Crescent Moon Setting Sail is BEST seen full screen.
Setting the mood:
The layers of ridges, the dark civil twilight slowly encroaching into nautical twilight. Then the stars will start to come out. Setting very quickly, less than a minute left before the horizon rises to cover the “Sail” of the ship so far away. The first ridge (black) is 40 miles away from my lens. The second Ridge is the Big Horn Mountain chain 130 miles out from my camera. Look carefully to see the outline of the whole moon. This is all very Subtle and it was quite dark for this capture.
I seldom see such a clear sky on a night that had very heavy alpenglow. (Starts out red, goes to orange and then this umber color. This is certainly the best moon sail I’ve ever captured this late in twilight. (just minutes before Nautical Twilight) Not having grain in an image like this is a gift. Only the moon edges blurred by several hundred miles of atmosphere is coarse.
Being a student of such things I think it worth noting that being able to differentiate the two ridges in this image or see the un lit side of the moon is almost magic (high technology we don’t understand) This is a brand new Sony Alpha 7R4 camera back and the dynamic range on this camera is PHENOMENAL. It also gives me 100 meg raw files to begin with 🙂 (60 meg .jpg out of the box). Put it on good fast glass and it’s a Monster for low light.
Dynamic Range??? What is that?? Low light??
. The Human Eye has 20 f-stops of Dynamic Range.(DR) This newest Sony has 15 f-stops of DR compared to less in MOST other cameras. The ability to see black cats in a coal bin and make out the individual hairs on the cat is good DR. . DR is all about seeing MORE levels of black or whiter on duller whites between. Seeing a white weasel on snow and picking out white hairs is all about DR. Or in this case, resolving a difference in what I thought at the moment was a dark silhouetted single ridge landscape but the data was there.
The inability of a camera to take the photo of stars behind a properly exposed full moon is due to that (at least) 5 f-stop difference between the human eye and some of the best technology we use. (as a normal consumer anyway). IF you ever see a properly exposed detailed Full Moon AND there are stars in the background of the image…..It’s a composite image combining a star field in photoshop which is very easy to do. If the artist is presenting it as a photo, he/she is a fibbing a tad.
Stars behind the moon.
I use pretty good (very good) gear and I CAN NOT take a close up (long lens) photo of a Full Moon where you can see the properly exposed details AND have stars in the photo. I see fakes ALL the time. Literally I have worn down a few batteries out trying to do so lolol…It is however, really easy to do it in photoshop all day lol. A veiled moon is easy to get SOME starts through the cracks in the clouds but not an unfettered full bright moon. A single Bright Planet like Jupiter MAYBE. Not a star field….. “ain’t gonna happen”. It goes against the Laws of Physics involved.
