1. The presence of an atmosphere scatters some light (hence our blue sky). Not a great deal is lost (only about 10-15% at earth sea level, which is bugger-all when talking about exposures and seeing stars). In regard to general viewing/photography, it had very little effect except for two biggies:
Now see how you are misleading?
You are quoting an average based on all conditions..
No misleading at all. It wasn't an average - I stated QUITE CLEARLY, that I was talking about at SEA LEVEL. Looking towards the horizon would OF COURSE involve more losses (gee, maybe that's why the Sun is often reddish at sunset, :duh..
DJ, can you take pictures of stars during a typical Earth day? No, not normally.
Can you take pictures of stars during a Moon day? Yes, with the right exposures.
Thats how I read JW's quote without looking into its context of the conversation.
Sea level?
CHRLZ I dont think SEA LEVEL (height of the ocean's surface) has anything to do with horizon.
You care to elaborate?

I suggest you google "altitude + horizon." In this context, "sea level" is an altitude. Think and/or do some research before you post.

In other words, you agree with Jarrah if you take him out of context. Wow. Why do you find it necessary to take him out of context? If you simply look at what he means, he's just plain wrong. Raylegh scattering does make it impossible to see stars below a certain magnitude on Earth during the day, but it is not impossible to see bright celestial objects such as supernovae and planets:
This photograph was taken in broad daylight... albeit during a solar eclipse. Note that Mercury and Venus are clearly visible, as would be Sirius and Rigel were they above the horizon. Note also that the landscape, darkened by the eclipse, is properly exposed.
Why are you willing to twist Jarrah's words in order to agree with him?

I'm not arguing, I'm trying to provide you with the tools to answer your own question. Do you honestly not know what "sea level" means? Do you honestly not know about the relationship between altitude and horizon? Wait... do you not understand the relationship between the radius of a planet and the visible horizon at a given altitude? That might explain a lot of your confusion when looking at photos taken on the Moon. Seriously, go to the on-line resource of your choice and look into these questions. (Before you embarrass yourself further.)
Jeezas H Christ do we have to sit here and split hairs just so you can
gain some virtual brownie points in your vendetta agains JW?
DJ, you took a quote from JW that obviously was part of a long discussion.
As I said, I have not studied this conversation to know what context JW was making his statement.
1) Mr. Windley, whilst on the moonset you demonstrate the function of the Hasselblad 500: You clearly show that the camera was operated with mechanical stops on the lens, which would grind to click with each turn. To be fair, it would be possible to use in an atmosphere. But in a vacuum, all air in a trapped environment expands: thus the fingers of the gloves worn would have inflated, so how do the astronauts know they are even touching the camera? Which of course weighs only 1/6th of its normal weight, making the pressure on the stops not as great. And in a vacuum, unless you want to try and disprove me with your scientific vandalism, the sound of the proper focus slotting into place would be absent. Rather than putting on the spacesuit yourself and attaching it up front, you simply held it to your chest with the delusion that you were equally as handicapped as
the Apollo astronauts were they really on the moon. Come to think of it, not only were you not in the suit you, a) were not in 1/6th gravity. b) not in a vacuum. c) not in a 105°C. environment and d) (Your ultimate downfall) were not in a nuclear waste zone to simulate the radioactive contamination on the moon's surface. Am I going too fast
for your pea brain? Let me go slower. Your photographs are invalid because you did not use a controlled-simulated environment.
2) You point out that shadows are pointing in different directions because of rough terrain. Well we as conspiracy theorists with an understanding of lighting and shadows would have been more than happy to swallow your pill had you not deliberately ignored pictures that feature shadows pointing in different directions on SMOOTH surfaces. Just as you deliberately ignored pictures and videos that feature astronauts black as pitch when they walk into the shadows, without the light bouncing off the surface and illuminating them. Like this
picture of Charlie Duke (assuming that's him in the costume) img.photobucket.com... If the light can reflect off the surface of the moon and light up Duke's suit, then surely it can reflect of the pit at the bottom of the crater behind him and illuminate the slope leading down into it; yet the crater is still as black as pitch. In fact, the video from
Apollo 11 shows the astronauts not getting lit up when they should be (according to your propaganda), you can purchase a copy of it for $29:95 US, its called "Apollo 11 Monkey Business." I guess the reflecting light must be having a day off.
3) "We're going to find out that if we use an identical camera, loaded with identical film we wont get stars" The only problem is, as I said above, you are not using an identical environment. You were taking star photographs in an atmosphere, where light is easily absorbed and scattered in all directions by molecules in the atmosphere: no wonder you didn't get stars!
4) You say the flag continues to wave after it has been planted by the fact that its aluminium pole is very springy. You even demonstrate this in your moonset; but there is a difference between
the flagpoles supposedly planted on the moon and the flagpole you used on Earth: It didn't spend four days subjected to solar bombardment, you can say that the light will reflect off, but that wont stop heat from building up. If the sun can raise the moon's surface temperatures to 105°C, then surely it can raise the temperatures of the spacecraft's exterior; where the flag is transported. Through all that constant bombardment metal would have absorbed the solar heat and the heat would have caused the aluminium to expand, thus stiffen. So how can the flagpole possibly be springy?
Until you can conduct a proper experiment Windley, your results are [expletive deleted]. What next? Are you going to go round insisting that the moon is made of cheese?

