Now allow me to digress and talk about the depth
of field and anamorphic lenses. for me the way the

light gets distorted and scattered while passing
through our virtual lens is an integral part of

the whole lighting setup and it's definitely an
important part of our cinematography, so let's

get into the camera settings while having the
camera selected and activate the depth of field.

right away we can see that our camera focused
on a certain point and we can shift this point

with the help of the distance slider, it works
just like the focus ring on the lens, it works

in a really physically plausible way, because
that's a path tracing render engine and to not

guess the distance, it's always easier to have
a focus object somewhere in the scene like this

empty object here, the easy way to place one is
to Shift and right click to place a 3D cursor

somewhere, then Shift A and spawn an empty object,
but I'll get rid of it because we already have one,

let's use it. it's called focus... so I'm clicking
on the camera border to select it, then down

within the depth of field settings I'm clicking
on the eyedropper and selecting our Focus empty...

as for the lens aperture settings we have the
f-stop parameter that controls how closed or

open is our aperture, the higher values produce the
extended depth of field, very wide depth of field

and on the contrary the lower values like 2.8 or
even lower like 1.4 produce a very narrow depth of

field, where a tiny portion of 3D depth is in focus
and everything else is devoured by a creamy bokeh.

we can fine tune the bokeh shape by
adjusting the number of the aperture blades,

we will see the effect in just a moment and
also adjusting the anamorphic ratio, where

one is a perfectly spherical lens and
two is a lens within anamorphic squeeze.

I'm gonna go with 1.6 for balanced, slightly
anamorphic look. the way that the anamorphic

lenses work aside from squeezing the out of focus
elements is that it leads to a widescreen aspect

ratio like 2.5 to 1, like 1920 by 816 pixels...
let's run a quick comparison now, here is a

perfectly spherical lens with the aperture ratio
of 0 and the 8 blade aperture. here we've bumped

the aperture ratio to 2 meaning an anamorphic
lens. it still got a retro 8 blades aperture look.

if it's an anamorphic lens it should probably
have a widescreen aspect ratio, you know, to keep

it historically accurate :) and this pairing of the
lens and the aspect ratio just looks *cinematic*. and

finally it should probably feature an anamorphic
flare, but we won't go that direction yet.
