=== What is the relationship between ISO and f/stop(aperture) and shutter speed? === The difference in the main three elements photography is that they all focus on different things. ISO focuses on the light. ISO is basically the opening in the lens of the camera, depending on how much it opens or closes, the light will be different in the photograph. If there is a picture being taken in the dark, the lens is is opened more so it can absorb as much light as it can to get a clear picture. Aperture is how much of the picture is focused, if there is a picture of a flower being taken using a micro lens, it will not be able to have the entire frame in a clear picture, only a section of it will be clear. The shutter depends on the kind of picture being taken. If there is a sport picture being taken, the shutter speed it very fast, the lens “blinks” fast to capture one stage of movement. If the shutter was any longer, it would capture more than one frame in one picture, the photograph will be very blurry. If a picture of a city skyline at night is being taken, the shutter speed is very slow to absorb all of the light and still result in a clear picture. All of these elements are very important and they all depend on each other, but they are all different. Large DOF Small DOF

**A: What is depth of field and how does it relate to lens focal length and aperture** On optics, particularly as it relates to film and photography. Depth of field. Also called focus range or effective focus range. Is the distance between the nearest and farthest object in a scene that appear acceptably sharp in an image. A 200mm lens focused at 12ft will have a wafer-thin depth of field compared to a 20mm lens focused at 12ft. With a wider lens you would have to move closer or further away depending on what lens you use. Focusing distance plays a part on the overall effect, with wide apertures offering considerably more depth of field when focused on a subject far away than they do when focused on a subject that’s close to the lens. **V: Vocabulary you should know** Exposure ISO Aperture Shutter Spee d Depth of Field Rule of Thirds Framing Frame Filling Horizontal Lines Lead Lines FOCUS Light

What is the relationship between ISO and f/stop(aperture) and shutter speed?
ISO, aperture and shutter speed are all apart of the exposure triangle, they are all very important because they all affect the photograph. If one changes, the others will change, they are not three different settings, they build off of each other. They are all different though, ISO is the camera's sensitivity to light, the aperture is the opening and closing of the lens, how much light is let into the camera. Shutter speed is how fast or slow the window in the camera is open to capture the shot. If the aperture was set to a larger opening, the shutter speed would slow down as well to capture all that it was “seeing” and the ISO would most likely go down. If one of these factors on the exposure triangle change, they all change.

What is depth of field and how does it relate to lens focal length and aperture

DOF is how much of the photograph is focused. For example, a picture of flowers using a micro lens will have a small DOF because it cannot capture the entire frame, only one small section of it will be in focus. This depends on how wide the lens is, the aperture. If the lens is open super wide, it is nearly impossible to have the entire frame in the focal point. When the aperture is smaller, more of the frame gets into focus. Then again back to the exposure triangle, when one things changes, everything else will change as well.

Connections to your own work and your own experiences. What does it remind you of? The behaviors of the lens are very similar to your eye. The shutter is how fast you blink, the aperture is how wide your eye is and how much of what you are looking at is in focus and ISO is the size of your pupil letting in a certain amount of light. Although the difference is in cameras, to focus the frame, half clicking the shutter button will put the picture in focus. I do not have a lot of experience with different lighting because I have never really photographed inside, I am very used to natural lighting because I take most of my photographs outside. Although your camera needs to change in the settings of it depending on the lighting you are photographing in. In the menu there is a tap that says ISO settings, there are many different options for what lighting is being used. Lastly, there are 5 different compositional techniques to remember while photographing. Fill the frame, horizon line, framing, rule of thirds and leading lines. Filling the frame is making sure there is no negative space in the photograph, so the entire frame has something to look at. Second the horizon line in photography is very important, it makes photos much more appealing and gives them much more depth. If photos were to be crooked, it should be exaggerated and intentional. Framing is also used to make photos more appealing. It put the subject in a focal point and draws more attention to it. Many photographers use this when they want to emphasize something in the frame. Rule of thirds in my opinion is one of the most important rules in photography. Placing the focal point in one third of the frame makes them much more appealing and pleasing to the eye. If a photograph is centred, it is simply just not as interesting as a picture using rule of thirds. Lastly leading lines, these lines are in the photo to make your eyes look all over the frame, but they are being lead by a line. They direct your eyes through the photograph.

ISO, aperture and shutter speed are on the exposure triangle. What these are is ISO is the cameras light, aperture is how wide the lens is and Shutter speed is how fast you take the picture. If the aperture is not the wide then the shutter speed will be faster than if it was wider. Then that would make the ISO be lower because since the lens is more close not much light is getting in making the ISO lower and then the shutter speed like I said before will be faster.

What is depth of field and how does it relate to lens focal length and aperture

Depth of field is how focused the photograph is.If looking at the exposure triangle when one thing changes, that changes everything else. Like if you were to take a picture of something close up you would want to have a small DOF because the camera can’t capture the whole frame so only a small part of the picture will be fully focused. All of this relies on how wide a lens is which is the aperture. If let's say the lens is not winded all the way then it's more likely that the whole frame will be in the focal point and more of the picture will be focused. If the lens is really wide then it will be really hard to get the whole frame in the photo.

Connections to your own work and your own experiences. What does it remind you of?

This reminds me of running. The faster you run is like the shutter speed. When you are running slow you can see more things around you and it takes slower to finish but when you run faster you capture the moment and you will get done faster. The aperture is how far you are in front of someone. When you are farther ahead you are more focused. ISO is like the oxygen when you breathe. When you run fast makes you infront of people which makes you breathe harder. They are all connected just like shutter speed, aperture and ISO. Me personally I haven’t really experiences anything with cameras. I have just loved taking pictures. But I do know that making sure your photo is focused it really important. On the cameras we use you can just A for auto or M for manual. And If you pick M you can with your hand focus the camera on your own.

What I have learned is while taking pictures make sure to focus on the 5 different compositional techniques, Fill the frame, horizon line, framing, rule of thirds and leading lines. Filling the frame is making sure there is no negative space, in the entire frame has something to look at. The horizon line makes photos much more appealing and gives them much more depth. Framing is also used to make photos more appealing. It put the subject in a focal point and draws more attention to it. Rule of thirds, placing the focal point in one third of the frame makes them much more appealing and pleasing to the eye. If a photograph is centred, it is simply just not as interesting as a picture using rule of thirds. Leading lines, these lines are in the photo to make your eyes look all over the frame, but they are being lead by a line. They direct your eyes through the photograph.
