I'm looking to get into designing a nice poster in photoshop (I have 6.0). I don't really know how to get started. I'd like to make something of high quality; someting that looks like the poster competition winners for the conference (well maybe not that good). I know this is flashkit, but if anyone knows of a good tutorial or place to start (I'm not new to photoshop, just new to making professional-looking stuff in it), I'd be much obliged. Thanks.
