I have 2 questions on flash for my upcoming Disney World trip. 1. How do I meter and set the exposure for shots like this? This was taken on our last trip the the Disney PhotoPass folks. How do I set it up to light us well, and still get the Castle? 2. When taking photos of my daughter with the characters many times it is inside in areas not too well lit. On the last trip I did ok capturing those shots but I used the popup flash. So on this trip I want to improve the quality of those shots. Here is an example: In that one I had to crank it up to 800 ISO and use the popup flash. So I'm trying to decide do I carry a full flash with me for those kinds of shots? What would be the best setup for that?
