I should have grabbed my tripod to take these, but truth be told, I was feeding a toddler at the same time and used the flower as my subject because it was on the kitchen table. I think I have a pretty good grasp on aperture; its keeping the lighting correct as you increase the f stop that gets me. As you can see, the bottom pictures get more yellow because of the aperture closing and letting in less light. I'll figure it out eventually. Hopefully.
Next week's lesson is ISO and shutter speed. Stay tuned!
