Discussion

One factor considered in the methods was the time of day the image was taken.  In the creation of Figure 1, the image was taken around 4p.m. on a Friday and there were not many people around while the photos were being taken.  In Figure 2, the outside of Harvest in panel B had a lot more people inside and outside the store. If the image had been taken closer to lunch time on a weekday, this could explain the differences between the number of people in and around Harvest.  In panel C of Figure 2, there was less salad stocked on the salad bar. More customers in Harvest could have removed the salad so the salad bar does not look as stocked as it did in Figure 1. The number of people could have been constantly moving the tongs explaining the different orientations of the tongs in Figure 2.  Since Figure 2’s photos were taken when there were more customers, they could have forced the different camera locations as they were in the way of the photos being taken from the point of view described in the methods. Time was a factor controlled in the methods that may not have been followed in the recreation of Figure 1.
