Review Digital image: made up of dots called pixels

Use Photoshop to add, modify, or delete individual pixels or groups of pixels

Image Resolution

Spacing of pixels in an image, measured in ppi (pixels per inch) or dpi (dots per inch)

Image Size

Physical dimensions of an image, measured in pixels (width x height)


Review Most Photoshop images are composite:

Multiple images or visual elements from

different sources combined into one

Images can be saved in various file formats

Default file format is .psd

Photoshop’s native raw format, similar to .tiff

Preserves layers

Typical image formats: .jpg, .gif, .png

Flattened image
