Using a 50mm prime lens I captured this selection of snaps in the park to mess around with the aperature, I set the ISO at 100 and set my aperature starting at F/ 2.5 and SS 1/125. and kept closing down my aperature while simultaneously slowing my shutter. I did this twice just to kind of have fun with the second attempt with all the random items I could find.
Aperature can be used strategically to hilight your subject while fading your backround. It can be used to tell a story, follow a certain narrative or for practial focus reasons. The shallow depth of field created when your aperature is wide open lets you get up and personal with a close up subject especially with a macro lens, or similalry can allow you to dissociate a further away subject from the backround enviroment. Shallow depth of field can create great detail in your foreground while a more stopped down aperature is uselful for wider less close shots such as lanscape photogrpahy where you want detail in the full frame.
Week two entry.
The shots this week were a mixture of shallow depth of field and messing with the aperature. Here are some of the shots I got from that week
ISO 200, F/ 4.5, SS 1/250th
F/ 5.0, 1/20, ISO 200 F/ 16 0.5sec, ISO 200.
F/ 5.6, 60mm, 1/15th, ISO 200.
F/ 3.5. ISO 400, 1/2500th.
F/ 8, ISO 400, 1/50th.
