Spread the legs out and make sure the tripod is stable. Use the height from the legs before using the neck of the tripod. Put one leg forward and the two legs on your side.
Put the plate on the camera and make sure that the lens arrow is pointing towards the lens. Insert the plate into the locking mechanism and make sure that the camera is secure.
Use the camera timer and DO NOT TOUCH the camera or the tripod during the exposure.
Considerations for painting with light:
1. Use a tripod
2. Use Manual as the shooting mode.
3. Set the ISO to 100
4. Set the aperture to f/11 as a starting point to get a wide range of depth of field.
5. Set the shutter speed to 2″ as a starting point.
6. Use manual focus. Make sure the subject is in focus. To do this shine a light on the subject and use auto focus. Then flip the lens back to MF. Remember that if the distance of the subject to the camera changes, you need to refocus!
Mixing Flash with Painting with Light
The aperture controls the exposure of whatever is lit by the flash.
The shutter speed controls the illumination of the background.
Speedlites
1/1 is full power. This is the most light that the unit can emit. 1/2 power is one stop less or 1/2 as much light. And so on.
Using the unit at full power will make the recycle time longer, meaning it will take longer to recharge and be ready to fire again. Try for 1/4 power as the recycle time will be faster. Get closer if the light is not bright enough.
March 8 – Lighting and Mood – Please bring in a small stuffed animal to work with. Try to bring in a toy that is made out of cloth and not plastic as it will be less reflective. So a stuffed animal rather than an action figure.
Also, if you have a string of lights bring that too.

Review Shutter Speed
Shutter Speed is the length of time that the sensor is exposed to light to create the photograph. It is measured in seconds or fractions of a second.
The full stops for shutter speed are: 30”, 15”, 8”, 4”, 2”, 1”, . sec, ., 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000
Doubling the time, doubles the amount of light that reaches the sensor.
When shooting with a cameraphone and the Lightroom Photoshop app, you can set the shutter speed of your cameraphone between 1/10,000 and 1 sec.
The general rule for getting a sharp image is that the shutter speed should be 1/focal length. So a sports photographer using a 500 mm lens should use a shutter speed of 1/500.
A good rule of thumb when shooting with a camera is: Any shutter speeds slower then 1/60 require the use of a tripod. When shooting with a cameraphone, you will need a tripod to shoot at 1/15 or slower.
Image Stabilization can reduce blurriness when photographing a still subject in low light.
Turn off IS when mounting the camera on a tripod or photographing a moving subject..
Strobe Lights
Strobes
Strobes have two bulbs:
the modeling light which helps you see where the light will fall
the flash that fires when you press the shutter release
A trigger on the camera uses radio waves to tell the receiver to fire the light. The power pack stores the power used to make the exposure.
Strobe Lights or Flash-The exposure triangle does not hold because the shutter speed is effectively replaced by the flash duration. We adjust the exposure primarily with the aperture or the ISO.
Flash duration
Flash duration is how long the flash of light is that takes the picture. It is the amount of time that the flash head goes from on to off.
If you want to freeze motion with available light, it is the shutter speed that will do it.
If you want to freeze motion with flash or studio strobes it is the flash duration that counts.
The higher the power that you use, the slower the flash duration.
With our Dynalight strobes this is about 1/700th of a second at full power.
Sync Speed
Sync Speed-is the fastest shutter speed for which the shutter curtains are completely open at the time of exposure (or when the flash fires). For shutter speeds above sync speed, the shutter curtains are no longer fully open and so you will see the shutter itself in the photo as a black area. the sync speed for our class cameras is 1/200 sec.
Blurring motion
Blurred motion-moving elements blur with a longer shutter speed.

How to blur motion:
Use a tripod.
Use a slower shutter speed – 1/4 sec to 30″ or even longer
Direction-if the subject moves parallel to the picture plane there is more visible movement than if the subject moves toward or away from the camera.
Focal length-a subject will appear blurrier when photographed with a telephoto lens than when photographed with a wide-angle lens.

March 15 – Food Photography Basics – Bring a vegetable and something to put it on-a cloth, woven mat, a cutting board.
March 22 – Quiz 1, Toning Images
Quiz 1 – 4 pts. – Review weeks 1 – 5, Composition and framing, depth of field, motion, tripod use, lights and lighting. There will be 3 technical questions with a right or wrong answer and a compare and contrast of two photos graded on correct use of vocabulary.
Direct light or hard light – the rays of light are nearly parallel and strike the subject from one direction creating hard edged dark shadows with little detail. Examples: a spotlight, sun on a clear day, or a bare flash
Diffused light or soft light– the rays of light are scattered and coming from many directions. It appears even and produces indistinct shadows. Examples: overcast daylight, a light covered with tracing paper or other translucent material.

Light Direction
Front light comes from in front of subject from the camera position and the shadows fall behind the subject not concealing any details.
Side Light comes from 90 degrees to the camera. it adds dimension and texture to the subject.
Backlight comes from behind the subject towards the camera.

Rule of Thirds – Instead of placing the main subject in the center of the frame, divide the frame into thirds horizontally and vertically and place the main subject at one of these intersections.
Photographer: Michael Wu.
Diagonal Lines – lines that reach towards opposite corners of the photo
Leading Lines – lines in the photograph that lead the eye to the main subject
Photographer: Michael Kenna
Patterns – repeated elements. Break the pattern for visual interest.
Photographer: Edward Burtynsky
Symmetry – If you fold the image in half the two haves are very similar and have equal visual weight. Or make it asymmetrical to add tension to the composition.

Figure to Ground -the relationship between the subject and the background sometimes described as negative and positive space.
