adobe photoshopdigital image making
the basics
Adobe PhotoShop is an image-editing program that lets you create and edit digital images.
◦PhotoShop is part of the Adobe Creative Suite (which also has Illustrator, InDesign, Flash and Dreamweaver)
document setup
File > New◦Width and height:
Creates the canvas size of your image
◦Resolution:◦300 pixels/inch (dpi) for
print◦72 pixels/inch (dpi) for
screen
◦Presets: have common paper and photo sizes
Orientation:◦Portrait
◦Landscape
the basics
Digital images are made up of pixels.◦ pixels: represent different shades or colors to make up an
image
Resolution: measurements that describe the digital quality of something◦ Image Resolution: determined by the number of pixels per
inch (ppi or dpi) that are printed on a page high resolution images show greater detail and more subtle color
transitions the higher the number the better the quality
◦ Device resolution: measured by the highest capacity resolution the device can output (cameras, printers, monitors)
Good explanation here:

file types
bitmap versus vector
bitmap: type of file created out of pixels on a grid◦ aka raster ◦ resolution dependent◦ photo files are usually bitmap◦ jpeg, psd, bmp, gif, tiff, pcx, png
vector: type of file that created from equations◦ able to scale a vector without losing quality (becoming
pixelated)◦ ai, eps, pdf

importing images
File > Place◦Layer > Rasterize > Smart Object
(allows you to edit layer after placing it)
or
File > Open; Select All > Move
transforming images
transform: change the shape, size, perspective, or rotation of an object
◦ Command T
or
◦ Edit > Free Transform
or
◦ Edit > Transform > one of transform options
ALWAYS HOLD SHIFT WHEN SCALING, ETC. TO KEEP IMAGE IN PERSPECTIVE!
layers
layer: a section within an image on which objects can be stored
◦advantage: individual effects can be isolated and manipulated without affecting the rest of the image
◦disadvantage: layers can increase the size of your file
Remember: the order of your layers in the layer panel determines the order of your layers on the canvas
selections
- selection tools• rectangular marquee
tool
• elliptical marquee tool
• single row and column marquee tool
• crop tool
• magic wand tool
• lasso tool
• polygonal lasso tool
• eraser tool
• background eraser tool
• magic eraser tool
selection: an area in an image that is surrounded by a selection marquee.
marquee: dashed line that surrounds the area you want to edit or move to another image
editing images
opacity: determines the percentage of transparency
◦100% opacity will obstruct layers beneath it
◦1% opacity will appear nearly transparent
working with type
type: design world’s name for text◦ measured in points (pt)◦ 1 inch equivalent to about 72 points
Remember: each time you add type, it will create a new layer
font: characters with a similar appearance◦ serif: characters have a tail/stroke◦ sans serif: characters do not have tails; usually used in
headlines, etc.
Window > Character, Window > Paragraph: The character and paragraph panels will show options for type.
working with type
type spacing: adjustments you can make to the space between characters and between lines of type
kerning: controlling the amount of space between two characters
tracking: the insertion of a uniform amount of space between characters
leading: amount of vertical space between lines of type
saving files
Always save as you work!
Always have a version of your file in the original software (PhotoShop> .psd).
flattening: merges all visible layers into a single Background layer and discards all hidden◦ good idea to save an original, unflattened version of your file
because you CANNOT unflatten once you save
◦ flatten command located in layers panel
Format for saving files:◦ lastname_firstname_projecttitle
◦ example: tieriton_kathleen_selfportrait
