View Full Version : Getting the miniature effect at RW sizes

05-09-2011, 10:43 AM
I'd like to render that "miniature" or "train-layout" effect, but my scene was constructed at RW scales, and getting the DOF would require some wacky values.

Is there a way to do this that doesn't involve scaling my entire city scene down to table-top size? I'm thinking "enormous lenses", or "enormous film backs".

(IME, depth-buffers in LW are a ridiculous waste of time.)

The thing about LW that a lot of people like is that you don't have to treat settings as if they are based in reality. Go ahead and use a gigantic size film and/or .004 lens F-stop to get the proper effect. Oh I just noticed that I've gone over 1000 posts...yay me.

To know how to getting the inverse effect



helps you to get what you want... at least I hope it

I remember a Photoshop tutorial for creating a miniature look for RW photographs. Too lazy to google it now, but here are the takeaways:

Oversaturate colors.
Really, really strong DOF.

That's all I remember. Maybe pick a long lens?

Heh. Here's one. (http://www.tiltshiftphotography.net/photoshop-tutorial.php) Scroll down to see the effect. Totally convincing.

Crap, I had that backwards! d'oh! 8~ :eek: At least I've managed to remember the f-stop relationship.

Senility is a sad, sad thing kids.

But as clagman above said, in software there's no reason not to crank up the 'film size' to reduce the DOF. --In the real world this would work (if it were possible), and I'm assuming LW takes that into account when it does its DOF calculations.

Trying to do this with Digital Confusion revealed some shortcomings in the code of that routine when used at parameters outside of reasonable values. So, something like a f0.004 gets very funky looking.

Thanks for the links, fellas.

Check it in OpenGL! That will make your life much easier and adjust until it looks right. No need for lengthy renders. Exaggerate the heck out of the Lens F-Stop value.

BTW, in case you need it, the OpenGL DoF preview is in the downpointing arrow after the display type in the viewport. If you already know this, namaste.

I can't follow the links (thanks IT)

But the Tilt Shift photography is what does this. And I believe William Vaughn did a tutorial on how to simulate a Tilt Shift camera.
