Research lighting in film

This is the research that written by Melissa:

There are some information from internet :

Soft front light / hot backlight

A popular technique in film lighting is to use a soft (diffuse) light source from the front and a stronger, more directional light from the  back, so that your subject has a hot edge. The soft frontal light is known as the fill light; the light at the back is known, unsurprisingly. As the backlight.

We can also arrange the lights to leave darkness between the area illustrated by the backlight and the area illustrated by fill light, just depending on how moody you want the shot to be. It is very hard to control, although the moodiest films tend to avoid leaving dark shadows on the faces of female talent.

If you want a different look, backlight can also be soft, but it should still be hotter than the fill.

And we should light our film or video shot by shot. I mean that when you relocate the camera to shoot a different angle, the light must be move as well to ensure the subject is always lit correct. I think it is very important, because audiences will feel involved in your film or video when you did light your film or video shot by shot.

Mixing color temperatures

Using different color temperatures can be used to great effect. This simply means using lights of different color in the same shot.

This was used to great effect by James Cameron in the steel mill scene of “Terminator2”, in which he used blue and orange light ( consistent with moonlight and molten steel respectively ).

The only caveat with this is. that you must determine the relationship between the two different color before filming, because it is not really possible, for example, to make the blue bluer without also making the orange bluer ( i.e.less orange )

Examples

1.Putting real film lights outside windows instead of relying on natural light - always worth it

Tips : Filmmaking is all about designing a look from scratch and then executing it on the shoot itself, which means that control is everything in filmmaking.

2. No color in your shots must ever be an accident

3. A beautiful blue can be achieved with HMI lights and a digital camera set to tungsten balance

4. A beautiful “Matrix” - style green can be achieve by shooting with regular florescent lights with the camera set to tungsten balance

5.Soft pools of light on actors’ faces can produce a very interesting look

There are three light sources in the shot: hot light from the back, dim soft light over the whole scene and a brighter soft pool of light in the top half of the singer’s face.

This shows how the most interesting discoveries in filmmaking are made while you’re actually shooting something, but it will only happen if you keep an open mind and are not too stressed.

6.Daylight-balanced light in the background with tungsten—light from the front, with the camera set on tungsten balance

The still below uses exactly the same technique, with a different subject ( a porcelain rose )

7.Backlight vs. no backlight

There two frames are taken from my first film: the first has no backlight and the second was shot with backlight ( a daylight-balanced Kino Flo):

Tips : The effect of backlight is clear: it increases contrast, reduces “muddiness” and enhances perceived sharpness.
