Grainy Feathers

I think the shot of the feathers look to unprofessional for my video. There are many thing wrong with it, including the unfixable colour, the graininess and the fact it's far to dark. So I am planning to re-shoot this footage on either 27/10/2013 or the 29/10/2013 as the weather is supposed to be clear, therefore with any hop I might even get some shots of stars as well. I prevent the graininess and to attempt to keep the colour more true I will have to change some of the options on the camera. These options include changing the ISO this alters how much light is let into the camera. 

I have circled the ISO grade line.

When I first tried to change the colour on the shot of the Feathers I used colour balance, however the original shot was so bad, there was nothing I could do to it.

I have circled the colour balance options.
