent years and is a great way to reflect on the past season. It gives those in attendance (spouses and partners are welcome to the picnic) an opportunity to socialize and “talk shop”, something we don’t get enough time for at the regular meetings.
This year we met at Inglis Falls where Lynn Reket greeted members with the categories for a photographic scavenger hunt. This is always fun. The idea is to go out and capture your interpretation of each category. The categories this year were “Go With the Flow”, “Stoned (Rocks can be included)”, “Structure”, “Bloom Where You Are Planted”, and “A Tree-mendous Shot”. There were a lot of jokes around that second one.

Once the members got their five photos we met at the Grey Sauble Conservation Authority where Randy, the club’s President, had the barbecue fired up and salads and desserts were aplenty.
Greg put all the photos from the members’ cameras on his laptop and projected them on a screen where we went through them and each member spoke about why they composed the photos the way they did and what they learned on the shoot. Before Randy went to prepare the barbecue, he was able to play paparazzi and capture some of the members as they worked on their scavenger hunt. These photos were also presented in a slideshow while Randy said a few words to wrap up the proceedings.
A great time was had by all and a big thanks to those who helped organize the event, brought food, and to Lynn Reket for preparing the scavenger hunt.
