Prepare your cam to capture the Blood Moon

On 27 July 2018, South Africans can witness a total lunar eclipse, as the earth’s shadow completely covers the moon.

Also known as a blood or red moon, a total lunar eclipse is the most dramatic of all lunar eclipses and presents an exciting photographic opportunity for any aspiring photographer or would-be astronomers.

“A lunar eclipse is a rare cosmic sight. For centuries these events have inspired wonder, interest and sometimes fear amongst observers. Of course, if you are lucky to be around when one occurs, you would want to capture it all on camera,” says Dana Eitzen, Corporate and Marketing Communications Executive at Canon South Africa.

Canon ambassador and acclaimed landscape photographer David Noton has provided his top tips to keep in mind when photographing this occasion.   In South Africa, the eclipse will be visible from about 19h14 on Friday, 27 July until 01h28 on the Saturday morning. The lunar eclipse will see the light from the sun blocked by the earth as it passes in front of the moon. The moon will turn red because of an effect known as Rayleigh Scattering, where bands of green and violet light become filtered through the atmosphere.

A partial eclipse will begin at 20h24 when the moon will start to turn red. The total eclipse begins at about 21h30 when the moon is completely red. The eclipse reaches its maximum at 22h21 when the moon is closest to the centre of the shadow.

David Noton advises:

  1. Download the right apps to be in-the-know

The sun’s position in the sky at any given time of day varies massively with latitude and season. That is not the case with the moon as its passage through the heavens is governed by its complex elliptical orbit of the earth. That orbit results in monthly, rather than seasonal variations, as the moon moves through its lunar cycle. The result is big differences in the timing of its appearance and its trajectory through the sky. Luckily, we no longer need to rely on weight tables to consult the behaviour of the moon, we can simply download an app on to our phone. The Photographer’s Ephemeris is useful for giving moonrise and moonset times, bearings and phases; while the Photopills app gives comprehensive information on the position of the moon in our sky.  Armed with these two apps, I’m planning to shoot the Blood Moon rising in Dorset, England. I’m aiming to capture the moon within the first fifteen minutes of moonrise so I can catch it low in the sky and juxtapose it against an object on the horizon line for scale – this could be as simple as a tree on a hill.

 

  1. Invest in a lens with optimal zoom  

On the 27th July, one of the key challenges we’ll face is shooting the moon large in the frame so we can see every crater on the asteroid pockmarked surface. It’s a task normally reserved for astronomers with super powerful telescopes, but if you’ve got a long telephoto lens on a full frame DSLR with around 600 mm of focal length, it can be done, depending on the composition. I will be using the Canon EOS 5D Mark IV with an EF 200-400mm f/4L IS USM Ext. 1.4 x lens.

  1. Use a tripod to capture the intimate details

As you frame up your shot, one thing will become immediately apparent; lunar tracking is incredibly challenging as the moon moves through the sky surprisingly quickly. As you’ll be using a long lens for this shoot, it’s important to invest in a sturdy tripod to help capture the best possible image. Although it will be tempting to take the shot by hand, it’s important to remember that your subject is over 384,000km away from you and even with a high shutter speed, the slightest of movements will become exaggerated.

  1. Integrate the moon into your landscape

Whilst images of the moon large in the frame can be beautifully detailed, they are essentially astronomical in their appeal. Personally, I’m far more drawn to using the lunar allure as an element in my landscapes, or using the moonlight as a light source. The latter is difficult, as the amount of light the moon reflects is tiny, whilst the lunar surface is so bright by comparison. Up to now, night photography meant long, long exposures but with cameras such as the Canon EOS-1D X Mark II and the Canon EOS 5D Mark IV now capable of astonishing low light performance, a whole new nocturnal world of opportunities has been opened to photographers.

