4x5 Woes: Mills, Birds And A Leak

You know, one of the most satisfying things for me these days is to spend a day at an interesting location and take six or twelve pictures with a 4x5 large format camera.

Leak

It's hard work. It means to carry a heavy-ish bag over your shoulder and a tripod with a big camera attached to its end. It means to thoroughly set up the camera, check the angles, open the shutter, stick your head under a black cloth on a sunny day with temperatures in the 90s. To focus on the focusing screen, you use a loupe that's hanging around your neck. It means to use a hand-held light meter, fish a film cassette out of your bag, load the camera, set the aperture, set the shutter speed, hope that you didn't get any of the steps out of sequence, pull out the dark slide and finally take the shot.

It's error-prone too. It means that there are at least 10 different steps in the process of making one exposure where you can mess up. Accidental double exposure? Been there, have even done a triple exposure once. Forget to set the right aperture after metering? Yep, I have my share of overexposed large format negatives.

If it's that hard work and that error-prone, then why am I doing it? The answer is simple: in the end it's one of the most fun and rewarding experiences that I've had in a long time. Nothing beats creating something with your own hands and finally holding the result of that work in your hands. Or post it online for the world to see. Much more rewarding than any digital shot has ever been.

Over time you get better. Most errors you only do once, as it hurts to lose one out of just a few pictures you'll take that day.

Last weekend I brought my trusty Grafmatic film holder system, a revolver-type 6-shooter that allows you to keep 6 shots in one magazine. Very convenient, but also heavier than normal double cassettes. Which turned into yet another source of error. I accidentally brushed the Grafmatic at the wrong angle with my arm, while the dark slide was still pulled. This resulted in a nice big splash of light pouring onto the exposed negative for a brief time. Long enough to ruin the shot. So I thought.

I ended up actually being quite happy with it. Is it because it's one of my babies? Or is there something about a perfect 4x5 picture seemingly ruined by light leaking onto it?

Let me know what you think.

Here's another picture of the same day. And another one.

Changing the Laws of Physics

IMG 0558

I just ran across another blog article that asked the question if mobile phones would take over in the long run and overthrow all other cameras because the sensor technology and the fact that you tend to have one with you all the time.

I'm not so sure for a two main reasons.

1. Control. Cameras tend to get better and better, but even the best automated decisions will not necessarily reflect your intentions.

An example: think about a backlit portrait. Without built-in intelligence, the camera's light meter will tell the camera that there's a lot of light and the image that comes out is likely to be a silhouette of a person. Most cameras nowadays will detect this and compensate for it, resulting in a well-exposed person (and most likely a slightly overexposed background). I guess in most cases that's what the person behind the camera wanted anyway, so it's okay.

But how about the times when a photographer intended to produce the silhouette picture but didn't have a way to tell the camera that that's what they wanted?

The way the current mobile phone cameras look, it's very hard for me to believe that they will get to this level of control any time soon.

2. Sensor size. Different sensor sizes result in different depths of field (DOF) and control over DOF is a very important tool for most photographers.

In-focus and out-of-focus areas in a picture are one out of a whole array of essential tools for photographers when it comes to telling a story in a picture. Focus will show or hide things, focus will help you guide the viewer's eyes through a picture.

Smaller sensors make it very hard to control DOF. Everything tends to be in focus. Bigger sensors make it easier to control DOF. A photographer can place focus where it's important. And as things look right now, mobile phone cameras are pretty unlikely to get larger camera sensors.

Even if mobile phone cameras got larger sensors, that would mean that the lenses needed to be bigger and further away from the sensors, adding bulk and size. Very unlikely.

Will newer technologies and computational photography replace the need for bigger sensors in the future?

Who knows, but at this point in time, even the Raytrix and Lytro cameras cannot do their job without a certain level of bulk, and the results are by far not where they'd need to be.

What do you think? Are we going to see DSLRs disappear any time soon?

