In photography there is a concept called subject isolation, which simply means make sure what you want people to see in your photo stand out. This is commonly done by using a narrow depth of field to cause an intentional blur of everything that is not the subject. This effect is often called bokeh, and its popularity is the reason that so many wide aperture lenses are being made to day.
I recently got the ‘thrifty 50’ 50mm 1.8 prime from Sony. With the aperture open to 1.8 this lens should have a very narrow focal plane and lots of background blurring. Throwing on a tube extender for some ‘macro’ shots narrows the depth of field even further. I went for a walk to the local rose garden, self assigned to practice some subject isolation and try out the new lens.

Jonah, these are great! Are you shooting in RAW to be able to print (big?). I was at Lightwork today printing two 16 x 24 prints for a show at SUNY Oswego. I’m going to print more in the coming months. When you ever visit Syracuse again you might want to spend time there.
Yes, these are all RAW and could be printed large format. I haven’t yet gotten any of them printed, but its something I’m considering.
