Exposure triangle

to review what i have learned so far, i did a little photography review. i took 6 photos to cover what i have learned thus far. the first two are an example of different apertures: shallow depth of field and deep depth of field. The next show the difference between a low aperture(blurred motion) and a high aperture(frozen motion). finally, the last two photos have been taken with a low ISO and high ISO, respectively.
