On the other hand, you could use a telephoto lens and make a 1:20 image that would not be panoramic at all.

So what would you suggest as a definition of a panoramic image? One that spans at least 120 degrees horizontally? Should we not consider aspect ratio at all for the definition of a panoramic image?

Hmm. So I get me one of those reflective hemisphere gadgets.

So I put it in front of a lens, set the camera pointing straight up, and capture a distorted 360 degree image.

What's the aspect ratio?

Would you definers of that which probably doesn't need to be defined very precisely classify the image as panoramic?

Howsabout I do all this on 35 mm film? Then what?

If one was using a long tele on a 617 (or even 624) will not get you anything that resembles a panorama, and even more so when you turn it 90 degrees. I don't think subject is a good measure of the cameras panoramicness at all. I might not like the limit running at 2.5:1 instead of 2:1, but that doesn't make it a worse description of what a "panoramic camera" is all about.

Also, I don't think panoramic is tied to film size - a 3:1 Minox is just as panoramic as a 617.

My mistake as a newbie to jump in with both feet and arbitrarily pick 2.5:1. It seemed somehow kind of "seat of the pants" to me and I am ignorant of arguments that were previous. It still seems kind of seat of pants but I rarely stick by any rule. Certainly a 22X48" picture made by a George Laurencian camera would unquestionably be a "panorama". Let's hope folks wouldn't be silly enough to not come to the forum over semantics. A panorama is a panorama. I suppose you could put a 6 inch lens on the Laurence camera and put circular text an inch away from the lens and fill the film up with it. Then it would be a 22X48" picture of text. I could do the same with the Cirkut camera and make a negative 80" long of text. It wouldn't be a panorama. Just me but it seems a bit silly to banter over. I'll see if Sean wants to change the forum to just the Header with no other descriptors.

Wait a second. Jim, your the damnable autocrat that picked 2.5:1? Your the guy that made my 612 Linhof homeless? I cast a curse of fungus on all your lenses. Not even area 51 is dry enough to protect you.

Oh Dear. I better get a 55 gal drum of hydrogen peroxide ordered. Now I've done it. jg

The two approaches are very different.

I think that all of the panoramic cameras, including swing lens and fixed lens, are specialty equipment, and could easily be encompased in one forum.

Standard cameras with cropped negs should be discussed in their respective forums.

View cameras with panoramic backs are kinda on the line. But I'm sure most users will post questions about the backs here and about the cameras in other forums.

Perhaps I am incorrect, but I do not believe that those of us using View or other cameras that produce "Panorama type" images should be excluded from this group. No question that strict Panorama cameras are some what specialized useful tools. But those of us using as an example our 4 x 5 and 5 x 7 cameras with our 6 x 12 and our 6 x 17 backs feel that we should be part of and would like to participate in this group as well. The same should hold true of those shooting 4 x 10 be it on a specialized camera or using a means of recording these proportions on 8 x 10 or cut sheet film. Certainly those shooting on cameras such the Linhof 612 Panorama cameras should have a home here.

Those of us using our view cameras just have the option of selecting the proportion of film that we will use to record our image and have the further advantage of using all those wonderful movements that these cameras offer.

As a fulltime panoramic photographer I use a huge range of equipement and I think of all the formats I use as panoramic.... I`ve been shooting this morning the glorious autumn colours here in central otago NZ...... I used 180 lens on my Linhof 617 the most often this morning because of the strong directional and intense light at the time...... yesterday I was mainly using a 28mm lens on a 220 film Roundshot, this again was due to the prevailing lighting conditions which was a nice soft but bright light giving very even lighting on 360 degree pans.
I use several roundshot cameras , a 10 inch cirkut and 12x20 as well as the 617 Linhofs and a 150 Noblex. The noblex only has an aspect ratio of 2:1 but is most definitely a panoramic camera.

The range I use goes from a 15mm lens on the 220vr roundshot which gives a negative of approx 50mm x 95mm this gives an image which is 110degrees vertically and 360degrees wide and yet only has an aspect ratio of less than 2:1 but is obviously very panoramic ( panoramic literally means to see all ) yet fails to meet the more than 2.5:1 concept.

The other end of the range for me currently is 1200mm lens on the 12x20 ! not a very wide view at all but the 12x20 format is generally accepted as panoramic.
What I`m trying to say is that you can`t put a formula to it... doesn`t make sense to...!!!

The fact that I put a foolish aspect ratio in the forum name when I helped to set it up only reflects my naiveté as a relative newbie to things panoramic. I was working on the 12X20 last evening and I agree most things I would do with it I would consider panoramic. Now if I put the 18" Hyperion on and stand it on it's end for a portrait, well....

As far as exclusion, inclusion, there shouldn't be any. If a guys making negs with a 50mm lens on a 6X9 camera and trimming foreground and sky with a pair of scissors, it's probably a panorama.
