Slow Shutter Cam review
People say you can’t do much with mobile cameras when you take the photo. It’s all in the processing, they say. Well, true. With most mobile cameras, you have no control over the three points of the traditional exposure triangle: ISO, aperture and shutter speed. But there are a few apps that do allow you to take control over one of those variables: shutter speed. Slowing down your shutter speed is something big-camera photographers so all the time - it’s one of their main creative tools. This article looks at one of the apps that give you that same tool with your mobile camera: Slow Shutter Cam by Cogitap Software. Retailing at a ridiculous $0.99, this app gives you huge creative photo-taking potential.
So what does it do? As the name suggests, it allows you to slow down your shutter speed. You decide how long you expose your sensor to the scene in front of the lens. The app makes adjustments to ensure you don’t over-expose your photo but if you leave the shutter open for a long period (say 10 seconds) and anything moves in your frame (or if you move your camera) you will get some blur. But it is precisely this blur that makes it such an exciting creative tool.
One of the common reasons for lengthening the time that your sensor is exposed to light is when you you’re working in low-lighting situations. In this case, any movement may in fact be unwanted rather than creative distortion.
Example of a low-lighting scene shot with Slow Shutter Cam
If you use Slow Shutter Cam as a practical remedy to a low-lighting problem (rather than as a creative tool), you will need to keep your camera still (eg by using a tripod). If something in your scene moves while you are taking the photo, it will show up in your final exposure as a blur. But that’s part of its creative attraction. Holding your camera still, while something in your scene moves is the first of the three main ways people use Slow Shutter Cam creatively. It’s a technique that big-camera photographers have used for many years. It allows us to create the classic waterfall image, where the water is smooth and fluffy, and the image where lights on passing traffic create a trail (see below for a variation on this).
This technique can be used in more creative ways too if applied to things other than traffic and waterfalls (eg people).
The second, more creative, technique is to move the camera on purpose while taking the photo. The combination of this technique and the use of the app’s light-trail mode has produced a very characteristic “look” in more experimental mobile photography. When people are included in an image of this type, they take on a Modigliani-style stick-insect aspect and it’s a look that has been widely used.

It’s a technique best used when an image contains very well delineated blocks of colour. One of the leading proponents of the technique is American artist, Cindy Patrick, whose beach scenes are some of its best examples.
The third technique is to move the camera in parallel with a moving subject, a technique known as panning. If you are able to keep your frame more or less fixed on your subject, the long exposure will give you an interesting mixture of well-defined features and blur.
Examples of panning with Slow Shutter Cam
While primarily an app for taking photos, it does have an amazing post-production feature that you will not find on a DSLR: freeze-frame. This feature effectively divides your long exposure into multiple frames, the first and the last frames being very sharp and the ones in between having varying levels of blur. You can save any of these frames and then, using an app like Blender, blend them together to your heart’s creative delight.
So when people say mobile is all about the processing, remember Slow Shutter Cam. Although the images it allows the user to make may often have a painterly or experimental look, it in fact takes us back to the roots of photography by allowing us, especially if we use the techniques mentioned here, to feel we are really drawing with light.

Point and don’t shoot with iPhone 5S camera
I know the iPhone camera isn’t technically a point-and-shoot. But you’re supposed to be able to just pick it up and shoot, right? So it’s a press-slide-and-shoot. Except with the 5s, there’s a stage missing in that description. Unless you tap on the screen before you shoot, your photo will most likely be out of focus. Check out the details from two photos below, taken seconds apart. They have the same lighting conditions (very bright so no danger of camera shake interference) and were taken from exactly the same distance using the native iPhone camera, but the one on the left was taken without tapping and the right one was taken after a tap. You can see there’s a major difference in resolution, which is clear to the naked eye in the photos at full size.
The 4s didn’t seem to take out-of-focus shots if you didn’t tap. I know about tapping to focus and expose on particular points, of course, but the iPhone camera was supposed to auto-focus if you didn’t tap, right? Let’s hope Apple sorts this out for the 6. Or maybe I should use one of those camera replacement apps that I’ve been so dismissive of lately!
