In case you are not familiar with the term, vector drawing involves the use of mathmatically defined lines and shapes to create artwork.
By themselves, vector images limit detail and texture in the interests of line and sharpness. In their native state computer drawn images can be scaled to any size without having to worry about resolution.
I often begin with simple ink drawings on paper. The drawing is scanned and run through an operation that transforms lines into vector shapes. Of course, you can always begin with drawing on the computer but somehow that often feels less organic. Texture is added later.
I worked for many years with Adobe Illustrator but Adobe's ever increasing subscription pricing as forced me to abandon it. I now use Affinity's vector capabilities, which have been very useful, although I am still trying to adjust to them.
Several of the images on this page are the result of messing around with Affinity's vector drawing. I am still very new to the software.
