Types of Digital Cameras

▪ 3 Main classifications

– Point and Shoot

– Prosumer

– Digital SLR

Page 8: Basic DSLR Photography and Videography for AITians

Point and Shoot digital Cameras (P&S)

▪ Commonly referred to as “consumer” digital cameras.

▪ Represent probably 90% of all digital cameras on the market

▪ Typically small, compact and lightweight

▪ Targeted at broad majority

▪ Typically very User-Friendly

▪ Image Quality has improved drastically

Page 9: Basic DSLR Photography and Videography for AITians

Prosumer Digital Cameras

▪ Common term used to describe advanced models of P&S (now also used to describe many entry level DSLR's)

▪ Similar in shape and appearance to Digital SLR's

▪ Typically have extended zoom range (8-12X)

▪ Typically combine user friendly P&S features with more advanced manual features.

Page 10: Basic DSLR Photography and Videography for AITians

Digital SLR (DSLR)

▪ SLR Stands for Single Lens Reflex

▪ Have larger sensors, resulting in greater image quality

▪ Tend to favor manual control

▪ Much larger and heavier

▪ Ability to interchange system lenses

Exposure Modes

▪ There are several modes available which offer a combination of automatic and manual controls.

▪ Auto, sometimes represented by an A, or simply a green square, is fully automatic functioning. True “point and shoot” where the camera decides all the settings for you

Page 19: Basic DSLR Photography and Videography for AITians

The Shutter Speed

▪ Shutter Speed

– How long the shutter remains open, exposing the image sensor to light.

– How long the camera “sees” the picture

– Measured in Seconds, from 30 sec to 1/8000 sec

– The more the shutter speed (bigger denominator of the fraction – the lesser time light is allowed to enter the camera), the lesser the exposure.

30 sec …. 10 sec…. 1 sec …. ½ sec …..1/5 sec …. 1/10 sec … 1/25 sec ... 1/100 sec ...1/500 sec ……1/2000 sec …. 1/4000 sec …1/8000 sec

Shutter Speed is getting higher

The image is getting darker

Less amount of light is allowed to enter in the camera

Shutter opens and closes quickly

Page 20: Basic DSLR Photography and Videography for AITians

Shutter Speed

▪ Fast Shutter Speeds (600 and up) are used to stop motion and will freeze the subject.

Page 21: Basic DSLR Photography and Videography for AITians

Shutter Speed

▪ If the shutter speed is such a low value that the object or camera moves/changes position before the shutter closes, you will get “Motion blur”.

▪ Slow Shutter Speeds (1/60 or slower) can be used to portray movement or speed

Page 22: Basic DSLR Photography and Videography for AITians

Shutter Speed▪ Very Slow Shutter Speeds (5 sec. or slower) can be used in very low light

situations to obtain correct exposure, or achieve dramatic effects.

As your shutter speed decreases, your chances of getting a blurry image increase because you must hold the camera steady for a longer period.Maximum zoom is hard to hold camera steady for a sharp pictureSlowest shutter speed without a tripod is 1/focal length of lens

Page 23: Basic DSLR Photography and Videography for AITians

Slow Shutter Speed Fast Shutter Speed

Page 24: Basic DSLR Photography and Videography for AITians

Slow shutter speed Fast shutter speed

Page 25: Basic DSLR Photography and Videography for AITians

Panning

▪ During the exposure, the camera is moved in the same direction as the subject.

▪ Resulting in a reasonably sharp subject and a blurred background

Page 26: Basic DSLR Photography and Videography for AITians
Page 27: Basic DSLR Photography and Videography for AITians

Movement Compensation

▪ Refers to the cameras ability to correct small movements by the user while taking a picture, in order to reduce the blur caused by camera shake.

▪ Represented differently by different companies:

– Nikon – VR – Vibration Reduction

– Canon – IS – Image Stabilization

– Pentax – SR – Shake Reduction

– Sony – SSS – Super Steady-Shot

Page 28: Basic DSLR Photography and Videography for AITians
Page 29: Basic DSLR Photography and Videography for AITians

Moving Object Shutter Speeds - NO Blur

▪ Which shutter speed to use for subjects depends on 3 factors:

– How big the object appear in the frame

– Which direction it is moving

– How fast it is moving

Page 30: Basic DSLR Photography and Videography for AITians

Moving Object Shutter Speeds - NO Blur

Page 31: Basic DSLR Photography and Videography for AITians

Moving Object Shutter Speeds – For Blur

▪ Blur can be used to emphasise movement

▪ Amount of blur depends on speed of movement of subject and shutter speed

Shutter Speed (sec)

