Tuning Your Preset

⁠

When it comes to tuning your preset you’ll be mostly working with:

⁠

@Max Distance⁠

⁠

⁠

@Focal Length⁠

⁠

@Base Aperture⁠

⁠

@Extended Aperture⁠

Start with the

@Max Distance⁠

from 0 and bring something in the foreground into focus

⁠

⁠

⁠

Next set your

@Base Aperture⁠

to the overall level of depth you want for your scene

⁠

⁠

⁠

Set your

@Extended Aperture⁠

until most of the core foreground of your scene turns blue.

Internal Vs External Scenes⁠

⁠

Setting your

@Focal Length⁠

( or test your ingame ones if you have multiple)

~17.13 is the common 70 FOV in many standard games like FPS based on a full frame sensor size

Set your

@Base Aperture⁠

to a value you want to use when moving around the scene

For an example if we take 5.6 base and 32 extended we could have a nice natural depth you might be more accustomed to and would be useful when exploring areas where you want a little bit of depth, like an open vista.

Notes

1

2.4

roughly the aperture of an eye in terms of DoF

2

2.8

a lot of shallow depth of field good for object close ups

3

5.6

a common average many lenses and shooting conditions

4

8

a very natural lens setting, gives you a nice balance between slight depth and a sharper scene

5

11

From here an above, a great setting for the extended aperture to be set to for open scenes
