Maybe I'm just mad but.... has anyone noticed the following. I'll watch a movie in a dark room and the picture looks great. Then after I bring the room lights up to 50% on the dimmer so the wife can find her way out to make a coffee Now the picture looks eeuuww, blacks are greys and colours are bleached. However as I sit there watching the usual sky inter-movie adverts its like I adjust to the ambient light and the picture starts to look a little better, ie blacker blacks and richer colours. Is this a trick of the mind or maybe some kind of iris effect in my eyes, OR am I nuts? Thoughts.
