Microscopic effect shader

Hello guys, i hope you´re ok.

i´d like to get a microscopic effect shader for my objects, like the following images:

I was reading that using rim lighting, i´d get something like that, but what do you think?
I´d like to hear suggestions, because i´m newbie in Unity and maybe some of you already got the microscopic effect.

Thanks
Luis

The spheres on the top screen indeed look like they have a rim lighting effect. But not all these images really show that as much.
The recurring theme here is a shallow depth of field. Parts of the image that are far away or extremely close appear to be blurred. In real world photography, a technique called ‘tilt-shift’ (referring to the tilting and shifting of the lens relative to the sensor or film) is used to create this effect on large scenes, making it look like a miniature.

You could experiment with these standard image effects:
Depth of Field
Tilt Shift (This doesn’t actually shift exactly like a real lens would, but it does create the blurry effect)
Depth of Field 3.4 (older)

I have a feeling that for the surface materials, you could get decent results using the matcap shader.
