good to see

Years ago I worked in Aerial photography, and if I remember correctly, the camera had a vacuum back. After the roll film advanced in the camera, a vacuum was applied to suck the film flat against the hard back of the camera that had very small groves cut into it as vacuum passages, then the exposure taken, the vacuum released, then the film advanced. If you want to try and duplicate this on the cheep. if you have a glass plate holder for your camera, find the thickest flat glass that it can take, in the glass carefully drill a small hole in the center using the smallest carbide drill you can find, then lightly cut an approx. 2cm (3/4 ") sq. grid on it using a small angle grinder with the corner of a diamond cutoff wheel, intersection the hole, the groves could be as shallow as 0.2 mm, or .008 ". On the back side of the glass plate, silicone a small (4mm, 5/32 od) plastic hose with the other end connected to one of those battery operated vacuum pumps used for sucking the air out of home freezer bags.

Mat, This is a great series and this video in particular for me was cool to see. As an Aerial Photographer for the last 15 years I have shot this film as well as Color Neg, Infrared and Chrome which looks incredible in the giant roll when it’s all laid out. All from small planes with giant aerial camera systems. Mostly the Leica RC- camera series. Sadly Agfa is one of the last companies still making these films and offering them in aerial rolls as digital has all but taken over our industry now. Kodak recently stopped production of ColorNeg 2460 as late as last year. Chrome or Slide film and Infrared are long gone from production. I believe you can still get B&W in PAN80, PAN100 and PAN200 ASA. I’m an aerial photographer by trade but a LF shooter for most of my personal work and I always wanted to try shooting aerial film in my 4x5 or 8x10.

Hey Robert thanks for watching and for your perspective as an aerial photographer! If a non-aerial photographer like me can get a decent result, I'm sure there are plenty of folks out there that would find they can produce great results with this awesome film. I'd say go for it! Also, if you have a giant Aerochrome aerial photo, I'd LOVE to see one in person.

very nice

Super big thanks for this particular video Mat. I've been holding off trying that film which I first spotted when searching for 9x12cm sheet film for my Recomar 33 plate cameras. Now I think I may try it very soon based on your experimentation. The guy who is selling it on eBay is the same guy I bought my second Sakai-Toyo 1/2 plate camera from after he customized it with a 5x7 back. So I've had good experiences dealing with him in the past. I may get a box of 9x12 and 5x7 to try and if it works out I may get some for the 8x10. It's too bad that the film base was too thin for the 20th Century reel.

Thanks Gregg! I'd say it's worth a try at any size. I talked with Jeff at 20th Century Camera about what happened. We're both in agreement that it's likely because I was cutting the film shorter than a standard sheet of film, which the reels need to provide tension and not move while in the tank.

When I cut 4x5 into 2x3 sheets, I just marked in the light where I needed to have the sheet to be for the cut, then put tape there. So in the dark I would just line the sheet up with the tape notch and splice

Hey Terry, you can definitely load photo paper and should totally try it. I use photo paper to test for light leaks in holders and camera backs. Load the paper into the holder, insert into the back of the camera and remove the darkslide. Leave out for up to 1 minute then replace darkslide and process in the darkroom like any other print. If you see marks, you've got leaks.

@@MatMarrash I received the Aviphot 200 film and it too is super thin yet in the changing tent th4e 4x5 doesn’t curl noticeably so I had to waste some sheets with a wet finger to find the emulsion side that would stick. Then arrange the plastic bag with a marker for future use.

Unrelated, but I love that you use the 20th Century reel for b&w 4x5. I’ve heard of difficulties with density while using a Jobo for b&w due to its use of constant agitation. Have you had any experience or heard much? For now, I use Jobo for c41 from small format through large format, but I do hand inversion for all b&w. TIA.

@MatMarrash

4 жыл бұрын

Hey Jon, while I haven't heard of density issues with constant agitation, I've seen many Jobo practitioners use higher temps and/or dilutions of developers during constant agitation to produce more suitable contrast negative in large format. Many of these photographers were doing so for alt process printing reasons, where DMax is of critical importance. I would consider the 20th Century reel and tank inversion to be the same process-wise as any other tank inversion. Thanks for the question!

No visible scratches from the cutting process, made sure to gently lift up the plastic guard enough to start the film through the cutter. Still haven't perfected the process, but an optimal setup would include a stopper guide and a precut template to compare final film size.

As the other said great video ! But do you do someting about the thickness of the film ? The film surface can be not as the same place as a usual sheet film ,so, you can be in focus on the ground glass and out of focus when you take the photo .

@MatMarrash

4 жыл бұрын

Hey Philippe, great question. The difference in film thickness is enough that the photographer will notice it when (un)loading and processing, but not going to critically impact focus until depth of field goes < 1mm. In old forum posts, I read that some photographers were adding paper backing sheets to the film to prevent scratches; this could also help get the thickness closer to regular cut sheets.

I really liked the look of that film. I know there's no way to show the cutting process but cutting film is something I've avoided. $1/shot for 8x10 though... dang. $2 for precut isn't bad Have you ever shot any of the Ilford Harman Direct Positive Paper?

@MatMarrash

Michael your comment reminded me how much I loved/hated working with this film. When all goes right, it's one of the best films for the money, but the thin, easy-to-scratch nature of it makes it tricky at best. Worked a little with Harman DPP, but with the rising cost of paper, I think I'll stick to rc paper negatives.

Hi Mat, great video! I'm thinking about using the aviphot and developing it in the jobodrum 4531 (rotation developing). How do you think, it is possible? I would like to avoid developing in trays. Greetings from Poland!

Hey John it very well could be. There wasn't much documentation that came with this roll film. If it is nearly 20 years past expiration, it's one of the lowest base-fog films I've ever used!

Here in the UK the 4X5 is not affordable any longer ( forget the 5X7 and 8X10 ), not for me anyway. 50 sheets of 4X5 Kodak Tmax 400 ( value size !!! ) £213.00 or $267.00. That is just over $5.20 a sheet. Not so long ago I used to buy the same pack for around £52.00. I think Kodak is having a laugh as we say in the UK. Ilford HP5+ is roughly 1/2 of the price of Kodak but this is still very expensive for a hobbyist or just for experimenting. I find this situation rather puzzling as up to 2015 the price of a roll of 120 film was actually a lot cheaper than a roll of 36 EXP 135 but now they are either the same or more expensive for some reason. The emulsion area of 4 sheets 4X5 film is actually smaller than 36 exp of 135 so how on earth they have come to such pricing is anyone's guess. Rollei is now rolling up the last remaining stock of the Agfa Aviphot as Rollei Retro 80s in 36 EXP 135. it does work well with compensating developers and Pyros.

Once these stocks have gone the supply cease to exist. Just have a look and see how many emulsions marketed as ' new emulsions ' are no longer available.
