Photoshop Stuff:
Interpolation – This occurs when resample image is checked off in the ‘Image Size’ menu
photoshop takes the photograph and interprets the pixel and adds more pixels, guessing the color of the pixels – NOT GOOD! Pic becomes pixilated
-the best interpolation is bicubic – looks in 4 directions for pixels
-bilinear option is ok, it looks at 2 pixels
-nearest neighbor option -bad! Just looks at the neighboring pixel
-To avoid this, UNCHECK resample image, which makes the image smaller while upping the pixel amount.
-to make a 5x7 print: click the crop tool and enter 5 in the width and 7 in hight and adjust the crop box as you see fit. Press enter if you like it, escape if you don’t.
-Removing red eye – under the crop tool, just click the tool, go on the eye and poof! red eye gone!
Printing Photos:
-Prints should be 300dpi
-Epson is the best photo printer, and most use ink-jet printers, rather than laser.
-Archival Inks & Paper: papers and inks with acidic levels (PH levels) that let the photo last and not fade. Epson gaurentees their prints (with their inks) last 72–100 yrs
-Iris Printer – best archival prints
Documentary photographs:
Mathew Brady – one of the first to shoot documentary photography, he shot images of the Civil War
-During the Depression the USA hired a group of photographers from a faction of the govt called the FSA (Farm Security Administration) to document the depression.
2 of those photographers: Dorothea Lange & Walker Evans
They were required to turn in their negative to the govt. who stores them in the Library of Congress (164,000 negative in total!!)

Photography – 9/21/06
Aperture – determines how much light comes through
It decides how small to make the hole. Shuts down to a certain size hole. Aperture goes from smaller, if bright, to big, if it’s light out.
Depth of field- how much is in focus when take pic. The smaller the hole, the more is in focus. If want a lot in focus- (things close and far) choose to make aperture smaller. (in front of lens)
Shutter - controls motion. Shutter is behind lense. Moves across in amount of time exposure calls for. In dark room takes more shutter time. Bright day shutter speed 1/60 of a second. In darker place shutter could be open for one second until enough light comes in.
ISO = “SPEED” OF FILM
- higher the number-less exposure time – better for Dark (adds noise, looks grainy)
- lower, the longer the exposure – better for Bright
- good to stay around 50 (can go to 100)
-good to go click halfway down on button first – and camera takes all measurements and then when click all the way down, it instantly takes pic.
Resolution = Pixels = dots per inch
-screen only reads max 72dpi (good to keep camera at the highest setting-find where this is in camera manual)
Resolutions - 1)256x256 (cell phone cameras)
2)640x480 – Low
3)1216x912 - 1 megapixel camera (cant even get good 4x6 print from this)
4)1600x1200 - 2 megapixel camera (good 4x6 print)
5)2240x1680 - 4 megapixel camera (good 8x10 print)
Jpg- file format using compression, used by cameras
LIGHTING TECHNIQUES: diff b/w good & bad pics
2 types of light – Natural (sunlight) and Artificial (man-made)
-ppl think best time to take pics is 12noon - Wrong!
-Best to shoot in morn (sunrise) until 10:30am
-For night shots – 2hrs b4 sunset
-these times give golden light and good shadows
Natural Light – 1) Backlighting – sun shining behind subject of photo, this highlights subject’s figure and using flash fills in the details of the person –called “Fill” Flash.
2) Side Lighting – sun shining on side of the photo – giving a dramatic shadow to side of subject. If it’s too much of a shadow, hold a white posterboard on the other side of subject –opp. of sun (called a “Fill” Card) which reflects light back on the person.
3) Diffused Lighting – if shooting at noon, photographer & subject stand in the shade, diffusing the light. OR can use big white umbrella / white screens.
Artificial Light – 1) On Camera Flash – (flash inside camera) causes shadow behind subject, so move subject away from wall (so shadow falls on floor)
2) Off Camera Flash – additional flash (can buy one that screws onto side of camera), tilt the flash up, so its not straight on the subject but rather bounces off the ceiling.
