Hey there everyone! Are you in full swing of Thanksgiving prep yet? Or are you like me and campaign for the pickle platter assignment at the big family feast?
Ok, down to business! In my last post I talked about exposure and how aperture + shudder speed + ISO work together to create it. Out of the three, aperture is the most complicated - but don't let that scare you! Remember how I like to keep things simple? Well, here goes!
When your aperture has a small number (think 2.8 for example), the "hole" is more open than an aperture of 8. The example below isn't perfectly to scale, but you get the idea - right?
Yes the whole number concept seems backwards with the wider opening having a smaller number, but you'll get used to it! Not only does this affect how much light gets in, but it also controls the depth of field. Think about the pupils of your eye and how they dilate to let in more light in a dark room, or retract when you step out into the sun. Well, aperture acts much like that except that it's not near as sophisticated as the human eye (dang!), and to work at its best, WE have to be the one deciding how much light to let in.
