Its a 52 week challenge this weeks single image subject is to show "Depth of field" hope the definition is adequate

loosend the range a bit

A 10 second exposure, Aperture f/32.0 Focal Length 100 mm with virtually no field definition.

and a an outside Image showing near focus bluring the reart of the image a little

great...i have done a bit of this in a local gardens where there are little sticks in the ground with numbers to show where certain species are planted...in the early spring
and its a good way to show those who dont quite understand just what the lens is doing at different apertures
its sometimes a waste to stop a lens down too much and loose valuable speed..
cheers

I think it would be a good idea if you were to include your Apertures for the shots and focal length including your distance from the subject.

Although aperture primarily controls DoF (and level of light in), Focal length and subject distance are the other two main factors affecting DoF.

e.g. F2.8 at 10mm looking at a landscape with no foreground subject is pretty much going to put the vast majority of the scene in apparant focus (until you zoom right in where it might look soft) as opposed to F2.8 at 100mm with a foreground subject 6ft away (for example) in which case the background would be much more OOF.

Just as basic examples anyway.
