Fred showed up when I searched for red, so why not include that too.
I had a lot of success with using blender to very good effect after trying and trying harder to do it. First thing was that I wanted to do a dome, inspired by domes, especially one in Rome which is said to be the oldest building. So having become fascinated with the structure of the dome, and the numbers used for it, (yes, numbers were used to make this building.) I wanted to see if the Sun effect in the room could be had in blender. I made a dome in blender. I made a hole in the dome. I tried to scale it to be the same as the one in Rome (the famous old building that always inspires people).
After so effort at it I was finally able to use the blender time of day add-on (it's there but you must enable it) to make the sunlight shine inside the dome and give a wonderful sunlight at the door of the Pantheon effect on the day and time in question.
Fun fun fun.
here is a tip: you only see the effect if you set up to have shadows and you will only get the effect if you set up with material that will reflect the sun in a way that you would see it.
So if you use a totally reflective material you will not see the sun unless you move to an exact spot. you need to use a difuse matterial, but also one that starts out as a highly reflective one.
as well one needs to setup a proper camera view. and one needs to position the dome with the correct orientation.
all in all once I figure out that the sun position effect was working I realized that I have atool to use that really needs to be shared. It's actually very easy to do it. Yes it's a bit hard to figure out all the settings.
if you use blender and have an interest in sun effects, this add on does a great job! It's tricky to use but worth the time to get it set up.
It's just so cool to say 'well this is late in the day on a solstice'.
Photographers will go on about 'Magic time'. Not magic but the pictures are magical when the sun is right at either the start of the day or the end of it. The long shadows lend themselves to stunning reveals within the images. Often the sun will hit places where it doesn't hit at other times.
in blender you also need to tweek the background sky elumination or it will result in the picture being either too dark or too light, or without a sky. But a nightshift effect with only local lighting will not happen unless you shut off or use a very dark sky. I haven't got that far. In the nightshift meme it's midnight.
