Below is my visual evidence for Task one.
Camera and Lighting skills
When creating a film whether it be on set, or in an outdoor location, there are simple things that need to be taken into consideration. With in this report I’ll discussing some basic skills covering – Light, Lenses, Recording Media and Colour.
Light is needed on a regular basis. If the sun, or electricity, weren’t around to give us light so that we could see – our eyes would only see darkness, since we don’t have nocturnal eyesight. This is no different for filming.
However setting up lighting, especially in a studio setting, so that the footage can look like it’s being light naturally, can be a difficult if not done correctly, and with out consideration. A similar problem can take place if the light is not strong enough, then the camera will not be able to pick up detail correctly.
A good place to begin would be the ‘Inverse Square Law’
It may sound like a complex system when really it’s actually very simple. The Inverse Square Law dictates, “When light is further away, the fall off light is greater”.
In a nutshell the further away the light source is, from the filming subject, the greater coverage from the light. As shown by the diagram above – though the light covers more of the set, the light is not as intense the further it moves back. Below is a video that shows the ‘inverse square law’ in action (1:20 – starts explaining).
And here is a video of myself, and fellow student, putting the inverse square law in practice to prove the theory.
Another consideration is ‘Knowing your lens’. There are whole ranges that come in different lengths and sizes; therefore affecting what can be seen in the shot – and even effect the presentation of a shot.
Some of the most commonly known Lenses are as followed.
The most narrow of the Lens range is the Telephoto, which is at the measurement of 135mm giving the shot a ‘shallow depth of field’. This lens is very good for real close up, and tight, shots.
Then there is the Human Eye, which is at a measurement of 50mm, and this lens shows a shot – as the name says – the way a human eye can see. This lens is very good for mid close up shots.
And finally there is the Wide Lens, which is a measurement of 28mm – this lens presents the shot at a Wide angle capturing a lot of the set. This lens is very good of capturing a lot in a scene.
Once the appropriate lens has been chosen then the next thing to consider is the altering of Exposure, and the Aperture, on a scene.
The Exposure is about the amount of light in a scene. The Aperture, which functions act similar to an Iris, is what’s on the lens to help us control how much light comes into a scene. As we know light helps us to see everything – however too much light and we can’t see – and the same with not enough light.
Another thing to consider when working with wondering about the depth of field (the amount you want in the shot, and what you want to focus on in the shot.)
Technology has advanced over the years, and the film industry is no different.
Currently there are two ways to capture film – Tape and Memory card. Both versions get the job done however memory card is better because there’s more space, and unwanted footage can be deleted. While on tape you have to keep on filming until you reach the end, you can’t delete unwanted footage and try again.
When going to capture your footage you need to know, most importantly, what setting your going to set your camera to – this can be done via digital camera.
One of the first things to consider is frame rate, and shutter speed. There are different frame rates for each part of the world – they need to be set correctly other wise the footage will not look good quality.
The most common in England is 25fps for TV alone, there for the shutter speed on the camera is 50. (The shutter speed is always double the fps.) The reason why shutter speed is so important, is because the faster the speed is – the less blurry any motion movement (e.g. Car scenes, Fight scenes) will look. However what need’s to be remembered is that the faster the shutter speed, the less light that will be allowed into the shot – there fore affecting your shot.
When filming, apart from getting the film captured, is to try and make the footage look as if it’s something you would see every day.
Though exposure needs to be taken into consideration, as each type of light (sunlight, red heat lamp light, etc) each one will have a different intensity.
