hey I'm trying to figure this thing out once and for all

how would I match a real-world camera to Houdini? the focal length is easy

the aperture is what I understand is the horizontal sensor size /2... or something

if that's so how would I get the vertical?


for all-purpose, Alexa35 is 27.99 x 19.22 sensor size, the sensor aspect ratio of 16:11,
how do I match that?

thank you in advance.

Unless you're doing anamorphic rendering, you can ignore the sensor height, as it will be based on the resolution aspect ratio and width. For houdini camera objects (not solaris) there is no sensor height parameter, just resolution and width. For solaris, the sensor height can be defined manually, but is based on the aspect ratio and width by default.

o ok thanks so just the width and resolution ill try and match that
