f/1.4 | 1/800 | iso 100 | Canon 50mm f/1.4 USM
Thursday already…where on earth is this week going? I couldn’t decide which image to use today so you are getting both! 😛 The current theme started with yesterdays image, it’s going to be images taken at f/1.4.
What does f/1.4 mean? Basically, each lens has a diaphragm consisting of blades which open and close allowing more or less light to hit the camera sensor. The aperture value (the “f-stop”…in the photo above it’s f/1.4) is the diameter of the “opening” the blades makes. A value of f/1.4 would create a large opening allowing in tons of light and typically creating more areas which are out of focus where as a value of f/22 would create a tiny opening which of course, would allow less light to pass through and would create more of the image to be in-focus. Does this mean to shoot at f/22 to always get clear images…nope, there are many other factors which are involved and believe it or not, it’s not always best to shoot in the f/22 range as even through more of the image might be “clear”, it won’t always be as sharp. I know, I know, confusing…remember, this is a very very basic description! 😛

Okay, I think I have decided I like the first image the best…