Pimp My Cam

Some photographers pimp their cameras by buying longer or bigger lenses or by attaching super sturdy tripod accessories or harnesses. I have decided to give a bit of attention to the Chamonix and invest in a better focusing screen.

20110801 MG 0346


There's nothing wrong with the screen that came with the camera in the first place, but I've recently purchased a used 30-year-old Schneider Kreuznach 65mm f/8, which translates to a prety wide angle. The normal focal length for 4x5 is about 160 millimeters. It's a fun lens to work with, but it's also pretty dark.

In the large format world, such a wide angle means that the distance between the center of the lens and the edges of the screen are much longer than the distance between the center of the lens and the center of the screen. And that longer distance translates into an image on the focusing screen that's much darker at the edges. In addition f/8 as the widest open aperture has its challenges too. I guess everything in photography comes with a price tag.

So I did some research, and I repeatedly ended up being pointed towards Maxwell Precision Optics, a small company that among other things has specialized on focusing screens. Smooth and bright focusing screens. We're talking several stops brighter.

And today, after two weeks in German customs, the new screen finally arrived!

20110801 MG 0333

Taking the old screen off the wooden holder was only a matter of removing four screws.

20110801 MG 0334

The new screen came well protected in lots of bubble-wrap and wrapped in soft paper.

20110801 MG 0335

In addition to the screen I had ordered a protective screen with a grid and medium format markers on it. You don't want to trap dust or fluff between the two layers, or it'll annoy the hell out of you. The brush helped a lot there. It is the awesome fluff-off by Spürsinn, which I also very successfully use to take dust off negatives before scanning.

20110801 MG 0341

Finally the first tests - lookin' good!

When MEH becomes HOLY COW

Large format photography has the potential to seriously mess with ones mind. The photographer's mind and that of the audience.

For a photographer it is still the most affordable way to get spectacular resolution. The camera movements allow for compositional freedom beyond anything that is possible in smaller formats. Due to their simpler and much more symmetrical design, the image quality of the lenses is generally superb. And last but not least, the different workflow and the more thorough approach to each individual photograph generally make for more thought-out pictures.

The audience reaction to large format pictures is often a different one than to 35mm photography. Due to the higher resolution, the pictures will typically have more detail, which oddly enough tends to be true even when downsized to web resolutions. The large size of the medium (4x5" and higher) results in a very different look and depth of field. And the typical lack of falling lines tends to give even very busy pictures an amount of structure and a tidy appearance that is hard to achieve with smaller formats.

My typical reaction to the higher resolutions used to be: "meh". My impression was that at the sizes typically used on the web, it wouldn't make any difference if the picture was shot with a DSLR or if it was taken with a large format camera.

After having immersed myself in large format photography for a while now, I had to change my previous "meh" into a "HOWLY COW" though. The amount of perceived detail even at smaller resolutions tends to be spectacular.

I should have known about the detail thing from the video side of things though. A very similar effect happens when you downsize HD video footage (1920 x 1080) to SD resolution (544 × 480). The amount of perceived detail is just a lot higher than with native SD footage.

Here's my audio engineer's look at it: sound recordings are often made at a much higher bit-depth (24 bits) and higher resolution (96 kHz) than the resulting CD will ever have (16 bits / 44.1 kHz). Why? Higher perceived resolution, even at the final down-sampled stage.

My next step is to print one of these pictures at 25x50" to see the ACTUAL detail. Zooming in to tiny portions of an image to see them at a 100% pixel resolution on your screen just isn't the same.

By the way, here's a little detail from the above shot:

Die dunkle Ecke der Monster

Car Train by Chris Marquardt
Car Train (click to view and comment on flickr)

Man muss analoge Bilder auf die Schatten belichten, die Lichter finden sich dann schon von alleine. Solches hört man immer wieder, und es ist schon ein Stück weit berechtig, speziell wenn man sich im Bereich der "guten" und "normalen" Belichtung befindet.

Die wirklich spannenden Bilder finden sich allerdings oft in den Extremen.

