Project 52: Master the Triangle

This week, Project 52 is tackling the photographic triangle – aperture, speed, and ISO.  I recall when I started shooting in Manual, it took me a long time to get even a hint of a decent exposure.  Not sure I still get it, but I’m glad we have this challenge this week so that I can refresh and remind myself how the triangle works.

Using a garden “dog”, I started with a 400 ISO, 1/1000 shutter speed, and 1.4 aperture.  With each photo, I kept the same ISO, but slowed the shutter speed a notch and tightened the aperture each time.  The exposure was pretty much the same, with the histogram somewhat in the middle.  But when my speed got to under 1/100, there was a definite unsteady blur beginning.  Too much caffeine!

ISO400, f1.4, 1/1000
ISO400, f1.4, 1/1000
ISO400, f3.5, 1/160
ISO400, f3.5, 1/160
ISO400, f9.0, 1/25
ISO400, f9.0, 1/25
ISO400, f14.0, 1/10
ISO400, f14.0, 1/10

Interesting challenge, something I need to continue to work on.  Now go over to Future Framed Photography, South Dakota to see how she handled the triangle.

  1. Great job point out the difference between photos!! I’m thinking I should have used a model like yours for this one. Hehe!!
