B&W slides and transparencies

We love monochrome – always have, always will.

We output hundreds and hundreds of monochrome 35mm, 6x7cm and 5″x4″ transparencies every year (diapositives or dias to our continental friends) and, perhaps surprisingly, it is mostly done on regular colour film alongside all the colour slides. It doesn’t actually make any difference to us whether your images are black & white or colour. We take great care over the neutrality of our output – this is important for colour slides but even more important for monochrome; there is nothing worse than green-tinted black & white!

However, we do also produce true monochrome slides using reversal-processed silver halide film, and we think we are the only company outside of the US producing them. The 35mm slides do have a premium price but are for the purists and image quality lovers who seek that silky-smooth silver image that was once provided by AGFA Scala film of yesteryear and now made on Adox Scala film of today (the only film suitable for highest quality slides, due to it’s clear base – all other films have a grey tinted base). They are ideal for archival and endurance projection too, due to their silver, not dye, image.

You don’t need you do anything special to your files, work on your screen just the same as colour images. The easiest conversion is to simply desaturate your image and save. Those who are a bit more particular will use the IMAGE > ADJUSTMENTS > BLACK & WHITE in Photoshop and play around with the colour sliders to make a more visually pleasing conversion from colour to monochrome. There are some great plugins too – NIK’s “Silver Efex Pro” especially.

Provide your files in the following format:
RGB JPEG (saved as level 10 or ‘high’ quality) – definitely don’t use CMYK or, perhaps counter-intuitively, monochrome formats.
sRGB profile (but other profiles are fine)


Output image dimensions

35mm – 4096px x 2732px
6x7cm – 8192px x 6702px
5″x4″ – 8192px x 6732px

The above are the exact dimensions we output at. There isn’t much point in up-scaling low resolution images to these sizes as you won’t gain any quality, but if you are shooting at higher resolutions than indicated then you can down-size, if you wish.
