Explaining the world one sketch at a time

Understanding ISO

The sensitivity of the sensor to light. The clever folks — Willard S. Boyle and George E. Smith — who invented the CCD sensor, the basis of what enables modern digital cameras to capture light and record a photograph were awarded the Nobel prize for their troubles. And the silver halide film Kodak were famous for is equally remarkable.

Understanding shutter speed

The length of time the shutter is open, and therefore the light can reach the sensor.

Understanding aperture

A little mini-series and a little challenge for me to try and condense the interplay of the key aspects of control for photography into a few short sketches (I thought about doing this much earlier, but kept kicking it down the line). Please let me know in the following ones if it helped. Though the only way really, is to get out there, play with the settings, take some pictures and learn. One of the biggest benefits of digital photography has been the narrowing of the feedback loop between taking a photo and seeing the result. Imagine taking some long exposure night sky shots on the perfect evening after many days hiking only to find, a week or so later, that your aperture, shutter speed, ISO combo was all out of whack. But what did you do wrong? And would you remember how to correct it next time you were up there. Now you can take, test, edit, test, learn. Any time the feedback cycle narrows between doing and learning expect big changes.

The expanding circle of attention

This is my own observation — no rigorous research to reference. But, looking at our 2 year old as he’s transitioned from a baby, I’ve been led to think about our times on, say, public transport. A baby will largely only focus on what’s right in front of their faces or directly impinging on their senses. As they grow, the vicinity becomes their circle. So if you’re on the tube, anything within sight in the carriage is fair game for them to fiddle with or want to investigate. But adults are capable of just sitting there - thinking, about things far away, in the future or in the past. It strikes me that small children just can’t do that — life is what’s around them or nothing. Hence endless fidgeting and investigation. Brilliant.

Often missed phobias

Atelophobia: Fear of imperfection. Decidophobia: Fear of making decisions. Soteriophobia: Fear of dependence on others. Probably afflict more people than know about these.

The improv attitude

The improv attitude

Fail cheerfully. Be obvious. It’s not about you. Dan Klein is my improv guru having had the fortune to learn from him a couple of times. Thanks Dan. And, as usual, improv tips tend to extend as good practice beyond improv.
