Introduction:

Darkroom photographers who seek consistency, reliability, and excellent print quality understand the importance of a dependable paper developer. FOMATOL LQN 250ml is a specially formulated liquid concentrate black and white paper developer created by Foma Bohemia — a trusted name in analog photography since 1921.

Designed for normal-working development, this developer is ideal for both manual tray processing and automatic developing machines. Its precise chemical balance and flexible dilution options make it a perfect match for all types of B&W photographic printing papers, whether you’re working with resin-coated (RC) or fiber-based (FB) varieties.


What is FOMATOL LQN 250ml?

FOMATOL LQN 250ml is a high-quality liquid paper developer for black and white photographic prints. It comes in a ready-to-dilute format and offers a balanced tonal response, normal working contrast, and clean highlight-to-shadow transitions.

This paper developer ensures:

  • Excellent tonal reproduction

  • High image stability

  • Uniform development across the paper surface

Whether you’re printing contact sheets or exhibition-grade fine art prints, this developer delivers results that are sharp, neutral, and consistent.


Key Benefits of FOMATOL LQN 250ml

Here’s why photographers worldwide trust FOMATOL LQN 250ml for their darkroom workflow:

🔹 1. Liquid Convenience

Unlike powder-based paper developers that require full dissolution and careful handling, this developer comes as a liquid concentrate — reducing prep time and mess. Just dilute with water and pour it into your tray or processor.

🔹 2. Dual Use – Manual & Automatic

One of the most flexible features of FOMATOL LQN  is its compatibility with both manual darkroom processing and automatic processing machines. Ideal for labs, schools, or photographers with rotary drum processors.

🔹 3. Consistent Output

When diluted correctly, FOMATOL LQN 250ml provides even development and normal contrast. It’s engineered to handle a wide range of exposure conditions and paper types without color casts or uneven tones.

🔹 4. Flexible Dilution

You can dilute FOMATOL LQN 250ml based on your processing method:

  • 1:7 dilution – For manual tray development

  • 1:4 dilution – For automatic processing (higher replenishment rate)

This flexibility makes it ideal for photographers who work in different environments.


How Much Can You Develop?

From one bottle of FOMATOL LQN 250ml, you can produce enough working solution to develop dozens of black and white prints, depending on paper size and dilution ratio. For example:

  • At 1:7 dilution, you can produce approximately 2 liters of working solution.

  • This is typically enough to process around 40 to 50 prints (8×10″), depending on usage and agitation.

If you’re working with larger paper sizes or heavier FB papers, you may get fewer prints, but the quality remains outstanding.


Applications of FOMATOL LQN 250ml

FOMATOL LQN 250ml is ideal for:

  • Fine art silver gelatin printing
