I belong to a Flickr group that posts a wide range of images on its section. Every so often a type of photographic virus invades some of its members turning the creative part of their brain to copy what's been posted. The latest virus to attack is 'surreptitious passenger recordus'. Others have been Milky Water syndrome and the deadly HDR virus.
It was first noticed on the District Line of the London Underground and when small digital cameras with articulated viewing screens became available. The ones that allow you to cradle it in your lap and whilst casually looking the other way after framing your subject press the shutter whilst pretending to clear your throat.
The results are usually three or more people sitting on a seat side by side, one looking bored with one usually asleep another reading a newspaper and another busily engaged with a phone or tablet. All well and good I suppose, but it's when three or more people post similar images following the first, you know that the virus has spread and creativity has been compromised.
The fact that the photographer can be seen clearly reflected in the carriage window opposite may be cause for concern. This could be a desire to be seen as a photographer or just that the urge to copy others has blinded him/her to what actually is in the viewfinder.
Don't worry if you think you are infected, it's a common complaint that is endemic in the photographic world and affects all of us that picks up a camera, you just have to learn to live with it!
Keep calm and carry on!
