Aperture

Aperture

       

In this shot we were doing some innovative filming techniques like the new wave directors would. you can see that the back ground in the shot is out of focus. This is because we were filming at around f/14 which creates a shallow depth of field.

       

This is the same shot but done again. This time we changed the aperture to f/22, which creates a bigger depth of field so the background is in focus swell as the fore ground. This made the shot look a lot better. I think it is a really nice new wave shot as well because of the innovative camera movement so its as if you are walking with me. I also break the fourth wall in this shot which has influence from the French New wave film 'Breathless' when it is highlighted at the end that the character is breaking the fourth wall.

This is the exposure triangle. To get a good shot you need to take all 3 corners into consideration. ISO is how sensitive the cameras lens is to light. Aperture is how small or big the opening of the lense is. shutter speed is how long the shutter is open for. an example of how this works is, if your camera lens is very sensitive to light then you need a higher aperture like f/22. The higher the aperture, the less light it lets in. finally you would need to make the shutter speed quicker so that it lets less light into the shot.

This is a diagram showing how to use aperture and what each one does. For most of our filming we shot on aperture f/22 as it lets less light and creates a deep depth of field.



        

As you can see in this shot, the actor is in focus but the background is out of focus. This is because the aperture would have been set at around f14 which creates a shallow depth of field. If i was to go back and do this shot again I would set the aperture to f22 to create a larger depth of field. we were using a dolly in this shot therefore next time i would also increase the shutter speed slightly. I would also make sure that the surface we were using the dolly on was smooth as the slightest bump on the ground could cause the shot to look really shaky.

New Wave

This shot was supposed to be influenced by new wave as we wanted to get a nice zoom out using the dolly to show how he is "trapped" by showing him behind the cage. Unfortunatley the shot did not work out as the surface was so un even.


Health & Safety

When filming this piece of footage we had to take some risks into consideration. One of which for this shot was that nothing was behind the dolly operator to cause them to trip up as they are walking backwards.
