Before reading these tutorials, I had only ever accidentally turned on the histogram. Then, I would proceed to be irritated for weeks until I figured out how to turn the thing off again. It has a purpose?? Awesome. I know how to turn it on AND off? Even better.
I tried out the histogram function on all manual with auto focus (steps, people, steps). I adjusted the ISO to 800 and used the custom White Balance. All photos had an f/stop of 5.6
This was purposely underexposed at 1/640 (very fast shutter speed). I can just make out the cute little monkey onesie. The histogram showed color all the way to the left.
Here's a picture with much better exposure at 1/30. The focus is a bit off...I might have to take that leap to manual focus soon. The histogram showed a nice average with a peak of color right in the middle of the graph. Yay! Good exposure!
I'm amazed at how much I'm learning about my camera, and I think my photos are really improving. I'm excited to keep testing out these new techniques.
