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.
