Exposure Triangle and Composition
- Shutter speed is how fast the lense snaps a picture.
- For an action photo you need a fast shutter speed to stop the motion. One two thousandth of a second is a fast shutter speed for a dslr.
- Bulb shutter is where the lense stays open; this is the slowest shutter speed.
Action shot bad example: shutter speed = 1/8 s
Action shot good example: shutter speed = 1/1600 s
Aperture/Depth of Field
- Aperture is the measure of how big the opening is that lets the light in.
- Another word for aperture is depth of field which is how much is in focus.
- The bigger the lense is open, the deeper the depth of field is. F22 is a deep depth of field, therefore the main object and the background is in focus.
- A shallow depth of field is F1.8. Using a smaller aperture/shallow depth of field can bring your attention to the main object of the photo and blur out the distracting background which can make your photo look way better.
- ISO is the measure of how sensitive the sensor is.
- Another word for ISO is grain.
- The higher the ISO, the more grainy the photo is.
- The lower the ISO, the picture is smoother.
Rule of Thirds
- Divide a photo into 9 equal sections by cutting the photo with 2 vertical lines and 2 horizontal lines.
- Place the main object of your photo on one of the vertical or horizontal lines.
- This places the main object a little off-center which makes your photo more interesting.
- Very important to the composition of a photo.
- Shooting from eye level can make your photo ordinary and boring
- Shooting from different angles like below, above, or close up makes your photo look more interesting.
- Add depth to give a 3rd dimensional look to your photo.
- Foreground,middle-ground, background.
- Our eye naturally follows lines in a photo
- A photo with leading lines leads us on a "journey" because the lines are going somewhere in the photo.
- Control where viewers eyes are drawn when looking at your photo.
- Diagonal lines, parallel lines, zigzag lines, 1 point perspective lines, etc.
- Enhances composition of a photo.
Fill the Frame
- Don't leave a bunch of empty space in your photo (this is a common compositional mistake).
- Zoom in more to fill the frame with the main object
- Balance a photo so that there is not an object on one side and a big empty space on the other side.
- Include objects of lesser importance with the main object to balance the photo.
- A loud background can distract your eyes from the main object of the picture.
- Take a picture with a solid colored background.
- Blur out the background by changing the aperture.
- Use natural objects like leaves, fences, archways etc. to frame your picture.
- Draws your attention into the main interest of the photo and away from the outside world.
Rule of odds
- Take a picture with an odd number of objects in it.
- It makes your photo look more interesting.
- An odd number of objects frames the center of the picture.
Space to move
- Don't take a picture with the main object or person walking out of the photo.
- Give your photo a "future" by leaving space in front of the object so the object has space to move into the photo.
- When we look at a photo we follow the gaze of the person or follow the direction on object is pointed.
- Always leave more space ahead of a photo than behind it.
