NASA fixing photos again?

[Zeek64]

Thank you all for the welcome!


At the end of the day, I was trying to prove one point and that is that one cannot assume that there is funny business going on based on photographs alone. kucharek is right, different scanners different results

Zeek64, I want to add my welcome to this board too.

Trodas - when are you going to answer the questions posed to you in the other threads you have started. You made a claim, people have responded. You now have a responsibility to read and respond in return.

Something tells me we are going to be waiting for quite a while.

Trodas is taking a little involuntary timeout for not answering questions. That suspension lifts in a couple of hours. We'll see if and when he returns after that. If he doesn't start answering questions, he will be suspended again.

Nothing strange.

I couldn't help noticing the watch he's wearing.

What time zones are on the the moon, anyway?

That's an Omega Speedmaster. If you're seeing extra hands, they're for the chronograph functions, not multiple time zones.

[Donnie B.]

The time zone on the Moon changes about once an hour (give or take an hour or so every four weeks).

Yes, I'm kidding. I would imagine (without any actual knowledge) that the watches were set to Houston time, i.e. either CST or CDT depending on the time of year of the mission.

They were primarily used to determine EVA elapsed time, of course.

Here are links to the specifications for the Biogon 60mm F/5.6 lens manufactured by Zeiss. Page 2 has a graph which shows the light fall-off curves at the maximum F/5.6 aperture and at F/8. It is the Relative Illuminance graph. Note that the light fall-off is pretty bad at F/5.6 such that the exposure value near the corners of the frame is 1 F/stop darker than at the center of the frame. Light fall-off is common with camera lenses and in particular for wide angle lenses such as the Biogon.

To make trodas happy, following are some 5903 photos which I processed from ISD's scan of their original negative. The full resolution versions of the following are on my web site. The following photos are my medium resolution photo versions:

The above photo, cropped, Biogon lens vignetting removed

My aesthetically pleasing enhanced version of the above photo

The original photo with lognormal curves applied, proving that the only light sources were the sun, the lunar surface, and reflections off of the gold Mylar covering the LM descent stage. Note that for this photo, I did not use the photo version where I had removed the Biogon lense's vignetting since conspiracy nuts would demand that I use the original photo to prove where the light sources are (or are not).

If I'm not mistaken they didn't really use any time zone per se, but used mission elapsed time. In other words, event X would occur seven hours, minutes 43 seconds after launch, which is to say 7:09:43 MET.

There are plenty of people here more knowledgeable than I, so I welcome correction.

Must have been an interesting modification to those Omegas, then, to show MET...

"Houston, my watch stopped, can we start the liftoff over?"

Aldrin's watch, at the moment photo 5903 was taken read 11:14 PM CDT. His watch was set to Houston CDT. Thus the photo was taken at 04:14 AM UT on July 21, 1969. NASA, according to the lunar surface journal, thinks that the photo probably was taken at 04:18 UT. Guess they didn't look too closely at his watch in the photo. Here is a link to my own processed version of the original 5903 photo. It is a big image:

He He. There are no time zones on the moon since nobody lives there.

Well, as I said...