Subject Moderate Blur Extreme Blur

Person Walking 1/30 sec ¼ sec

Person Running 1/60 sec 1/15 sec

Horse Trotting 1/30 sec 1/8 sec

Horse Galloping 1/125 sec 1/30 sec

Page 32: Basic DSLR Photography and Videography for AITians

The 3 Pillars of Photography

–Shutter Speed

–Aperture, f-stop

– ISO

Page 33: Basic DSLR Photography and Videography for AITians

Aperture – f/stop

– Size of the lens opening - Controls the brightness of light that reaches the film

“STOP” – refers to a change in exposure, whether the shutter speed or aperture is changed

one “stop” more exposure means to double the light reaching the film

one “stop” less exposure means to half the light reaching the film

• Each f/stop number can be though of as the bottom part of a fraction

• The larger the f/stop number, the smaller the lens opening

• f/11 is a smaller opening than f/4

f/1.4 f/2 f/2.8 f/4 f/5.6 f/8 f/11 f/16 f/22

Page 34: Basic DSLR Photography and Videography for AITians

For example, if you shoot at f/stop 5.6, and then change it to f/8, you are letting exactly half as much light strike the film or sensor.

Page 35: Basic DSLR Photography and Videography for AITians

f/stop

f/stop is getting higher

The image is getting darker

Less amount of light is allowed to enter in the camera

Size of lens opening is getting smaller

f/1.4 f/2 f/2.8 f/4 f/5.6 f/8 f/11 f/16 f/22

Depth-of-field is increasing

BUT

The area of a scene from foreground to background that will remain acceptably sharp when we focus on a subject is called the depth of field.

f/22 provides more depth of field than f/4

Page 36: Basic DSLR Photography and Videography for AITians

You determine what you want to draw your viewers attention to.

“shallow depth of field”

f/4

Focus Point on b

Page 37: Basic DSLR Photography and Videography for AITians

“increased depth of field”

f/22

Page 38: Basic DSLR Photography and Videography for AITians

Depth of field

▪ Compare depth of field at f/3.5 and f/22.

Page 39: Basic DSLR Photography and Videography for AITians

Smaller aperture (f/22), deep depth of field Larger aperture (f/4), shallow depth of field

A wide aperture (small #) will give a shallow DOF which can be used to isolate a subject.

Page 40: Basic DSLR Photography and Videography for AITians

Depth of field Depth of Field is not divided equally

You should note that Depth of Field is roughly divided 1/3 in front of where you are focused and 2/3 behind where you

are focused

Page 41: Basic DSLR Photography and Videography for AITians

The 3 Pillars of Photography

–Shutter Speed

–Aperture, f-stop

– ISO

Page 42: Basic DSLR Photography and Videography for AITians

ISO

▪ Measure of sensitivity of your camera to light.

Page 43: Basic DSLR Photography and Videography for AITians

ISO: General Rules and tips

▪ ISO settings are often rated at 100, 200, 400, 800, 1600, and even 3200 on some models

▪ Use an ISO of 100 or 200 when taking photographs outside in sunny conditions.

▪ If the sky is overcast or it is evening time, or in a darkened room, then use an ISO within the range of 400 to 800.

▪ Night time or in cases of low light you might need to set your digital camera ISO to 1600. If not your photo will appear too dark, if at all.

Using High ISO values causes the sensor to produce much more heat, which creates digital “noise” in images.

Page 44: Basic DSLR Photography and Videography for AITians

ISO Setting

▪ ISO measures the sensitivity of the image sensor. The lower the number the less sensitive your camera is to light and the finer the grain.

▪ Set the lowest setting possible to avoid noise

ISO 100 ISO 3200

Page 45: Basic DSLR Photography and Videography for AITians

ISO Setting

Page 46: Basic DSLR Photography and Videography for AITians

The fourth Element - White Balance

▪ White Balance is essentially the camera compensating for the color cast of the light in order to reproduce the “correct” colors.

▪ The color cast of light is referred to as its Color Temperature and is rated in degrees Kelvin

▪ Ranges from “Cool” to “Warm”

▪ Most Digital cameras have Automatic White Balance, but also specific options for different sources of light.

