A comp focused depth of field plugin has arrived. And hey, it blurs too.

Hi Jeremy,
how does you plugin differ from a standard LW Z-Buffer Layer saved with on of the various buffersavers? The blurring part is clear but how does your buffersaver differ? Spinquad seems to be down so I cant access the thread over there right now.

Hey Limbus,

check the "iDof3 preview" thread. There he talked about the differences. :)

Edit: upps, he didnīt. I guess I need some more sleep, I actually also read it over at spinquad. sorry...

Hiya Florian. I talk about this a bit in the documentation, but here's the further explanation.

Where is the focal point in a normal depth matte? There isn't one defined because the depth matte is not just meant for DOF. It's meant for any number of things (including fog in post, different color correction based on depth, etc.) iDof generates a depth matte more suited to DOF, with areas in front of and behind the focal point going out of focus.

So with a normal depth matte, if your working in Photoshop, Depth of Field Pro, or anything else that batch processes image sequences, you have to pick a single greyscale value as your focal point, and stick with it. No rack focus in post if you're doing that.

Since iDof let's you define and animate the focal point with the black point and white point animation, you can get rack focus even in batch image processors, and still have much faster render times than doing it in 3d.

Does that make sense?

Hi Jeremy,
Posted on spinquad, but though I'd add a post here as its a more recent thread. Just copied and pasted my spinquad post:

Jeremy, this looks very useful to me on a casual glance, but I'm relatively new at this so I wonder if you could answer a few questions:

You say that the plugin doesn't use the focal distance & f-stop from lightwave as they are not that intuitive to use. However, the method I use for controlling the f-stop and focal distance is quite intuitive. I outline my method here http://forums.cgsociety.org/showthread.php?t=330181 post#10. Basically just use channel follewer and nulls to animate these properties. Is the *dynamic* control in iDof this easy? If not, how is it controlled?

Is the iDof a standalone solution to performing DOF in post? I'm doing some animations that require DOF, but it just takes too darn long to render. I'm just at the stage in my learning where I'm really realising the benefits and improvements to quality that can be achieved with a bit of post work :)

Hiya Anti-Distinctly,
The method you use is a good one, and actually quite similiar to earlier versions of iDof. And once you know what f-stop and focal distance are, it's intuitive as well.
The main benefit of using iDof is 2 things. 1.Able to do it in post. 2.you have even more control and easier than with fstop and focal distance, since you don't have to set up channel follower, don't have to do any parenting, and you know exactly what will be in focus, what will not, what the in-focus-range will be, and how quickly the transition from in-focus to out-of-focus will take place.
And if you wanted to parent your black-point object and white point object to the camera (and some do this with idof) and work on the z-channel, that's fine too.
There's a mini-tut that show's in being used with After Effects here:
http://www.spinquad.com/forums/showthread.php?p=123726

iDof is intented to let you take the DOF into the post stage (in After Effects, Photoshop, or another Compositing package). Those packages have blurs included, and you can use the depth matte (as in the link above) to tell the blur where to be.
The post-blur that's included with iDof is really just for those that want the intuitive-ness of iDof with a post blur in LW. If you're happy with your current solution and will be staying mostly within LW, it may not be for you. But there's a trial on the site, so check it out if you want! :thumbsup:
