.. . I was thinking of drawing programs like Illustrator or CorelDraw...
Re drawing programs ...
I'm using CorelDRAW because I started with it many years ago when it was "king", now Illustrator is generally acknowledged as the industry standard - however Illustrator is way outside my price range.
CorelDRAW is considerably cheaper and the learning curve isn't as steep as Illustrator's, but I suspect that Corel's bitmap program (Corel PHOTO-PAINT) is not as sophisticated as it's competitors, it seems to be mainly a photo editing tool.
Years ago drawing (vector) graphics programs were completely separate from bitmap graphics programs, now the distinction is blurred and bitmaps are the way to go.
My graphics are simple and usually based on line drawings (as opposed to "brush-on-the-paint" style) so I do them in CorelDRAW and export to a bitmap file when I've finished.
All the graphics on my site except for the photos are done in DRAW, even the image of the girl tearing up an L-plate (yes it's a photo, but I cropped it by drawing a precise line round the image and getting DRAW to discard anything outside the line).
I've been wondering how Spinny came by the main graphic on his front page - very cool.
Time-delay shot of a spinning torch?
Or is the secret so arcane that Spinny will have to shoot me after telling me?
