Photography Abbreviations & Slang. The Jargon Buster
©Bill Bagshaw
Photography abbreviations invented by manufacturers & techno geeks get ever more confusing.
Un-neccessary techno babble is most confusing, and is often used extensively by photographers with very little knowledge about the creative side of photography.
An example is ATGNI – All The Gear No Idea – refers to someone who mistakenly thinks buying expensive gear is all you need do to be an ace photographer.
Most recent techno gibberish spotlight.
You thought there was just DSLR (digital single lens reflex) cameras & compacts ? Wrong. There has always been different types of cameras but digital is now spawning multiple abbreviations.
Compact Camera Systems (CSC) now have pseudonyms /variants/acronyms including MILC, MSC, EVIL, DSLM, micro four thirds.
Have you met a smudger or seen a zoom creep ?
Is your camera EVIL ?
Do you know a chimper, an Uncle Bob or a sprayer?
Here’s a handy techno babble list:-
Don’t get bogged down by all this techie stuff, it will drive you mad.
Concentrate on the creative side of your photography instead.
The simple fact is that spouting all this guff won’t help you to take great photos.
If you meet someone who spouts this nonsense it’s highly likely they know nothing about what photography really is.
They could be a smudger dweeb who sprays and prays, – or maybe a numpty camera reviewer.
