Hi everyone!
As a lot of you know, I really really like lovely bokeh and DOF (depth of field). But what is 'bokeh' and 'DOF'? I hear you ask. Bokeh is a japanese term for the background blur in an image - primarily the aesthetic quality of that blur. Cheap lenses have poor bokeh while more expensive lenses have very lovely bokeh. DOF is sort of related to bokeh and background blur. If you imagine holding a ruler out in front of you and you focus on the halfway point a lens that has shallow depth of field (either a fast lens with a low 'F' number' or a telephoto lens) would have the middle number in focus but the background and foreground would be out of focus. Whereas if you increased the depth of field by increasing the F number on the lens, then more of the ruler would be in focus.
This is a recent photo of my Charanjit taken with my favourite lens, the 50mm f1.2. This 50mm has excellent bokeh and very shallow DOF, which is why it looks like it does! There is no 'photoshop blur' in this, it is all from the lens/camera.
Until next time,
