Day 333 - The blurred brick wall
There are a lot of decisions to be made when taking a photograph like this. You have to decided how to frame the shot, how close to get to the objects in the foreground and how much space to leave around them (on the sides and top and bottom). You have to choose the angle from which you take the photo (again, both from side to side and up and down) which will have an impact on what forms the background to the shot.
Once you've made those decisions, you have to choose whether you wish to have all elements in sharp focus (by prioritising a narrow aperture setting on the camera) or different levels of focus at different levels of the shot (by opening the aperture up and then compensating by speeding up the shutter). I had the aperture setting at its smallest (f8) with the shutter at 1/60th for the first picture I took of these lamps and the shot was boring: everything was in focus.
So then changed the aperture to f3.4, increased the shutter speed to 1/125th of a second and suddenly you've got this much more interesting image, where the finely focused lamps stand out against the interestingly textured but blurred brick wall.