Was, wenn man sich an die Enden heran pirscht, an die Bereiche ganz im dunkeln oder im hellen? Bereiche, die sich an anderen Stellen auch gerne mal "Zone 2" oder "Zone 9" schimpfen. Bereiche, die man als guter Fotograf gefälligst mit einem Reflektor oder einem Blitz aufzuhellen hat?

Dort begibt sich so mancher Fotograf dann in derart unbekanntere Gefilde, dass er sich nicht mehr so ganz auf die Dinge verlassen mag, die er viele Jahre lang gelernt und praktiziert hat.

Ist Schattenzeichnung wirklich so wichtig? Darf man nicht doch diese Ungewissheit ins Bild legen, die dem Betrachter Spielraum zur Erforschung gibt?

Von 15.-17. Juli 2011 halten wir in Braunschweig einen Doppelworkshop gemeinsam mit Spürsinn zu den Themen Fotografie am Ende des Lichts und Entwicklung am Ende des Lichts, in dem wir uns ganz analog und mit viel Spielfreude in die Extreme begeben.

Die dunkle Ecke im Keller, in der sich die Monster verstecken, mag beängstigen...

...spannend ist sie allemal.

Black Forest Large Format

Being confined to the studio with the Plaubel Peco for several months was a good thing as it allowed me to experiment and try out large format photography within a safe environment. But taking the Chamonix out for a first spin felt really really good too!

I took my friends Sean and Michelle for a spin in the Black Forest during their Germany vacation, and Sean brought his foldable Shen-Hao large format camera, which is virtually the same as the Chamonix.

Two guys with large format cameras in the black forest. Imagine the amount of geeking .. and eye-rolling from non-geeks ;)

Black Forest

Photographing large format is a very different way of working, and there are several things that blew my mind when I used the camera in the field and when I returned home and had a look at the pictures. One of the mind benders is the amount of freedom you have with the camera movements, also known as tilt, swing and shift. Perspectively correct pictures automatically become the norm, not the exception. You set the camera up straight, then shift to your heart's content. If the lens has a large enough image circle, that shift can be quite extensive.

And then there's the massive amount of data in these pictures. I scan my negatives on a regular Epson V600 flat bed scanner. Still, my digital files end up at about 100 megapixels and that's far from what would be possible if I cranked up the settings. My little MacBook Air 11" sure takes a bit of time to render the full size Lightroom previews.

If you're not used to this resolution, zooming in has the potential to cause a bit of mental damage to the viewer. And drooling.

Black Forest detail2

By the way, this detail is a crop from a down-sampled 50 megapixel version of the image.

But having all that said, large format is only partially about resolution. I love pictures to tell stories and that doesn't depend on resolution at all. Large format photography gives you the tools to take your time, enjoy the process, set up the pictures while thinking about their details, composing well and then taking a well-metered shot. Usually.

I have just dipped my toe into the large format waters though. There is so much more to learn, and I'm looking forward to diving more into its creative potential.

New Camera In Da House

I've been playing with large format photography for a while. Last year I bought a used German-built Plaubel monorail large format studio camera, I'm in the process of building the Marquardt International Pinhole large format camera, which is by the way moving forward and if you are on the list, you should soon get an update.

I had been missing one important piece in the puzzle: a 4x5 camera with all the required movements that I could use in the field without needing yak and two sherpas to carry it for me.

A few weeks ago I discovered the Chinese manufacturer by the not so Chinese name Chamonix. They are a small company with 8 employees and they build various foldable large format cameras, 4x5" being their smallest one.

It's the model 045N-2, it comes in at about 3 pounds without a lens and this morning one of them arrived here at my studio.

I'm going to spend some time with it to get used to the camera and to experiment. The initial impression is that it's really well built and that it is very functional for a camera of that size.

Stay tuned.

MipbwSometimes things move forward faster than expected. As it's just now happening with the Marquardt International Pinhole.

We had a meeting today and one of the outcomes was that we are going to build a run of ten cameras to see how people accept it. This will be a very special camera, not only because it creates beautiful pictures, but because each and every one of them will be a hand-made unique one-of-a-kind item.

