Perhaps your not real smart, my question was the pictures of the earth. Did not say a thing about the moon,and your reply really makes me check,if it was not for the T&C, my self.

one more dumas bit the dust,thank god for the ignore button

Well -- maybe you didn't count the ones near the end of the film magazine, but if they were poorly centered pictures, I counted them. It shouldn't matter whether it was a poorly centered picture taken towards the end of a film magazine in the middle of the magazine.


quote from ATS: 'Official NASA Photos'

And so on most of the rolls of film, the first frame and the last four or five frames will have streaks, spots, blurs, and other symptoms of light leaking into the magazine when it wasn't attached to a camera.

from original source
www.clavius.org...

So If you know that first and 5 last frames will have problems, you will take them as dummy to finish the film fast and change magazine.
Now, if you want to count these 5 pictures. why not ?

I take a break before finishing reply.

Thank for your post.

Thank you very much, now my next question would be when we see pictures on the moon, of say the horizen and part of the land scape, is that the same reason? Oh for the one I'm ignoring we don't see stars during day light because of the atmosphere but there is not any in space and /or the moon has very little.

Ops read your reply again I think you answered my question. ty

If you look at the original 5903 at

Theres something missing...the photographer.

The shadow on the visor is that of the subject....anyone explain that please?

Who ever wrote that website in the OP clearly has no idea what they're talking about...

Quoting from the site.

Heat protection: Any heat protection for the camera is missing for temperatures on the moon of plus 100 and minus 100 degrees C. The cameras are only painted in silver for that.


The temperature of the Moon has little to do with the temperature of the camera. Just because the Lunar surface can reach over 100C doesn't mean the camera will ever get that hot. Different materials reflect and absorb heat at different rates. Something that's shiny and silver will reflect most of the Suns energy and thus will not absorb much heat.

Education: The astronauts have no photographic education. They have no idea how to handle a manual camera with exposure time, shutter and sharpness. The astronauts would not be able to make perfect fotos with a Hasselblad 500 EL even on Earth


This is an outright lie. The astronauts spent lots of time practising with the camera's on Earth. Plus, operating a camera isn't exactly rocket science, it doesn't take long to learn the basics. And I'd find it highly unlikely that the astronauts hadn't ever used a camera before in there life up until that point.

Also, from the
Apollo 12 LSJ


Conrad - "We practiced this...I started out by just laying rocks around on the floor. One of the things was setting the camera deal; we had the three (focus) distances. And what we did was actually take pictures to calibrate ourselves. They developed that film in training to make sure we stood the right distance."

Bean - "We had to point that (chest-mounted) camera without a viewfinder. (But) we didn't miss a (single) one on the Moon, I don't think."

Conrad - "Yeah, and it was due to the training. We really worked hard at learning to estimate by eye what the camera settings had to be."

Bean - "The first ones (we took in training) weren't very good. But on the Moon, they were all good. So we really had learned in training how to do it by using real film, having it developed, having it debriefed. I think that's why the photography got better with each mission, in general. Because the photographers would impart the (experience gained on a mission) to the next crew and help them be better. So they did get better. And I thought the photography did too."


Factor time: All in all a Hasselblad 500 EL is absolutely unsuitable for fotos under pressure of time because with a Hasselblad 500 EL much consideration and time is needed for a good foto, but a "moon walk" lasts only some hours


The point of the Apollo photography was for documentation purposes. They weren't trying to take "good photos" (by good photos I mean nicely composed shots with nice lighting), but simply just documenting the mission and the environment.

I think I'll stop there, as I don't want to spend hours on this post. It's clear that the guy who put this site together hasn't researched the subject enough and I see a lot of the same old tired arguments.

If you look a little farther back you can clearly see a nother astronat in the back ground. Sry about my spealing am in a herry

Here's a high resolution of that photo. I can see the reflection of the other astronaut quite clearly. www.hq.nasa.gov...

I own a Hasselblad 500 C/M. It has a ground glass framing element on the top, not the back of the body. The astronauts would simply have to look down to see at least part of the image if not all of it, making composition a fairly simple process.

The article state that you can't look done through the helmet.


Additionally, considering they are constantly bathed in the brightest of sunlight, the cameras would easily have been preset with a very small f-stop and a predictable exposure setting...the light source would never change in intensity after all.

I'm not a photographer. but some basic knowledge.
The light source is the sun. his intensity is fixed. Yeah.
If you are in the shadow of the LEM or on the other side, the light intensity on the subject is very different. No ?
You have to tune the diaphragm or time exposure. No ?
I don't really know but as you have the same model of camera, your post are always welcome.

I don't know for stars.

But earth and moon have some differences.
Moon dust reflect only 7% of sun light.
The moon don't have atmosphere. No diffuse light.
Wikipedia



Good:
The Moon's surface is airless. On Earth, our thick atmosphere scatters sunlight, spreading it out over the whole sky. That's why the sky is bright during the day. Without sunlight, the air is dark at night, allowing us to see stars. On the Moon, the lack of air means that the sky is dark. Even when the Sun is high off the horizon during full day, the sky near it will be black. If you were standing on the Moon, you would indeed see stars, even during the day.

He says there are two spotlights hanging from the ceiling of the studio that the photos were taken...but where are the two shadows? each object should have two shadows.

I have it is not an astronaut nor does the focusing distance of the 80mm f/2.8 Planar T* (20028) 35mm eq 50 mm equate to the white square you see as the photographer at the back of the visor.

from wikipedia: Surface temperature


During the lunar day, the surface temperature averages 107 °C, and during the lunar night, it averages −153 °C.[49]
Temperature surface cause there is no atmosphere.

So I'm agree with you that the temperature of the camera wil change depends if it's lighted by the sun or not. I don't know if the camera have a heating system but it's have to operate between -100 and 100C about.
I don't have data about the camera temperature. I will check.



Education: The astronauts have no photographic education. They have no idea how to handle a manual camera with exposure time, shutter and sharpness. The astronauts would not be able to make perfect fotos with a Hasselblad 500 EL even on Earth This is an outright lie. The astronauts spent lots of time practising with the camera's on Earth.

I've already say it. They are not beginner.
So I'm agree with you.
I will search for training datas.
But professional camera (not automatic) without seeker in a space suit very rigid (first model), not so easy. Need training, sure.
And as your quote show it, they have direct live confirmation from control center for camera settings.


118:07:57 Conrad: Yeah. Yeah. Yeah. Yeah. (Pause) Want to get a picture of that? 118:08:03 Bean: Sure do. Let me get it set up. (Pause) Right. (Pause) 5 (foot focus) at f/8. (Pause)

But this is apollo 12 log. I will check for apollo 11.

for focus, I don't know.
can a Hasselblad 500 give his opinion ?

And many of these "not so good pictures" were in cover of famous magazines.


OPwork: Please, each picture of the frame have allready been discuss in multiple other threads. Please don't make this thread focus only on a single picture.



The article argue that:

Under the circumstances -- with a camera fixed on the chest -- in an astronaut suit where it's not possible through the seeker -- without the mirror in the seeker (Wisnewski, p.157) -- with "moon astronauts" without long experience in making fotos (Wisnewski, p.153) -- with radioactive radiation which has a negative influence on the films (Wisnewski, p.157) perfect, sharp "moon fotos" with partly perfect arranged sceneries are not possible (Wisnewski, p.157).This is NO conspiracy theory, stupid Wikipedia, but these are facts.
