Digital Photography 101:

Some tips for nonprofessionalsBill Hackett, Cheshire Cat Photo

3 Things to decide

• JPG or RAW

• Tripod, monopod, or handheld

• Multiple exposures with bracketing or single exposures

Equipment

• Cameras and lenses

• Tripods and monopods

• Computers and software

• Canon - Excellent lenses, leads in electronics, prompt repair

• Nikon - Excellent lenses, durable bodies, premium prices

• Others - Choose on basis of lens and image processor

Cameras (and “camera backs”)

The lens

• Length - 50mm “normal” lens, 70-200mm telephoto zoom, 10mm wide-angle

• Speed - f/1.4, f/2.8, f/4-5.6 (higher numbers = “slower” lenses)

• Quality (Chromatic aberration, sharpness, etc.)

Tripods and monopods

• Tripods are more stable than monopods (“3 points determine a plane”)

• Monopods are convenient and can be better than nothing (handheld)

• Choose a heavy (and tall enough!) tripod with fewer leg segments, “flip-lever” (rather than “turning ring”) locking, and quick-release head. Use a “cable release” or infrared (IR) device to trip shutter!

Platforms

• Macintosh - Choice for security, stability, and scalability, since UNIX-based. Most viruses are not written for Macintosh, but you should STILL use firewall and antivirus

• Windows PC - Use Windows 7 and the best antivirus and firewall package available.

• Others (Android, iPhone, iPad) - Screen size is limiting for the phones. Excellent camera in iPhone. iPads might be an option for processing.

Software

• Adobe Photoshop and Bridge, Adobe Lightroom

• Adobe Photoshop Elements

• Apple iPhoto and Aperture

Photographs

• Kinds (and Sizes!) of files

• Workflow

• Storage and Backup

Photographs: Kinds of Files

• JPG and PNG - JPG is destructive (“lossy”compression); PNG is lossless

• TIF (TIFF) - uncompressed and L-A-R-G-E

• cRAW and DNG - camera RAW and Adobe “Digital Negative”

Workflow

• Dictated by your end-product - What are you trying to produce?

• Must fit your needs - “KISS” (Keep It Simple, Stupid! :-) ) Methodology

• Must make “sense” - Retain all of the picture information that you need

Workflow Tips

• Never lose photo information - store a file that has everything you’ll need later

• Adjust exposure, white balance, and sharpness of RAW files first, then color

• The “Level” and “Cropping Tool” are your friends!

Storage and backup

• Store photos on >1 PHYSICAL device (no “single point of failure”)

• Back up your work regularly and as frequently as makes sense

• Back up important work at >1 physical LOCATION (e.g. at home and office; at home and online storage)

Organization

• Computer “Folders” (Directories) by date and mnemonic name

• Spreadsheets - Excel, others

• Data bases - I use Filemaker, the #1 data base for Mac and the #2 for PC

Shooting

• Philosophy

• Light

• Composition: framing and cropping, settings, exposure, focus, and depth-of-field

Philosophy

• ‘Would you tell me, please, which way I ought to go from here?’ ‘That depends a good deal on where you want to get to,’ said the Cat.

• What is there to DISCOVER? (NOT: “What is there to photograph?)

• In photography, we order the chaos around us, emphasizing one aspect of the world, ignoring all others, representing that subject in a way that shows how it has engaged us emotionally.

Light

• “Photography” literally means “painting with light”

• Dull light = dull photographs, regardless of subject matter

• Light has a direction, a character, and a color

Light direction

• Frontlighting - Wipes out any shadows; WORST for landscapes and BEST for tight shots of birds and animals

• Sidelighting - Shadows emphasize shape and texture; early morning and late afternoon sidelighting for landscapes

• Backlighting - Outlines shapes by creating glowing halos or even silhouettes

Light character

• “Hard” or “Soft”

• Hard = Direct bright sunlight or “head-on” camera flash; Produce sharp-edged black shadows from “point source” of light; Sensor (and film) cannot capture the RANGE of exposure

• Soft = Low-contrast lighting; Great for closeups and delicate color; Shadows disappear or are diffused, depth perception is limited, colors saturate

Light color

• Warm reds and oranges early and late in the day

• Cooler blues at midday

• Overcast makes lighting cooler; Cool light can emphasize snow and frost but you may need to “filter” (or digitally adjust white balance [light temperature degrees Kelvin!]) for brightly colored subjects

Composition

• SLOW DOWN! Take your time. The light on your subject is changing constantly!

• Vertical or Horizontal (“Portrait” or “Landscape”)

• Framing and Placement (keep in mind “aspect ratios” of later frame sizes); Yet another reason for using a tripod; Avoid “cutting off” the subject with the edge of the frame; Zoom lenses; “Rule” of “thirds”

Exposure

• “Exposure is the major problem facing all <film> photographers.” - John Shaw

• Exposure of RAW images can be adjusted, so... it is not as big a problem!

• Correct exposure means that tonal values turn out the way that YOU wanted

Aperture and Shutter Speed

• Aperture = the size of the hole: f/1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16

• Shutter Speed = time the hole is open (in seconds): 2”, 1”, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000

• With Aperature-priority, you size the hole, and the camera picks the speed; With Shutter Speed-priority, you pick the speed, and the camera sizes the hole; With Full Auto, the camera picks both (and the camera’s “brain” is SMALLER than OURS! :-) )

Focus and depth-of-field

• Focus is the region of sharpest definition

• Depth-of-field is the depth of this region

• Aperture-priority: large holes = shallow depth of field, small holes = greater depth of field

Good Vibrations?Only in the heart.... All other vibrations are BAD for Photography!

Presentation

• Digital: cell phones, Internet email, Facebook, Web sites, Digital frames

• Prints, photo gifts, CDs and DVDs

• Digital slideshows

Digital

• Portability

• Worldwide reach

• “Just-in-Time” production of prints and gifts, on demand

Physical

• Prints - Wallet sized to large posters, canvas, metal, etc.

• Disks - CDs are approximately 700 MB; DVDs are approximately 4.7 GB; “thumb drives” (USB “sticks”) come in a variety of sizes, use solid-state storage

• Gifts - playing cards, puzzles, keepsake boxes, coasters, tiles, clothing, etc.

Are YOU serious? :-)

• Shoot ONLY cRAW (“Camera RAW”)

• Use a tripod whenever reasonable

• Shoot multiple exposures per setting and “bracket” your settings (... and prepare to spend HOURS and DAYS at the computer with your work.)

“The Road Not Taken” - There is always more to discover!

‘All right,’ said the Cat; and this time it vanished quite slowly, beginning with the end of the tail, and ending with the grin, which remained some time after the rest of it had gone.
