So now that we've pitched our short film ideas the next step is to get to grips with the camera's we will be using, last year we used big Sony HD Cameras THIS year we've splashed out and now have Cannon DSLR 600D Camera's these camera's are more complex than last year, so it requires extra research. The advantage of these camera's is it allows us to produce a cinematic film quite like the blockbuster films but without the blockbuster budget.
These camera's are a lot more hands on and allows you to do a lot more things manually which gives you the power to influence your shot. Things we had to learn about these camera's were things like:
- The Aperture, ISO and Shutter speed, all of which will change the look of your picture or film shot.
- The lenses we could use while filming
- Auto focus and manual focusing
These were a few things we had to research. luckily we had video tutorials to explain the complexity of the use of these cameras.
Lens types
There are a few lens types; a kit lense, a zoom lense, a prime lense and an extreme wide angle lense.
All these lenses give a different shot and we must know what all of them do, fortunately out research was easy on this as there was a readily available video informing of their uses.
The video is posted below watch it for information on the DSLR lenses we can use for video.
If you watched the video it talks about aperture and ISO a lot so the next step would be to explain Aperture, ISO and Shutter speed. All components we need to know and be able to manipulate for a perfect picture.
Aperture
Aperture is our depth of field on the camera, the lower you set it the more washed out and short your depth of field on the picture will be, as displayed above an F-Stop of 2.8 lets in a lot more light and gives a shallow depth of field. The higher you bring your F-Stop the greater the depth of field is and less light enters the lense for a deep depth of field and a better picture.
ISO and Shutter Speed
The pictures kind of sum up the handiness of ISO but to explain properly ISO control's how much light enters the camera, the more light that enter's the "noisier" a picture will appear the less light that enters a picture the higher quality the picture will look, it's important to find the right balance so the image isn't too dark and isn't of a poor quality either.
ISO indicates your digital camera’s sensitivity to light. The higher the number, the less light is needed to take a photo that is correctly exposed.
In bright light (like the middle of a sunny day), you’ll normally use ISO 50 or ISO 100. These lowest settings can be used because there is lots of light around. However, in lower light, your camera needs some help.
There are two ways of doing this:
Decrease shutter speed: With a slow shutter speed the camera has more time to take in the amount of light it needs. This could however make your images turn out blurry because of how slow the shutter is.
Another way is to Increase your ISO: Rather than decrease the shutter speed, you can increase the ISO. As I said above, this will increase the sensitivity of the camera which means you can get the same shot with less light entering the camera. Thus the shutter speed can be kept low enough to avoid blurry images.
Auto Focusing and Manual focusing
This video explains Auto focus and manual focus and shows you the differences in both.
The video below this one is souly about auto focus and it explains in a little more detail how to get a good picture on auto focus and what you should do if you choose to use it.