Page 47: Basic DSLR Photography and Videography for AITians

Part 1: DSLR Photography▪ The basics and 3 Elements of Exposure (shutter

speed, aperture and ISO)

▪ Lenses and Focal Lengths

▪ Summary

▪ A Quick “Settings” Slideshow

Page 48: Basic DSLR Photography and Videography for AITians

The lens• Light rays strike the subject and reflect in all

directions.• The light hits all parts of the sensor,

everywhere, in a uniform pattern.

• We need to find a way to aim that light to form an image.

Page 49: Basic DSLR Photography and Videography for AITians

The focal plane

▪ A central question for photographers: do you want your subject to be a larger part of the frame, or a smaller part?

▪ One way to change this is to move forward or backward.

▪ A second way is to change the focal length of the lens.

• The point of convergence of refracted light is called the focal point.

• The focal point may be adjusted so that it is exactly at the same point as the film or sensor.

• This is called “in focus.”

Page 50: Basic DSLR Photography and Videography for AITians

Refraction points

▪ Some lenses bend light quite sharply. These are said to be “short” or “wide-angle” lenses.

▪ Others bend light more gradually, These are “long” or “telephoto” lenses.

Page 51: Basic DSLR Photography and Videography for AITians

Zoom lens

▪ Focal length is the measurement of the space between the lens and the focal plane, expressed in millimeters.

– 18-55 mm lens

– 55-250mm lens

– 18-135mm lens

▪ A lens that is capable of changing focal length is called a “zoom lens.”

▪ A fixed focal length lens is sometimes called a “prime” lens.

– 50mm lens

– 70mm lens

– 300mm lens

▪ Most zoom lenses sacrifice speed for flexibility. Also, they may be less sharp.

Page 52: Basic DSLR Photography and Videography for AITians

Focal length and Zoom

▪ If a focal length is short, the image takes up less space on the focal plane (sensor or film).

▪ If it is long, the image takes up more space.

▪ Therefore, a long lens brings us closer to the subject, like a binoculars.

▪ The focal length of the lens is usually stamped on the lens barrel or ring.

Page 53: Basic DSLR Photography and Videography for AITians

Perspective

▪ Here is a comparison of perspectives.

Page 54: Basic DSLR Photography and Videography for AITians

Wide angle and telephoto

▪ 28mm (wide angle) and 105mm (telephoto). Note sign is about the same size.

28mm (wide angle) 105mm (telephoto)

Page 55: Basic DSLR Photography and Videography for AITians

Telephoto stacking▪ A telephoto, or long focal length, lens gives appearance that objects are

closer together. You’ve probably seen this startling effect on photos of airplanes that seem to be landing right on the highway.

Page 56: Basic DSLR Photography and Videography for AITians

Wide Angle Lens vs. Telephoto Lens

Page 57: Basic DSLR Photography and Videography for AITians

Focal Length

Page 58: Basic DSLR Photography and Videography for AITians

Depth of field (Effect of focal length and distance)

▪ Depth of field is directly affected by three things:

– F/stop

– Focal length

– Camera-to-subject distance

Page 59: Basic DSLR Photography and Videography for AITians

Depth of field and focal length

▪ If you have a wide-angle lens, your focus can be fairly sloppy and you can still get a sharp photo.

▪ If you are shooting with a telephoto, depth of field is shallow. Not much beyond the actual subject will be sharp.

Page 60: Basic DSLR Photography and Videography for AITians

Depth of field and focal length

Page 61: Basic DSLR Photography and Videography for AITians

Depth of field and camera-to-subject distance

▪ When you get closer to a subject, the depth of field becomes more shallow.

▪ When you get really close, depth of field may be nearly zero. That is why a macro (close-up) lens requires careful focusing.

Page 62: Basic DSLR Photography and Videography for AITians

Macro and depth of field

▪ Here is a close-up at f/4.5 and f/19.

Page 63: Basic DSLR Photography and Videography for AITians

Depth of field in P&S Cameras

▪ Simple point-and-shoot cameras without a focus mechanism often have normal or wide-angle lenses.

▪ This is because with these lenses depth of field is large, commonly between 5 feet and 15 feet (1.5 meters to 4.5 meters).

▪ This means you can snap a subject anywhere in that area and be confident it will look sharp.

Page 64: Basic DSLR Photography and Videography for AITians

The Lens Specifications - f/stops and focal lengths

▪ The longer the telephoto lens, the bigger in diameter it has to be to obtain the same f/stop.

▪ To obtain f/2 with a 200mm lens, you need a diameter of 100mm.

