Overdue Homework

I'm finally posting some homework to be graded. It's long overdue but I figured it was time I should do it and actually get some practice in. The first task was learning about depth of field. I had a hard time with this one because my camera really limits what I can set my aperture at, even when I am in a manual mode. I gave it a whirl but I really see very little differences in these pictures. It was on this task though, that I finally learned that I can focus manually with my camera. Again, it is very limited but at least this camera has the ability and I was very happy to have discovered it.

TASK 1
7 objects in a row, attempting different f-stops. AV Priority, using a tripod & 2-sec delay to help avoid that stupid camera shake icon ('twas no use). I didn't control the shutter speed and I could only move the f-stop in increments that the camera set, not one at a time. My manual focus was set on the blue block closest to me.

f 3.5, 1/20
f 5.0, 1/10
f 6.3, 1/6
f 8.0, 1/4

I see very little difference.

TASK 2
A long edge with 3 different focal points. I think this turned out like it should have. I also made an attempt to keep the entire edge in focus and have it drop off at the end into pure fuzziness but I couldn't figure that out. I blame the camera. Hahaha.




TASK 3
This did not turn out AT ALL!
Dark room (with very little light), shiny object, tripod, 2-sec delay, flash disabled. Adjusting the aperture till object is in focus at an estimated distance. Once again, I had my camera in AV priority. This was the best pic at f3.5.

Yikes.

  1. I don't know your camera well enough, but I think the task was to set the object at an estimated distance and adjust the focus to that distance (not the aperture - that wouldn't make much difference except for the depth of the field of focus); the question is, do you have focussing distances on the lens of that camera? Even some of the dSLRs didn't have that printed on the lenses, so I just want to confirm.

  2. Nice focussing!

    I say try the DOF assignment with just 3 objects, and set them maybe 6-8 inches apart - you'll definitely be able to see the DOF 'expand' better. (The original exercise wasn't very well written - I'm learning stuff in this workshop too, see...)