What happened to all the mobile photo apps?
The other day I was complaining that I didn’t think there were any new mobile photo apps coming out any more. Like a middle-aged Dad complaining that pop music isn’t what it used to be, I realise this could be because I’m just not paying close enough attention any more. But I tweeted it and no-one really came back with many suggestions of what I had been missing. “Mobile has caught up with desktop!” I boldly pronounced. Well, some news about Adobe’s Lightroom this week suggested to me that mobile may actually have overtaken desktop rather than just caught it up.
First, Adobe announced the release of a “mobile” version of Lightroom. They say mobile, but really it’s just for iPad at the moment. So mobile in the sense that you can carry it around, not in the sense that it’s for mobile phones (I think they call them cell phones in the US). For me, the main advantage with that is that I can sync multiple edits to various photos at once - something I do a lot with desktop Lightroom. Second, I found out that the new Lightroom 5 has two new features that have long been very popular with mobile photographers. They are 1) spot healing for custom shapes and 2) the parallelisation (is that a word?) of lines. In the case of 1), you have always been able to spot heal with Lightroom, but only circular patches. For me, this was always a problem: often I’ve wanted to remove a cable or a mic stand from a picture of a singer on stage. On the mobile, with an app like Handy Photo, this was already very easy. Just mask, tap and boom - unwanted thing gone. For 2), this was something I’d always loved doing with Genius Scan+ and then later with Perspective Correct. The classic example given is to straighten the sides of a building, but I’d used these apps more creatively sometimes, but also just to tidy up a picture when I couldn’t quite get the right angle to take the picture from.
For me, then, and probably for a lot of other mobile photographers, I’m transferring skills I learnt on the mobile to my big camera photography.
Spending less time, effort and money on the street
I went to a brilliant exhibition of street photography recently in London called Only in England, featuring the photos of Tony Ray Jones and Martin Parr. All the photos were taken in the 60s and 70s and so were all taken on film. I was with a group of photographers, Click London, who mostly use mobile cameras. The most fascinating part of the exhibition for us mobile photographers was a wall covered with printed negatives, showing the ones that had made the cut and the ones that had been rejected. It reminded us of our own mobile shooting: they shot on film but they still got lots of duds too! On our digital mobile cameras (especially with our new burst functions) we thought we took lots of frames before we got a good one. Looking at Tony Ray’s contact sheets, he probably took as many photos as we do now. He just had to spend a lot more time, effort and money doing it.
Many of our group are avid street photographers and Tony Ray-Jones and then later Martin Parr are two of the England’s greatest street photographers. Each day as we look through our Instagram and Flickr feeds it is easy to see their influence. People are striving to capture that moment on a street where everything comes together in perfect balance, where the look on a face coincides with a gesture elsewhere in the frame. They very rarely equal the standards set by these two photographers as shown in this exhibition. To get a good street shot requires a combination of various factors: 1) a sense for when something is about to happen; 2) an eye for the right composition; 3) finding interesting subjects; 4) lots of time: the longer you hang around, the more likely it is something will happen; 5) lots of frames: we can see in this exhibition that Tony Ray-Jones used up a lot of film.
We think we get a lot better at photography thanks to our new technologies. But in fact, comparing our photos to those of Tony Ray-Jones at this exhibition, we see that it’s only in one out of five factors that we are helped.
On the street
This is a follow-up to last week’s bloggy about a big-camera photographer who said he used his mobile phone camera as a “notebook”. I wonder if he ever went back to that train platform with his big camera to properly re-take that lovely Magritte-esque image that he captured with his humble mobile phone camera? It looks at another example of big camera photographers’ attitudes towards mobile.
