The ratio of the two exposures controls the resulting contrast of the paper. The system is currently available customised for several popular enlargerswith more to come. For existing users, the latest firmware is available for download here. Heiland has recently introduced a range of LED cold light sources which interface directly to the Splitgrade system and which can be adapted to many different enlargers from the Leitz V35 through 6x9, 5x4, 7x5 to 10x8.

The "Comfort" control interface adds a new level of convenience to the operation of the system and can be added to existing controllers as an option.

For convenience, we have summarised the differences between this system and our Exposure Meters here. Several influences characterise a black and white photograph. Before taking a shot of the subject the photographer recognises the subject contrast and determines the exposure and development of the film in order to reproduce the subject.

The resulting negative will have a contrast range ideally in the region of 1.

Also, the actual contrast produced by any given filter will be dependent on the characteristics of the paper in use. When using infinite grade systems colour or VC heads the major disadvantage is that the range of possible grades is not linear.

The light sources are not anymore expensive as the older stuff was 20 years back. I have been fortunate to find the older technology both "hot" and "cold"one is basically a light bulb similar to a slide projector, the "cold light" is something like a fluorescent tube which by the way these cold lights require a heater to work properly The modern LED sources put everything else in second place still perfectly usable 2nd place.

Heiland Splitgrade LED Module for Leica Focomat V35 AF Long ago people used the darkroom, not because they liked the idea, but because it was the only cost-effective way to have their negatives printed on a decent size of paper.

You were photographer, not a darkroom expert and with the exception of a handful of fine-art printers and zone-system enthusiasts, the darkroom was a place to be avoided. There has always been a core of photographers who wanted to have mastery over every step of the photographic process. Since the full digitization of photography from capture to distribution, every one can be a master of the photographic universe. From a technical standpoint a fine darkroom print and a fine inkjet print may be equals, and when large-sized prints are required say significantly larger than A4 the digital workflow wins hands-down because of the degradation effect of light scattering in the silver-halide emulsion.

From a qualitative and may I add an emotional view the silver-halide print has a visual impact that the digital print simply lacks. It is not by accident that Nik with Silver Efex and DxO with Filmpack have two programs that emulate the quality of the subtle shades of grey at least much more than fifty!

Darkroom prints from standard 35 mm Leica negatives are limited to a size of A4 and at most A3 to have strong visual impact and high technical quality excellent sharpness impression also known as acutance and a just perceptible grain pattern for three-dimensional reproduction of fine textural detail.

One of the main rules for Leica pictures is the optimization of the negative area, not wasting the edges of the image. The proportion of the negative however is difficult to match with theand proportion of many printing papers.

Finding the exact exposure time to get maximum black without clogging the shadows, and selecting the correct paper gradation for a given negative density range was and is a time consuming experience and one that has to be repeated for every size of enlargement and paper choice. Most papers used in the darkroom are of the variable contrast type. VC paper is composed of two different emulsion types in one layer, one sensitive to green light soft gradation and one sensitive to blue light hard gradation.

With a yellow and a magenta filter or a mix of both we expose one or both emulsion types for a certain time. The yellow filter blocks out the blue light and so exposes the green sensitive layer. The magenta filter blocks out the green light and so the blue sensitive layer is activated. All VC modules use a light box to mix the blue and green colors for one exposure.

The specific mix corresponds to the grade 0,1, 2, 3, 4 and 5. The Heiland Splitgrade system has been designed to take the guesswork out of the darkroom practice. The designers call this device a grade management system. The core of the system consists of two parts. One is the VC module which will replace the existing VC module of the enlarger. The module has two separate filters, one for yellow and one for magenta, that are placed into the enlarger light. The paper then is exposed twice, once for the yellow filter and once for the magenta filter, the relative proportions being computed by the system and corresponding to the grade selected.Our new search experience requires JavaScript to be enabled.
