This video is evidence of what pull focus is, where the point of focus starts on one object or person and then changes focus onto a different object or person. In this video the original focus point is the camera in the foreground, and then transitions focus to the person standing in the background.
This video is an example of the a dutch tilt indoors with low light levels. The ISO is set at 1600 with the aperture being higher to allow more of the light to be allowed to hit the sensor. The troubles I had with this shoot was the floor was not level and the camera would unintentionally be canted to the left, to try and counter this I raised the legs slightly to level out the tripod more, but it wasn't as successful as hopes.
Video of a street with high key natural lighting, with ISO on the camera set to 200 and the aperture is a lot lower to be able to balance the light entering the camera . The shot is using a low camera angle, looking up to
When it came to taking the night time examples I faced multiple issues, one being that the camera I had selected to take the images would not allow me to change the ISO when using the filming mode, and so the images had to be still photos. However they still show the differences of different ISO settings and the effect they have on image quality. This top image for example is pointing down a well lit street with multiple light sources. With the ISO set to 1600 and the aperture to the lowest setting possible on the camera I used, and with 1/50 shutter speed the image looks almost pitch black with the street being very lightly illuminated. Compare this however to the bottom image which was taken with and ISO of 200 with the other setting remaining the same, we can see that only the actual light sources are visible such as the street lights, indoor lights from windows or the illuminated signs from shops, the road is not visible or any buildings.
