Raster vs Vector

Last lesson we learnt about raster and vector images, along with the key differences of both. I also found a blog that illustrated what we had learnt, to visit this blog click here

Raster

• Photoshop uses raster images
• Resolution dependant
• Uses DPI ( dots per inch) and PPI ( pixels per inch)
• When scaled up the pixels get larger and the image becomes less clear

Vector

• Resolution independent
• Illustrator uses vector images
• Scaled down or up without distortion
• Uses mathematical formula and no pixels
