Considering Bob has given us an excellent download image, I will record his excellent settings and image. Unless there is a major hit on the moon by a just missed the earth comet the surface of the moon will not change for one hundred thousand years.

Lindas List: (Thank you Linda for bringing up a subject full of lessons ... and no Astro-equipment is not necessary. Tho a home built 90" telescope would be nice )
1, Depth of field is not relevant if you are shooting just the moon itself. I could joke about the Flat Earth Society extended to the moon... but she is right from our point of view DOF is irrelivant.
2, Shutter speed is relevant because the moon is moving and you or your camera may be also. Yep, but at 1/500 camera shake and moon motion are irrelevant .... reminds me of the Movie "The Earth Stood Still." I never use a tripod.. [ok very rarely such as long exposures with ND filter or holding slave flash]
3, ISO is relevant because many cameras produce better quality images .... Yes, Linda but much less as cameras and edit-ware improve.

I recall reading a long time ago that the moon is to be treated as a daylight image. Bob's settings are daylight values. I was surprised at an IR image of the moon that I took, the dark is not dark it has a glow. " That pale glow on the unlit part of a crescent moon is light reflected from Earth. It’s called earthshine."

Your head hurts ? Not your fault. It's not a good
article. All that stuff about wave interference is
overly complex and NOT very relevant.

What is relevant is that light beams bend a bit
off of their course upon encountering a crisp or
well defined physical edge. No need to realize
that those beams are made of waves. You can
easily ignore wave physics !

The edge of the aperture iris blades is a very
well defined edge, so it bends light beams off
of their normal path.

Any beams that aren't behaving in the manner
that the lens elements have "ordered them" to
behave are NOT part of the sharp well focused
image emanating from the lens elements.

At wide [large] apertures, and also at middle
apertures, the proportion of light beams that
never skim the edge of the aperture iris will be
hugely greater than the amount of beams that
get corrupted by skimming past the iris blades.
Realize that you'll have some corrupted beams
at every aperture setting, but when they are a
tiny fraction of the whole image they can't do
any visible damage.

The diffraction problem is due to the increase
in that "tiny fraction" at small apertures. The
amount of corrupted beams won't outnumber
the intact beams, but that minority of beams
that get corrupted by diffraction will become a
more influential minority and visibly degrade
the overall image.

Thaz the whole story. Take two aspirin and
forget about wave interference patterns :-)

Both explanations are excellent. There are Science geeks and Tech geeks ( and there are some in the audience who are both :) ) The visual backup in your recommended article was appreciated.

As I said, "... some other articles suggest that the Z6 has an AA filter."

My point is, so what? Have you ever seen moire in an image that did not include clothing, window screens, etc.?

Since moire is often the result of the coincidence of fabric patterns with sensor spacing, why would increasing the pixel pitch matter if moire simply shows up at a finer pattern of weave or a different subject distance?

I see moire all of the time on TV when a talking head happens to wear a piece of clothing with a pattern coincidentally interfering on my 4k display. It might not show up on a display with a different pitch or when the subject distance changes.

I use iso-100, lowest available f-stop (lens wide open) and change the shutter speed until I get a good contrast of light and dark areas in the live view lcd screen. I shoot hand held and raw. This always seems to work for me with every camera and lens. Then I crop in Photoshop and tweak the contrast, shadows and highlights. It seems the longer the focal length the better. The attached was taken with the Coolpix B700. The focal length is listed as 361mm, though with the small sensor the equivalent focal length is 1440mm. Because it's the moon, the small sensor's lack of EQ and color depth doesn't matter. The shot was taken at iso-100, f6.5, 1/500 sec.

Thanks for posting! This topic is about discussion of settings, specifically why you chose them and why they work for you. So please elaborate on what I see in exif as f/11, 1/60 sec, and ISO 31???

Appreciated!

Never use this rule. It is totally obsolete. And how would you use it at night? Spot meter the moon. All you care about is how bright the moon itself is. You will be surprised how bright it is.


