Barely on Topic - LF Film conundrum 8)

Joe Lipka · Sep 4, 2003

I worry about things most people aren't aware of. Like film size. In the US it's 4x5 and 8x10. In the UK it's 5x4 and 10x8. I'm OK with that. There's proper English and what we speak in America. Descriptive terms can be different.

In this forum we know the other guy (gal) is wrong in describing film size, but we are polite about it and get on with the photography.

Now, can some one tell me why it's 5x7 film on both sides of the pond? Why not 7x5?

While you are at it, can you explain to me; if nothing sticks to teflon, how do they make it stick to the pan?

David A. Goldfarb · Sep 4, 2003

Clearly, over there they shoot verticals with 5x4 and 10x8, while we shoot horizontals, but everyone shoots horizontal with 5x7.

Huh?

Teeny - really **tiny** screws - lots of them.

With nuts and self locking washers?...

now that the teflon question has been answered: why are women's prisons called penal colonies?

To add to the confusion:

On mainland Europe we (/they) use metric sizes. Instead of 4x5" it's 9x12cm, 5x7" is replaced by 13x18cm, 8x10" by 18x24cm and so on.

Further confusion: A sheet of 13x18cm film measures almost exactly 5in x 7in, and so is a little bit larger than a sheet of 5x7" film. "A little bit" in this case means "just enough bigger that theyre not interchangable". But not enough that the difference is easily seen. You only notice when the film jams when you're trying to load it in the holder (13x18 in 5x7 holder), or drops out when you insert the dark slide after exposing the film (5x7 in 13x18 holder). I know this, because I've tried it both ways (Norway gets both sets of sizes)...

A vertical conundrum: As you see, we always state the short dimension first. Yet nearly all the cameras I've seen that are old enough to have fixed backs (like my 1934 Voigtländer Bergheil 9x12 plate camera) are vertical.

So we shoot verticals with 9x12, 13x18 etc., and the British shoot horizontals with their 5x4, 5x7 and 10x8's...

While we're all trying to unscrew the inscrutable, allow me to chuck in my current favorite oxymoron:

"Debtbuster loans"!

I call them 7x5's but then I beg to differ !

Yes, they have knees, but like all birds, they may not be where you expect them to be.

Teflon is stuck to the pan mechanically. The bare pan first has a texture cut into it. This texture is sawtooth in shape. The texture is rolled over to mushroom the peaks of the teeth. Next, the teflon is applied and trapped or bound to these little mushroom closed shape areas. Interlocked. Does that make sense?

This sounds suspiciously close to teeny, tiny screws......

Looks like they DO have knees !

Tom Perkins · Sep 5, 2003

No, they start out with a sheet of stuff with equal components of sticky and slick. Then they turn it inside out, which makes all the sticky stuff go to one side and all the slick stuff to the other. Then they have to put it in the pan, sticky side in, being careful not to get their fingerprints on it.

glbeas · Sep 5, 2003

FWIW Teflon is baked on like a ceramic. Comes out of the oven slicker 'n owl sh*t.

Ole · Sep 5, 2003

Sounds like a complicated way to make penguin's knees

BTW, Aggie, how do you get the lemon pips off the films?

Aggie · Sep 6, 2003

MikeK · Sep 6, 2003

Real time in a darkroom. Does that really exist. I always thought stepping into a darkroom was like crossing over to another dimension.

BTW, Ole, lemon pips off film, surely you zest