  1. Master the shutter speed for your subject 

The most evocative and genuine use of the moon in landscape portraits results from situations when the light on the moon balances with the twilight in the surrounding sky. Such images have a subtle appeal, mood and believability.  By definition, any scene incorporating a medium or wide-angle view is going to render the moon as a tiny pin prick of light, but its presence will still be felt. Our eyes naturally gravitate to it, however insignificant it may seem. Of course, the issue of shutter speed is always there; too slow an exposure and all we’ll see is an unsightly lunar streak, even with a wide-angle lens.

 

On a clear night, mastering the shutter speed of your camera is integral to capturing the moon – exposing at 1/250 sec @ f8 ISO 100 (depending on focal length) is what you’ll need to stop the motion from blurring and if you are to get the technique right, with the high quality of cameras such as the Canon EOS 5DS R, you might even be able to see the twelve cameras that were left up there by NASA in the 60’s!

AppDate: Prepare for space

In this week’s AppDate, SEAN BACHER highlights Space Nation Navigator, Hitman Sniper, Snake Mask, Memrise, WhatsApp Web, and Carrot Weather.

Published

Space Nation Navigator

Space Nation Navigator is a bit of a strange app. It is part game, part exercise and part educational. On the game side, users have to navigate the Mars Rover, put the International Space Station back into orbit or move their Martians to safety before a sand storm hits Mars. When it comes to exercise, Space Nation Navigator provides users with a range of exercises and Yoga videos to prepare them for space travel and working in an anti-gravity environment. The education aspect teaches users about the planets, and star constellations, and then offers quizzes on what has been taught.

Platform: Android and iOS

Cost: A free download.

Stockists: Visit the store linked to your device.

 

Memrise

Memrise takes a new approach to help people learn new languages. Instead of providing a user with random phrases and words to memorise, the app connects you with a person already fluent in the language you want to learn. In turn, the person you are speaking to wants to learn the language in which you are fluent. Once your profile is filled out and languages selected, it connects you with people around the world who are interested in your language, and then allows you to chat with them in real-time. Memrise also lets one learn new languages through games, chatbots and grammarbots that help with spelling, tenses and pronunciations.

Platform: Android and iOS

Cost: A free download.

Stockists: Visit the store linked to your device.

 

Hitman Sniper

Hitman Sniper is loosely based on the Agent 47 movie released a few years ago. The game offers players the ability to hone their shooting skills through a range of training courses and, once they think they are ready, they can start taking out the bad guys. Things start off easy enough, but they get more and more difficult as one progresses through the 150 missions on offer. One will also have to upgrade various gun components, like scopes, magazine capacities and silencers, to make the missions a little easier. Hitman Sniper lets users buy 16 to tackle each of the missions – either with real money or via the points accumulated by completing missions. Money and points can also be used to upgrade firearms.

Platform: Android and iOS

Cost: R7 – with a range of in-app purchases.

Stockists: Visit the store linked to your device.

 

Snake Mask

The iconic Snake game that was preinstalled on most older Nokia phones has had a complete make-over. It now uses Facebook’s AR technology, meaning that you have to navigate the snake around obstacles in your home or office, all the while collecting coins and stars that change the snake’s speed and length. Unfortunately, Snake Mask is only available on Nokia’s new range of smartphones. However, it should not take long before it slithers onto other devices.

 

Platform: New Nokia smartphones running Android.

Cost: Free to use through the Facebook app installed on the device.

Stockists: Available through the Facebook app.

 

WhatsApp Web

Although this is by no means a new app, it is an extremely useful one, and one that not many people know about. Tapping out WhatsApps on your phone is easy enough, but thanks to WhatsApp Web it can be even easier. Open the WhatApp Web page under WhatsApp and you will see a QR code. Scan this code through WhatsApp on your mobile and you will be shown a replica of what you would normally see on your phone. You can then type and reply to messages using your computer instead of having to stop everything and unlock your phone every time a message comes through. WhatsApp Web is great if you share your computer with other people as it automatically disconnects when the browser is closed. However WhatsApp also offers an app that when installed will stay connected to your phone unless you manually remove it.

