How do I can change the brightness in the game?

It's to bright for my monitor. As I remember in Follout 3 /NV it was possible.

Thank you in advance for kind reply.

You don't, there is no gamma slider. Either Bethesda are that half assed or they don't even trust us to set the gamma correctly.

There needs to be a slider. I made an adjustment on my monitor. But I shouldn't have too.

May I correct it inside of .ini files?

After 2 hours of the game I'm afraid I'll be blind tomorrow.

Developers, please made sliders of the brightness and gamma.

Yes please, what were they thinking?

Plus also maybe add a slider that apart from pipboy hud color from the light color.

I did not find the game to be overly bright although it could be toned down a bit. Have you tried calibrating your monitor? Most monitors out of the box and or in gaming mode are way to bright. Use one of these images and adjust the gamma and contrast and or black levels so the screen is almost too dark to show all the details. Your aiming for about 50% brightness and about 80% contrast, although your settings will vary somewhat in your room and lighting
