in the first sequence of pictures we gathered three random objects and lined them up in a row. for the first picture we put the aperture on the lowest setting (4.5) which made everything out of focus except for the main subject (the hand sanitizer). In the second photograph i put the aperture on a middle setting which lengthened the depth of field and made the background more in focus. in the last Photo i turned the aperture on the highest setting so that everything in the picture was in focus. The first picture is my favorite of all three.
