class="style5" Super 35 vs Standard 35

>Published : 26th feb. 2005

>I'm a lurker on this list- sorry, I like to watch.

>Shooting a piece that'll live on tape.

>How much more negative will I gain if I go with Super 35 over Standard?

>I'll be using sperical lenses since some of the 35 will intercut with some Super 16. I'll probably use a 1.77 ground glass.

>My apologies if this is a redundant thread. I'm sure this has been discussed in the past but I couldn't find a specific answer in the archives.

Thanks,

>1.78 (HDTV) on normal 35 will give you an effective negative area of 21 mm x 11,8 mm = 247,8 mm2

>1.78 on super 35 will give you 24 mm x 13.5 mm = 324 mm2. A 30% gain.

>These numbers are based on Arri ground glass specifications for "1.78 TV transmitted".

>The number I remember from years ago, comparing 4:3 Academy aperture with 4:3 full aperture, was an increase of 40%.

>Can anyone confirm or deny?

>It is a non-standard format so I will do the best I can. I recently got this from a friend. hold on it gonna be a rough ride.

>Panavision conservative .823 x .624 .519 sq in. 10.4% larger than tv trans

>Panavision large .900 x .676 .608 sq in. 29.4% larger than tv trans.

>Arriflex, silent gate .925 x .689 .637 sq in. 35.5% larger than tv trans.

>Clairmont camera, super tv, 5 different formats to choose from.

>Otto Nemitz int., super tv .894 x .670 .599 sq in. 27.4 larger than tv trans.

>Ebu r.86 standard, super tv .945 x .709 .670 sq in 42.6% larger than tv trans

>I forgot 1 thing no matter what do a very good framing leader and with each lens if you can. Also, Arri and Pana seem to me to be the ones most places can deal with the easiest.

>Gerard Brigante


>If all other things are the same, then all you need to consider is the relative widths of the two frames.

>Academy (standard) gate is 0.868" wide
Open gate (super) is 0.981" wide

>That's an increase in width of 13%. That's the only number that matters.

>Keeping the same aspect ratio, (doesn't matter what it is) you will get 13% more height as well :
total gain in area (13% on 13%) = 28%

>If you are concerned about TV safe, then that's typically a fixed percentage of the exposed area, so it will still be 28% increase.

>If you go by finder markings, (though they relate to final projector gate so aren't strictly relevant to a tape finish) the widths are 0.825" and 0.945" - an increase of 14.5%. Area increase is 31%.
