Wireless Technology in Photography

Reminiscing about articles I wrote back in 2013 (like that previous article I reproduced here) I came across this one too, I've been preaching this wireless gospel for quite some time. So, just in case the site goes down, here are those thoughts once more. 


Wireless tech is steadily invading all facets of life, from the office, to the home, and now even onto non-traditional applications. Anywhere Digital Data needs to be transmitted, people are finding new and innovative ways to use wireless tech. The scope keeps increasing as data speeds becomes faster and more reliable.

Digital data transfer has a long history in photography. Starting with things like unhooking the studio lights and flashes from long trailing cords, todays sophisticated systems transmit even information like distance and colour temperature between cameras and flash units. Pro photogs benefited by using what was referred as tethering, where pictures taken on the camera was instantly transmitted to a computer with a high quality display, meaning parties involved with shoots, such as clients or models can immediately see the images being produced and provide feedback if it is meeting expectations. Early systems were cumbersome and expensive, and more importantly, wired, which created lots of clutter. Early wireless adapters provided by camera makers were expensive, and functionality was limited to transferring the image files only.

Last year, Canon released the EOS 6D, aimed at providing a “cheap” way for new users to enter the Full Frame market. I say “cheap”, as the camera still costs US$2000. However, the 6D represents a very important step in Digital Photography. It is the first, and at the time of writing, the only camera to provide onboard GPS and Wifi. And the capabilities provided are more than just transferring the files back to a server, it provides mobile apps that allow the photographer to use a tablet or smartphone to connect directly to the camera (using WiFi Direct, no need for a WiFi Router), and control functionality on the camera. This means not just viewing the results, but the full functionality of changing focus, aperture, shutter speed, ISO and many other functions will be controlled by the app, and the photographer will have a live view of the image that the camera is seeing even when physically away from the camera.

But again, as exciting as these capabilities are, the startup cost is quite large. Even in this country, with its ridiculous price structures, one can buy a functioning car for that kind of money. So what kind of options exist that are less severe on the wallet? At the low end of the range, a photographer can buy something like an Eye-Fi card. This will allow image backup from any camera that can use a SD card to a computer, and the computer software will allow the image to be viewed immediately. Limited, but something, and the price point can range between $40 and $100. Some cameras have adapters that will allow the same functionality, Canon’s latest offerings even coming in the form of a grip with additional shutter buttons and some remote functionality, but costing $700 or thereabouts. Also, they tend to limited to certain camera models only.

This brings us to the device I want to focus on. Its called the CameraMator. The website can be found at http://www.cameramator.com and the kickstarter page from which they raised the funding which has a pretty full description of its capabilities are right here – http://www.kickstarter.com/projects/urashid/cameramator-wireless-tethered-photography

I’ll just summarize the highlights here. The main functionality is the ability control aperture, shutter speed, ISO and white balance remotely, and instant photo review. In addition, it will allow a self timer, an Intervalometer and HDR Bracketing capabilities. It works with a wide range of cameras, a distinct point in its favour. And so is the price, at a mere $300, it costs less than ½ of what a unit produced by the camera manufacturers will cost. Its certainly running very close to providing the WiFi functionality in the $2000 Canon 6D.

Earlier, I pointed out why photographers shoot tethered. Instant feedback on larger, better quality screens than those on the backs of DSLRs, client feedback, model interaction, the ability to show what is happening over what you want without moving the camera.  The remote capability could be useful for wildlife, leaving the camera covering a remote scene and shooting from far so as not to spook the animals. It would allow the photographer to minimize risk to himself by keeping the camera somewhere risky why shooting it from a safe distance, like keeping the camera right near the track at a motor racing event. However this kind of work is typically the province of professionals who get paid big bucks to shoot. The ability to get the camera into all kinds of angles and still compose the images accurately. Hold the tripod over your head for a shot looking down from 10 feet, shoot at ground level without having to lie on the ground to look through the viewfinder. Shoot from the next room, if that suits your fancy.

Why would an average DSLR user want to buy something like this? With this kind of capability, lets see what we can add. Self portraits, accurate framing, and accurate timing for the picture. Its a lot more cost effective for experiments than hiring a professional model. No more guessing if there is enough space once you put the timer on and run to be included in a group shot. Much better image quality for live blogging. no need for blurry grainy photos from a Mobile, use the high ISO and wide apertures available and upload directly to the web. Have a team of photographers sending pictures straight to a laptop for instant review and upload to the net. Share pictures instantly with attendees at parties, sending pictures direct to their smartphones. This kind of technology certainly increases the business potential of your DSLR. The possibilities seem limited only by imagination.

Samsung Galaxy Camera

Back in 2013 I wrote an article for TechWire on the Samsung Galaxy Camera. With the launch of the Canon R5 and R6 I wanted to revist it, but it appears the site has been hijacked - So had to retrieve it from the Google Cache
https://webcache.googleusercontent.com/search?q=cache:Sl2trNwg3rsJ:https://techwire.lk/samsung-galaxy-camera-in-focus/+&cd=19&hl=en&ct=clnk&gl=lk

However, since I don't want to the article to be lost in case the site can't be recovered, I wanted to publish it here.

