ISO measures the sensitivity of the image sensor.
The same principles apply as in film photography – the lower the number
the less sensitive your camera is to light and the finer the grain.
Higher ISO settings are generally used in darker situations to get
faster shutter speeds (for example an indoor sports event when you want
to freeze the action in lower light) – however the cost is noisier
shots. I’ll illustrate this below with two elargements of shots that I
just took – the one on the left is taken at 100 ISO and the one of the
right at 3200 ISO (click to enlarge to see the full effect).
EV - Exposure Value, usually
means the ability to override the auto exposure system to lighten or
darken an image.
Depth of Field - depth of field
(DOF) The range of sharp focus. Controlled by the
focal length and aperture opening of the lens. A large aperture yields
shallow DOF. Smaller apertures
yield deeper DOF.
Diaphragm- The technical name for the lens
aperture thats made from overlapping
blades.

ISO - Film speed (the measure of a photographic film's sensitivity to light) is designated by a single, almost universally-accepted common system developed by the International Organization for Standardization which uses the initials “ISO” before the film-speed number - e.g. ISO 100.
EXPOSURE VALUE - The Exposure Value (EV) system, which originated in Germany in the 1950s, was created to be a simple-to-use substitute for the shutter speed/aperture combination, using a single number instead of two.
DIAPHRAGM - A ring or plate with a hole in the center that controls the amount of light entering the camera. An adjustable diaphragm in a lens controls the size of the hole, or aperture, thereby permitting more or less light to pass through the lens to the film.
SPEED - A measure of the sensitivity to light of a photographic emulsion (combination)
DEPTH OF FIELD - The range of distance in a scene that appears to be in focus and will be reproduced as being acceptably sharp in an image. Depth of field is controlled by the lens aperture, and extends for a distance in front of and behind the point on which the lens is focused

ISO: The ISO setting on a camera tells how sensitive the image sensor is to light. If the ISO is at a hight setting, the image sensor is more sensitive and allows you to take pictures with very low lighting. Lower ISO settings are preferred in situations where there is very bright light. This is simply another way to adjust the camera instead of using aperture or shutter speed.
EV: EV stands for Exposure Value and denotes all of the possible combinations of shutter speed and aperture that can be used to give the same exposure to a picture.
Aperture: The aperture on a camera refers to how much light will be let into the picture depending on the size of the hole that is letting light into the camera. With shutter speed, it determines how exposed the picture will be with relation to light. The higher the aperture, the smaller the hole and the less amount of light that will be let into the camera.
Shutter Speed: Shutter speed also deals with exposure and determines how long the shutter of the camera will be open to let in light. In bright lighting, the shutter speed should be low, otherwise the picture will be underexposed. In low lighting, the shutter speed should be longer to allow more light to come in. However, the longer the shutter speed, the more likely the picture will be blurred if the camera is not sitting on a flat surface or a tripod. Also, moving objects will become blurry if they are shot with a longer shutter speed.
Depth of Field: The depth of field deals with the sharpness of the photograph. Cameras are able to make the entire picture entirely in focus. However, playing with the aperture can change the depth of field. It allows certain aspects of the picture to be in focus and other parts not in focus. The more shallow the depth of field, the less amount of the photograph will be in focus. Increasing the aperture increases the depth of field. Here is a picture I took last week that shows depth of field:

This is a great picture of a forest. The photo shows many lines with the trees, there is also a lot of depth.
Another great photo that shows a bathroom. Both my pictures where taken by Mark Power.

2nd Week Posting by Cibelli117
This is my best portrait photo I took in class last week. I feel like the lines in my picture are straight and I liked the lighting and how I placed him off center.
This was my attempt to bring the statue to life. I like the contrast in colors and I really liked how I got the sun shinning in the background. I wish I didn't cut off his head though.
This was my best picture of depth of field. I like the angle and, I thought it looked better in black and white.
The two photos were by Photographer Mark Power. The similarities between his photos are the high level of exposure and vertical lines.

A New Photographer:
Cornell Capa was a LIFE photographer. He covers social issues, religious traditions...
In these images, it seems that Capa has roughly 3 visual lines. He has two vertical and one horizontal. There is generally one vertical line on the left hand side of the photo, and another somewhere toward the middle/right. The horizontal line goes through the top half of the photo.

