world upside down

i have chosen this image because many people just look straight through it and dont really realise that the sign is there for a reason. Thats why i like this picture because with out the writting at the bottom it looks real;ly funny.

i took some time to focus onto the image but when i was there it went alright.

my second image is a photo of graffiti, i chose this image because no one ever looks up close at it. this also simbolises that the car park lifts are used for teenagers to graffiti. people are use to the environment with graffiti on it.

the image came out dark as i couldnt set the aperture and shutter speed.

camera obscura

what did you see while you were inside the camera obscura?

while we were in the camera obscura, at first we couldnt really see anything as our eyes were trying to get usto the light but then after acouple of minutes we started to see some objects moving. after some more time we could see buildings and more details.

how is this camera obscura similar to the inside of a camera?
how it is different?

the camera obscura is similar to a camera because the light is coming through a little hole just like a camera hole, the light will come through the hole and form an image upside down.
it is different because the camera obscura does not involve a camera.

why was the image upside down?

the light travels in a straight line and the light goes through a little hole thats why the top of the iamge becomes the bottom and the bottom becomes the top.

slr camera notes

first way to control light into a camera is slower shutter=more light to hit the film

second way is through aperture:
smaller aperture=less light
larger aperture=more light.

1 second=slow
1/30=fast
1/1000=very fast

lower the number larger the aperture
higher the number smaller the aperture

shutter speed- aperture- observation

1/60- f/8- blury

1/60 -f/5.6 -blury

1/30 -f/5.6 -blury bright

1/60 -f/22 -dark

1/60 -f/16 -dark

depth of field:

background

forground

smaller aperture=greater depth of field.

larger aperture=smaller depth of field.
