Re: [pinhole-discussion] 35 mm pinhole camera
Hi Zami, Sorry for the late reply. The pinholes are 55 mm f 166 with a pinhole diameter of about 0.33 mm and a 105 mm f 318. Actually I prefer zone plate 35 mm photography, I don't like 35 mm pinholes (At least I don't like mine). I'll keep using the 4x5 cameras with pinhole. I transformed the 35 mm pinholes into 2 new plastic lens to use with the camera. Now with this 35 mm camera and the extension bellows I am using 55 and 105 mm zone plates and 390, 210 and 150 mm plastic lens, one of them in even a composition of a positive and negative lens to give me a usable focal distance.

Re: [pinhole-discussion] Angle of ligh
Hi Ishikawa, Thanks for the ilustration. The camera is ready, I made it yesterday, and is almost exactly as you pictured, I made it with cardboard. The main diference is that film placed at the position a is also bended, U shape. The idea is producing a kind of a triptico (I don't know the name in English). I am not sure if it will work, but I'll give it a try and post the results to the upload galery. The next one will probably be a pvc cilinder with the film placed against the wall, forming a cilinder. Thanks for the help with the matter. Joao
Re: [pinhole-discussion] Angle of ligh
Thanks Bill and Guillermo for your answers. But ... Geometrically/mathematically speaking, the angle changes when the pinhole diameter changes, the change is so small tho, that in practice you can dismiss it. Since you want to calculate the cone angle, otherwise known as angle of view, here is a formula I just derived that takes the pinhole diameter into consideration: Cone angle = ArcTan [ (D+P) / (2 * B) ] Where D = Diagonal of your film format P = Pinhole diameter B = Bellows extension (or focal length) As you can see, the effect of adding P to D is very small, i.e., for 8x10, D would be equal to about 325mm if you add to that a P of 0.5mm, you get 325.5mm, again, not a big change. The same happens if you change the pinhole diameter. I'm not sure this is the answer to my question. If I could send a drawing attached to the list it would be easier, but this is what I want: I imagine a light entering the box/camera and forming a cone. This cone will be independent of film size. I believe it will vary with pinhole diameter but maybe not in a meaningful way. Let's say I made a very long focal distance box, no matter the film size, and at the end of the box, parallel to the pinhole plane usually is put the film. But I'll be using just a fraction of the image formed by this cone, the rest will be absorbed by the black walls of the camera box. Now, what I intend to do is to place 2 sheets of film not at the end of the camera, but at the walls that are perpendicular to the pinhole plane. I imagine that the light absorbed by these walls will also form images, certainly distorted (I believe someone in this list have already done that). How far from the pinhole plane the film should be to be completely covered by light? My imaginations tells me that if it is too close I'll have a V shape image. Is this formula you sent me able to give me that info? I'm asking because it takes into account the film diagonal and I believe this cone is independent of the film diagonal, I'm not sure. Sorry for this long post Joao
[pinhole-discussion] Angle of ligh
Hi folks, I have a question, but I'm not sure I'll be able to put it properly. Here it goes: When the light enters the camera, it enters in an angle the depends on the pinhole diameter or this angle is constant? Imagine I have a pinhole of 0.5 mm. If I make a bellows camera and set it to say 50 mm focal distance using an 8x10 film I'll have a very wide angle image. But if I enlarge the bellows distance to 500 mm I'll then have a telephoto image. Well, actually the image cone will be the same, I'm just choosing a section of the cone farther away from the pinhole or origin, and I am also selecting part of this cone to be recorded. How can I calculate the cone angle? Will changes in the pinhole diameter make any difference in this angle or it will always be constant? I hope I could make myself clear! Thanks in advance for any info, Joao

Re: [pinhole-discussion] developing ortho
Hi George, Recently I made a few tests with the ortho litho films I have. I used kodalith, Arista and Agfa darkroom RA. With the first 2 films, LC1 with the dilution recommended by Cor Breukel worked fine (water 750 ml, Metol 3 g, Sodium sulfite 60 g, Hydroquinone 3g, water to 1 l, to use dilute 1:4 with water and develop for 6,5 min at 20 o C), Iso rated is about 1. With the Agfa (and I suspect with all the RA films) the densities are still very high. I am using for this film Ilford multigrade liquid paper developer concentrated solution 50 ml to 4 l of water and I am getting pretty good results, times from 1,5 min to 4,5 min. depending on the density wanted, iso also about 1 at 24 o C. The 1,5 min development gave me a good neg. for gum.

