Description
Once you’ve sent me your hand-drawn (or raster) image, then I’ll convert it into a vector image using Adobe Illustrator. There are two types of images:
Rastor:
- file extensions: png, gif, jpg, bmp
- saves the red, blue & green values for each colour of each pixel. These images can be compressed when neighbouring pixels are the same or a similar colour.
- Think of the famous dot painting from 1884 “A Sunday on La Grande Jatte”.
- Resolution refers to the number of pixels (or dots) used to describe a square inch. This is known as Dots Per Inch (DPI), eg: 300dpi
- Resizing involves resamping the image. That means pretty much guessing what each pixel would be at a higher resolution and never turns out like you’d hope.
- jpg is best for photos – the smaller the resolution, or the higher the compression, the more jpeg artifacts your photo will have. It’s where the colours blur.
- png & gif are ok for logos
Vector:
- file extensions: svg, ai
- saves the x,y coordinates as well as mathematical equations to redraw the lines and fill coloured areas.
- Should not be be used for photos
- Great for logos
- Can be resized extremely easily and keeps its sharpness and clarity without losing any quality.
