One thing further that might clear this up a bit: when shooting RA but exposing FA (when balancing for RA), one could presumably balance both simply by framing the RA in the center of the FA -- and then printing it to the far right to accomodate the soundtrack. This removes the necessity of shooting anything off-balance, and as with many obvious, simple solutions, eluded me at first. It doesn't address whether extractions for theatrical presentation are taken from RA or FA, though, as explored above.
Ah, and Peter just posted as I typed this up. Thanks for that info, Peter. As to the UE of T2: I have the old DVD-18 I bought when it was first released, but I've only watched it once. If you know off-hand, does that material demonstrate where Hughes would have "found" extra screen info to the left of his frame? I'm wondering if varying productions might not make individual extraction decisions for their 'Scope 2.40:1 frames. One film might extract the 2.40:1 frame from the FA, optically reduce it to fit within RA, and then anamorphically encode it for the theatrical print, whereas another might skip the reduction step and simply take their extraction from RA.
I'm brainstorming about this, obviously, as I'm eager to meaningfully relate the varying statements I've encountered about Super35 to one another -- and my apologies as we drift further to the periphery of Kate, of course! But ironing out Super35 and FA photography in general should be of use in better appreciating the merits of home video transfers from these formats (I'll throw in one more Super35 comment I've run across for digestion: in his commentary for Ronin, the late great John Frankenheimer said that Super35 has a "hard top" allowing for the opening of his frame to the bottom ... he's obviously not talking about a simple center extraction, where both the top and bottom of the frame would be open, so perhaps they shot to balance the frame at the top of the negative? That seems unlikely; another possibility is that he allowed booms and other production junk into the frame above, necessitating a hard matte when they took their extraction).
The matter remains convoluted. But continued thanks to all for their input. Here's another question: Peter says that Super35 is rarely if ever used for flat prints to theatres in RA reduction (designed for flat matting to say 1.66:1 or 1.85:1). Is there a technical reason for this? I'd assume optically reducing Super35 in extraction for 'Scope printing is fundamentally similar to reducing a flat FA frame to RA for flat printing? Since flat Panavision uses spherical lenses I'd presume are not necessarily any different from the spherical lenses used on FA photography (the only difference being in the amount of light they allow to pass through to the negative, i.e. the aperture?*), is there a technical obstacle to photographing FA for the increased image detail Robert Harris mentions when reducing for flat printing?
* One last thing: a couple of months ago, on another thread, we got into apertures, and another member said that the aperture of a camera is set when it's manufactured and cannot be changed. Is this the case? Somewhere (I don't know where) it seems I've read of multiple apertures in use for multiple photographic needs (night photography versus daytime photography, indoor versus outdoor, etc.). Is there a camera or lens aperture that one adjusts, but a negative aperture that remains constant? Or does the term "aperture" apply solely to the amount of image appearing on the negative (the dimensions of that image), a measure which never changes (at least within a single camera) during a production? Such info is valuable to prospective filmmakers, of course, but moreover for us film fans who'd like to know just what directors and cinematographers mean when they discuss these decision-making processes in relation to a film's production.
If there's a simple answer to any of the above (or a complicated one -- goodness knows I never shy away from complexity! ), I'm eager to find it. Thanks again.
