You’re Doing it Wrong.
Many of us, for quite a long time, have been using the word ‘analog’ improperly. As designers, we often refer to analog technologies as being anything preceding digital technology. That’s definitely not the case. So this post is to collectively save us all from ever sounding stupid to technology nerds ever again. And don’t worry, it’s not just us, I’ve seen the same mistake made in the New York Times.
I recall a video that referred to 1950′s classrooms as ‘analog learning’ as opposed to our modern classrooms’ use of computers and the internet. I’ve heard the work of contemporary digital artists and designers compared to the ‘analog art’ of painters. The real kicker, and reason for this post, is those who position film as the ‘analog’ opposite of digital photography.
Film isn’t Analog.
Film is not analog, period. I used to shoot film on a Canon AE-1 from the ’70s. Now I have a digital SLR from Canon, and they’re obviously extremely different. But we have to be careful not to confuse ‘old’ and ‘new’, with two very specific terms like analog and digital.
The word digital, to most people, refers to a device that can capture, store, or display data in a binary fashion. Ones and zeros, on and off, digital is all about numbers. Digital shouldn’t be confused with binary, of course, as digital simply means concrete values. Any system that utilizes solid values (or digits) is digital, binary is simply the most common system. Digital cameras capture light with a sensor, that light is converted into data (numbers), so the use of the word ‘digital’ for your cell phone camera or DSLR is accurate.
Analog, however, is a very abused word. I would venture a guess that the significant amount of readers have used the word ‘analog’ to refer to film cameras. If the new, fancy robot cameras are ‘digital’ then our aging film cameras are ‘analog’, right? Not at all. Older cameras capture light with film, which is basically plastic, gelatin, and silver halide. When you take a photo (perhaps of your dog drinking a beer), photons hit this material and produce a latent (invisible) image, that can later be brought into view by bathing the film in various chemicals. You could write hundreds of blog posts on film development alone, but the point is that film photography is a chemical process.
Digital sensors and film capture light quite differently, but I’d rather hear the word ‘chemical’, ‘organic’, or ‘magic’ given to film technology before ‘analog’.
Wait, What the Fuck is Analog Then?
Analog, as its name suggests, refers to being analogous to something. If we’re referring to the adjective used in technology, the definition of analog is:
Of, relating to, or being a device in which data are represented by continuously variable, measurable, physical quantities, such as length, width, voltage, or pressure. – Wordnik
So a great example of an analog technology would be a vinyl record. The audio is stored as waves (variable data) within the grooves of the vinyl. Digital audio stores the data as numbers, as finite units of data per second. If that audio is George Clinton & Parliament Funkadelic, then funk on my brotha’. What’s important is that a vinyl record is legitimately something that deserves to be called ‘analog’. Film is not. Film captures the image physically, there is no data (waves or otherwise) to be found as there is on the record.
Plenty of older (and current) technologies are analog. Just be sure to ask yourself if that device has variable signals/data, or if that device is just really old. A television with a cathode ray tube (CRT) is an analog device; a cave painting of a man stabbing a mastodon with a spear is not. Sound waves being converted into an electrical signal is analog, a film negative is not.
Stop Saying Analog?
I know its hip to be anti-digital sometimes. But before we all drink a PBR and hop on our fixed gear bikes to the thrift store, we have to remember that just because something is old, doesn’t make it ‘analog’. 35MM cameras, oscilloscopes, and the cotton gin are all old technologies, but only one of them is an analog device.
We pride ourselves in the design industry for knowing tons of interesting things about art, advertising, and technology, but this is one adjective we should all cut back on a bit. The good news is we will always have our favorite noun: analogue! We can still say: “A picture is an analogue of a memory”, or “A cubic zirconia is an analogue of a diamond”, and “McDonalds is an analogue of real food.”