How is the light the same?
What do you think is the light source, anyway, on the Moon? Now, how about on the Earth? Any guesses?
Is it the same source? By any chance??
Who cares about the source?
Just because the main source is the SUN doesnt mean we experience the light the same.
During the same period on Earth the light looks different, the temperature is different at different locations on our planet. I can be wearing sunglasses in the tropics and have no need for them in Northern Europe.

Once again you have not stopped and thought about what you posted - you really should try it, you may realise you are posting rubbish here!

Yeah Ok, wearing a hat and off the counter sunglasses will protect you on the moon as on Earth. You go with that.
Gene Cernan's Apollo 17 Lunar Module Flown Sunglasses and Beta Cloth Case. Manufactured by American Optical, 5½" size, 1-10 12K GF, with a NASA part number of "SEB12100033-201" and serial number of "60" printed on the right earpiece. There is a small piece of Velcro on the left earpiece to facilitate attaching them to the spacecraft control panel for safekeeping. The Beta cloth case has a hard plastic liner and a tag sewn to the top with the following information, "POUCH, SUNGLASSES/ SEB 12100034-203/ S/N 1054/ MFG. NASA MSC 3-70". Cernan has hand written on the back of the case, "Flown on Apollo XVII to Lunar Surface Gene Cernan".
To protect the astronaut's eyes from the extremely bright and unfiltered sunlight that could enter the windows of the Apollo spacecraft, each astronaut was provided with a pair of sunglasses. These sunglasses were worn by Cernan during the historic final mission to the moon in December 1972, both while aboard the Command Module America, and on the lunar surface in the Lunar Module Challenger. Complete with the Beta cloth covered case, these sunglasses were an important part of Cernan's personal flight equipment, as he became the last man to walk on the moon. From the personal collection of Captain Gene Cernan accompanied by written authentication by Cernan. link to source : historical.ha.com...

Apollo 17 CDR Gene Cernan my hands were nothing but blisters. The skin on my knuckles was gone. It took three months for lunar dust to grow out from under my nails. It infiltrates." the blisters we had on our knuckles and it felt like our fingernails were driven back into the joints?"

And then you have examples with no rover tracks.
Besides the over-sized astronaut, this photo also has issues with disappearing tracks:

Firstly, and I've said this numerous times in this thread already, USE HIGH RESOLUTION IMAGES!. There are NO excuses not to be using them.
Because if you did that, you'd see that they turn a bit to the right and get cut off from our point of view as they go down a slope. You can see the tracks continue on in the distance. It also helps to look at the preceding and succeeding images as well.
