I had posted a moon earlier as part of a Sky Watch post. But only added the Gibbous definition in a note. So I repeated it here.
I also posted these new photos because I wanted to tell you how I did it. These photos were shot during late day with a blue sky. The EXIF's are as follows:
1) 300mm,F16, 1/320 sec,the EC is -4.33 step.
2) 300m, F16, 1/250,EC -4.33 step.
I used PS8 and increased the size and lightened the exposure to about 1.80, anymore and the dark sky goes grainy.The colour showing through the black sky in the grain is red, which I don't understand. These adjustments were made to the raw, and then sharpened and lightened in the fine tuning. So effectively I think I turned the sky black with the camera EC. And then was able to lighten the moon only.

Wikipedia also has a good moon explanation and a good chart @ http://en.wikipedia.org/wiki/Lunar_phase I did not cite Wikipedia earlier.
