Graphics Design
Adobe - Canva
Adobe Photoshop
Photoshop is a raster based software, it works on a pixel based level. Images built using rastor based software can easily become pixelated, but that can be avoided.
Adobe Illustrator
Illustrator is different from Photoshop in that it is a vector based software, meaning instead of working on a pixel level, it works using lines.
Adobe InDesign
InDesign is most commonly used for complex book layouts. What I personally tend to use it for is actually to produce pdf presentations.
Canva.com
Canva is an online design tool that offers users the opportunity to create professional-looking posters, slideshows, images, event flyers, resumes, cards, certificates, infographics, and other media.
