LVT Film Negatives: Digital to Film, London

"The negative is the score, the print is the performance."

Your digital file becomes a film negative.

Continuous tone, no dot pattern, no pixel structure. Just silver on film, exactly as if it had come from a camera. From there, the darkroom does the rest.

We deliver on 4×5" and 8×10" sheet film, in colour negative, black and white, and colour positive. Our colour workflow is custom-profiled to modern film stocks. What you see on a calibrated screen is what is recorded on the negative. Enlargements to 10× the negative size are routine.

Photographers bring us digital originals, restored archival scans, and slide collections that need faithful duplication. The file goes back as a film negative. The rest happens in the darkroom.

FAQ

Why use a film negative rather than printing digitally?

A digital print, whether inkjet, Lambda, or Lightjet, is the endpoint. A film negative is an intermediate: it can be printed an unlimited number of times, by any printer, on any paper, in any darkroom, anywhere in the world. The negative is the archive. Each print made from it is a unique object, shaped by the printer's hand and the materials they choose. For photographers committed to the darkroom, there is no substitute.

What is a digital film negative?

A digital film negative is a photographic sheet film negative made directly from a digital file. Using Kodak's Light Valve Technology (LVT) film recorder, your image is written pixel-by-pixel onto photographic film at high resolution, producing a continuous-tone negative identical in character to one exposed in a camera. It can be enlarged in a darkroom, used for contact printing, or employed in any traditional or alternative process.

What is LVT, and why does it matter?

LVT stands for Light Valve Technology. The Kodak LVT film recorder is the highest-resolution film recording technology available. It exposes film directly from a digital file with no intermediate dot pattern or pixel grid. The result is a genuinely continuous-tone negative: smooth tonal gradation from shadow to highlight, with no aliasing, no screen pattern, and no compromise in the darkroom. It is the technology used by major photographers and institutions for archival and exhibition work. Our LVT recorders are among a handful left worldwide in daily use.

What is meant by digital to silver?

Digital to silver refers to any process that converts a digital file into a traditional silver halide photographic material. LVT film recording is the highest-quality digital to silver process available, producing results indistinguishable from an in-camera original.

What film stocks do you write to?

Kodak Portra 160 for colour negative, Ilford Delta 100 for black and white, and Kodak Ektachrome 100 for colour positive. Each stock is individually profiled to our machine and development process.

What sizes do you offer?

4×5" and 8×10" sheet film. Both sizes support enlargements up to 10× the negative dimensions, giving you prints up to approximately 40×50" from a 4×5 negative, and 80×100" from 8×10. 35mm frames can be ganged onto 4×5.

What resolution does my file need to be?

The LVT writes at 80 pixels per millimetre (2032dpi). Do not resize or interpolate your file to this number. Supply your native file at its native resolution. As a guide: a 50 megapixel camera file is ideal for 4×5 output. For 8×10, you need a file with a long edge of at least 10,000 pixels, typically from a high-resolution scan or 100mp digital back. If your file is between sizes, we will advise on the best output option. For scanning existing film originals to the right specification, see our scanning service.

How does LVT resolution compare to megapixels?

The LVT records approximately 83 megapixels onto a 4×5 negative, and approximately 330 megapixels onto an 8×10. Nearly all modern digital cameras produce files that fit comfortably onto 4×5 film.

Will the negative match what I see on my screen?

Not exactly. A screen emits light; a print reflects it. They are physically different objects and will never be identical. What our colour profiling ensures is that the negative is faithful to your file: the tonal relationships and colour balance you have established are recorded accurately onto film. What the darkroom makes of that negative is its own conversation, shaped by paper, chemistry, and the printer's hand. That said, transparencies and E6 match a calibrated screen extremely well as they are emissive by nature like the screen.

What colour settings should my file be in?

Adobe RGB colour space. Grade the image as you intend it to print, but do not crush the blacks. Avoid large areas of RGB 0,0,0, as the film requires tonal headroom at both ends of the scale. Do not apply heavy sharpening. Supply as a TIFF where possible; 16-bit if your workflow supports it.

Do I need to invert or resize my file before sending?

No. Send your image as a positive, in its correct orientation, at its native resolution. We handle all file preparation and sizing required for output.

Do you develop the negative?

Yes. The negative is developed with our partner lab, Labyrinth Photographic. You receive a processed negative, ready for printing.

How do I receive the negative?

You can collect in person from our London studio, or we can post or courier the negative to you anywhere in the world. We can also arrange darkroom printing or scanning directly if you would prefer not to handle the negative yourself.

Can you print from the negative as well?

Yes. If you would like us to arrange silver gelatin or colour RA-4 darkroom printing from your negative, contact us to discuss. This can be arranged as part of the same order.

How long does it take?

For orders given with sufficient notice, one to two working days for medium-sized jobs. For single frames or urgent requests, allow three or more working days. Contact us before sending for time-sensitive work and we will be direct about availability.

Can multiple images be output on a single sheet?

Yes. For smaller output sizes, multiple images can be ganged onto a single sheet, which reduces cost. Tell us what you are working with and we will advise on the most efficient layout.

Can I use LVT negatives for platinum, palladium, cyanotype or other alternative processes?

Yes. The continuous-tone quality of LVT negatives makes them well suited to contact printing in alternative processes. There is no dot structure to interfere with UV-sensitive emulsions, unlike inkjet negatives. We regularly produce negatives for platinum/palladium, cyanotype, gum bichromate and salted paper printing.

Can LVT negatives be made from damaged or deteriorating originals?

Yes. A deteriorating glass plate, nitrate negative or acetate original can be digitised, restored in post-production, and output as a new LVT negative on stable polyester-base film. The result is a printable negative. This is standard practice in archival and conservation work. See our scanning service for digitisation of fragile originals.

Who uses this service?

Fine art photographers printing in silver gelatin or alternative processes. Photographers who shoot digitally and want the qualities only a darkroom print can offer. Artists and estates restoring or re-printing archival negatives. Museums, archives, and conservation departments requiring archival film output from digitised collections. Anyone who needs a faithful film intermediate from a digital master.

Can you duplicate slides or transparencies?

Yes. We write to colour positive film, which allows accurate duplication of existing slides. When we scan the original, minor imperfections or colour imbalances can be corrected before output, meaning the duplicate can be more accurate than a deteriorating original. E6 positive output is available by enquiry.

Is this available to clients outside London?

Yes. Files are submitted digitally and negatives are posted or couriered worldwide. A significant portion of our work comes from outside the UK. See our ordering page for international shipping details.
