Description
Wanted to try out a depth of field effect, but with my system causing the program to render so slow it would probably still be going a week from now had I let it continue. I'll try that when I've got a better system.Edit: Changed the image to include the Depth of Field effect I applied in Photoshop.

If you have Photoshop CS4+ and Poser 8+ = you can do the depth of field in photoshop - I do it all the time.

Actually working with CS3 and Pro 2012, but I found a way to pull it off. I was gonna get a newer version of Photoshop, but I scrapped that idea in favor of a newer Poser.

I'm not sure if CS3 can do the "lens blur" or not - you'd have to check. (it might)

I found a way to do it. Looked up a tutorial and it was all stuff I was already familiar with, I just never thought of this for some reason.

yep, that's the process - but if you can output a zdepth channel from Poser - you get a really cool mask to use for the lens blur.

Not even sure how to get a zdepth channel from Poser lol

it's EASY in poser pro 2012 - go into the render settings of your current image. On the right side = under Gamma correction there's a dialog for Auxilary render data - hit the little triangle next to it - then check "Z depth" channel.
next time you render that scene, when you save your image, you'll also get a zdepth image. (unless you output a psd - then it's built into the file) I work with pngs so I always get an extra zdpeth png. There are tricks and tips after that stage, but try it.

Giving it a shot now. I am noticing it's taking a little longer to render, but not as long as using depth of field was causing.

I never noticed a difference in render time to be honest. yep, just did a test - same exact time to render a simple scene. Here's a tip - need a depth map from an already rendered image? EASY - Turn off all of the lights and shadows then render it. (Lighting doesnt affect depth mapping)

And I only just now read the bit about turning lights and shadows off. lol. Image is over halfway done now, so I may as well just wait.

Could just be that I'm sitting here waiting on it, whereas I usually go watch TV while I have a final render going. Maybe I'll get up for a bit lol

if you want to do a good dof without doing it in rendering try using Alien skin for cs5 photoshop it gives good results without having to wait for render time its just a pain to select out the figure.

Actually, when I know I'm going to need to have a specific feature on a separate layer, I simply delete all else from the scene except that which I intend to extract and merge to two .png files into a multi-layer work file. Saves considerable time in selecting an element of an image.

Click on Layer, go down to Matting all the way at the bottom, then click Defringe. Try it in intervals of 1 at a time. Gets rid of the line.

Really like it man! i think it works even without dof. Keep up the amazing work