With respect, how can a rule, Sunny 16, that has worked for decades be obsolete? If it still works, and it works just fine for people who use it, then it is still a viable concept for taking photos. Nothing has changed in photography that would make the rule obsolete. Explain please.

I have never seen an image with moire that did not include clothing, screens or other man-made materials.

Feathers don't count since in that case moire does not detract from their beauty.

Perhaps you might like to post some evidence of this claim on a separate thread. This may not be the place to pursue this question.

2. Shutter speed is relevant because the moon is moving and you or your camera may be also.

3. ISO is relevant because many cameras produce better quality images with lower ISO.


It is amazing how many people don't understand that Looney 11 (or even Sunny 16) is a guideline - not a hard and fast rule. If you set your camera to F/11, ISO 100 and SS 1/125th and your photo is too bright (overexposed) for your liking, it doesn't mean you have to accept that... increase your SS or decrease your Aperture a stop or two and take another shot.

I see so many people posting moon images with an ISO of 1600 or even higher! WHY is the only question that comes to mind but, you can't ask that without hurting their feelings. I suspect many of these people use Auto ISO.

The surface of the FULL moon is very bright - it's like taking a photo at noontime on a bright sunny day. You normally would not set your ISO to 1600/3200 under those conditions unless you were looking for a very high shutter speed so why do it at nighttime on a FULL moon. Many people think that they set their ISO to 1600/3200 for night skies so that's the setting they should use for FULL moon photos too.

I usually use between f/7.1 - f/11, ISO 100 ss 1/125th for my FULL moon photos and I will adjust my ss to get the exposure I think gives me the best exposure.
I never use anything but an ISO of 100. Could I? Sure! but, if I'm handholding the camera, a slower shutter speed is not going to be my friend.

One way to think about your settings is to use the aperture that you consider it's "sweet spot" and adjust your ss accordingly.... keeping your ISO as low as possible (which means 100 for Canon, 200 for Nikon).
I also use Manual focus and LiveView so that I can zoom in to set my focus.

There are two possible answers that come immediately to my mind that answer why:

1. the user has not yet learned the basics of exposure (and specific to shooting the moon, your own observation "but it's nighttime!" )

2. it was an oops moment

This topic was intended to help address answer #1.

Hurt feelings? Where and how you ask why is obviously important. But anonymity without repercussion, except in the most egregious instances, is where we are, so it's easy to be rude and mean. And easier now that Admin has removed the topic "blocking" function of the Ignore button

For #2, I'm pretty sure most of us can relate.

Many thanks for your interest and conversation!

I have not seen ISO 200 as a minimum for Nikon since I got rid of my D70. Base ISO has been 100 for a long time.

On the other hand, ISO 320 is the base ISO for the Leica Monochrom sensors, partly because they have no Bayer array and no AA filter at 18 MP or 24 MP.

Thanks for pointing that out.
The point being - Use the BASE ISO for WHATEVER camera you are using.

Great points! I always follow these three steps.
For me I also like to use a tripod, mirror up (Live View) and manual focus.

I used to recommend base ISO at all costs until I carefully reviewed a lot of the images I had been shooting.

I can only begin to see noise in images captured on a D610, Df or A7 II starting at ISO 800 (I have to look very closely to find it). It become more apparent at 1600 and above.

What I have found is that, with most modern cameras, there is a practical advantage to using a higher ISO - higher hand-held shutter speeds.

So, at least with my own choice of subject matter, I feel safe using anything from 100 through 400. ISO 400 lets me hand-hold at reasonable shutter speeds in daylight when following Sunny 16 - 1/800 @ f/11. The main thing to remember is that Sunny 16 does not mean setting the aperture to f/16.

For egrets with a long telephoto lens where noise is not an issue, I prefer ISO 800 and 1/2000 @ f/11. I would use this setting for the moon as well and brighten the rendition in PP if necessary.