 

Platform: Any up-to-date Internet browser

Cost: Free to use and install

Stockists: Visit www.WhatsApp.com

 

Carrot Weather

There are thousands of weather apps on the Internet these days and all of them do the same thing – inform you of the weather in your area. However, Carrot Weather has taken what is just another app and turned it into something fun. By fun, I mean sarcastic, rude and completely politically incorrect. A user starts off by selecting religious and political views. It then asks about personality, ranging from friendly to homicidal to overkill – which includes profanity. So, for instance, instead of waking up to to the standard partly cloudy forecast, Carrot Weather will display something like: “It’s only partly sunny, the sun is a total effing failure.” It also has a range of insults that it throws at you whenever you open the app – some of them downright insulting, so it is definitely not for those who are easily offended. The app’s user interface is very simple, displaying a week’s daily forecast and hourly forecasts for the day selected.

Platform: Android and iOS

Cost: Free to download but with adverts. The premium, advert free version costs R12 per month.

Stockists: Visit the store linked to your device.

SA Start-up reinvents PABX

For any South African business, the idea of setting up or changing a telephonic switchboard system is the stuff of nightmares. Dealing with expensive hardware and hearing things like QSIG and VOIP is not what you’d call exciting.But now there is an app.

Published

on

Enter BuzzBox (www.buzzboxcloud.co.za), a web-based telephone switchboard that is aimed at small and medium sized businesses wanting to take the hassle and cost out of the company switchboard. Whether you are a small one-man operation or a larger organisation with staff working remotely, BuzzBox is the best switchboard solution.

What sets BuzzBox apart from anything else on the market is its easy-to-use dashboard. It puts you in control of everything from picking your phone number to setting up voice prompts and managing your business-hours schedule.

BuzzBox was developed when the startup behind it, Jini-Guru, needed such a service for its own use across multiple continents. “When we started Jini-Guru we could not find a seamless online process that would allow us to set up a full web-based switchboard, so we decided to build one for ourselves,” says Mike Smits, Director at Jini-Guru.

He says a lot of startups today are tech savvy and know how to use apps and the services that go with it. “It’s the uberisation of services and its driving demand for instant service activation.”

BuzzBox works as an app on both iOS and Android but users wanting a desk phone option can choose from a variety of devices on offer or use their existing VOIP phones.

Setting up a BuzzBox account takes 5 minutes. During registration your FICA documents are uploaded [ID and proof or residence] and you get to pick your phone number before the account is created. Companies that want to keep an existing number can do so too.

The real magic happens when you log on to the BuzzBox Dashboard. The main screen displays a summary of statistics for your account while the left-hand menu provides you quick access to various configuration settings and reports.

Setting up new extensions or external numbers is done with a few clicks and you can even set up various departments which is a great way to route a call to various people in a department, like sales or support.

The intuitive user interface also makes it easy to set up hold-music and voice prompts. You can add voice prompts by recording them straight to your phone, just make sure you use a clear voice with quiet surroundings for the best customer experience.

One of the main features of BuzzBox is its call recording feature that allows an organisation to record calls for legislative purposes, such as a lawyer, or for customer service purposes such as support. Recordings are stored securely online, and you have the ability to download recordings for playback. Companies can opt-in for this service and it’s free to use. Recordings are stored online and are fully encrypted so only you can listen to, or download them. Storage costs R1 for every 1000 minutes of stored recordings.

Other features include call forwarding and scheduling. The latter allows you to set office hours for your organisation which will divert calls to an after-hours messaging service. You also have the option to enable routing to an employee who is on call after hours.

BuzzBox also has a reseller program for companies wanting to offer this as a switchboard solution to their existing customers.

The costs for this service is R89 p/m for the first phone number which includes your first extension for free. Thereafter you’ll pay R89p/m per extension. Calls between extensions are free but you pay per second for all outgoing phone calls. More info on pricing can be found here: https://buzzboxcloud.co.za/pricing/

BuzzBox is offering a Launch promotion where they are offering the first line and extension free for 12 months. Only pay for calls. Use promo code “feoifyaa” during sign-up to apply your discount.
