Quite right! I kinda forget that as the amount of light changes the color perception changes as well. Also nailed the location - Kansas.

I am doubtful that this photograph is resolving the disc of Venus. I think it's Just coincidence that the saturated blob at the position of Venus is the correct size relative to the moon (if it is).

It most definitely is. The disc of Venus was exactly that size ( relative to the Moon ) at the time. I have similar photos of Jupiter and Saturn at same relative size where one can see the belts of Jupiter and the rings of Saturn. It really isn't at all hard for a camera with 30 times zoom ( my Lumix TZ80 ) to pick up the disk of Venus...its clearly visible in my telescope at same magnification.
Here's Jupiter and the Moon.... ( someone else's photo ).... https://www.deepskywatch.com/Photography/solar-system/jupiter-occultation-2012.html

Ok. I will stand corrected. What date was the Venus photo? I have never successfully imaged the disc so that's why I was skeptical but it sounds like you may have better equipment than I.

Don't know it there's a way to get your full resolution image.

I took video as well ( Jan 03rd 2025 ) and you are right that my image is a little over-exposed. This segment of video captures three frames while the camera moves, but in the uppermost left such image you can clearly see the half Venus one would expect for that date...though it is over-exposed. The middle image is well over-exposed. And the bottom right one is more likely the 'correct' size of Venus..which is smaller than in my photo. My camera ought to be able to pick up the disk of Venus at 30 times zoom.

I don't know the numbers off hand but I think that the surface brightness of Venus is higher than that of a crescent moon (see my daytime shot) and your moon looked saturated or on the edge of it and that is why I thought Venus would be saturated too. And I also thought I saw chromatic aberration on your first shot, too.
I was camping in the Welsh hills last night and saw a Brockenspectre/glory in the inversion cloud shortly after sunrise this morning.

oh, here is one which is some sort of optical illusion (it appears the sun is behind you but it really isn't because the sun is coming up) behind the cloud...
there are other cloud pics on that page (all pics taken by me, i can give precise location and maybe a time for some of them since it is right here and some pics have time stamps or close enough):

oh and this pic is actually one of a series where i went outside and took a bunch of pictures around in a nearly full circle.

Awesome! I lived in Herefordshire for a while, but it's been 25 years since i walked any of this countryside ... Is my recollection accurate that the second image is Pen Y Fan, in the Brecon Beacons?
Still recall stopping for a pint after a days outing in the region: sat at the outdoor tables of Three Cocks Inn, looking at Lord Hereford's Knob. (Oooh, Matron!)
Yes, Pen y Fan is the central, highest, one of the three peaks in the second photo. The pictures were taken from (continuing the rude name theme) Fan y Big.

In case my erudite contribution to the thread has given any welsh members the hump, here are more welsh humps:
There was a good display of solar haloes over southern England on Wednesday afternoon (6 August).
22 degree halo with upper and lower tangent arcs. Contrast and saturation boosted a little.
Just visible at the two o'clock position is a section of the parhelic circle.
Here's a wider view showing the parhelic circle when it was a bit more obvious. (Taken with 0.5x iPhone lens so rather distorted)
I think the bright dot on the parhelic circle is a 120º parhelion.

Circumscribed halo rather than upper and lower tangent arcs I think
https://www.atoptics.org.uk/halo/circim2.htm
You are correct – when the sun is high in the sky the tangent arcs merge and form the circumscribed halo; I didn't know the right name for it.

I don't know how well this shows up in the photo but this was the best view of a supernumerary bow I had ever seen. the extra bands of light are caused by interference, and cannot be explained by classical geometric optics.

Lovely! That's better than my one from last year, (https://www.metabunk.org/threads/photos-of-clouds-and-skies-that-you-took-yourself.2900/post-317436), the second extra band isn't just hinted at, it's really clear.

And, unless I'm hallucinating, you even captured a double bow.
Leifer

Yes, double bow can be better seen with a different photo, shot fairly over-exposed.
Funnily enough I just saw one posted on Twitter today. And it was taken in 2020 according to Community Notes, so not the same occurrence. (Ignore the bizarre description!)

They are known as monochrome or red rainbows. Wikipedia.

Here's one I saw on Maui about eight years ago.
Because it is at sunset the bow is almost exactly a half circle and just has red light as described above.

Saw this the other day. Looks like two wave patterns interacting with one casting a shadow on the other near sunset time. I had never seen anything quite like this and it dissipated within minutes.

Try it upside down. It looks as if the trees are stirring the sky.

Just out walking my dogs, not long after sunset,t and saw this high contrail still sunlit. The photo is a bit "meh" but IRL it looked pretty spectacular and took me back a few years b/c it looked like someone had slashed the Flat Earth dome with a sharp knief and the magical intergalactic goo was seeping into our snowglobe.
