Week 7: 09/11/2012

This week in the lecture we discussed lighting and how its position will affected pictures.

What positions of lights are there and what effect do they have?

Front lighting will cover the picture subject in light.

Side-lighting will create some shadows, this is good for drawing portraits.

Back-lighting will cover the picture subject in shadows.

A more in depth explanation of tall three:

Front light

Lighting a subject directly from the front removes quite a bit of depth from the resulting image. To accomplish a front lighting effect without losing your depth, have a light on each side of the camera, about 45 degrees upward, pointing down at the subject. This setup gives a wider front light that seems less intense and can preserve the depth of the subject.

Side light

Side light is great for emphasizing the shape and texture of an object. It clarifies an object's form, bringing out roughness and bumps. A blend between front and side light is common, as it communicates shape and form, while softening the flaws that direct side lighting can reveal.

Back light

Back light is wonderful for accentuating edges, and emphasizing the depth of an image. Back light often gives a thin edge of light around objects, called rim lighting, although it's hard to see it if the light is positioned directly behind the subject. Giving a foreground object a rim light will make it stand out from the background, accentuating the division in depth.

There is also:

Top light

Direct top light alone can make for a very sad and almost spooky feeling. Although we're used to seeing subjects lit from above (sunlight and most indoor lighting), there are usually other light sources filling in the shadows. Therefore, to achieve this effect, fill lights, if used, must be dramatically reduced in intensity.

Top-lighting

Bottom light

Bottom light is the light we're least accustomed to seeing. It has an intense impact when used, making objects look completely different and often sinister.

Bottom-lighting

We also spoke about how the higher the contrast on a picture the clearer it will look.

We then went to the Lab where we completed an exercise on editing a sound file to remove a unwanted sound and edit the file with effects to create the illusion of being in a room.

To do this I cut out the unwanted sound so only the speech was left. I then added a reverb onto the file to create to feel that the speaker was in a church or other large area.

I also increase the volume of the speaker to give the appearance that he was angry by making the sample louder and adding a fade in effect.
I feel the exercise was a success as ~I managed to complete it without any help and the file sounded great when it was done.
