Kentmere Pan 100
A comparison with Ilford FP4 Plus – both developed in SPUR Omega X
This comparison is intended to illustrate how two traditional cubic-grain black-and-white films – Kentmere Pan 100 and Ilford FP4 Plus – respond to identical development in SPUR Omega X, highlighting the inherent characteristics of each emulsion under controlled conditions. Both photographs were taken within a short time interval using the same lens and camera setup, then developed in SPUR Omega X according to the manufacturer’s recommended parameters for each film. The negatives were scanned and converted without any additional digital correction, tonal adjustment, or sharpening.
Kentmere Pan 100
Grain Structure and Homogeneity
In SPUR Omega X, the Kentmere Pan 100 reveals a balanced and evenly distributed grain structure, resulting in a calm and harmonious image impression without any loss of sharpness or texture. The developer visibly smooths the grain pattern and promotes a homogeneous rendering of fine tonal values. Compared to the FP4 Plus, the grain appears slightly coarser and more pronounced, particularly in water areas. In the mid-gray zones, small grain clusters add a distinctive texture that gives the image a strong documentary character.
Sharpness and Microcontrast
The rock formations in the Kentmere negatives appear more crisply contoured, with steeper transitions between light and shadow. This produces a high-contrast, almost graphic visual quality that enhances edge definition and emphasizes structure.
Tonality and Density Distribution
Kentmere Pan 100 tends to show a steeper tonal curve: shadows and highlights are more distinctly separated, while midtones appear slightly compressed. The overall contrast is stronger, lending the image a bold, energetic look.
Overall Impression
Kentmere Pan 100 in SPUR Omega X produces powerful, texture-rich negatives with a clearly defined grain and distinctive character. The developer improves tonal smoothness and surface uniformity, yet preserves the film’s inherent grit and expressive strength.
Ilford FP4 Plus
Grain Structure and Homogeneity
The FP4 Plus exhibits a finer and more consistent grain structure, with smoother tonal transitions in equal-density areas such as sky or water surfaces. Its classic cubic emulsion delivers a naturally harmonious texture that SPUR Omega X further refines. The developer demonstrates its strength here by combining high edge sharpness with exceptional grain uniformity and tonal precision.
Sharpness and Microcontrast
FP4 Plus negatives display softer yet well-defined tonal transitions. Fine textures within the rocks are rendered with great subtlety and tonal depth. The microcontrast appears more refined – achieved not through increased hardness, but through precisely graduated tonal separation.
Tonality and Density Distribution
The FP4 Plus shows a wider tonal range in the mid-density areas – characteristic of this film. The resulting image has a more balanced, natural tonal progression, particularly visible in continuous transitions such as the movement of waves or gradual shading in stone textures.
Overall Impression
Ilford FP4 Plus in SPUR Omega X offers fine grain, excellent tonal differentiation, and a refined balance between detail, smoothness, and contrast. The combination produces negatives with exceptional tonal depth and a calm, natural aesthetic that retains the analog character of the emulsion.
Conclusion
SPUR Omega X brings out the full potential of both classic emulsions, maximizing detail rendition and tonal depth while respecting the individual character of each film. With Kentmere Pan 100, the developer improves the uniformity of homogeneous image areas and subtly refines the appearance of coarser grain. In the case of Ilford FP4 Plus, it enhances the film’s naturally refined tonal gradation, achieving an exceptional balance between sharpness, smoothness, and tonal harmony.
Both negatives demonstrate that SPUR Omega X is designed for natural, differentiated rendering with remarkable surface homogeneity — even when used with more affordable film stocks such as Kentmere Pan 100.
