How to brighten a photo

What is the difference between these buttons:

I took some pictures in the snow and I want to brighten them up. No matter which controller I increase, the picture gets lighter.
For those who don't understand german: "Helligkeit" means "brightness", "Belichtung" means "exposure"
Thank you!

Ich habe einige Fotos in einer Schneelandschaft gemacht und möchte sie aufhellen. In der deutschen Version von XnView MP finde ich den Button "Helligkeit/Kontrast/Gamma/Farbbalance". Egal, welchen der vier farbig markierten Regler ich erhöhe, das Bild wird heller. Meine Frage: Gibt es charakteristische Unterschiede zwischen den Reglern? Welcher ist für das Aufhellen zu empfehlen?
Vielen Dank!

Welcome to the forum, Tobby.

Could you upload a sample picture?

XnView and Photoshop use the same terminology:
  • Brightness (Helligkeit) | Contrast (Kontrast) | Gamma (Gamma-Korrektur)
  • Hue (Farbton) | Lightness (Helligkeit) | Saturation (Sättigung)
Both “brightness“ and “lightness” are translated as “Helligkeit”.

According to Wikipedia, …
… brightness stands for “absolute Helligkeit”, while lightness means “relative Helligkeit”.