I spent a lot of time last week taking depth of field pictures. It took me a while, but I finally found some that I like.
And I also got a picture of the statue that I really liked. At first it was a little difficult to make it appear alive, but then I put my settings to black and white and I loved it!

The front of the picture (the first statue) is in focus and the rest of the photo is blurry because of the depth of field.
Another Photographer: Abbas.
Abbas is an Iranian who moved to Paris. He used to photograph political situations in other parts of the world but has moved to photographing religion and its role in international conflicts. The below pictures both seemed very similar in design to me, but have entirely different meanings. The first is more political and was taken in South Africa and the second refers to religion and was taken in Indonesia. The lines in both are really similar and I like how one is dark and the other is light.
Photos I like from last Class (and the one above):

I like the colors in this picture and how the flower is in focus and the background is blurrier (depth of field)
I don't know why I like this one, but I do. I know it cuts of her hand but I like the space above and the contrast in colors.
I like the lines in this picture (the door).
This is another example of depth of field
I was also asked to post a picture that I took the first week I was here. I took it at St. Peter's and I really like the light coming into the photo. The contrast is good in black and white. The picture isn't perfect, but I like it.

Terminology-LH
Iso: The speed or specific light-sensitivity of a camera is rated by ISO numbers such as 100, 400, etc. The higher the number, the more sensitive it is to light. As with film, the higher speeds usually induce more electronic noise so the image gets grainier.
Diaphragm: a type of leaf shutter consisting of a number of thin blades which briefly uncover the camera aperture to make the exposure.
Speed Setting: The speed at which a digital camera's shutter exposes the image sensor to light.
Depth of Field: Depth of field describes the areas of the main focus point that remain sharp, or in focus. With an extremely shallow depth of field, even areas just in front of or behind that point will be out of focus. With a wide depth of field, much of the photograph may be crisply in focus. Depth of field is affected by factors such as aperture and focal length, although subject distance and sensor type can come into play as well.

In his photos, the photographer Sergio Larrain uses a vertical line that is centered in the pictures and a horizontal line that is placed 1/3 from the bottom of the picture.
Constantine Manos
Looking through the photography of Constantine Manos it can be seen that there are two lines he usually works with. His two lines are typically diagonals that intersect forming a triangle. It is this triangle that becomes the focal point for his images.
Comapring Larry Towell Photos
Larry Towell stuck out to me among the other Magnum photographers, not for his photos but because of his bio. It stated that his business card reads "Human Being," that traveling is a huge priority for him, that being a poet and folk musician affects his style and that he tries to capture intimacy . When I looked at his photos I also noticed they presented a theme of people (usually in very small numbers) with the backdrop of the setting in which they live. There are a lot of fields, trees, snow-natural aspects of a person's inhabitance, effecting the ways in which they live.
These two photos really stuck out to me because of the subjects they both posses. Both have a focus on the one child and both children seem to be negatively effected by the living situation they are in. Also, both photos play with the theme of capturing light, shadows and darkness cohesively. The different architectural aspects of each indoor space also heavily effects the photo. Both have most of their light source coming from the upper right hand corner. It seems that in both, the light represents a hope for what is outside waiting for them, beyond the immediate poorer conditions in which they are currently in.
The first was taken in Ontario, Canada, 1992 and the second was taken in El Salvador, 1991.

These 2 photographer were taken by Alex Soth. I like them because they are both taken when it is very cold outside and I like the way the snow looks. This first picture is almost completely white except for the bright hanging laundry. It makes a horizontal line across the photo and the color catch your eye.
The second photo is showing a cross with Jesus on it. The cross appears to be sitting on top of a hill, and the cross and the wires form a nice triangle.
Martin Parr
I chose these photos because I think they are so interesting. This is not the type of photography I am interested in, nor is it something I would ever purchase, but I love looking at it. I think it is funny that some people would look at these photos as art. The pictures below present a common theme, people at the beach.
In the first photo, you can see horiziontal lines with the chair, the ladies arm, and her leg. I do not see very many vertical lines, but possibly the bracelet and the watch on her hand. Tere is also a triangle that develops with her swimsuit and in the bottom right corner with the chair. The second picture also has more horizontal lines than vertical lines. The horizontal line are created with the woman's neckline, her eye goggles, and her hands abover her head. The vertical line could be her head and the towel. Looking at this artists other work, I do not believe that there is a continual theme and style with the pictures. Instead, I think this photograph likes to be different and kind of switch it up a bit, because all of his photographs are so weird but entirely different.