▪ This is why “fast” telephoto and zoom lenses become big heavy pieces of glass, and why they usually cost a LOT of money.

▪ The fastest lens (lowest f/stop) in theory, is 1.0 f/stop. That doesn’t exist, but 1.2 f/stop does. For a price.

▪ Regular zoom lenses that offer a wide range will have a smaller possible f/stop number at the telephoto end than at the wide-angle end.

– Stamped on the barrel will be something like f/3.5 - f/5.6 or f/4 – f/5.6

Page 65: Basic DSLR Photography and Videography for AITians

The Lens Specifications - f/stops and focal lengths

▪ Here are standard f/stops:

– 1.4, 1.8 (or 2), 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45.

– No one lens offers this entire range.

▪ Usually the lens speed, or widest possible f/stop, will be stamped on the barrel. Also depth of field at different f/stop and focus combinations.

▪ Some cameras offer a depth-of-field preview button. This shows you in your viewfinder what will be in focus.

Page 66: Basic DSLR Photography and Videography for AITians

Aperture: General Rules and tips

▪ A larger lens opening (f1.8-3.5) offers the following advantages:

– Allows you to shoot more often with just natural lighting helps to reduce harsh shadows and red-eye caused by flash.

– Allows more light to pass through, the camera will be able to choose a slightly higher shutter speed helps to reduce motion blur.

– Helps to reduce "depth-of-field“ (for effect).

Page 67: Basic DSLR Photography and Videography for AITians

How to read a lens

▪ Zoom is 18-55mm.

▪ Speed is f/3.5 (at 18 mm) to 5.6 (at 55mm).

▪ VR means Vibration Reduction.

▪ G means no aperture ring.

▪ AF-S means Auto Focus-Single.

▪ And of course, the model name is Nikkor DX.

▪ Some cameras also include filter size.

Information you need is usually stamped on the front ring.

Page 68: Basic DSLR Photography and Videography for AITians

Why a fixed focal length?

▪ Most of us use zoom lenses nowadays, but fixed focal lengths (prime) have advantages:

– They tend to be sharper.

– They tend to be more simple in construction, so more trouble-free.

– They are cheaper.

– They are usually faster—the biggest reason they remain popular.

– What is “fast?” Anything lower than about f/4.

Shutter Speed and Aperture

▪ To get a correctly exposed picture, you need a combination of shutter speed and aperture

– Each shutter speed lets in twice as much light as the next faster speed

▪ 1/60 lets in 2x as much light as 1/125

– Each aperture setting lets in twice as much light as the next smaller opening (larger-numbered setting)

▪ f/4 lets in 2x as much light as f/5.6

Page 78: Basic DSLR Photography and Videography for AITians

Shutter Speed and Aperture Reciprocity

Similar to reciprocity, ISO numbers either halve or double the sensitivity to light

i.e. 1/30s shutter speed @ 100 ISO = 1/60s shutter speed @ 200 ISO

Page 79: Basic DSLR Photography and Videography for AITians

Shooting Modes (Canon and Nikon)

Canon Nikon

Page 80: Basic DSLR Photography and Videography for AITians

Scene Modes

▪ Scene Modes are basically fully automatic modes designed specifically for a certain situation.

▪ They typically place emphasis on one or more settings based on the typical circumstances of the situation chosen.

– Portrait – large aperture, small DOF

– Landscape / Mountains – small aperture, large DOF, focused around infinity

– Sports – Short shutter speeds to freeze movement, probably large aperture

Page 81: Basic DSLR Photography and Videography for AITians

Camera Exposure Modes

▪ Auto / Program – Not the best for low light

▪ Shutter Priority – Tv or Shutter Priority allows you to choose the shutter speed while the camera chooses the aperture which would produce the correct exposure

▪ Aperture priority – Av or Aperture Priority allows you to choose the aperture value while the camera chooses the shutter speed required to obtain a correct exposure

▪ Manual – Full creative control! :)

Page 82: Basic DSLR Photography and Videography for AITians

Metering Modes

▪ The metering system within a camera measures the amount of light in a frame and determines the best exposure.

▪ Many cameras have more than one metering mode and each evaluates a scene in a different way.

▪ Essentially, by changing the metering mode you are telling the camera to evaluate the scene in a different way.

Some Principles– Un-clutter the picture. Zoom in.

– Put subject off-center / Rule of thirds

– Use of frames, lines & diagonals

– Dramatic Perspective

– Unusual camera angles

– Frame your photo with foreground objects.