I follow the Instagram feed of a professional photographer who works for one of the world’s leading agencies. I really love his photography but I recently saw one of his mobile photos and I thought: I wonder if he’d have submitted that image to his agency if he’d taken it on his big camera. The image was of an ice rink, taken from probably 20 or so rows back in a stadium. The ice-rink was completely blown out in the image. Not surprising: the white ice was brightly illuminated and the stadium stands were almost in darkness. I’ve been using an HDR app for many years on my iphone (Pro HDR) and I recently found that the new Canon 5D mk iii had added an in-camera HDR option (I wrote about all this for FLTR recently). I’ve always found that Pro HDR is great for just this sort of high-contrast situation. I wondered if my Instagram friend had heard of Pro HDR. So, as politely as I could, I asked him. “That’s a striking image,” I said, “but I was wondering if you knew about Pro HDR? You might have reduced the contrast between the ice rink and the stadium with it?”. A few days later I got a curt reply saying that was exactly how he’d wanted the image to look thanks. Really?
This is something I’ve come across before. Big-camera photographers sometimes almost deliberately create crap photos with their mobile cameras, as if to say, I’m off duty now, this doesn’t really count, I’m not even going to try with this rubbish mobile device.
HDR can help
When is a photo not a photo? When it’s a note
I was admiring some lovely photos by an excellent big-camera photographer the other day and I noticed that one had been taken on a mobile camera. It was a picture of some commuters standing on a misty train station platform. In the notes to the photo, the photographer said that “often I use my phone camera as a notebook”. Which I thought was an odd comment. It was a beautiful image already. It was an image that had been taken on the spur of the moment, as the scene (reminiscent of a Magritte painting, he noted), unexpectedly unfolded before his eyes. So an image, like many, that was only captured because the photographer had his mobile phone camera with him at the time. The best camera, etc. as the cliche goes.
But in what sense is this picture just a note? Is he going to come back later with his big camera and recreate the scene? The scene was a fleeting moment, gone in probably just a couple of minutes. The mist would have lifted by the time he’d returned and the commuters would have got on their train into town. It is unlikely to ever be recreated in that exact composition and light ever again. And it was a photo that already stood up on its own as a very strong image. Somehow the assumption is that the photo wasn’t a proper photo (it was merely a “note”) because it hadn’t been planned and wasn’t taken on a big camera.
Hold that shadow just there while I get my big camera
iPhoneography teaching career takes unusual turn
My iphoneography teaching career took a rather unexpected turn a couple of weeks ago. I received an email from a man who found me on the internet and asked if I could give his wife a private iphoneography class as a birthday gift. I imagined myself jumping out an iphone-shaped cake, declaring “Surprise!”. My bearded middle-aged and slightly chubby face would muster the biggest smile it could, but even in my imagined fantasy the birthday girl still only stood there, slightly bemused. “A what? For my birthday? “.
"Well," I replied to the email, "that’s a very … thoughtful gift", not wanting to turn down good business. "Where would you like to do the class? I could come round your house, or meet somewhere in central London?".
“Well, actually,” came the reply. “We’re in Zurich. Could you fly over in the morning, do the class in the afternoon, and then fly back in the afternoon?”. And before the end of the day, I had received an email from SwissAir confirming my flight. When the birthday came, I flew off to Zurich, and, with a red hanky in my top pocket, met up with the lucky lady on platform 9 of the main train station, accompanied by her husband. We had a lovely time wandering around old Zurich, taking photos and then dipping into coffee shops to do some photo apping.
I hadn’t been advertising this service but it follows another private lesson after, again, I’d been found on the internet and persuaded me to do some private tuition. In this case, the classes were closer to home, North London, and took the form of me going around to the homes of four charming ladies, all young mothers with children at school during the day, for four weekly sessions. The story of that one is told by, Emma, who found me on the internet, on her excellent blog LifeofYablon.
Why am I telling you all this? Well, the first is that it gives me an excuse to mentally jump out of an iPhone-shaped cake and shout “Surprise!”. The other is that I’d quite like to do some more. So if you know anyone who has a birthday coming up, or has some time to spare during the day, you can find me on the internet.
OK, first thing. That’s not an iPhone camera.
