Transcript of MPEX Intro to DSLRs

Step Away from Auto Exposure Introductions Tripods
Allow for longer shutter times, crisper images, ‘tog in the shot.
Lens Filters
Can help prevent damage to lenses, and add level of creative control
Remote Shutter
Better than a timer for group shots, more stable on a tripod. Printing:
200 pixels per inch for large prints
300 pixels per inch for small prints
14MP (4600x3100) can produce 24”x16” prints
1200x1800 can still produce 4x6 prints.
Few images viewed online are larger than 1000 on a side (today). JPEG
Camera compresses RAW data
Some loss of “range”
Some loss of detail as compared to RAW (pixel peeper!)
Can’t undo camera post-processing
Easy to share with others
Noise reduction applied automatically
Smaller (2-8MB) Practice
Set mode to Shutter Priority (Tv or S)
Make a picture at 1/10s
Make a picture at 1/60s
Which one is blurry? Aperture priority (Av or A)
All the benefits of Program
You set Aperture, camera picks the other two

Shutter priority (Tv or S)
All the benefits of Program
You set shutter, camera picks the other two Stepping away from Auto Practice:
Set mode to Program
Set AF to Single Point
Set Metering mode to Partial or Spot
Make a picture where the focus point is in a dark area
Make a picture where the focus point is in a light area Stepping away from Auto Sanity Check--Do you know how to:
Charge and load a battery
Insert an unlocked memory card
Remove the lens cap
Turn the camera on
Compose a shot using the viewfinder
Change the zoom (focal length) Is this thing on? Taught by Rick Bennett Beginner DSLR 101:
The Basics of Digital SLR External Flash
Allows you to bounce light
More powerful for more distant subjects
Capable of remote triggering for professional look
Manual Flash
Cheaper, but need to understand manual exposure settings
TTL Flash
More expensive, more intelligent about exposure RAW
Uncompressed data straight from the sensor.
Easy to play with white balance afterward
More “range” in the image
Requires conversion before you can share with others
Noise reduction not applied in camera
Very large (14MB+) You can choose:
Auto, and let the camera make its best guess
Or you can try to pick the right one. Program mode (P)
Lets you choose focus points
Lets you choose exposure metering and white balance
Pick among “ideal” combinations of shutter and aperture Do you know how to:
Properly hold a camera?
Make a picture? Don't Shoot Yourself
(or do!) Tell us:
Your Name
How long you’ve had a DSLR
What you like to create images of
Your most burning question about photography What you perceive as white depends on the light source: sun, incandescent, fluorescent, daylight fluorescent, cool fluorescent, LED, mercury vapor, sodium The Camera Simulator
http://camerasim.com/camera-simulator/ Try this at home! ISO indicates the sensitivity of the sensor
Usually represented as “doublings” (or “halvings”) of 100, e.g. 200, 400, 800.
High ISO leads to more noise in the image Aperture limits the size of the light beam hitting the sensor
Measured in F-stops: f/5.6, f/8, f/22
Small F-stops (f/1.8) result in shallow depth of field
Large F-stops (f/22) result in long depth of field Shutter Speed limits the time light spends hitting the sensor. Usually measured in fractions of a second, e.g. 1/125s
“Slow” shutter can lead to blur (e.g. 1/15s)
“Fast” shutter can freeze motion (e.g. 1/1000s) Do you know what the operation mode dial is? So Many Dials Basic Camera
Operation Practice:
Set Mode dial to Automatic
Compose an image, activate shutter
Review Image on screen Low ISO High ISO Slow shutter Fast Shutter Small F-stop Large F-stop White Balance Matrix/Evaluative
Takes the whole scene into account
Spot
Evaluates the lighting at a single AF point Metering
Modes Focus Focus Modes
Single Servo:
Camera focuses once, and ‘locks’ with a half-press of the shutter release
ideal for stationary subjects, and recomposing after focus
Continuous Servo/AI-Servo
Camera keeps focusing as subject moves.
Ideal for moving subjects
Does not lock with half-press of the shutter release
Manual – you do all the work Practice:
Set mode to Program (P)
Set auto-focus to Single Servo
Set focus point to center
Compose picture with subject in the center, half-press shutter release, recompose with subject to the side, complete press. Your Image(s) Beyond the Kit Practice Practice Practice
Share with others
Seek feedback on your work
Remember: the most important part of the camera is the space right behind it. What's Next? Flash! Auto
Camera determines amount of flash to add
Might result in red-eye in dark situations and the further away the subject is.
Red-eye Reduction
Uses either pre-flash or AF assist to try to close irises on subject to reduce amount of red-eye.
Slow-Sync
Adds flash, but keeps the shutter speed slow enough to properly expose the background. Try it out: try setting your white balance to a couple of different settings, and take pictures around the room to see what it looks like.
