To Fill Flash or Not to Fill Flash?

Not that I have a fill flash, just my built in flash. Anyway, here's some pics from our art museum outing and our lunch at Twin Lakes in Eden Park. If I can figure out where the aperature settings and such are stored, I'll post that with the pic.

The first pic, and the next couple pics, are all outside the museum. I think Mango lied to me. She claims that the aperature settings and all that razmajaz is saved with the jpg file somehow, but darned if I can find it.

They both look so thrilled to be sitting still while I tried to figure out how to adjust camera settings. Of course, I only posted one of each pose, in reality, I snapped several pics of each shot....to compare how different settings looked. All of that does me no good now, cause I can't figure out which setting got used for which shot. Next time, I'll make them hold up a white board with the settings written on it for each shot.

Its good to be the Mommy, cause you get to make the rules.

Lunch was at Twin Lakes, which over looks the Ohio River.
Toa of Boy proudly displays his mango. Once with a flash.....

And once without. His face is much more visible with the flash, but does the lighting look unnatural?

Without the face, the details of his face are lost, but the element of natural light directionality is retained.

What do others think? What should I do with these?

And my Sweetling
being contemplative. No flash used here either.

Back inside the museum, where the children finally get to do what they really wanted to....just sit and draw the art.

Again, no flash, because I liked the color of the light and the wood as it was, but I think I went with the absolute wrong camera setting.

 And Toa of Boy.....

I like this one. The natural colors of the wood makes Toa in the foreground really visible. The figures in the background are blurred, since they were walking, but I think that helps to keep the importance on Toa.

Plus, on a non-photography related note, let me state how amazing it is that Toa is SO focused on his work that he remains pretty clear, despite the slow shutter speed. For someone who is a living illustration of Heisenburg's Uncertainty Principle....that is an amazing, rarely duplicated feat.
