How multimedia is multimedia and what's that got to do with me? Don't knock it till you've rocked it! So to be able to brain-wash myself, that is view and review my own sketches, I scanned them all onto my hard drive. Then I can flick open a picture viewer and look away. I have several viewers the best one is Google's Picasa. Picasa is cool, has many features including a slide show. Oh what good is that? Sometimes while reviewing I see new ideas or how to use an old idea in a new context. Don't study them closely, sort of glance at them in passing, the brain is funny in how it operates, periphery vision (out the corner of the eye) really gets in the brain.
I also have a program that will put your slide show onto a video CD or DVD. You can construct quite a production with transitions styles and a sound track (narration anyone?) This good for a video portfolio or a gallery video art display.
Multimedia is also when I combine my inkjet printing with some hand painted or drawn stuff. Now when you do off computer work you can photograph it too and enhance it on your computer. This will also entice you to use a real pen/pencil or pick up a brush once in a while. By criss-crossing medias new surprises are sure to be noticed.
Play is the thing, serious play because each media has its quirks and character. I can do an ink smear digitally but also on say a paper plate or canvas by hand, they each have their character. As for quirks, pen ink may make a bold line then as it soaks into the surface it might bleed. So here a surface treatment is in order, like a sealant or acrylic gesso. This seals the surface and allows the ink to dry on the surface. In my play I discovered that acrylic paint on the paper plate surface does not bleed like ink does. I can thin the paint with water or gesso to get it to move the way I want.
I do the same play with my printer because photo paper, matte or glossy handles print differently. I also can load various kinds of paper or card stock into the printer. Since the printer ink remains constant, the kind of paper I use really effects the outcome. There is usually a combination that strikes your fancy. To tell you a secret, a lot of simple repetitive operations goes a long way. But, I can't say what works for you.
The main thing is the thought process to get the job done. Don't forget some folks are more inspirational than mechanical. There is a part of art that can't be taught. Even if the technique is good, if the heart or soul is not infused into the effort, it's just a well done mechanical effort. This is why many well trained artist have to get away, lose the training, bury the training, forget the training, exhaust the training, to get back to the core motivations of their artistic energies. Like when you first started, only now you got all this muscle memory and materials knowledge and an exercised vision at your disposal. BUT you all know how it is, you work at it until it flows and it gets better in time. Every stroke is a milestone. And if I'm talking a load of crap, it's because you've discovered a different insight, bravo, work wid it.