I will not go into more detail right now because I simply can't - I know the general direction and I like it, but as you, I will have to wait for the final cameras to know what they will exactly look like.

As soon as they are finished, I will post pictures.

If you are interested in one of the first ten cameras, please send a mail to chris@internationalpinhole.com

Testing the Marquardt International Pinhole

Update: I just posted the first picture out of the MIP

Update 2: The official Marquardt International Pinhole website is now online

InternationalPinholeTest.png

Here's the first official test of the homebrew International Pinhole, complete with proper exposure times (I hope), taking reciprocity into account, even including me freezing off my fingers, as a tough photographer should do (the other choice would be to throw myself on the ground, but that was even colder).

» see how this camera was made

Some background info: aperture of the pinhole is f/200, focal length of the camera is 60mm, it accepts international (graflok) backs, which includes 4x5" film cassettes, Polaroid backs, roll film backs and more. To be installed: mechanism to hold the backs in place, soon to come.

Next up: develop and scan the pics. And post if they're any good..

The International Pinhole

Update: Here is a video shot during the first test and here is the first picture out of this camera.

» offical website

Building pinhole cameras is easy and fun. All you need is a box, some tape, aluminum foil, a pin, and joy in experimentation.

Unless you're me and your landlord is a cabinet maker. Then creating a pinhole camera might as well turn into trying to make a really awesome one.

Since I've been dabbling in large format photography I had the idea of creating a beautiful pinhole camera that would accept large format film. Not just film though, but also the according large format film cassettes, Polaroid backs and other backs, including 6x9 backs for example. All sorts of formats.

When I ran across a wonderfully made DIY pinhole holder and tripod mount, I knew that this would get me one step further, so I talked to my friend and landlord, and the other day we made a first prototype.

IMG 1169It starts with just some material, cut to the right dimensions. Here is the front wall, the sides and the top and bottom. Once finished, the camera will feature an open back that has the right dimensions to hold large format view camera backs (also known as Graflok backs). It will be able to easily fit a 4x5" film back or even a Polaroid back.


IMG 1171This is how the side walls will interface with the top and bottom pieces. This will guarantee that no light can leak into the camera and that the camera is really stable and robust.


IMG 1176Making progress detailing the parts.


IMG 1178This is the first test to see if our measurements around the international back were right. It's a perfect fit, sliding right into the slot. We still need a mechanism to fix it in place, but we've got a few fun ideas on how to allow backs of different depth, such as a Polaroid back, to fit well and be easy to attach and detach. Easier than on most monorail cameras actually.


IMG 1204Black MDF is great to work with, but it also ends up creating quite a bit of dirt. Here you see the main hole for the "lens" being drilled.


IMG 1207Test fitting of the "lens" - it's a beautiful piece of solid steel that allows to fit several different size holes, zone plates and more.


IMG 1210The outer casing is being fit together. The bottom of the camera features a beautiful and solid steel tripod mount. As you can see, the focal length on this prototype is pretty short, around 55mm. Given the size of the large format negative, this results in a pretty wide angle picture. Future models might feature longer focal lengths, even though the wide angle in conjunction with a pinhole is a lot of fun, because it doesn't know any depth-of-field issues: everything is equally in focus. Maybe we'll even find a way to do a variable focal length model. How does "first international back large format pinhole zoom camera" sound like?


IMG 1214The prototype will be held together with screws. The future models' surface will be undisturbed by screws.


IMG 1216First working model finished! Still looking for a good name for it.


IMG 1220Test fitting a tripod plate and a Polaroid back.


IMG 1221The open prototype...


IMG 1222...with a film cassette on.


IMG 1224The film cassette is a snug fit. The surface of the camera will look quite a bit different once its got the according treatment including sanding and several layers of oil, also the final model won't use screws, so this will look very different once it's in its final stage.




Still on the todo list: implement mechanism to fasten different backs to the camera (got a simple idea, more on that at another time), work on surface, make the camera a bit lighter, find a good name for it.

