camera focus impossible ?

[Jean-Paul Paloux_cg]

Hi,
is it possible that I can't focus on something ?

I have a scene in mm.
my camera is with a 34 angle.
I Zoom and place the camera the way I want.
then I right click and set "Show Camera"
Then I trace a line between camera point and the place I want a perfect focus.
I say Analyse Lenght, it gives me 6.634mm
I write it in the camera center bias.
I put an aperture of 0.1 because I don't want a lot of blur after and before.

But even if I put the correct distance, it is still blurred and it's clearer further.
why ?

It is supposed to work this way...
but it seems like there is a minimum range before being able to get a focus like in a real camera. Am I right ?

I should then pull back the camera, get a bigger scene, but croped the render picture. OR pull back the camera, but do a "render window"

The problem is that I set a lenght width matching with my camera windows, don't want to change at all the setup of camera target etc

Jp

center bias ... special option of bokeh effects ... see at user tutorials D

If you like to manual set the focus distance, than use the option "override focal dist.". But much better, you use the focus scripts. You will love it.

The script makes: you press a button and you click (osnap enable) at a point in your scene. Ready, this point will be focused. You must like it!

Sleep ... what is it? No, now the weekend project is finished, time to relax.

The focus script sounds perfect for what I want to do - but to my embarrassment I've never used a script in Rhino ( ) . Any chance you could let me know who to use it?? cheers

Micha - It works like a dream
Just one question: why would you need to use the 'show target plane'? Do you have an example of how (or why) it's used? Cheers again

Last I rendered a ring with "diamonds". I can not show the image here. It was very difficult for me to see which parts of the ring are focused and which not. The trick is, if you set the viewport at "rendered" mode, than you can see, that the plane is halftranparent. So, it is possible to see, where the focus plane cut the scene, what is behind and what in front.