3) Ambient Light – taking pic with existing light in room (no flash used)
Aperture – determines how much light comes through
It decides how small to make the hole. Shuts down to a certain size hole. Aperture goes from smaller, if bright, to big, if it’s light out.
Depth of field- how much is in focus when take pic. The smaller the hole, the more is in focus. If want a lot in focus- (things close and far) choose to make aperture smaller. (in front of lens)

photography class notes
PHOTOGRAPHY CLASS – 9/14/06
TIMELINE:
350BC – Aristotle
1600’s - Camera Obscura
1802 – Thomas Wedgewood
1826 – Niepce
1829 & 1839– Daugere
1833 – Niepce dies
1850 – Archer
1870 – dry plate
1888 – celluloid
1889 – Kodak
350BC – Aristotle looked at an eclipse through a strainer and the image of the sun was projected on the ground
-got ppl curious, and interested in capturing an image the way it ‘was’ rather than just painting
1600’s - Camera Obscura – developed Aristotle’s strainer into a box with glass (called a camera obscura), that would project the scene outside onto the glass, so you could trace it exactly. The painter stood behind the box with cloth over his head (so no light came in).
-they discovered that if you adjusted the glass it would make the scene in focus
-the next thing they came up with was to put mirrors in the box to see the image in different places (guy doesn’t have to stand behind box anymore)
-next they put a lens on the front instead of the mere hole, then they added an adjuster knob for the lens
1700’s – the term photography is used with this camera contraption.
The term comes from 2 Greek words: Photo – light & Graphois - drawing
- Scientists saw that silver nitrate got dark from the sun (they thought it was heat rather then the truth – light)
1802 – Thomas Wedgewood – wanted to capture an image without tracing
-he soaked leather into silver nitrate and put leaves on it and let it sit in the sun and used oils, and tada – an image (of the leaves) appeared on the leather!
-his prob: wasn’t able to ‘fix’ the image, it wasn’t permanent, so he had to show e/t in candlelight b/c the sun would turn his images black
1826 – Niepce – he left metal in sun and treated it with aromatic oils and his image stays! His image was the first photograph ever (of some building in france)
1829 – Daugere and Niepce get together to standardize the process of photography for the general public, but in 1833 Niepce dies.
1839 – Daguarre invents the Daugarreotype - which takes 1 hr to make an exposure. Cons – its one time use and can’t make prints from it or mass produce it.
(ppl. were held in chairs so they wouldn’t move for that hr)
-At the same time – Fox Talbot comes up with a process called Calotype (or Talbotype) which gives a negative to make positives from. He puts paper wet with silver nitrate into the camera obscura which accelerates the time to a 10 min exposure. He uses chemicals to fix the image and can take this image into a darkroom and shine a light through it to create a duplicate.
- Daguarre gets credit for photography; even though Talbot was a little b4 him; some say Talbot’s mom talked him out of going public with his idea and to get a real job instead!!
1850 – Archer – a sculptor who takes Talbot’s process of negatives on paper, and instead puts negative on wet glass.
1870 – Dry plate was invented – dry glass was put into the camera, now they can just take the plates with them instead of the whole lab with all the processing equipment – begg. of true modern photography.
1888 – Celluloid (plastic) – plastic plates are invented (basically what we use today)
-Thomas Edison invents the movie camera at this time (strip of plastic run through a projector) con- always caught on fire…
1889/90 – Kodak – George Eastman modernized the film process, he stopped making plates and just put film on plastic – he made up the name Kodak for his company (no meaning!)
-he came up with the first box cameras for home use and the first film in rolls
-he made a red circle on the camera box (film doesn’t pick up red) and as the film rolled past the red circle a pre-written number popped up so he knew when to stop rolling.
-Kodak corners the market!
-Eastman and Edison worked together on the first motion pictures & cameras.
-Edison was working on a big 70mm film, and asked Eastman to cut it in half for him, creating the 35mm film and camera which became the standard.
-Kodak focuses on the public rather than the professionals.
