Thinking about Excercise 2 " Focus" and what I will use as my subjects, bottles, plants, trees, utensils etc. Also if I will use a centre focus area or move the focus points; the latter would allow the camera to rermain fixed if say on the tripod, the former would require a half shutter depression to select the focus point and then a recompose...this may mean I don't get 3 identical frames
