And can it be done in Bryce 4? Can someone show an example?

This is an example done in Bryce 5. Depth of field is basically using your virtual camera like a real one and focusing in on a particular part of an image, causing the rest of the image to blur. To the best of my knowledge, it can't be done purely in Bryce 4; you need an image editor like Photoshop to add the blur. The way I always did it was to render the image, then select the object I wanted to focus on and do a mask render. Then, in Photoshop, load that mask and apply a gaussian blur to the rest of the image. I'm sure others can illustrate and explain it better than I. But take my word for it: I like it a lot better in Bryce 5, and even though I tend to overuse it right now (because it's so dang COOL), I'd have to say that even normal usage of the feature makes it worth upgrading to B5 for me.

You explained that very well. I was wondering, too, if it had to do with perspective. I notice in Terragen projects, that those landscapes generally have a great deal of depth to them. I find it difficult to get that same feeling in Bryce, yet I have seen it done.

nice ajtooley! a fellow texan too! Jared

Thanks, rockjockjared. However, I'm Montana born and bred. It was just a silly image in my head for a possible challenge if I ever should win the chance to dictate the subject: visual puns. As an example, I created the --snicker-- "Texas Panhandle." But I've been to Texas! Does that count?
