one major way that DSLRs are different from consumer “point and shoot” cameras or phones: detachable lenses
- prime vs. zoom lenses
- kit lens
- prime lens: only one focal length
- zoom lenses: variable focal lengths
- Kit lens a basic lens that comes with a camera body in a “kit,” usually not too expensive
- Metaphors to understand how exposure is determined:
- garden hose
- International Organization for Standards – number that describes film’s sensitivity to light
- formerly ASA (American Standards Association)
- Now used to describe sensitivity of digital sensors in digital cameras
- HIGH ISO value means the sensor will be MORE sensitive to light, meaning it will take LESS LIGHT to get the right exposure
- choose the correct ISO for your shooting situation
- more available light = lower ISO
- less available light = higher ISO
- BUT use the lowest ISO you can to avoid grain/noise
- shutter speed: how long the shutter is open
- on the Canon T6i ranges from
30” (seconds) to 1/4000 of a second
- choose shutter speed based on situation:
- higher speed to capture fast action
- but what is the tradeoff?
- The shutter in a camera is a half circle 180 degrees
- So your shutter speed should be double your frame rate
- Typical NTSC frame rate is 30 frames per second
- Shutter speed 1/60 of a second
- How is a lens defined/ described?
- Prime or zoo,
- Focal lengths
- Maximum apeture
This is a surrealistic picture and was created by Salvador Dali. He is the father of surrealism hes really famous for his paintings and making melted watches and clocks. This picture is surrealstic because theres like a branch on that branch theres a Shattered camera and another camera on the side. ON the bottom theres a little branch holding up the plate and theres two eggs on the plate. On the top of everything is a snail and it looks as if its looking into the camera.
In this picture the angle that was taken was really low. The photographer made good composition with blurring the clouds. The photographer made a low shot make the tower look really big on the bottom. At the top the photographer made it look really small and a bit taller. They got the shot right to see the whole bottom of the tower too. If you didnt know this is the eiffel tower. The Eiffel tower was made in 1887 january 28. The Eiffel tower was made of puddle iron. the eiffel tower stands tall in Paris France and has been there since day one. They have made some adjustments to it like the big screen that wasnt there when it was first built. The photographer had to really get down to get the shot of this angle. The editing was perfect with the colors tones. He used great composition and he also made it to where the tour was focused on. The trees and the background was blurred a bit and it was almost like an eye catcher for the Eiffel Tower. The photographer got the shot really clear and messed with the color scheme in his editing skills. He also had to block some things out in the back and make the shot really focused. They kind of blurred it at the bottom if you can tell and it gets more clear up. The Eiffel tower does have an elevator so you can go up there and see all of paris france. If you can see on the legs of the tower theres a lot of the puddle iron but in the middle of each leg is a elevator. People can tour up there or even sometimes people come to take pictures. Like the photographer a lot of photographers come here to take pictures and then later edit the photo and post it to the internet.
