Colour enhanced moon

Not sure how this stacks up, and whether the colours are representative.

I assume that mineral deposits are the source of different wavelengths, and the colours, though not exact, are not just a light and shade representation.

Added a second image - removed the reddish tones.

Great contrast!
Not sure if you have the white-balance correct so this can give you false colours. If you have a general camera then it maybe difficult to get the right whitebalance. With a DSLR then save images as RAW and then you can modify the white-balance. I usually use 4300K WB but I am still fine tuning the results.

Hi Malcolm, thanks. I have the camera (1000D) white balance set to daylight, taking RAW images. I did adjust WB during processing, but I'm not sure that it's correct.
Basically, I set it to remove any over exposed areas, but didn't pay much attention to the temperature. I processed the image using HDR.

EDIT: Followed your advice re temperature - and set green and hsv manually?

My shot turn out close to your latest one, but i am still yet to determin whether 4300K is correct for the moon, I haven't been able to find any reference to it and not sure how to measure it yet.

I must admit I am not sure what the colours mean but I also think they mean sometihing as well. I also have done some negative images of a normal shot as well which has shown some strange creamy colouring of some craters. I sort of wondering this as well.

(Edit) just a thought could be a heating effect of the exposed moon to the sun that could give these colour.

Colours in the last image look about right to me.:thumbsup:

There is a way to do a custom white balance, but I haven't tried it yet.

I noticed when playing around with the RAW settings that the temperature set by the camera was around 4200. Basically, I told the program to ignore the camera settings.

A bit more reading and research should answer these questions. Thanks for your input, every little bit helps.

Thanks Michael. Wasn't sure, but it looks more natural - now to get the region along the terminator illuminated!

So far I have been looking at WB just to look like something i would see through and eyepiece. That is about as close as i get it. I just invested in a new double polarizing filter which I have insert in between my Baader Plantarium lens. It allows me to change the intensity without removing the eyepiece. I hope if the weather clear try to get some idea of natural viewing colours to help me determin the correct white-balance and contrast.

Apart from that the shot looks good now

Hi Malcolm. I'd be interested in seeing the results.
