Hey all!
First up, great image! Thanks.
Second up, I'm confused... I understand (more or less
![Smile :-)](./images/smilies/icon_smile.gif)
the general idea of how the photos are superimposed, but at first glance, the resulting image looks odd to me because when the moon is higher (further from dawn) it looks brighter, but when it is lower (near dawn) it looks darker. Now, I think it get it: I guess its because while the sky is still dark before dawn, the moon appears brighter, and that's how it looks in the image. But why is it that near dawn, not only does the moon appear less distinct, the clouds around the horizon also appear dark. i.e. There seems to be a conflict: When the moon is up high it should seem bright (and it does) but the sky should be dark (its not). By contrast, at dawn, the moon should be less distinct (it is) but only because its being viewed against a brighter sky (but in the image the horizon is dark).
Ok, that's a long way of saying I'm confused
All explanations most welcome!
Thanks,
Tim.
