Problem: very bright full moon with hazy aura. 100/2.8 macro lens. I could see the definition of the moon through the viewfinder, but I could not for the life of me capture it. I tried a range of exposures, a range of apertures, and center-weighted metering. They all turned out similar to this one. Do I need a neutral density filter? Is the moon too bright?

Fish,

Maybe you can help, there is no image showing up on your posts. I have noticed this on other threads that some of the photos are present, the others just say the image is attached?!?

Is that the moon?

Still over exposed. Which ISO were you using?

I applied a .3 gamma to the 2nd one and got:

Fish - What is the moon but a sun lit object - that is to say - the moon basically needs the same exposure as a sunlit scene on Earth - and your camera meter gets confused with all the black arund the moon.
Good exposure estimate is 1/ISO at f16 for a sunlit seen - hence at ISO 100 you should need 1/100 second at f16 for the moon OR 1/200 at f11 OR!!!!! 1/400 at f8. How about that - My estimate matched your exposure! Kool huh!

I will second that. Treat the moon like you would a daytime shot.

ISO800. Nice gamma touch, but I wanted to capture the halo too.

Cool. Clearly, I have some work to do.

Thanks for the responses.

Here is a previous attempt of mine at ISO 400. 1/750 CALL IT 1/800 at f9.5 - Should have been 1/400 at f16 or 1/800 at f11 - so it is slightly underexposed I think http://pathfinder.smugmug.com/photos/2287088-L.jpg

The dynamic range is likely too much to capture in a single exposure. Maybe with RAW, but I doubt it. Likely you will need to do a large bracket shot of at least two exposures and stack the images later in an image editor.

very quick hack job... used a cooling filter too:
