History of photography
CAMERA OBSCURACamera obscura, ancestor of the photographic camera. The Latin name means “dark chamber,” and the earliest versions, dating to antiquity, consisted of small darkened rooms with light admitted through a single tiny hole. The result was that an inverted image of the outside scene was cast on the opposite wall, which was usually whitened.

MY CAMERA OBSCURA
ANNOTATIONS
How did you make the camera?
You first make a box with dark colours on the inside. Then you make a small square hole on one end. Then you put tracing paper over the other end.
What is focal length?
The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. A system with a shorter focal length bends the rays more sharply, bringing them to a focus in a shorter distance or diverging them more quickly. For the special case of a thin lens in air, a positive focal length is the distance over which initially collimated (parallel) rays are brought to a focus, or alternatively a negative focal length indicates how far in front of the lens a point source must be located to form a collimated beam. For more general optical systems, the focal length has no intuitive meaning; it is simply the inverse of the system's optical power.

Shutter speed
What is Shutter Speed? What does it control?
The shutter speed is the speed it takes light in when taking a photo
What is it measured in?
Shutter speed in measured in fractions of a second
What setting should the program dial be on.
The program dial is on TV.

what went well:
the shutter speed was perfect for each picture.
Even better if:
the pictures were more centred
The whole body was in shot.

Levitation
Yowa Yowa
Yowa Yowa would jump and pose in the air while she set a timer to take a photo of herself. This made the illusions of her levitating.
The task was to take a photo of you or your partner jumping so it looked like they were levitating.
Here is a gallery of my best images:

What ISO did you use
Lighting conditions were sunny.
What shutter speed did you have your camera on to achieve the best outcome?
The pictures were clear and not blurred because of the high shutter speed. Even better if we took more photos.
Tips that I would give about levitation photography are: make sure your camera is on burst and has a high shutter speed. Make sure your model jumps in a realistic way.

Francesca Woodman
Francesca Woodman intended to present urgency and movement. She did this by photographing a moving figure. She wanted us to think about representations of the body. Woodman is considering absence of presence and emotions in this piece of work. This is shown by photographing the pictures in an abandoned and isolated place. She wanted to explore her emotions and she wants to express how she feels. it is interesting in her picture, providence, Rhode Island, that it is a self portrait but you can not see her face and her upper body is blurred but her feet are in focuss.
Providence, Rhode Island. 1975-78

What went well:

Only certain areas of the areas are blurred.

Aperture
Depth Of Field
Depth of field is the area of focus within your image. A deep depth of field will mean most of the picture will be focussed. A shallow depth of field means only not all of the image will be focussed. e.g. if you want the background of a portrait to be blurred to stop it being distracting.
you can change the depth of field by changing one of three things:
1. aperture
2. focal length
3. distance from subject
The smaller the aperture opening, the greater the depth of field; the shorter the focal length, the greater the potential depth of field. Therefore, a wide-angle focal length at a small aperture diameter has much greater depth of field than a telephoto lens at the same aperture setting.

In this you had to take many photos and put them together into a stack on photoshop.
You had to have a deep depth of field.
What went well:
good speed of photos
quick, speedy and smooth transitions.
Even better if:
The scene had more movement in it
There were more slow and energetic movement.
