Someone from our local camera club sent me this. I forward this to the Pentax list with great reluctance. I feel like I'm selling crack to kids. Anyway, if you don't want to be a real photographer and use real Velvia and you're willing to settle for some phony baloney digital horsepockey manipulation you might find it useful:
Tom (Shoot Film Dammit!) Reese Attached is a free action designed for use with Adobe Photoshop CS/CS2 that will give your digital images a Velvia touch. http://www.thelightsrightstudio.com/TLRDigitalVelvia.htm For those of you that may not know, actions are an automated set of adjustments in steps that Photoshop applies to a selected photograph. It's Adobe version of the "easy button." I just tried the action and it works great. It has a lot of flexibility and creates a separate layer that doesn't harm the original file. This allows you to adjust the opacity of the saturation to control the effect. The action will also let you select the specific color group that you want to saturate.
