Large format photography means working on sheet film, nowadays the common initial size is 4×5″. Beyond that even bigger dimensions are available: 13×18 cm, 5×7″, 18×24 cm, 8×10″ and further sizes. All of them are usually sold in lightproof boxes. Instead of loading a camera with ready for use 35 mm or roll film you first need to insert sheet film into an appropriate sheet film holder. A sheet film holder looks like a flat black cartridge and has two dark slides (each on one side) which are separated by a centered partition. Thus it can comprise two sheets of film.
The crucial factor is to load the film holders in absolute darkness in order to avoid an unexpected exposure. Therefore a darkroom (without any lighting), a mobile changing room or changing bag can be used. Handling the film material in the dark is facilitated by specific notches that are cut off one short side. On the one hand these notches mark the precise film type on the other hand they indicate on which side the emulsion is affixed.

Remember to accomplish the loading in entire darkness. The procedure is the same with larger formats than 4×5″. When having inserted the film holder into the camera, don’t forget to remove the dark slide before exposing and to replace it again afterwards.

Now, have fun shooting large format film!

It has been half a year now since it conquered our pinhole-loving photographer hearts by storm. Our curiosity had already been piqued last autumn when HARMAN technology announced the HARMAN TiTAN Pinhole Camera (for 4×5″ sheet film) developed in collaboration with Walker Cameras.

A lightweight camera to go

Due to its light and compact construction (less than 250 g / 9 oz.) the camera is made to be taken around. The additional equipment (the inevitable tripod and a sufficient amount of sheet film holders) may weigh a little more, yet we have spent many weekends hiking in the Alps or strolling through various cities over the past months without being sorry about it.

The camera

The pinhole camera construction is rather simple; technically speaking it consists of four parts:

• body with two tripod mounts, two spirit levels, accessory shoe, film holder slot and two cone clips
• cone 72 mm / 2.8″ (attached to the body by cone clips)
• pinhole f206 (attached to the cone by clockwise rotation)
• pinhole cover (film is being exposed by opening and closing the cap)

The injection moulded body made of ABS plastic is covered with an anti-slip coating that adds to the high-value appearance. Furthermore, all metal attachments are manufactured from stainless steel, which allows the camera to be used under raw weather conditions as well. The cone is not matt-finished on the inside, however there’s no need to fear undesired reflections. The camera’s overall dimension is about 16 cm x 14.5 cm x 9.3 cm / 6.3″ x 5.7″ x 3.7″, thus it will definitely find its place in every baggage.

What’s in the box?

The ILFORD labelled cardboard box (HARMAN technology Ltd succeeded ILFORD Imaging UK Ltd in 2005) contains 10 sheets of each HARMAN DIRECT POSITIVE FB paper, ILFORD MULTIGRADE IV RC paper and ILFORD DELTA 100 professional film as well as a pinhole exposure calculator. The “ILFORD Pinhole Photography Kit” instruction manual is provided in four languages. HARMAN also anticipates all “unboxing videos” on YouTube with its own detailed contribution.

Working with the camera

Handling the camera really is quite intuitive. Once the camera has been assembled and the quick release plate screwed tightly into one of the tripod mounts you can get started. It might be useful to own a second plate if you vary upright and horizontal format very often and do not want to spend your time screwing plates on and off – and due to instability do not want to rotate the tripod head by 90°. When the HARMAN TiTAN is mounted on the tripod and the sheet film holder is slid into the film holder slot the camera is ready to expose.
The exposure time can be determined with the enclosed exposure calculator (either by the means of a light meter or by estimating light values referring to the calculator symbols). Of course, the reciprocity failure of the specific film or paper type must be considered additionally. That is why we reverted to the collection of long exposure compensation charts (PDF) which we just extended by some more films.

As the pinhole cover fits very tightly to the pinhole (that’s good in some respects because the cover will not fall off accidentally), we have found it helpful to loosen it a little bit (only as far as the cap is still absolutely lightproof) in order not to shake the camera when finally opening the cover for the exposure. One last thing concerning the pinhole cover: do not remove or replace it by rotation as you might screw off the whole pinhole. Either way, it is necessary to remove the dark slide of the film holder prior to the cap. During the exposure time the cap can be dangling on its string, just be careful with strong breezes blowing it into your image area. Eventually the 72 mm / 2.8″ cone has quite a nice wide angle equivalent to 20 mm / 0.8″ on 35 mm format. Owning a view finder with the appropriate focal length to put it right into the accessory shoe is doubtlessly of great advantage when sighting subjects for a photograph.

Over hill and dale

That is enough for the technical part. Now, what can you capture with the HARMAN TiTAN Pinhole Camera? We took it with us hiking through the Alps until heights of 1600 m / 5250 ft, faced the Rhine Falls together, strolled about the picturesque old town of Bamberg, visited the Munich spring festival (which is said to be the small Oktoberfest) and the Chinesischer Turm (“Chinese Tower”) in the English Garden. During all these excursions the camera told us that it likes subjects with every kind of movement (rushing waterfalls, spinning carrousels) and sometimes even being dazzled by the sunlight (but only for a short time, otherwise the film footage might get sunburnt). All the time it was firmly positioned on a compact travel tripod. Throughout our trips we were busy feeding it monochrome negative, colour negative and slide film. In return we were rewarded with wonderfully characteristic photographs.

Unlike us, even in draughty places with cold winds blowing the camera did not shiver (perhaps that is due to its aerodynamic shape), so all pictures turned out to be sharp.
Presumably as sharp as a pinhole photograph can become (it might be very difficult to find a camera obscura that produces sharper images on 4×5″), likewise a soft vignetting spreads out from the image margin. Astonishingly when photographing the sun directly there are only few sunbeams visible. For these reasons we guess that Walker Cameras knows how to manufacture very precise and smooth pinholes.

A greater variety

Apart from the 72 mm / 2.8″ focal length cone, new cones with 110 mm / 4.3″ and 150 mm / 5.9″ have been announced and are already available in the UK. While the 110 mm cone is featured with a f250 pinhole, the 150 mm cone holds the aperture f288. (Without exception all three cones and pinholes create the best possible sharpness according to Lord Rayleigh’s formula.) Furthermore a blank pinhole adapter is available for all those who would like to waive perfect sharpness and wish for more distinctive pictures (with irregular vignetting or blurrier detail). As all parts of the HARMAN TiTAN Pinhole Camera are interchangeable there is a multitude of scopes for design by now.
In March a prototype of a 8×10″ pinhole camera was shown for the first time. We are curious to get to know the growing HARMAN TiTAN Pinhole family.

By the way, the current kit containing the 72 mm / 2.8″ cone is priced at about £165 (Amazon UK) respectively $230 (Amazon US) or €240. And there is no need to hide behind the wooden competitor particularly in view of the fact that the HARMAN TiTAN is thoroughly British and even brings along some sheets of film and paper.

Ready for any venture

We are glad to have found such a special, forbearing and solid travel mate and are already looking forward to exploring further possibilities with this amazing camera.

We are proud to present the new English version of Überlicht. At our German blog ueberlicht.de we have been blogging about photography for almost two years now. During that time we realized, that a lot of posts are read by many people from around the world with the help of google translate. For that reason we decided to launch Ueberlicht.com and provide you with (hopefully more correct) English translations of the most interesting articles. If you like to see a specific post translated, please let us know!

We are ready to start and will present the first camera review within the next few days. Have fun reading!