Re: [pinhole-discussion] Calculating accumulated flash for my pinhole camera...
Hi Guillermo, Also, something called intermitance states that although mathematically 80 f/22 flash pops are equal to 1 single BIG flash pop of f/197, in reality, the effect of 80 f/22 pops is less than 1 BIG f/197 pop. Sort of like a reciprocity failure for flashes. Some more extra flash pops should be added to compensate for that intermitance effect. Same happens in the darkroom, a test stripe with 5 x 2 sec test results in different densities than a 10 sec exposure on photo paper. I never considered it for flash pops, though. Maybe because of bracketing the exposures. I will have it in mind next time. Thanks for pointing it out. Joao

Re: [pinhole-discussion] Re: translation GORDY EMERY
Hi Alexis, Paraffin oils have a boiling point in the range of 150 - 300 degrees Centigrade while the wax has one between 50 and 60 degrees. Paraffin wax is used for all sorts of things includeing cheap candles and waxed paper. Actually I think you mean that paraffin has a melting point of about 60 o C Camphorated oil on the other hand I would suspect is not strictly necessary. The oil part yes, but the camphor part was probably used as a preservative as some of you may remember camphor balls or mothball ususally consisting of napthalene and sometimes, yes you've guessed it, camphor. Therefore, camphorated oil was probably used as an amplication for preseving perishable non edible goods in the days of moths. Now all of this is some educated conjecture but I hope it is of use to you. I would think that oil would be sufficient. It's hard to say, in the wet plate process they used to varnish the plate with gum sandarac and in the formula they recommend oil of lavender. The oil is added for flexibility and, as I was told, it has to be lavender. I tried oiling papers with sunflower oil, it works fine but it goes rancid over time and smells pretty bad, so maybe the preservative is important. Paraffin (solid thing) works fine but the paper is fragile after, it marks easily (at least thin paper I use with ink jet printers). I have an old formula here that I have never tried, but maybe it works, who knows, it says: To make paper transparent: Dip the paper in a bath at 80 o C of: Parafin (solid) . 40 gr. Linsen oil 10 gr. After the paper take up all the solution it cans, drain it fast and put it between 2 sheets of blotting paper. Will it work? Who knows, but why does he give the amount of oil in gr and not in ml? This formula dates from 1905, found it in a paper I have here and it has other curiosities. I am just looking up in a dictionary that camphor itself is a whitish, translucent crystaline, pleasant-smelling terpene ketone, whatever that means except that most ketones smell nice from what I can remember at school, used in medicine and in the manufacture of celluloid. Ah ha! There it is, the manufacture of celluloid. Is that not what one is doing when applying the camphorated oil to the paper with paraffin? Probably not. Will sulfuric acid damage the gelatin part of the photo paper? I am working with an Arjo Wiggins Parchment paper called Linaje and they told me that the transparency is obtained by immersing the paper in a solution of sulfuric acid, washing, neutralising and buffering it after. Anyway, whoever got a good formula I'm interested in knowing. Cheers Joao P.S. I have an old formula for turning the wood black, but I don't know how to translate it, maybe Guillermo will help, it says: Extrato de Pau de Campeche .. 15 gr. (what the ... is that?) Cromato de Potassa ... 2 gr. (I believe it is Alumem de cromo ) Agua .. 1000 gr. He says to dissolve the Campeche first in hot water and add the Cromato. The solution is dark violet and becomes black in contact with the wood.

Re: [pinhole-discussion] Re: Blind photographer
Hi Guy, ... not just in the field of commercial/advertising where the photographer's role has essentially been reduced to shooting exactly the mental image of the art director. Think of the word Pre-visualization that pervades all the Photo-101 or Zone System textbooks. Pre-visualization implies that you have a mental image of what it is that you'd like to see on your negative/positive. You see, pre-visualization is something a professional photographer has to use in order to get what is wanted from the picture he is selling. In my professional work, I am selling something that does not exist yet, someone is trusting in my ability in produce it. When I shoot for fun, either pinhole, zone plate or whatever I am doing (I'm getting pretty found of old cameras w.o. a light meter), I am trying more and more to be like a random shooter. I really want the images I get to surprise me. I have a primary intention when pointing the camera to something, but leave a very broad possibilities for what might come from that. Maybe I'm just tired of the commercial work :) Cheers Joao

Re: [pinhole-discussion] push processing b/w film
Hi Murray, Someone posted a while back in alt-photo-list some instructions for developing chromes in BW developers. I gave it a try and it really works, I didn't like the results for ZP, but they work grat for lens photo and PH. Here is what I'm doing: Film Provia Rated iso: 1250 (if you want better shadow details try iso 800) water bath for 3 minutes at 26oC develop in D-76 at 26oC for 16 min, continuos agitation the first 30 sec and after that 5 sec each 30. Stop and fix the usual way. wash for 20 min (the negatives will be very dark, almost unprintable. Bleach in a regular sepia toner bleach wash another 20 min dry (DO NOT USE PHOTO FLO) take the film to you local lab and have the film redeveloped in C-41 (that's the dificult part, they will tell you the film is already developed, so you'll have to insist) The result will be a negative with huge grain and strong colors. Have fun Joao Murray wrote: Anyone experimented with push-processing b/w film to higher ISO speeds, for faster shutter speeds? This may be uninportant for users of big box cameras, because they're not very mobile, but for the handheld pinhole camera this might open up a wider range of photo subjects that don't have to be stationary.

