like, the projector is probably still set to the same level of brightness of the bulb that's projecting, whether it's 24 fps or 48, but what's happening is that your eye can see more visual information than what it sees at 24 fps, so there's these gaps...imagine it almost like a series of images with black spaces in between that flow together so quickly you don't know there's black spaces, you just see the motion picture image. but the image is "darker" to your perception than a real-life image would be because you are actually getting less visual information, but you're getting enough that your eyes and brain smooth out the gaps. the "brightness" of the picture wasn't ever really an issue in 2D but suddenly with 3D we're putting shades on in a darkened room and your eyes start straining a lot more. with 48 fps you are given more visual information and so, in a sense, there are less black spaces in the moving image...thus it can seem "brighter," in addition to the reduction in strobing, flickering, blur, etc.
