Jarv's Pymol Horrors
set orthoscopic, on - no silly perspective distortions
set spec_reflect, 0.0 - turn off specular reflections (shiny ness), makes a very nice flat colour aesthetic for spheres
set light_count, 0 - set number of directed lights to zero, therefore no shadows (also speeds ray trace)
set ambient 0.6 ; set direct 0.4 - play with mix of ambient and direct light. Fully ambient and your spheres are glowing and you can't see the edges
show spheres - the way to solid state joy; show vdW spheres for your atoms
A good starting point for ray tracing:
set ray_orthoscopic, on # no silly perspective
set ray_trace_fog, 0 # off
set ambient, 1
set reflect, 0
set specular, off # dull balls
bg_color white
set antialias, 2
set ray_shadows, off
viewport 1920,1080
color grey, (name N*)
set transparency, 0.2, (name N*)
show spheres, (name Cs) - put a nice big vdW sphere on the Cs ions
odd form for stick_transparency (i.e. what we're always doing for organic electronics)
set_bond stick_transparency, 0.2, (name N*)
set antialias, 2 - maximum anti-alias for ray tracing
bg_color white - white background for publication; requires anti-alias + ray trace to avoid jaggies
ray 2048, 1524 ; save raytrace.png - large poster / slide friendly ray trace & immediately save, to avoid risking disrupting Pymol with an inconsiderate mouse move while it's raytracing

Set pymol to correct aspect ratio for widescreen with 'viewport 1280,720'
- 2160p: 3840x2160
- 1440p: 2560x1440
- 1080p: 1920x1080
- 720p: 1280x720
Fiddle with your settings & make a movie, check scenes individually with 'ray' before setting 'ray trace frames', then save as PNG.
