This year my wife and I decided that it was just easier for each of us to buy our own anniversary presents and pretend it was from the other person (much easier that way). Des got herself some fitness equipment and I bought a... lens (I know...big shock).
for those that are interested it is a 50mm f 1.8 lens. at 1.8 it has a really shallow depth of field so you can isolate parts of your subject really well. In addition, it is 4x faster then the "kit" type lenses that come with cameras, meaning it lets more light into the camera. it's not the most expensive lens (actually it's one of the cheapest lens canon sells) but I wasn't prepared to spend 4x the price on the next best one (f 1.4) or 12x on the top of the line one (f 1.2).
Here is a sample shot I took to demonstrate to my wife why I bought it:
And again for those interested. Here is how I shot the above image:
I used an old cardboard box, 2 sheets of white paper, 2 sheets of glossy craft paper and some flashes. I cut holes in the sides for the light to shoot through and covered them with the white paper. Then I cut a hole on the top and covered it with one of the glossy pieces of paper in case I need to have light come from above in the future. Than I taped the last glossy page to the back wall and let it curve toward the camera to create a seamless background.
