S is for....

Sensitivity!!

I had fun with this one. =)  I was able to dedicate more time to the exercise, so I did it over and over again with different objects.  My favorite ended up being a vintage brooch that I found in my grandma's old jewelry box a few months ago.

I had to start with ISO 1600 and go from there because my camera doesn't have ISO 3200.

ISO 1600, shutter speed 1/80

ISO 800, shutter speed 1/50

ISO 400, shutter speed 1/25

ISO 200, shutter speed 1/10

ISO 100, shutter speed 1/6

Looking at each picture zoomed in, I initially had a hard time distinguishing differences between them.  I knew what I was looking for (based on what we learned at the first workshop), but I had a hard time picking it out.  It wasn't until after zooming in, picking a specific edge and looking at that same spot on each photo, that I was able to see the effects of different ISO. The lower ISO I used, the more precise the zoomed image was.  It wasn't as grainy, and more detail could be seen (ie: each individual thread making up the ribbon).  I think it would have been a lot easier if I could have done a side by side comparison of each photo, but after a lot of flipping back and forth the differences caught my eye.  Now I can't help but notice!
