How Do I Know Which Artistic Medium To Use?

OK, so I've got my idea. How do I let everyone else see it? This is probably the hardest question to answer, and the more skills you learn harder still. Short answer - depends.

It depends on whether you are under a deadline, and if so, how tight a deadline. Will it be printed, and if so, what is the printer's requirements? If it is digital, what resolution is necessary, and will a higher resolution possibly be asked for later? Etc. Etc. Etc.

If you are under a tight deadline, of course a more time consuming medium is out of the question. If the final is to be a digital file, maybe you shouldn't paint on canvas and have to foot the time and expense of scanning. If you are designing icons for an OS interface, perhaps you shouldn't make the original file at 4 feet by 4 feet at 300 dpi - that's just going to slow you down.

So, asking a few questions will speed things up:
1. What will the artwork be used for? Multiple uses?
2. How long do I have to deliver?
3. What format does the client need it in?
4. Can I give my client exactly what they want in a faster, cheaper manner?

I hope this helps you answer a question that doesn't really have to be a difficult one. And always try to keep expanding your arsenal of capabilities. Your clients will keep coming back if they feel confident in your versatility and flexibilty.
