Full Moon

What I like about this picture (Besides the great full moon) is that I got somehow the result that I was looking for.

San Francisco-279.jpg 

The challenge was the following:
 I had no tripod and it was really bright moon.

Having a bright light source might be good but not this time because it was blowing away the craters and the detail on it. it was easily white saturated.  Therefore what I did was to close the aperture to its minimum.  f/38.  And being a far away object I had the focal lenght to its maximum 200mm.

This kind of settings would make a very dark image, or a large exposure time would be needed right? but well,, having no tripod how would I be able to mantain the camera still?

Less focal lenght would give me a smaller moon.
more aperture would overexpose the moon loosing the detail
and a large exposure time would have make a blurry picture ( my hands are not as still as a tripod)

This is the first time that I solve an issue by just boosting the ISO to a high value 3200.
I used the exposure at 1/250 (even if I need to use something like 1/400) because of my focal lenght.

The result was a "dark" picture and with lots of noise, but sharp because of the aperture and exposure time.
What I did was just tweeking it a little bit with the software to gain some brighness on the moon, and filtering the noise due to the high ISO.

The result is shown above.

What do you think? What do you think about digitally enchansing the pictures to solve issues like this?
