The reason the pic is dark is because gamma is saved at value 1.. so if you have it 1.3 or something it will be dark as soon as you take the snapshot
I'm sure this can be avoided but if you do have images like this then open up an image editor such as irfanview or photoshop and use the 'auto adjust colors' feature... which will make them look like this..
Also, Assassin does have a face, I'm sure of it. I think i seen it once while messing around
Are you a real life hoodie?
