13 steps to perfect snapping

Published

LG’s latest flagship smartphone, the G5 gives users the opportunity to fully experience the joy of photography. Here are 13 ways to get you snapping like a pro.

Cartier-Bresson is widely regarded as one of the greatest photographers of all time and once said, “To photograph is to hold one’s breathe, when all faculties converge to capture fleeting reality. It’s at that precise moment that mastering an image becomes a great physical and intellectual joy.”

Here are 13 ways to get you snapping like a pro, provided by LG:

1. Accessing the manual mode

One of the best ways to start capturing those significant moments with the LG G5 is by accessing the manual mode.  To access the manual mode, you’ll have to tap the 3-dot icon at the top-left of the screen, which brings up the three main modes: Simple, Auto and Manual.

The manual mode allows you to control the white balance, focus, exposure, ISO, shutter speed and AE-L.  The white balance allows you as the user to alter the colour tone, compensating for unnatural lighting or to create skewed colour effects.

The purpose of the ISO is that it determines the sensitivity of the sensor. When choosing darker environments to take pictures, you will need to use a higher setting. The AE-L, locks the exposure, letting you use the light level as a creative effect, making shots either much brighter or darker than the G5 would normally use.

2. How to use manual mode to get noise free shots

All you’ll have to do is set the ISO to 200 (it goes down to ISO 50), then use the shutter speed control to see how slow you need to go for low-noise results. The benefit of using the G5 is that it has optical image stabilisation (OIS), you can make the shutter go fairly slow and still get sharp photos.

3. Shooting RAWs

RAW files are what you get when you take the ‘raw’ information from a camera sensor, before reducing the noise level and smoothing things out. Using RAWs allows you to do your own processing, often ending up with a finer detailed image.

The G5 allows you to shoot RAWs by simply accessing the manual mode and tapping the second icon from the bottom of the screen, over on the left column. This will allow for the shooting of RAW and JPEG files, rather than just JPEGs. RAWs come out as a file known as DNG (Digital NeGative file).

4. Using the second camera as “zoom out”

The G5 has dual cameras (16 MP f1.8 main camera has 78-degree angle view and the 8MP additional camera captures a 135-degree super wide-angle image) to take your digital photograph to the next level. It has a new, unique feature like pop – out photo, capturing more with the zoom out.

In the camera app you can switch between lenses via a button, and when using the digital zoom the camera switches seamlessly between the two modules. The autofocus is assisted by a laser that measures the subject distance.

5. Use the main camera for the best image quality

The 16MP wide angle camera of the LG G5 is the best Android camera on the market giving users a fish-eye effect in every shot. What it means for the users is that the camera allows you to fit much more of the scene into a single photo.

6. Changing photo and video resolution

Should users want to play with different size images for that perfect selfie, they can switch to 4:3 or 1:1 images by tapping on the cog icon at the bottom-left of the screen and selecting the top option in the menu that pops up.

As well as changing the shape of photos, they can also alter the video resolution.  The G5 normally shoots 1080p video users can level-up to UHD (the exact resolution of ‘4K video’).

7. Video stabilisation

For that perfect steady shot users can find the option for video stabilization near the bottom of the camera settings menu, which you access by tapping the cog icon. Tapping on this flicks between SteadyShot stabilisation and OIS, if you’re using the standard camera lens in Auto mode.

The former is what most phones use, a digital enhancer that uses the edges of the frame as a buffer to smooth-out any movements. This leaves you with a slightly more ‘zoomed-in’ view than you get when taking photos. That’s one reason why you might use OIS instead, which uses the little camera stabilisation motor to keep your footage smooth.

8. Simple mode is great for simple photography

Simple mode is found by tapping the 3-dot icon at the top-left of the camera app.

Simple mode takes away almost all custom features you get with the other options. All you do is tap on the object on which you want to focus and the LG G5 camera app both focuses and takes a shot as quickly as possible.

9. Shortcut key for instant photos

In the main phone Settings menu, go to the General tab and then select Shortcut key. In here you’ll see a flick switch for Quick Shot. Make sure it’s switched on. This lets you press the volume down button twice quickly when the phone is off to fire-up the camera and take a photo.

10. Timelapse + wide-angle camera = cool movies

The G5 has several ‘creative’ modes in its camera app and Time Lapse is one of the more interesting ones. This shoots video, but at 1/15 the normal speed. That means it takes two frames a second rather than the usual 30.

Use this with the wide-angle camera and you’ll get footage that resembles some of the stuff GoPros are used for in action sport footage.

11. Use the grid display for landscape photography

The G5 has a grid option to stop those uneven photos and help you align or center pictures properly. What it means for the user is that you get another reference point of where to line-up the horizon, as well as helping you work out what you want the focus of the picture/image/photo to be.

You’ll find Grid at the very bottom of the camera app Settings menu, accessed by tapping on the cog icon.

12. Use 30sec exposure to make something special

The G5 can keep its shutter open for up to 30 seconds.  What it means for the user is that it merges all the light information from that half-minute stint into a single image.

What one can do while using the 30sec long-exposure photography is shoot a road where car lights turn into streaming neon lines, and create noise-free night shots that almost look like daylight photos.

13. 360 Cam

The G5 is the only Android smartphone on the market that comes with a series of module accessories (Friends) that fit onto its bottom and one in particular where users have been raving about is the 360 Cam.

The LG 360 CAM provides 2K video and 5.1 surround channel recording on three microphones to help users effortlessly create high-quality 360-degree contents. Having secured a partnership with Google, images taken with the 360 CAM can be uploaded to Google Street View and YouTube360, adding the fun of sharing creative content with others.

