A to Z Challenge: E is for Exposure
Welcome to today’s post for the great Blogging A to Z Challenge!
Today is E for Exposure.
Aperture, Shutter Speed, ISO. According to http://photography.tutsplus.com/tutorials/the-ultimate-beginners-introduction-to-exposure–photo-3028, the triple threat of Exposure. Well, maybe not the triple threat. The three things you need to think about with regards to exposure.
Exposure is, well, from what I can tell from my limited reading, it involves the amount of light in the shot. So, lots of things can work together to determine if a photo is underexposed (not enough light) or overexposed (too much light). Essentially anyway. I am sure those of you who really know what this stuff is all about could explain it much better!
So, three main things that affect exposure are aperture, shutter speed and ISO.
Aperture lets light in (small aperture, less light – you and I both know this by now!!)
Shutter speed – the slower the speed, the more light gets in and the blurrier things in motion will be. The higher the speed, the more you can freeze action.
ISO is sensitivity – the sensitivity of the sensor to light (and more on this for I). Low ISO means the sensor needs more light to reach “good” exposure. Use a lower ISO number for sunny days, and a higher ISO number in the dark. The literal dark. I am feeling pretty much in the metaphorical dark right now…
Anyway, here are some practice Exposure pictures for your viewing pleasure!
Too little exposure
Just right… or close to it anyway!
