Eggs-plaining aperture*
I'm sorry. I oughta be smacked for that.
But these are the pictures I took to show the differences in aperture. All are full frame, with the lens zoomed in (55 mm), using the built-in flash and 1/60 of a second, changing only the aperture.
This is f5.6:
This is the widest opening I could get. I focused on the spot on the egg, and you can see how the image starts to blur as you go out from the center. The edge of the egg itself isn't even in focus.
This is f8:
The edge of the egg is a little clearer, and you see some detail in the dishtowel.
This is f22:
The whole egg is in focus, the dishtowel is sharper, and (dammit) you notice the dust spots.
*Actually I haven't explained aperture at all, I just couldn't resist the pun. Digital Photography Review explains it better than I would anyway.
