What the F?

It occurred to me this evening that I don’t have a lot of people, if any, that I can really discuss photography with. Accounting, check. Marketing, check. Business, check. Mom-Life, check.

I was having a conversation earlier this evening about potentially buying myself a new lens. The lens I have is great, but I REALLY want a lens with more bokeh and a lower f stop. You would think that I was speaking in gibberish, and I guess in a lot of ways I was. Sometimes it’s hard for me to remember that not everyone knows what I’m talking about anymore than I would understand any basic algebra equation.

So…for anyone who doesn’t know that will ever see these two words mentioned either here or on any other photography page:


bokeh –  the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as “the way the lens renders out-of-focus points of light”. Differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting.

aperture –  in a mechanical sense, refers to the size of the opening at the back of the lens, which controls how much light is being passed onto the camera’s sensor.

Aperture, often called F-stop, is important to the exposure of your photograph, but it also affects how much of your image is in focus, or the ‘depth of field’. This is an important stylistic choice, and impacts the look and feel of your image.
