Three Main Elements for Photography
The opening/closing of the door that allows light inside your camera.
Controls the SIZE of the opening the light will pass through into the camera
A bit more different to understand
The film or sensor's sensitivity to light
Basically how fast the sensor can absorb the light
When everyone shot in film we called
The Perfect Triangle
Introduction to Photography
Why Not Auto modes?
Specific Auto Modes
Portrait - Close up of people - blurs background
Landscape - Wide view and sharpness of a place
Child - Shows bright colors + faces
Sports - Freezing action
Close Up - Shooting tiny things
Effects & Scene Modes
1. Shutter - Door
2. Aperture - Lens opening
3. ISO - Light sensitivity
Used in order to create
How much light is allowed onto the film or sensor in order to create an image.
The sound you hear when you take a picture. It will sound faster or slower depending on the setting
Measured as a fraction of one second
1/30 (30) or 1/60 (60)
Lowest shutters for hand held shots without camera movement
controls the motion
Viewfinder will show as whole numbers such as 60, 125, 250 or 500 but they are actually fractions: such as 1/60 of a second or even 1/2000 of a second. You can allow for the shutter to stay open as long as you wish.
Faster shutter speeds FREEZE action
A smaller fraction of a second
1/150 or 150 in your viewfinder is necessary
As long as you have enough light
Slower shutter speeds BLUR action
A larger fraction of a second
1/15 or 15 in your viewfinder will blur movement
Allowing motion to blur can create a sense of drama, movement, artistic expression
Your camera will make the exposure decisions based on which one you select. It will be an average of all possibilities - often leaving the image also looking average.
Night Portrait - shows person and background
Night Landscape - use tri-pod to see street lights
Party/Indoor - shows background, similar
Beach/Snow - for bright high-contrast scenes
Sunset - emphasize rich colors, no flash
Dusk/darn - similar to sunset
Pet Portrait - action mode for pets
Candelight - no flash
Blossom - more in focus, small aperture
Autumn Colors - makes reds and yellows richer
Food - boosts colors
Silhouette - turns front images dark
High Key - when areas very bright
Low Key - when areas very dark
For many who want off auto the alternate auto modes are a big step for your photography and a good place to start.
Best way is to practice and experiment with changing different modes and comparing the results.
Measured in f-stops
f/2.0, f/2.8, f/3.5, f/8, f/22
There are several in between
The smaller the number the bigger the opening
Part of your LENS for your camera.
Two lenses can zoom far but if one opens to a 2.8 it is about $1000 more than one that only opens to 3.5
International Organization of Standardization
The higher the ISO number the faster the light hits the sensor BUT the more ISO - the more fuzzy images look
The lower the ISO the more sharp an image looks but you must have enough light or the image will be dark.
A correct exposure (good picture) is a simple combination of three important factors: aperture, shutter speed, and ISO.
You set the ISO and the camera will make all the other decisions
You must manually pop up your flash
Gives you a bit more control
Good place to start.
You set the shutter speed and the camera controls everything else
Good to use for outdoor sports.
Flexible to make certain changes you couldn't on the auto action mode.
You set the aperture and the camera makes the other decisions
Good to use when shooting in low light and need aperture to be large
Also good to use when you want everything in focus and use a small aperture
Same flexibility as S mode
You must set everything.
Focus on the big three
Must use your LIGHT METER
Your camera will tell you if you have enough light to get a good exposure
As you look through your viewfinder you see the light meter graph line
Should be located below your image and will adjust as you change aperture or shutter
Using natural light correctly
Understanding White Balance
Shooting in Manual Mode
Think of ISO as a worker bee. If my camera is set for ISO 100, I have, in effect, 100 worker bees; If your camera is set for ISO 200, you have 200 worker bees. (2 cameras) The job of these worker bees is to gather the light that comes through the lens and make an image. If both of our cameras are set with the same aperture opening, who will record the image the quickest, you or me? You will, since you have twice as many worker bees at ISO 200 than ISO 100.
BUT we will have different shutter speeds. If you come in faster, you need 1/250 but I will need 1/125, a slower shutter because it will take me longer to gather the light for the image.
However, the higher the ISO the more visual NOISE you will see within your image
Avoiding White Noise
In order to stop taking blurry images that are crisp with great color we will cover:
When you take a picture, you are really taking an exposure
Turn your camera dial to M for Manual
Turn camera on and look through
Look at the numbers across the bottom or side. Write them down how they are in your viewfinder.
