Rasters Vs Vectors
In the first Imaging class we contrasted rasters and vectors by teaming up and researching each one’s weaknesses and strengths.
Raster graphics consist of pixels, which are the smallest addressable elements on a screen. Most pictures we see on screen are raster images, such as GIFs, Jpegs, and PNGs. They make up movies, TV shows and photographs. The more detailed an image, the larger the file capacity. The resolution of these images is expressed in terms of the number of pixels in a column times the number of pixels in the row. For instance: 1920 x 1080 px.
Vector Graphics, however, consist of paths and lines, instead, and can be maximised and minimised upto 20% with the quality of the image still in check. They are constructed with mathematical formulae instead of pixels and can be used for graphics that require resizing. Vector graphics are used in PDFs, AIs, and EPS.
Adobe Illustrator Software
In the first imaging session we also learned the very basics of the Adobe Illustrator software. We explored what each tool in the tool bar can depict on the art board. We also learned shortcuts to access the tools. Such as “V” for the Selection tool, “A” for the direct selection tool, “P” for the pen tool, etc.