Some Principles

Page 148: Basic DSLR Photography and Videography for AITians

Take Vertical Pictures

▪ Many subjects look better in a vertical picture

▪ Make a conscious effort to turn your camera and take vertical pictures

Wasted Space

Page 149: Basic DSLR Photography and Videography for AITians

Use Auto Focus

▪ Center the subject

▪ Press Shutter Button halfway down

▪ Re-Frame your picture

▪ Finish by Pressing the Shutter Button all the way down

Page 150: Basic DSLR Photography and Videography for AITians

Stabilize

▪ Tripods

– Use for sharp images

– Eliminates shake

– Get a stiff tripod

– Great for close ups

Page 151: Basic DSLR Photography and Videography for AITians

Light▪ Avoid using flash, even for night shots, The indiscriminate

blast of flash destroys the intimate mood of existing light

▪ Side Lighting instead of front or overhead (noon-time) lighting

▪ Use fill-in flash, for backlit situations or overhead sun, camera auto exposure is sometimes confused

Page 152: Basic DSLR Photography and Videography for AITians

Traffic Trails

▪ Once you master all settings, you can play with them !!!

Page 153: Basic DSLR Photography and Videography for AITians

Light Explosion

▪ Light Explosion / Motion blur With an SLR – zoom the lens during a long exposure

Page 154: Basic DSLR Photography and Videography for AITians

Out of Focus

▪ Bright, colourful pinpoint light sources work best (try illuminations?)

Page 155: Basic DSLR Photography and Videography for AITians

Painting with Light

Page 156: Basic DSLR Photography and Videography for AITians

Painting with Light

▪ Use a small torch or sparkler to “draw” on images.

▪ A short burst of flash can also be used to illuminate objects / people if you draw around them

Page 157: Basic DSLR Photography and Videography for AITians

Funfairs

Page 158: Basic DSLR Photography and Videography for AITians

Fireworks▪ Concentrate on aerial rocket displays for best result

▪ Best view is further back, behind the crowds. Elevated position good if you can find one.

▪ Try to fill the frame as much as possible

Page 159: Basic DSLR Photography and Videography for AITians

Recommended Settings for Fireworks

▪ Set small aperture, e.g. f/16

▪ Use a wide angle (28-35mm) to capture the whole of the display

▪ Use a telephoto (50mm+) to fill the frame with firework explosions

▪ Using the Bulb setting, open the shutter for 2-60 seconds - hopefully to capture multiple fireworks

▪ Can open the shutter for longer if you block the light with your hand or a black card between fireworks – longer gives a much more impressive picture

File Format

▪ Refers to the way the computer stores the data

▪ More common formats include:

– JPEG (Most widely used, can compress image data, Do not edit JPEG images in photo-editing programs to minimize data loss)

– EXIF (a variation of the JPEG format, Stores extra data as metadata with the image file)

– TIFF (Tagged Image File Format, Does not compress as much as JPEG, Choose when picture quality is more important than file size

– RAW (Does not include any in-camera processing features, Provides a truer version of the scene in front of the camera, Large file size

Page 190: Basic DSLR Photography and Videography for AITians

Camera RAW

▪ An important feature of DSLRs is the ability to store images in RAW format.

▪ JPEG format color corrects, sharpens and compresses the image information and so takes some control away from the photographer.

▪ RAW records image directly as the sensor sees it, without processing.

▪ It allows photographers to use all the digital information gathered by the sensor.

▪ The photographer does the processing in Photoshop.

Resolution

▪ Number of pixels captured by the image sensor.

Neutral Density (ND) filters

▪ We can reduce the amount of light entering the lens with a Neutral Density (ND) filter.

▪ This is useful if we want to shoot with a wide aperture on a bright day.

ND4 (1-stop) Graduated ND Fader ND

Page 196: Basic DSLR Photography and Videography for AITians

What Shutter Speed should be used for Film Making?

▪ The shutter speed of each frame is limited by the frame rate. (Shooting) at 24 fps, the LONGEST exposure possible is 1/24s.

▪ To mimic the appearance of film, shoot as close as possible to half your frame rate. E.g. at 24 fps, set your shutter to 1/50s.

▪ You can increase your shutter speed, for a stroboscopic, choppy appearance (e.g. Gladiator).

Page 197: Basic DSLR Photography and Videography for AITians

What f-stop should be used for Film Making?

▪ Depends on how far your subject or you will move in that particular scene.

– Parties

– Sports

– Presentations and Class Lectures
