It's silly for armap to say they're ice crystals near the shuttle. A telephoto lens wouldn't even see them. And the disks did not behave like real ice crystals which don't have force of travel unless they emanated from a water dump.

So YOU must have the specification of the camera and lens to know it's depth of field so why don't you show us those specs I am sure all of us into photography on here would like to know.

The tether was at a vast distance so a normal lens would have been useless. They either bring out a long telephoto lens or they use a super zoom lens. That means that only the distant object will be in focus and everything in its vicinity. …..

I should have known better than to get involved. I have no concept of what is seen around the tether but I'll never accept your explanation nor those given by astronauts who suffer from pregnant pauses.

Once one side pulls the get-out-of-reality-free card by hinting that any contrary testimony is falsified, you're right, further discussion is useless.
Just out of curiosity, did you ever look at the 70mm photos or the external camera operating manual, or are you satisfied you already know all you need to know about outer space phenomena?
As usual, your feelings led your intellect astray. I treasure the existence of people of sharply opposing views.

Thanks for the constructive response, don't be a stranger. People like us should live forever.
I have a feeling your reply was made while I was typing mine. Read mine again.

Hi I have been a keen hobby photographer for almost 40 years bought my first SLR just before my 17th birthday. Jim linked to a document re the camera. First the lens name you were after re architectural photography is a tilt shift lens it is to ensure parallel sides to buildings when pointing the camera up. Depth of field depends on focus distance aperture and focal length. So unless you have ALL the info you cant assume as the focal length of the cameras was NOT huge at the telephoto end and the cameras appear to have a SMALL ccd sensor the depth of field would be greater than you assume. Also as the focus was done manually if you get to the hylerfocal distance for the lens everything from a few feet to infinity would look in focus so small objects closer than that may still show as out of focus highlights.

Lets have a little look shall we lets see if you spot the obvious here is a video
snip
Now at 0:55 in the video do you think the tether is in focus, the tether is around 2 mm yes 2 mm in dia.
Do YOU honestly think it's correctly focused on a 2mm wide object.
Also as for the interaction of ice crystals what do to think the mass of the shuttle about 165,000 lbs when empty would have on objects nearby weighing a few grams. Have you not also considered these objects will collied and interact with each other.

Shrike, you seem to be more clueless than I could have imagined. Do you really think water ejected from the shuttle just hangs around in space until the shuttle orbits around the Earth again?
