Introduction To Digital Photography

noreply@blogger.com (Harsha) — Sun, 12 Feb 2012 04:45:20 PST

Why Digital ?

Conventional Photos Can Be Scanned
Film Cost

Digital "Film" Is Expensive But Reusable

No Processing Required

Review and Playback Gives Immediate Feedback
Permanence Of Digital Data Can Be Excellent ( e.g., Color Reference Is Preserved )

Exposure

How Much Light Energy Does The Sensor Process ?
A Function Of 4 Things:

Available Light... Which Is Hard To Control

Shutter Speed

Aperture Of F/Stop

"Film" Speed ( Sensor Again )

Generally, If Available Light Is Constant, Other Parameters Trade-Off

Exposure: Shutter Speed

The Time Period During Which Light Is Sensed
2X Time Is 2X Light Energy
Speed Usually Range From About 1 Second To 1/1000s
Things Moving Faster Than Shutter Are Blurred ( and That`s Everything If You Move The Camera. )
Under 1/30s, Brace The Camera ( e.g.., Use Tripod )

Exposure: Aperture , F/Stop, or T/Stop

How Much Light Is Admitted ( Transmitted ) By The Lens
Larger Aperture Is Smaller F/Stop number; 2X Steps F2, 2.8, 4, 5.6, 8, 11, 16

Exposure: Film Speed EI, ISO, ASA

Light Measured By Electric Charge, Amplified, and Digitized
Higher Is More Sensitive ; 2X Steps 50, 100, 200, 400
Higher Implies More Amplification, Hence More Noise
Moderate Underexposure Correctable With Higher Noise : Moderate Over Exposure Clips ( Looses Detail In ) Highlights
Example Equivalent Exposures:

E1 50, 1/250s @ F2.8
E1 50, 1/15s @ F11
E1 200, 1/60s @ F2.8

Exposure: Film Speed & Sensor Noise

Photographic Effects

Focal Length

Shorter Means Wider Viewing Angle

Sensor Size Varies, So Quote 35mm Equivalents ;

Wide Angle Is < 43mm ( e.g., 35mm )
Telephoto Is > 43mm ( e.g., 135mm )

Depth Of Field

Depth Of Field Is Distance Range That Is Sharp
Smaller Focal Length Increases Range
Higher F/Stop ( Smaller Aperture ) Increase Range

Depth Of Field

Depth Of Field ( Click Image To Enlarge )

Photographic Effects : Flash

A Pulsed Light Source Synchronized With The Shutter
Give Fast Exposure Without Enough Ambient Lighting, But Easily Yields Images Of Poor Quality
Flash Has A Limited Useful Range, Images Look Flat
Red Eye And Red-Eye Reduction Flash Modes
Fill-in Flash And Flash With Slow Shutter Speeds
Bounce Or Otherwise Soften Flash Lighting

Photographic Effects: Fill-In Flash

Photographic Effects: Fill-In Flash ( Click Images To Enlarge )

Image Capture: Sensor

CCD Or CMOS Arrays With RGB Or CMYG Filters; Foveon R-G-B Sensor Stacks
Analog Readings Converted To 8, 10, Or 12 Bit Digital
Each Light-Sensitive Position Is Called PIXEL ( 1.5-3M Pixels Is Roughly Comparable To 35mm Film )
Grain Is Mostly Noise, But Also Sensor Pixel Count
Sensor Noise Is Less When Cold
Sensor Noise Is Less For Fast Shutter Speeds

Image Capture: Sensor Filters

Image Capture: Sensor Filters ( Click Image To Enlarge )

Image Capture: Overexposure

Loss of highlight detail; possible local distortion of color

Image Capture: Overexposure ( Click Image To Enlarge )

Image Capture: Speed & Sensor Noise

Conventional Film has reciprocity failure problems;
for digital, very long times increase sensor noise

Image Capture: Speed & Sensor Noise ( Click Image To Enlarge )

Image Capture: Storage Media

Types: CF, Smart Media, Memory Stick, XD,etc
Capacity From 4MB To 1GB, With 50KB, To 2MB Per Image

Image Capture: Resolution and Image Quality

Resolution ( Of The Sensor ):

Some Sensor Pixels Are Used As A " Black Reference "
Can Interpolate Sensor Data To Any Image Resolution

Image Quality ( Compression ) Settings:

JPEG Images Are Interploated And Compressed
JPEG Works Better With Higher Resolutions
Even " 100% Quality" JPEGs Are Imperfect

TIFF Images Are Interpolated, Saved 24 Bits/Pixel RGB
RAW Formats Save Sensor Data To Process Later ( e.g., 12-12 Bits/Pixel One Color )

Image Capture: Resolution & Image Quality

JPEG compression is effective for photos ( Click Image To Enlarge )

JPEG is more effective at higher resolutions
Both 100% and 50% 256x256 better than 100% 128x128

Image Capture : Color Balance

Color Reproduction And Perception Is Tricky Stuff
Use Manual White Balance Where Possible
Can Fix Later ( Best Using RAW Format )

Color Balance ( Click Image To Enlarge )

Digital Darkroom Techniques

Done With The Lights On, No Nasty Chemicals
Can Do Some On - Site Using In - Camera Preview, Options
Corrections:

Fixing Underexposure Increases Noise: Overexposure Clips Highlights, Information Is Lost
Adjust Color, Contrast, Dodge/Burn
Can Fix RedEye, Remove Unwanted Objects, etc.

Cropping : Sensors Are 4:3 Or 3:2, Not 7:5, 10:8, 14:11, etc.

Digital Darkroom Techniques : Printing

Various Printing Techonoligies:

Dye Sublimation: Highest Quality, Expensive And Slow
Inkjet : Good Quality ( With The Right Paper )
Laser: Fast and Cheap Per Print

Does The Monitor Match The Printer ?
Want More Than 1000 Pixels Per Inch For Printed Image

Advanced / Specialized Darkroom Techniques

Remove / Replace Backgronds
Panorama Stitching : Create Larger, Hi-Res Image From Multiple Low-Res Images
Correction Of Lens / Perspective Distortions: Can Undo Barrel / Pincushion Distortion, Logically Tilt The Lens, etc.
Various Special Effects ( To Use Sparingly ) : Page Curl, Tiling / Mosaics, "Old Photo" Effects, etc.

Non - Traditional Uses ( Of Images )

Images For The WWW

Download Time Matters; Keep Image File Size Small ( Generally, 640X480 Or Lower Resolution )
Use JPEG, GIF, Or PNG Compression

Image Archiving :

CD Or DVD as "Archival" Storage... ( Many DVD Players Can Show JPEGs From A CD )
Can Easily Make Slideshows On Videotape, etc.

Non- Traditional Uses ( Of The Camera )

The Camera Is A ( NTSC/PAL ) Presentation Device:

Can Do Slide Shows Of The Umages
Upload And Then Show Any Images ( Often, Cameras Are Picky About Image Format )

Visual Note-Taking: Photography Where You Parked, Notes On A Chalkboard, etc.
