That has worked well for you. It's a great shot.![]()
I do think some other character spots have much harsher lighting though. I could be wrong, but I'm thinking the character spot at Epcot might have even have some exterior windows. It's been a while for us though for that spot, so I could totally be wrong. My least favorite spot is 1900 Park Fare, Town Square Theater princess meet and Pete's Silly Sideshow. But the all-time worst character lighting award ever goes to the Tremaine family meet and greet at MVMCP last year. They were outside, after dark, against the new castle wall...... without a single bit of lighting in addition to the ambient light from the rest of Fantasyland.
I still prefer to use my flash for my character shots. However, I almost never use it at full strength, for the very reason you cited.
Yes, I was looking through my album and realized that for my most recent trip, most of my character shots were outdoors. And yes, character spot has big windows bringing in natural light.
I agree that the other locations you mentioned are much more challenging. And an external flash can be helpful. So it depends on your priority -- to me, you can still get away without any flash. And I wouldn't want to lug around an external flash for 2 or 3 pictures where it might be useful in the day. But, otoh, if you really want to capture the best possible shot with Mickey at the Town Square theater, then maybe carrying a flash is worthwhile.
As to outdoor fill flashes -- for those purposes, I'm actually ok with the pop up flash.
