That's quite correct - a typical "RedOx" reaction.

But if you look at what you wrote again, you'll see that you wrote "The more light hit the film the more Aghal exposed an therefore less of those AgHal can be reduced when developing the film!"

And that's the wrong way around. The more light, the more silver halide will be reduced to silver. And the more silver you get in the developed emulsion, the darker it is (within limits).

You are not removing unexposed silver until the fixing, which dissolves the undeveloped silver halides.

Now I got you so where is that hat?