Money talks and electronic gaming evolves

Computer gaming has evolved dramatically in the last two years, as it follows the money, writes ARTHUR GOLDSTUCK in the second of a two-part series.

The clue that gaming has become big business in South Africa was delivered by a non-gaming brand. When Comic Con, an American popular culture convention that has become a mecca for comics enthusiasts, was hosted in South Arica for the first time last month, it used gaming as the major drawcard. More than 45 000 people attended.

The event and its attendance was expected to be a major dampener for the annual rAge gaming expo, which took place just weeks later. Instead, rAge saw only a marginal fall in visitor numbers. No less than 34 000 people descended on the Ticketpro Dome for the chaos of cosplay, LAN gaming, virtual reality, board gaming and new video games. 

It proved not only that there was room for more than one major gaming event, but also that a massive market exists for the sector in South Africa. And with a large market, one also found numerous gaming niches that either emerged afresh or will keep going over the years. One of these, LAN (for Local Area Network) gaming, which sees hordes of players camping out at the venue for three days to play each other on elaborate computer rigs, was back as strong as ever at rAge.

MWeb provided an 8Gbps line to the expo, to connect all these gamers, and recorded 120TB in downloads and 15Tb in uploads – a total that would have used up the entire country’s bandwidth a few years ago.

“LANs are supposed to be a thing of the past, yet we buck the trend each year,” says Michael James, senior project manager and owner of rAge. “It is more of a spectacle than a simple LAN, so I can understand.”

New phenomena, often associated with the flavour of the moment, also emerge every year.

“Fortnite is a good example this year of how we evolve,” says James. “It’s a crazy huge phenomenon and nobody was servicing the demand from a tournament point of view. So rAge and Xbox created a casual LAN tournament that anyone could enter and win a prize. I think the top 10 people got something each round.”

Blockchain unpacked

Blockchain is generally associated with Bitcoin and other cryptocurrencies, but these are just the tip of the iceberg, says ESET Southern Africa.

Published

on

This technology was originally conceived in 1991, when Stuart Haber and W. Scott Stornetta described their first work on a chain of cryptographically secured blocks, but only gained notoriety in 2008, when it became popular with the arrival of Bitcoin. It is currently gaining demand in other commercial applications and its annual growth is expected to reach 51% by 2022 in numerous markets, such as those of financial institutions and the Internet of Things (IoT), according to MarketWatch.

What is blockchain?

A blockchain is a unique, consensual record that is distributed over multiple network nodes. In the case of cryptocurrencies, think of it as the accounting ledger where each transaction is recorded.

A blockchain transaction is complex and can be difficult to understand if you delve into the inner details of how it works, but the basic idea is simple to follow.

Each block stores:

–           A number of valid records or transactions.
–           Information referring to that block.
–           A link to the previous block and next block through the hash of each block—a unique code that can be thought of as the block’s fingerprint.

Accordingly, each block has a specific and immovable place within the chain, since each block contains information from the hash of the previous block. The entire chain is stored in each network node that makes up the blockchain, so an exact copy of the chain is stored in all network participants.

As new records are created, they are first verified and validated by the network nodes and then added to a new block that is linked to the chain.

How is blockchain so secure?

Being a distributed technology in which each network node stores an exact copy of the chain, the availability of the information is guaranteed at all times. So if an attacker wanted to cause a denial-of-service attack, they would have to annul all network nodes since it only takes one node to be operative for the information to be available.

Besides that, since each record is consensual, and all nodes contain the same information, it is almost impossible to alter it, ensuring its integrity. If an attacker wanted to modify the information in a blockchain, they would have to modify the entire chain in at least 51% of the nodes.

In blockchain, data is distributed across all network nodes. With no central node, all participate equally, storing, and validating all information. It is a very powerful tool for transmitting and storing information in a reliable way; a decentralised model in which the information belongs to us, since we do not need a company to provide the service.

What else can blockchain be used for?

Essentially, blockchain can be used to store any type of information that must be kept intact and remain available in a secure, decentralised and cheaper way than through intermediaries. Moreover, since the information stored is encrypted, its confidentiality can be guaranteed, as only those who have the encryption key can access it.

Use of blockchain in healthcare

Health records could be consolidated and stored in blockchain, for instance. This would mean that the medical history of each patient would be safe and, at the same time, available to each doctor authorised, regardless of the health centre where the patient was treated. Even the pharmaceutical industry could use this technology to verify medicines and prevent counterfeiting.

Use of blockchain for documents

Blockchain would also be very useful for managing digital assets and documentation. Up to now, the problem with digital is that everything is easy to copy, but Blockchain allows you to record purchases, deeds, documents, or any other type of online asset without them being falsified.

Other blockchain uses

This technology could also revolutionise the Internet of Things  (IoT) market where the challenge lies in the millions of devices connected to the internet that must be managed by the supplier companies. In a few years’ time, the centralised model won’t be able to support so many devices, not to mention the fact that many of these are not secure enough. With blockchain, devices can communicate through the network directly, safely, and reliably with no need for intermediaries.

Blockchain allows you to verify, validate, track, and store all types of information, from digital certificates, democratic voting systems, logistics and messaging services, to intelligent contracts and, of course, money and financial transactions.

Without doubt, blockchain has turned the immutable and decentralized layer the internet has always dreamed about into a reality. This technology takes reliance out of the equation and replaces it with mathematical fact.
