To my mind, the first is just way too dark.
My screen is bright.
To be thinking I would still be using my old screen --- most parts at the bottom would be all black!
The second is better, exposurewise, though I personally don't like the clear division into two halves so much, with nothing on the right. Now if this photo were one to bear the big letters of some advertising -- but maybe it IS designed to also sport some letters on the right?
