You have 7 days to take a photo with a shallow depth of field, usually using the widest aperture you can, though you might find getting close to your subject and/or using a zoom lens will also give this shallow DoF.
Let’s brush up on some technical fundamentals, shall we? What is a Shallow Depth of Field? Well, you know those “professional” photos where the subject is in sharp focus and the background is all beautifully blurred? This is a photo with a shallow depth of field – the plane of focus is very thin, and everything behind it (and in front of it) is fuzzy, or soft. This fuzziness is often referred to as “bokeh”, and the type of bokeh will change with lenses, aperture settings, and a few other things
Here are a couple of photos along with the featured image that I considered for this challenge… which I finished at the last few hours.
