Some of you studio people might find this useful. I came across it on a thread on DPReview. Various studio set-ups can be shown using the layers in PS. Seems very handy. Here is the direct quote from DP and the link to the file.
It a Adobe Photoshop Document file developed by Kevin Kertz. After you unzip it and open it in PhotoShop, you will find each studio component on a separate layer – none of which are set to visible. Open the layers palette to see them all. http://www.kevinkertz.com/fm/LightingSetup.psd.zip
I downloaded this months ago and still haven’t played around with it :cry: HAving said that, this is the type of thing I’d prefer to do in Visio (although that’s not as universal as Photoshop is I guess).
