while you were out. . .

I have to say, the Zero Image 45 is finally starting to grow on me. As is the idea of doing paper negatives. Admittedly, I had gotten off to a rough start with both. Part of my difficulty with the Zero Image, was, I think, the fact that I had been using a 120 rollback with it. I was having frame overlap issues when I'd use the 6x6 mask and there were also light-leak issues when I was using the rollback with the single [25mm] frame. A bit of adhesive-backed felt placed on the metal of the roll back and used as sealer helped this a bit.

As for the paper negative process, my problem was largely figuring out how to meter the paper. I've decided to go with 6-10 ISO until I find I need to adjust that. In terms of what this means for the Zero Image exposure, I've tended to go with 60 seconds when I'm outdoors and the sky is bright but without direct sun.

Times for indoors exposures have proven to be trickier to figure out. But I decided to set the camera up in my office the other day and just let it run while I was out teaching. The first exposure I took in/of the office (see first image in the sampling below) was started at 8:10 am and ended at 11:30. The second office exposure (above) was started at 11:30 and ended at about 2:08. Pretty cool to think (as I was teaching, in fact) that I was simultaneously teaching and taking photos and doing so in two completely different locations.

Speaking of things happening while one is out and about: Chris and I decided to go to hit the snowy, snowy park again yesterday--partly so that we could walk D, and partly to enable me to finish off the 4x5 paper (see images below) that had been loaded in the holders before the order of 4x5 film arrived. We ended up crossing paths [quite literally] with someone with a Contax rangefinder (and as it turns out, lots of darkroom and photography experience) so we ended up talking to him (asking him questions, really) for quite some time. A very, very cool connection to have made!

looks like diana+ may have a little competition

Looks like there is another camera vying for my love/hate attention--the Zero Image 4x5. Yipes. When things are good between us, the images are really pretty good but most of the time, well, we just don't seem to be getting along and the images confound me. Actually, I was fine with the 50mm b/w pinhole images I took the other morning with the 6x9 roll-back mask, but when I switched to the 6x6 mask, took off the extension frame and switched to the zone plate, well, I wasn't crazy about the results. I'm still getting image overlap on some frames, so I'm not sure what the deal is with that. Next time I think I'll try the 6x4.5 mask though to see if the problem is with the smaller masks or with the 6x6 specifically. There were a couple images on this roll that I didn't even bother scanning. Part of the problem with them was that I was taking images with the sun behind the scene and it just made everything appear foggy. The coneflower image below is pretty typical of the latest batch of images: blah. (Seems I still need to get used to the wideness/wide angle of this camera--hello tripod, hello foot.)

There were actually only two images that I liked and those appear beneath the coneflower image. On the bright side, the exposures were okay--that's always a concern with the long exposures--that they'll be terrifically under-exposed. I used fuji 800 color film metered at 400 on my digital cam and then doubled most of the exposure times. Between the 800 speed film and a f/43.5 for the zone plate, exposure times were considerably shorter than they were with the last roll. The coneflower image was a 3 sec exposure and the two basement shots were each about 8 seconds if I recall correctly. It's frustrating not feeling in command of what I'm shooting (or not being able to better anticipate results) but it provides me with a challenge. If nothing else, these almost-failures leave me wanting to try something else to see if I can get this camera to do what I want it to do, what I've seen others do with it.

this just in: pinhole results

I finished and then developed this morning a test roll with the Zero Image 4x5 pinhole camera. Well, strictly speaking this was not the first roll I'd put through the camera nor was it the second, but it was the first roll of Ilford Delta 3200 speed film I put through the camera while using two extension frames, making for a 50mm focal length and f/176. It was also the first time I tried shooting with the 6x9 frame on the roll back. My initial test rolls with this camera (I did a test with the 25mm pinhole and with the 25mm zone plate) did not result in images I was at all happy with. Part of the problem with those tests was that I had selected, in one case, the wrong type of film (color with the zone plate), and in the other case, the wrong speed of film (100--not good for the b/w indoor shots). The other problem I experienced had, perhaps, to do with the 6x6 mask for the roll back. My sense was that pictures often overlapped or at the very least there were odd light leak-looking overlaps frame to frame. To ensure that I didn't experience that again, I switched to the bigger, 6x9 mask and took care to replace the roll back's metal film shield between exposures. Oh yeah--and this: I also just crossed my fingers.

Having learned the hard way that the higher speed films aren't quite as high as one might think (and with it still being the case that the whole pushing/pulling film thing still has me confounded), I metered everything at 1600 with my digital camera and doubled most times to account for reciprocity error/correction. The images appear below in the order in which I took the shots--the first 5 were taken yesterday mid-afternoon and the last three were taken this morning at about 8:45. Again, since I've not yet gotten around to mixing up a new batch of Diafine and since I really don't trust the (very old) liter of Microphen I have here, I decided to do a Rodinal stand. This allowed me to write while the film cooked. Below each image appears the time of the exposure along with the f-stop and shutter speed taken from the digital camera. Again, exposure times were at least doubled in most cases.

. . .oh yeah. and clearly, my obsession with the crutches rages on.


















f 2.7, 1/200 = 30 second exposure


















f 2.7, 1/20 = 7 minute exposure



















f 2.7, 1/10 = 15 minute exposure


















f 2.7, 1/125 = 1 minute exposure


















f 2.7, 1/125 = 1 minute exposure


















f 2.7, 1/1600 = 7 second exposure


















f 2.7, 1/1600 = 7 second exposure


















f 2.7, 1/1600 = 7 second exposure

and now for something much more labor intensive. . .

In an earlier post, I talked about how the urge to take images with the Polaroid comes upon me sometimes. Well, I've definitely been in an infrared mood of late. Actually, ever since I found the main entrance to Patapsco Valley State Park (read: the side with plenty of parking), I've been eager to go back there with my tripod and a camera (or two) loaded with infrared film. The recent Holga hang-up has delayed my plans with this. And, to be fair, the heat too has been a contributing factor--it's been soooo hot here for the past couple week. The thought of tromping around the park with all that gear, well, not particularly inviting.

Still, having done a lot of fast work lately (i.e., digital, point and shoot, polaroids), I was kinda in the mood to do some images that require more prep time, exposure time and/or patience. To my mind, infrared requires the most time and patience--at least in terms of metering, focusing, setting up the shot, making sure the i/r filter is back in place, etc. Second to that--taking images with the pinhole.

Since writing wasn't going all that swimmingly yesterday, I decided to stop that before I got too frustrated. I loaded the zero image 4x5 with ilford delta 3200 speed film and headed to the basement. (I'm seriously worried that someone will be taking the crutches so I want to make sure I get as many images as I can in the meantime.) I'm still basically winging it with this camera. I decided to use the 6x9 frame this time and I metered each shot at 1600, doubling the length of each exposure with a mind toward reciprocity error/correction. We'll see. I took 5 interior shots yesterday which leaves me with 3 frames for today. I definitely wanted to get one (or two) of the basement door in the morning light (at this point in the season, the light is best between 8-9 am). I've still not mixed a new batch of Diafine. Being so close to the move date, well, it just doesn't make sense to mix anything I'll have to move. I'm not sure then if I'll do a Rodinal stand with this film or if I'll use some HC-110. I guess it all depends on how well the writing is going. I prefer doing stand developing on writing days because I can sit here and write while the film is doing its thing. Too bad I'm so afraid of my reels getting too gummed up--I am actually kinda sorta increasingly in the mood to do some caffenol development. Hmmmm. Nah. Probably not a wise choice when I'm trying to get a handle on working with this camera and gauging proper exposure times.
