The graphic- and computer designs or webpage editing is not my profession. My opinion is, if you want to work in the civil-, culture- or artist areas you need this average knowledge.
Of course I do the graphic designs, most of the photos (my Muczkó help me sometimes) and the editing in my own webpages. But it was part of my jobs, when I worked for foundations or I managed culture projects as well.
In the past, when the internet isn’t gobbled up everything, I designs posters and flyers. Nowday the banner design or website creation for events are more common.
I creat T-shirt patterns or home-designs or whatever is needed, mostly for presents to my loved ones, just for fun.
