Apertute from distance
Hey guys …
thanks Dan for that great autofocus expression. What would I need to type in to link the aperture to object distance? let´s say the camera is quite far away from an object, so I would need to raise aperture levels to blur out the image. but when I track the camera closer, I need a lower value for aperture, so that I don´t blur my bg to hell.
thanks a lot for all your help
Christian

Seems like you cold tie aperture to focus distance with an expression like this:
focusDist = cameraOption.focusDistance;
minAp = 20; //minimum aperture
maxAp = 200; //maximum aperture
fMinAp = 1000; //focus distance for min aperture
fMaxAp = 100; //focus distance for max aperture
linear(focusDist,fMaxAp,fMinAp,maxAp,minAp)Dan
