Comparing Scene Modes and Aperture Modes

Aperture f16

Scene Modes - Portrait

                     These pictures are very different. In the scene mode, the aperture was at f 2.7 and the ISO was 75. In the Aperture f16, the aperture was 16 and the ISO was 400. The Scene mode was taken inside, while the Aperture was taken outside. The difference in aperture reflects the clarity in the foreground. Because the location of the pictures was different, the ISO had to be greater or smaller accordingly. Since the Scene mode was inside, the ISO was 75, while the Aperture f16 photo was at an ISO of 400. Consequently, the Scene mode was darker while the Aperture f16 photo was lighter. Also, the Exposure compensation was +1 in the Aperture f16 photo when it was 0 in the Scene mode photo, making the Aperture f16 photo brighter. Furthermore, the shutter for the Aperture f16 photo was 1/100, while the shutter for the scene mode was 1 (I took the Scene Mode photo with my Cannon at home, which did not have the shutter in a fraction, only a decimal. That is why it is mentioned as 1 for the shutter). The shutter for aperture f6 photo was slower, letting more light in, therefore it was brighter than the scene mode photo. In conclusion, because of the shutter, aperture, ISO and exposure compensation all make the aperture f16 photo lighter and the scene mode photo darker.
