There’s a great book called The Psychology of Everyday Things that was my introduction into why I found some things strangely difficult to operate. I remember a pal’s Alfa Romeo car that had a bank of identical, black, flush, push-switches to operate things like the heating and air flow. Not only was it impossible for the driver to use them without taking their attention away from the road, I can vouch for struggling to work out which one to use when I was the passenger. Was it in the Hitchhiker’s Guide that the spaceship had a black control panel of black buttons that lit-up black when pushed? Alfa got there first (or I suppose they would be called Omega).
Good design works because it leads you. Bad design breaks the flow or works contrary to expectations. Have you ever pulled on a door that had a handle, only to find it opened with a push? Poor design. There is a wonderful blog series called The Weekly Design Roast that I recommend for examples to make you weep.
In camera terms, I find that digital cameras usually have poor operating design. It’s probably because the camera is capable of so much and there is a strong commercial pressure to add features. You know how it goes – “ooh look, this one can do focus-stacking or that one can do HDR, or do I spend a bit more and buy the one that can do both?” And then we have no idea how to use the special function because we didn’t memorise the manual. A guy recently mapped-out the menu system of a Sony camera. That’s what happens when a very complex device is squeezed into a small package. Or when features are added to the point that they exceed the interface.
Canon did a thing with their digital compacts. It made sense in production to use the same processor in different models, so they disabled some of the features in the cheaper ones. And then we found out how to turn them back on again. The common component build is very sensible in manufacturing, and what an Easter Egg of delight for the fanboys who found out how to hack them. It also made sense to remove features from the simpler models in the range, and this was an easy way to control the feature set with a limited range of electronics.
Perhaps a better example is a humble clip. This is a thing used by sailors and divers to attach one thing to another. Exhibit A is a stainless steel item comprising five components and requiring machining, drilling and bending to assemble. Exhibit B is the alternative that does the same job with two components, only one of which needs bending. Good design makes manufacturing easier and creates less waste. The simpler clip also has no sharp edges that could damage a rope or fingers.
The opposite of this would be a microwave oven. What you want is to control the power, control the time and be able to stop and start it. What you get is usually so confusing that you need the manual. A manual, for a machine with two variables?
Or if you want an example of a very simple machine with poor design, take a look at one of those cute-looking anthropomorphic vacuum cleaners. They get stuck on every doorframe or piece of furniture. If you pull them, they stay stuck but the side catches open and the top falls off.
So what has this to do with photography? Camera design can be a collision of feature bloat and bad ergonomics.
There are cameras that it is possible to hold wrong – see the Contax/ Kiev 4.
There are some where you have to wind on before changing the shutter speed or you break them – see old Russian rangefinders.
Then there are cameras that make you wonder what the designers were smoking – how about the Konica AiBorg?
Or there’s my experience with The Ergonomic Disaster.
I’ve had a long-running fight with more than one digital compact to try and get the built-in flash to balance with an external one. And the clever dedicated flash for my dSLR needs me to carry the manual to have any hope of changing the settings. In fact, the flash is a microwave: it has strange controls with weird symbols and no obvious way to change the main settings. I admit to writing on my dSLR with a white marker to differentiate the metering control from the focusing control.
If I look at my Canon G9, an up-market compact, it has nine buttons, four rotating dials, two rocker switches and a shutter release. Some of the buttons bring up menus on the screen to choose more options. Some of the buttons are used a lot – flash on/off, macro on/off and zoom. Some I’ve never used, like print. There’s one button that I hadn’t noticed until I counted them and I’m not sure what it does.
I suppose the opposite extreme is my little Sony compact that has almost no physical controls and relies completely on menus and a touch screen.
I recognise that digital cameras are so clever, with so many options, that multiple controls or menus are needed. But perhaps what I want is the sort of design that was built into the BlackBerry phones. On the surface, they just worked. But there were features and shortcuts built in that you could use to do things easier or quicker. Using them gave a feeling of delight, but not using them didn’t get in the way of its core function.
What’s a well-designed camera then? I don’t know, because I don’t think I’ve ever seen or used one. You may think a camera is a simple design, so try this on a beginner:
This is a film camera. Wind it on after every shot with this lever. Yes, or it won’t take a picture. You will know the film is finished when it won’t wind on, but don’t push the lever too hard. Then press the little unlabeled button on the bottom of the camera. Pull up this little folding handle here and wind it round. There may be an arrow to tell you which way to turn it. Or not. You will know when the film is rewound when the handle turns easily. Or jams. Pull the whole winding thing up to open the camera. Yes, it does look like you are breaking the camera. Pull it some more. The back of the camera will then pop open. Pick up the film from the floor. And the camera. Try to wind the end of the film completely back into the cassette so you don’t shoot it again. No, twist it the other way. See that bit inside the camera that you poked your finger through? That was the shutter. Yes, it was important.
Why do you think point and shoots and compacts sold so well?
I’m not a klutz and I am comfortable with technology, but I can tell good design from bad. And there ain’t half some bad design out there. What’s your experience?
