Hidden Brightness/Darkness setting and how to fix?

[Snikersnee]

A while back, while playing on my laptop, I pressed a button associated with gameplay which made the game progressively darker and darker, up to a point. The game was not horribly dark, more atmospheric, even, but even after moving the files from my laptop to my desktop, the darkness persists. It is not a nuisance, but I would still like it reverted, the only problem being that I can not for the life of me remember how it happened - even at the time I was confused.
I can tell that its not my monitor or other external issue, because whenever I load a save, for a couple frames the original brightness level exists, before going darker again. I cannot get screenshots of the non-darkened game because the game is (presumably) still loading during this time, but here are some screenshots of the game post-darkening.

I don't know if this is a dosbox or a Tombraider problem, but I would appreciate if someone could provide a solution - preferably one that doesn't involve file editing, as I am not a software-minded person, and the only editing I have done to the game is editing the keybindings in dosbox itself to allow for a better playing experience, such as making wasd the movement keys. I have found nothing about this issue online, so this is my last hope for reverting the game to its previous state. Granted, I could just backup the saves and dosbox remapping config and just redownload the game, but this issue is a puzzle to me that I'd like to solve. Any help is appreciated.

Powerstrip is your friend. :)

It allows you to increase/decrease gamma in-game by using hotkeys. I use it for several Tomb Raider games.

IIRC the default hotkeys are;

alt-ctrl-Numpad+ = increase
alt-ctrl-numpad- = decrease

If you right-click the tray icon after playing there is an option to reset to default (so that your regular brightness is restored).

I mainly use it because TR1 is too bright for me, having grown up with the darker console version. And TR:Chronicles is too dark. But trust me, Powerstrip works great!


Oh and also, for the love of god stop using the horrible dosbox version. Use TombATI, or the automated patch instead.

Actually this patch will probably fix your problem without even needing powerstrip... Just as long as you can tolerate the PC version being overly bright. (But that's just my opinion. Many people seem to be fine with it's brightness).

Well, downloading TombATI fixed the problem, whatever the problem was. Plus, it has many other great features so I consider the problem resolved.
