I choze this one because the veiwer would see the lines on the ground and then get led up to the building by the two corner lines on the building.
Next I chose this one because the waves coming from the ocean will lead the veiwer torards the city.
Last I choze this one because i was just simply amazed after i saw what this photo looked like befor ike came in. He just totaly wiped the road away clean. I would say the ground has a way of leading the veiwer towareds the houses... that are suprizingly still standing after a bad hurricane blue threw.

weather-phenomenon- I chose this one because the rays of the sun mixed with the cirrus clouds makes lines that could lead the veiwer to the dark buildings and the sun itself.
Northern_lights- I chose this one because the light rays come from the sky pointing down and so will lead the veiwer to the trees on the ground.
colosseum_rome- I then choze this one because of the bridge over the walls leads the veiwer towards the far away exit after the bridge crossing.
Yarra_Park- I then chose this photo because there are many shapes in it. But the reson is the long, large road that will lead the veiwer towards the city.
Sun_Rays- Last I chose this one because the rays through the clouds will catch the veiwer's attention and lead him towards the sea.

The reson I chose this one is because the storm cloud makes a c curve that leads the looker to the rain. And the road leads him to the light of the sky behind the storm cloud.
Next, I chose this too because the very first thing the looker will get his attention on is the wooden crossway.
I then chose this photo because the rain hitting the table are forming lines, so the veiwer would follow the rain then see the table.
Then I chose this one because the light poles,road,and buildings on both sides will lead the veiwer towards the building in the center of the photo.
Next I chose this one because the wood on the floor and the wood plank both lead to the worker at the desk.

Negative-noting an image in which the brightness values of the subject are reproduced so that the lightest areas are shown as the darkest.
(Google result) Negative-a negative may refer to three different things, although they are all related.
My explination for why the positive and negative are what they are is known as ''color reversed''. For the negative, the black areas are in the sky and the white is on my ground. And for the positive, objects on the ground are black and the sky is white, which is the correct look alikes. So I think the negative's colors are upside down and the positive's are right side up. *Note- It's like someone in the universe took earth, put it in the wash machine, washed it, and with it tumbleing in many derections, the colors got mixed up. Making the colors in the wrong areas back down on earth! But I'm very interested in the negitive/positive therory!

Aperture-An aperture is a hole or an opening through which light travels. More specifically, the aperture of an optical system is the opening that determines the cone angle of a bundle of rays that come to a focus in the image plane.
Shutter-shutter is a device that allows light to pass for a determined period of time, for the purpose of exposing photograghic film or light-sensitive electronic sensor to light to capture a permenant image of a scene. A shutter can also be used to allow pulses of light to pass outwards, as in a movie projector or signal lamp.
Exposure-exposure is the total amount of light allowed to fall on the photograghic medium (photograghic film or image sensor) during the process of taking a photogragh. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance over a specifed area.
Depth of field-depth of field (DOF) is the portion of a scene that appears acceptably sharp in the image. Although a lens can precisely focus at only one distance, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions.
F-stop-of an optical system expresses the diameter of the entrance pupil in terms of the focal length of the lens ; in simpler terms, the f-number is the focal divided by the ''effective'' aperture diameter. It is a dimensionless number that is a quantitative measure of lens speed, an important concept in photograghy.
Focal lenghth-of an optical system is a measure of how strongly the system coverges (focuses) or or diverges (defocuses) light. For an optical system in air, it is the distance over which initally collimated rays are brought to a focus. A system with with a shorter focal length has greater optical power that one with a long focal length; that is, it bends the rays more strongy brining them to a focus in a shorter distance.