Re: [pinhole-discussion] Help Me Pick A Color Film
Hi Derek, I used to use Fuji NPL but not for pinhole. If I remember well, the S stands for short exposures, like using flash lights or under daylight (not that daylight necessarily means short, specially to us) , and the L stands for long exposures, when working with tungsten illumination. The color shift, I believe, could be corrected during printing even if you decide to work under daylight. If you ever give the NPL a try, I'd love to read about any comparison. Cheers Joao Derek Watkins wrote: Jeff I've been shooting Fuji NPS with great success. Although the maximum recommended exposure is 5 seconds, I've used it at 1 and 2 minutes with no problems at all.

Re: [pinhole-discussion] f-stop calculations and reciprocity failure numbers
divided by its focal distance at infinity. The other way around, actually. Focal distance at infinity divided by the apparent diameter. I know that is what you meant, but thought to mention it for clarity sake. Guillermo Thanks Guillermo,
Re: [pinhole-discussion] f-stop calculations and reciprocity failure numbers
Hi folks, each F stop is the diameter of the opening compared to the focal length of the lens, focussed at infinity. Each f stop admits twice as much or half as much light per unit of time as the next F stop above or below it. F stops are convenient when using a lens, I read somewhere that the f stop is actually the apparent diameter of the opening of the lens when viewed by the front side divided by its focal distance at infinity. It is not the real opening diameter. Can anyone comment on that? Thanks Joao
Re: [pinhole-discussion] process partial 120 rolls
Hi Gord, People have answer about the clip test, I didn't know this was the name in English, translating from Portuguese would be something like tip test. Usually fashion or portrait photographers do that to assure proper exposure/development as they are not bracketing. One thing I'd like to ad is that people usually take the hole roll and they randomly cut a piece at the end, usually just enough to assure one complete frame, so you'll sure loose 1 frame (the one next to that cut for the test). The problem I see, if I understood well, is that you'll be cutting the film yourself to load your camera. It would be a good idea to share with the lab manager your ideas and take them the camera, so they can unload your film directly into the machine. Allow extra margins for the hangers. The lab I work with here in Brazil (Fuji Pro) would do it w/o further problems. Good luck. Joao Gordon J. Holtslander wrote: Hi: More fiddling with my multihole panoramic camera.

Re: [pinhole-discussion] Recommended Exposures onto Paper
Hi, Someone once told me that the ISO P, the one we find with the paper instructions, is 1/100 of the film ISO. So, using the Ilford paper as an example, w/o. filter the paper is ISO P 500 giving us aprox. ISO 5 for film meters. Using filters for multicontrast, the ISO P might be 200 or 100 thus giving us a meter setting of ISO 2 or 1. If it is true, well I haven't tested yet, but if someone did, I'd love to hear. Joao I would use iso 6 for most papers.I would also recomend rc for the negative.

Re: [pinhole-discussion] Scanning Color Zone Plate Negatives
Hi Tom, I can't help you with large format, all the zp work I do is 35 mm, and I am using a Nikon coolscan III, it works great, never had any problem. Joao Tom Miller wrote: Dear Gang, Does anyone on the list have experience scanning color zone plate negatives? Despite 19 years in the computer trade, I have no experience with photographic scanners, Photoshop, etc. After doing some research, it looked like the the Umax Power Look 1100 would be the best combination of features and price for my use. One of the things I hoped to do was scan color negatives to produce quick proofs and eventually finished prints. I took a couple of 4x5 zone plate color negatives (Kodak) to the local photo store to see how the scanner would handle then. One of the store's digital imaging folks spent an hour trying to scan the negs with no success, or more precisely the scans didn't produce images that looked anything like the prints I made using standard enlarger / chemical processes. His guess was that the zone plate negatives were just too wacky for the scanner; the density was poor compared to what the scanner is used to dealing with. Scanning 4x5 color negs taken with a lens camera worked great. Darn, I was looking forward to taking the plunge into digital. Also, the store is arguably the best one locally for working with professional photographers, so I don't think this was a case of operator error. Any ideas? Would a dedicated large format negative scanner have worked better that the flatbed scanner (for a similar price)? Would another brand of flatbed scanner work any better? Or is the default option of waiting for the price to drop and the quality to go up the only viable one?

Re: [pinhole-discussion] ZP image
C,a va' Guy, By contrast, my spouse is a BW person and she has turned into a ZP addict, producing effects quite similar to infra-red. Which naturally led her to test IR film with ZP. But then the combination of the two was too contrasty, so she's doing either ZP or IR. I always wanted to know how IR ZP would look like. Does she have a web site?IR films are prohibited here in Brazil (don't ask me why) so the best I can do now is digital IR with my nikon 950. Maybe in the future I'll convert it to ZP. P.S. I wonder how many people on the list do ZP together with PH. Is there a ZP Vision group?The two are both very close and yet very distant apart from an esthetic perspective, at least in my humble opinion.
