eclipsed moon
Oct 13, 2014 20:09:44 #
I missed the first part of the eclipse and got the camera setup for the waning only. It was late (early), I was half asleep and I couldn't figure out how to get both halves of the moon correctly exposed. Is it possible, or does one have to take two photos and stack 'em?

Sounds like you need to get up a little earlier and have some coffee next time, drcjc. LOL
Good try .. but the moon is not sharp. I am very new at moons myself, but I know I do better with the focus if I autofocus at the edge of the moon. As far as the exposure goes, I image you need a grad filter to deal with an image like this. I too shot this moon, but I didn't have the exposure problem. I haven't posted because I'm not sure if I got it sharp or not. I will look and see. If so I'll post so we can compare notes. :-)

Thanks, Nightski
I'd like that!
I'd like that!

Okay .. hope some more experienced photographers than me help out here. Why does my eclipse moon look more like a waning moon and drcjc's eclipsing moon look more like a eclipsing moon? I know he's got some blown highlights, but I think his is better .. he just needs to expose for the bright part more effectively.
Would a filter help?
Why didn't mine have a bright part?
What time did you take yours drcjc?
Here is a link to mine. If you don't want me to leave a link, I will delete it.

Yours looks like the eclipse is just starting (or is very near the end). Mine is almost finished. I suspect one can't expose for the really bright moon and the eclipsed red moon in the same photo. I was so rushed I couldn't think -in addition to which I was in my pjs and feeling a little odd on the patio (and then on the deck on the other side of the house)! I hope to try again for the next one.

Me too. I'd like to try again. I'd like mine to have that eclipsing look like yours does. I think the grad filter is the way to go.

When I shot the lunar eclipse last week, I found that at its peak, an exposure of 1/4 sec @ f/5.6 with ISO 3200 was needed. Using the "luney rule" for a normal full moon, an exposure of 1/3200 sec @ f/11 with an ISO of 3200 would be typical. What that means is that there is a 12 stop difference between a normal and eclipsed moon! I'm not aware of any graduated filter that has that kind of gradation.

So how do you expose for something like this?

It depends on what you are trying to show. If you wanted to show the eclipse shadow as it moves across the moon, then expose for the sunlit portion. However, the redness probably wouldn't show up. If you wanted to show the blood-red portion of the moon just before (or after) its peak, then you would expose for the eclipsed portion recognizing that the sunlit portion will be blown out.

I am thinking that it would take two photos - one each as you describe then combine in PP.
