It was called Getting Back to Basics workshop. These workshops are great. We do learn a lot from each other. For instance, depth of field has always been a mystery to me. Honestly, when I shoot, I use the f-stop like a distance meter. I figures 5.6 – Hmmm, must mean about 5 1/2 feet away. Only, that’s not right either.
My camera is the first digital SLR that Canon put out. The Canon Rebel. Only 6 megapixels. Everybody else seems to have 10MP. I feel deprived. Oh well, let’s get to work.
Course Introduction
This workshop will be a review of the basic principles of photography, including:
- Exposure
- Aperture
- Shutter Speed
- Lighting
- Elements of design and composition
Exposure
- Photography=lighting
- Exposure is getting the right amount of light for you photo
- Use the exposure triangle
Exposure Triangle: Aperture
- Volume of light that reaches film or digital media
- Measured in f-stops (2,2,8, 4, 5.6, 8, etc)
- Smaller the f-stop (eg: 2.8) the larger the aperture
- Larger the f-stop (eg: 11) the smaller the lens opening
- As numbers increase, the light halves
Exposure Triangle: Shutter Speed
- Amount of time that the volume of light is allowed to reach film or digital media
- Normally, as settings increase the time is halved (eg: 1/30, 1/60, 1/125, 1/250)
Exposure Triangle: ISO
- Measure of a film or digital camera’s sensitivity to light
- Increase ISO 100 to 200, keep the f-stop constant, you can double the shutter speed
- Allows you to decrease exposure time in dark settings (eg: interior shots) for hand holding
- Default ISO is normally 100 or 200
- In some digital cameras, higher ISOs (above 800) can introduce noise
Aperture & Depth of Field
- Smaller the number= smaller the depth of field (sharpness) in the photo
- f-2.8=narrow depth, f-11= wide depth
- For portraits (people or things) shoot “wide open” – using small f-stop (eg: f-2.8) to get narrow depth of field
- For landscapes shoot use high f-stop number (eg: f-11) to get as much depth of field as possible.
Shutter Speed for Lens
- For sharper pictures, choose the right shutter speed for the lens
- Reciprocal of the film lens length
- For a 300 mm lens should use 1/300 sec minimum
Sharpness = Stability
- Become married to your tripod/monopod
- Tripods are best but monopods are portable
- Nikon/Canon SLRs use lens stabilization providing 3 to 4 f-stop advantage
- Sony/Minolta/Pentax SLR’s use in-camera stabilization. Provides 2 to 3 f-stop advantage, but every lens is stabilized (up to ~300 mm)
- Post-processing sharpening, apply via Photoshop (recommended for digital cameras)
Right Shutter Speed for Subject
- Freezing the Subject
- 1/500 to 1/1000 for fast moving parallel subject.
- PanningMove camera parallel to and same speed as the subject (eg. an athlete, race car, etc.).
- Shutter speed of 1/8 to 1/60 to blur background.
- Follow through (don’t stop panning after clicking shutter).
Right Shutter Speed for Subject
Freezing the Subject
Shutter Speed for Implied Motion
- Blurred subject / still background for implied motion
- eg. waterfalls, streams, car lights, joggers
- Use tripod and set shutter speed for:¼ sec for wind blowing trees
- ½ sec for waterfalls, streams
- 1/60 sec for speeding train
- 1 sec for hands knitting
- 8 sec for car light streaking
Shutter Speed for Implied Motion
Light
• Best Time To Shoot
Early morning (1st hour) or late afternoon light (last 3 hours) is the best time for photography.
Textures, shadows, depth in warm and vivid tone.
Change in weather patterns.
Harsh and flat light during other times of the day.
• Overcast
Better than shooting in direct sunlight.
Light
• Sidelight
Gives highlights and shadows and creates illusion of 3 dimensionality.
Additional exposure of -1 for digital.
• Backlight
Creates silhouettes
Easily done with sunsets.
To avoid having subject merge into surround-ing darkness, point telephoto lens at the bright
sky to right / left of sun and take exposure.Metering (Average & Centre)
• Average measures light & shadow and gives average reading.
Fine for subjects with equal shadow / light, otherwise can give faulty reading.
• Centre weighted measures reflected light from whole scene with bias to centre.
Put subject in middle of frame, meter and then recompose
Metering (Spot & Matrix)
• Spot measures light at narrow 10 – 50 and gets accurate reading for specific area.
Good for subjects that are light in primarily dark surrounding (or vice versa).
• Matrix has chip programmed to “see” and recognize subject and set exposure accordingly.
Accurate about 90% of time.
For digital bracket -2/3 f stop and compare.
Polarizing Filter
• Important accessory for landscape photos.
• Reduces glare on sunny days from reflective surfaces (water, glass, metal).
• Darkens blue in sky and enhances clouds.
• Use when at 900 angle to sun (ineffective if sun is right behind or in front of you).
• Rotate to get best effect.
• Use for sky and waterfall/river shots.
Polarizing Filter
Without Polarizing Filter
Neutral Density Filter
• Reduces brightness of light without impacting colour.
• Great for implied motion shots during sunny days.
• Comes in different grades – most popular are 0.30, 0.60 and 0.90 densities which reduce exposure by 1, 2 and 3 stops, respectively.
Elements of Design
• Line
• Shape
• Form
• Texture
• Pattern
• ColourElements of Design: Line
• Can be long or short, thick or thin.
• In nature, it is usually irregular (rivers, hills).
• Emotional impact on photos:
Curving lines are seen as restful, relaxing (surf, dunes, rivers). Try for “S” curve in pictures.
Jagged lines are forceful, chaotic, threatening (silhouette of mountain ranges).
Diagonal lines show movement, speed and give an “active” composition.
Elements of Design: Line
“S” curve
Elements of Design: Shape
• Often seen through silhouettes, using strong backlight or frontlight.
• Must have high contrast.
Elements of Design: Form
• Has 3 dimensions (Shape only has 2).
• Shows depth
• Photographed under sunny skies with sidelighting.
Elements of Design: Texture
• Needs low angled sidelighting to compose.
• Often created with macro lens.
Elements of Design: Pattern
• Repetition of lines, shapes or colours.
• Provides sense of harmony.
• Use flat even lighting and straight on camera angle.
Elements of Design: Colour
• Can be used to add impact to photo.
• Red, Yellow, Orange are “warm” colours – passionate / powerful.
• Blue and Green are “cool” colours – have a calming effect.
• Cool colours appear smaller than warm colours and they visually recede on the page so red can visually overpower and stand out over blue even if used in equal amounts.
Colour Wheel
Elements of Composition
• Fill the Frame
• Rule of Thirds
• The Right Third
• Frame in a Frame
• Portrait vs Landscape.
Composition: Fill the Frame
• You mind selectively sees what it wants.
• Check that what attracted you to the shot is filling the frame before you “click”.
• Move closer or use a telephoto.
Composition: Rule of Thirds
• Oft used compositional tool.
• Imagine a 3 x 3 grid superimposed on picture
• The grid is divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines.
• The four points formed by the intersections of these lines can be used to align features in the photograph.
• Aligning a photograph with these points can create more tension, energy and interest in the photo than simply centering it.
Composition: Rule of Thirds
Composition: Right Third
• Place primary object in the right third.
• Normally an eye enters the photo from the left and flows to the right.
• The eye seems to prefer a resting place on the right most of the time.
Composition: Right Third
Composition: Frame in a Frame
• Framing isolates / emphasizes the subject.
• Overhanging tree limbs, building doors and windows can all be used.
• Frames that colour contrast with subject are very effective.
Composition: Portrait vs. Landscape
• Horizontal:
– More static peaceful effect.
– Landscapes.
• Vertical:
– Suggest vigor, strength, power.
– Use for full length figures, tall buildings, etc.
Composition: Portrait vs. Landscape
