I like to give my clients and colleagues as much technical information about what I do as possible.
I use Adobe’s Creative Cloud software to draw images and graphics, form print layouts and create web sites. Adobe Creative Cloud is the most widely used design software worldwide, by some distance.
I sometimes use other software for more highly-specified design but I can always supply you with work that printers and others will be able to work from easily.
However, nothing beats pencil, paper and imagination for realising ideas!