The Samsung Galaxy Camera is an interesting product. It’s not a particularly revolutionary device, by which I mean, its not going to claim first to market on its head line features. It is not the first Android powered pure camera (Nikon holds that title) and its also not the first pure camera with wifi/wireless data connectivity. Even Samsung has several models in its stable with wifi connectivity. It is probably the first camera to feature 3G/4G connectivity on board, but phone cameras have been doing that for years. There are also plenty of cameras on the market with GPS sensors onboard.
What the Galaxy Camera does have is a compelling mix of features. Android as an Operating System has a pretty powerful set of applications for image editing, such as Photoshop Touch. Samsung already has experience in this arena, Photoshop Touch is one of the pre-loaded apps on the Galaxy Note 10, which is a pretty formidable mobile editing platform with its 10 inch screen and S-Pen, which has Wacom technology.
Galaxy Camera Editing
The device on the Hardware side is pretty much equivalent to the Galaxy SIII, using the same screens, CPUs and graphics processors. What this means in real world terms, is that any software development on the SIII (currently Samsung’s flagship, so commanding the maximum support from Samsung’s development resources) will technically be portable to the Camera with little effort. So it should be in line for updates right at the top of the tree. It beats the Nikon S800C Android camera in having Android 4 on board as shipped, compared to the Nikon’s 2.3 Gingerbread flavour.
On the Camera side, the sensor used is larger than a standard phone camera sensor, the lens is pretty decent with a f2.8 aperture at its widest, and covering a zoom range that covers the 35mm equivalent of 23mm to well over 400mm. This is a lot more than what was classed as superzoom compacts just a few short years ago. (Not currently, Canon’s current superzoom is a 50x zoom, 24-1200mm equivalent). The camera controls offer a decent amount of manual control. It has some innovative smart modes which will makes things easier for photo enthusiasts who want a certain effect, but don’t know manual controls get that effect manually.
Along with the good, there is a couple of bad. First up, lag. Rather than a snappy response, the camera app is reported to be a bit on the slow side. Now, this might be no worse than many of the current crop of point and shoot cameras, but this is what we have from the reviews. The other issue is the small battery. The battery is a rather small 1650mAh unit, quite a bit smaller than the battery on the Galaxy SIII phone. The battery is rated for 350 shots. Not too impressive by DSLR standards, but 300-400 shots is pretty normal for point and shoots. However, this camera also uses GPS, has a data transmission capability that, as experience with camera phones has shown, can kill a battery pretty quickly. Also, that big touchscreen can be used for things other than just as a viewfinder for taking pictures. It can be used for editing the pictures that have just been taken, and image manipulation is a rather processor intensive task, which in turn, drains battery.
But this is not just a picture and video tool, but a fully fledged Android device. Using Google Maps to find your way to what you are shooting, checking in with Latitude /Foursquare/Facebook, and then killing some time with Angry Birds, or watching a movie or listening to some music, there are many ways this camera can drain this small battery very y quickly.
Samsung Galaxy Sharing
On the pure camera front. the Galaxy Camera is equipped with a 16mp sensor. All well and good, but don’t expect this to be replacing a DSLR any time soon. As is typical from a high megapixel, tiny sensor camera, viewing images at 100% is pretty dismal. However,checking things out on the LCD, things look good, and for smaller images and just sharing online, it seems great.
And this really is the whole point of this device. Its not a professional’s tool, its a social tool. Why choose it over a regular smartphone? Well, the zoom range and pop up flash is much, much better than any smartphone. And with that comes the opportunity to get more done than with a smartphone. It is a trade off between the money you spend and the money you can earn. There are people that do live blogging and live video streams using iPhones, and this device can aim right at that market segment. As a bonus, you don’t use up your phone battery, so you can still keep in contact with people.
But do what, exactly? These things don’t come cheap. Costing over $600, it comes in at about the same price point as a base level SLR. So the trade off for losing the image quality is the ability to post instagrammed pictures on facebook immediately? Not to mention the system is pretty much stuck in a WYSIWYG mode. There aren’t any more extensions like you would have with an SLR, no external flashes, no filter systems, nothing like that. Like I said, this is not a professional’s tool, although it can be used to provide some services in certain situations.
In my last article, I looked into the CameraMator system. On the surface, it does seem to offer similar functionality, but it means adding a $300 price tag on top of the cost of a DSLR and accessories. However, its not just about sharing pictures on FB when looking at business opportunities. With something like the Galaxy Camera, simple social media is where it stops. With a DSLR, you can add a immediate high quality printing service. Follow up prints, blown up pictures. RAW control. External lights. Professional tools simply allow you to do more, and do it faster.
So in summary, the big question is, why should you get one? Why indeed? The thing is, it depends as much on your personality as it does on your requirements. As it currently stands, I would have bought one, since it does suit my requirements, but, not at this price point. For me, its too much money for what I am getting, so this generation, I’ll give it a pass. However, it is a segment that I would keep a close eye on for future developments.
