Global Corrections

Levels, Curves, and Color Balance

Local Corrections

Layer masks, clipping masks, dodge, burn

Quick mask

Very exact; you paint the areas you want selected

Quick selection

detects changes in tone and creates selection based on this

Magic wand

More exact; But selects by tone of siliar pixels

working with layers (why, how, how to edit)

important to not destruct the original image and to keep everything oranized

clipping masks

a layer or adjustment that is applied only to the layer below it (uses alt)

layer masks

blends layers. good for seamless images

blending mode and what they do in general

they detemine how the layer will react with the underlying layers based on the type of blending mode

PSD

photoshop file

TIF

tagged image file format: for raster graphic files used to perserve high resolution images

JPG

lossy compressed file; good to make file more compact

scanning formula

input(ppi)= magnifiction output(dpi) OR PPI= mag dpi(300)

scanning formula usage

used ot be able to make image bigger for printing without losing resolution

ISO

sensitivity of image snesor

aperature

how large the lens opening is which correlates to how much light is let into the camera

shutter speed

how long light is let into your camera. measured in fractions of a second

light meter

0 to -3 = underexposed

0= correct exposure

0 to +3 = overexposed

shallow depth of field

smaller f-stop (1.8-5.6) but larger lens opening

wide depth of field

bigger f-stop (11-32) but smaller lens opening

capture movement

a full second or half a second (1/30-2”)

freeze movement

super fast shutter speed (1/2000-1/60)

what is a “stop”

a unit of measurement that describes a doubling (increasing by one stop) or halving (decreasing by one stop) of the amount of light in an exposure.

center-weighted

places emphasis at center

center-weighted average

finds average throughout frae but more empjasos at center

spot

reads light in particlar spot

partial

reads light falling on subject(foreground)

pros and cons of high iso

cons=creates digital noise

pros-lets more light in, lighten images in darker scenery

why CameraRAW

keeps all the data and info of the camera setting or the image and is easier to manipulat and edit later on

angie buckely

uses cutout of images and photogrpahs them in different scenery

sam wang

uses circle illumination in a circular shape to creat unique imagery

david hillard

known for diptychs, tripychs, and panoramic phototgraphs

priya kambli

photogrphs her indian culture and uses lot of colors

thomas jellner

uses contact sheets images to make an overall bigger image

dan estabrook

uses hictoric photogrpahs and drawin to make his iages. knwown for diptychs and grid images

olivo barbieri

makes huge waterfalls and coastlines seem like small models

sean wilkinson

photographs out of focus on purpose to add meaning into his images

cynthia greig

juxtaposes minature objects in fram with actual-sized human users

virgillo ferreira

refrences lack of focus through multiple exposures to create and uncanny feeling plus softens the photo
