Cameras (VRAY), is there a 'standard' setup/rule?

[phoenix4]

Hi Everyone,

Camera setup has always been difficult for me.

As, you can fit the same image, in the same render window, with totally different settings.

HOWEVER, the final results can be quite different.

Is there any rule to follow for:
Target distance, focal length, film gate and zoom factor settings?

Attached are two WIP renders (no need to comment of the character etc..).

lm-c2b
--------
film gate: 36mm
focal length: 483.6mm
zoom factor: 1
target distance 803.79cm

lm-c2
------
film gate: 36mm
focal length: 65mm
zoom factor: 1
target distance 111.87cm

As you can see, both of my renders are the portrait shot I am after, but they are 'distorted' differently.

What is the rule for un-distorted, 'real life' settings?



Thanks,
Adam

Vray physical Camera is set up to match real-world camera settings, lens types, etc,etc so the best thing to do is to look at what type of lens/settings a real photographer would use for portraits, & try to match that.
Portrait lens are usually macro or zoom lenses so that you can achive a very small focal zone [DOF] where they eyes are sharp but the rest of the face gets a soft blur & the background a heavy blur.


Hope this helps