Yes, find a good name for it. "Large format international back pinhole camera" doesn't have enough of a ring yet.

Plaubel Peco Universal II



Here's one of the tiny little things I brought from
the Fotobörse Darmstadt. My new preccccccious...

Hm okay, one of them.

It's a German-built Plaubel Peco Universal II, it sports an international back and takes everything that fits within a size of 4x5". I've got it with a set of 4x5" and by 9x12cm cassettes. Now I'm looking for a 120 film back. Happen to have a spare one lying around? Also looking for a Polaroid back.

And yes, large format is a big journey, but it's also really exciting!

Large Format: Anarchy And Restriction

Playing With Light - 1 Okay, seasoned pros will smile at me calling 4x5" large format, as it is just the baby of the larger formats in photography. But hey, I have become super excited about it!

As you know I am right in the middle of my journey rediscovering film photography in all its glory. I don't believe I am doing this because I'm a hopeless nostalgic, trying to desperately preserve some of the long gone good old times. Far from it! It is actually much more a combination of realizing that next to the obvious weaknesses, analog photography does
have a lot of strengths that go far beyond some of the aspects of what digital can do, and that there is something wonderfully refreshing in having to work within a restricted environment.

I grew up shooting 35mm film with a Minolta X700 SLR. The 35mm format (today also known as "full frame") is the format that defined me. The 35mm format speaks a visual language that I understand very well and that I know how to handle. It feels comfortable. Sometimes almost too comfortable.

Then came medium format. 6x4.5cm, 6x6cm, 6x9cm. Later even the in-between 4x3 and 4x4cm film size. Again, a different visual language, supported by having to use a different approach in composition, workflow and by having different depth of field to work with. Initially that felt strange, and it took some time to get used to the new language and find its strengths and weaknesses. And I actually can't claim that I am completely there yet. But I feel I'm getting pretty close, and a certain level of comfort has started to set in. Still far from the too comfortable level

Then two weeks ago I attended a large format photography workshop. Two days of venturing into alien territory. And boy have I seen the light.

If you take a look at your non large-format camera, no matter if digital or analog, if compact or full-frame SLR, even at most of the medium format cameras, you will realize that they all have a clearly defined reference framework. The film plane is parallel to the lens plane, they are both on the same visual axis and the distance between film and lens is usually fixed.

On the one hand those conditions help to get to a defined state, which inevitably makes photography easier accessible to more people, on the other hand photography didn't really start out this way.

There are ways to work around those: you can use a tilt lens to leave the parallel universe (sorry, couldn't resist), moving outside the optical axis can be achieved by a shift lens, and the distance between film and lens can be changed by adding bellows in between. Or macro rings.

Enter large format photography.

The lens and the film plane are situated on two independent boards that are connected by bellows. Tilting, shifting and changing the distance are second nature to a large format camera. Total freedom. And we are not just talking about tilting and shifting the lens, you can also tilt and shift the film. Or both.

To say it in the words of a large format photographer friend: PURE ANARCHY!

But wait. A large format camera is heavy. And the film isn't on a roll, it comes in sheets that individually go into film cassettes. If you use a double-sided cassette, you have two shots per film. But you will have to reverse the cassette to take the second shot.

So doing large format photography is not only anarchy, it also is a lot of restriction. If you want to shoot outside, you will have to carry a heavy beast and a heavy tripod, just to return home with a hand full of pictures.

Restriction combined with the ultimate level of freedom. What a crazy combination! And what a refreshing one at that.

I for my part have caught the virus big time. The Fotobörse Darmstadt, one of Germany's largest trade shows for used photography gear, is less than two weeks away, and at the top of my shopping list is a 4x5" large format camera. Maybe a Toyo, maybe a Cambo, or a Plaubel, a Sinar, or maybe even a Linhof, a Horseman or a Tachihara. Or a folding Graflex.

I have the feeling that this might not be the last time you see me writing about this...
