You should definitely get one of these:
A Hoodman Hood Loupe. With it, you can see your LCD even in bright outdoors daylight. It adjusts to your eyes and it magnifies, as well. Invaluable, and I would not go anywhere without mine.
I am so glad I had mine in Arizona last week. Otherwise I would not have seen what I was getting in bright “creative light” like this:
Without a Hood Loupe, you are guessing. A sin “I think they’re OK, and when I get indoors I’ll see for sure” – if you can even see the display at all.
