A suggestion / idea: Nighttime 'colours'

[Pursuivant]

+1.

While it would mostly be eye candy, FoolTrottel's point about human night vision and lack of color vision is spot on.

Ideally, there would be some way for a pilot to "gain" further night vision if he's exposed to relative darkness for 20 or so minutes, as well as some temporary loss of night vision if he's "dazzled" by bright lights (e.g., searchlights, nearby gun flashes, flares or incendiaries).

Excellent request. In low light conditions people see mostly grey. The ground in the edited picture looks good, but I think the sky has more colours at night. More dark blue (of course it depends on the time at night and clouds). Snow can look blue at night.
While speaking of lighting conditions, I think that Il-2's dusk looks very good for such an old game.

I've edited FoolTrottel's pictures. It has the dark blue sky and the grey ground. What do you think of it?

So, grayed out ground and water textures, but dark blue sky to reflect starlight and sunlight from over the horizon.

In moonlight conditions, things get interesting. Functionally, reflected moonlight can be treated as very dim sunlight. In reality, the moon is slightly better at reflecting red wavelengths of sunlight - making it appear red - but because humans lose their ability to clearly detect red colors in low light we perceive moonlight - even bright moonlight - as being more neutral.

Pretty good.

I'm not sure how well IL2 can handle lighting effects, though, given the age of the graphics engine. Ideally, everything would be handled with formulas that handle things like luminosity and light scattering at a distance.

Thank guys for your insights...!

To keep things as 'simple' as possible, me thinks just tuning down all colours towards grey-ish - both sky and ground all together- would suffice here...

I would imagine (to to it properly) you will need separate map textures created for TOD
perhaps 5 classes sunrise midday evening dusk and night to make it "realistic" but that's a big ask.

Or

The mission map loading TOD reference triggers a colour to black and white gammut so the game drops the global colour reference internally.
auto switching the video setting in IL2 and not using the ATI Nvidia software to control it.

Quite a bit of work, but you could just turn the monitor colour down locally to suit your eye,
as you can imagine there will be as usual people complaining about its too grey or not grey enough etc etc

Actually, it is done that way already. When you got 32 bit enabled, the last 8 are used for lights. You could see this by generating TGA files, and opening them with a picture editor that support multi layered images. A screen shot at night will look full daylight just by removing this last layer.

Problem is that colors are being darkened, but not turned into B/W.

It could be achieved by establishing a threshold on the darkening layer. When lights go below X, all colour levels are equalized, achieving a true night sight.

How are you generating the tga file ?
