237	237	Circles of Confusion	Long before I worked on the web, I specialised in training photographers how to use large format, 5×4″ and 10×8″ view cameras – film cameras with swing and tilt movements, bellows and upside down, back to front images viewed on dim, ground glass screens. It’s been fifteen years since I clicked a shutter on a view camera, but some things have stayed with me from those years. In photography, even the best lenses don’t focus light onto a point (infinitely small in size) but onto ‘spots’ or circles in the ‘film/image plane’. These circles of light have dimensions, despite being microscopically small. They’re known as ‘circles of confusion’. As circles of light become larger, the more unsharp parts of a photograph appear. On the flip side, when circles are smaller, an image looks sharper and more in focus. This is the basis for photographic depth of field and with that comes the knowledge that no photograph can be perfectly focused, never truly sharp. Instead, photographs can only be ‘acceptably unsharp’. Acceptable unsharpness is now a concept that’s relevant to the work we make for the web, because often – unless we compromise – websites cannot look or be experienced exactly the same across browsers, devices or platforms. Accepting that fact, and learning to look upon these natural differences as creative opportunities instead of imperfections, can be tough. Deciding which aspects of a design must remain consistent and, therefore, possibly require more time, effort or compromises can be tougher. Circles of confusion can help us, our bosses and our customers make better, more informed decisions. Acceptable unsharpness Many clients still demand that every aspect of a design should be ‘sharp’ – that every user must see rounded boxes, gradients and shadows – without regard for the implications. I believe that this stems largely from the fact that they have previously been shown designs – and asked for sign-off – using static images. It’s also true that in the past, organisations have invested heavily in style gu…	2010	Andy Clarke	andyclarke	2010-12-23T00:00:00+00:00	https://24ways.org/2010/circles-of-confusion/	process
