The Cambridge Student featured a recent photo as photo of the week, it’s of King’s Frontage reflected in the window of Nomads:
Macro Lenses are expensive, prohibitively so for me. I bought an Opteka Macro Lens from Amazon, which is a tenth of the price, and just screws onto the end of the standard kit lens, with excellent results. The depth of field is tiny, but with a bit of tweaking you can get excellent results. An album of my first try with it is on my Picasa.
I made a homemade bokeh filter for my camera. As it’s just using the kit lens, the size of the design is very small, and this limits you to taking photos at full zoom, and you can’t get all the nice effects you get with a proper filter and a lens with a really large aperture, but it’s still pretty good fun!
