Another eTone option combines a complete developing tank with two spiral reels and a film changing bag for safer, spill-free processing. This kit emphasizes versatility for 120 and 135 format films, plus essential accessories like a timer, measuring cups, and loupe magnifiers. It supports simultaneous or independent channel timing for precise development cycles, making it suitable for students and hobbyists alike.
eTone Darkroom Developing Equipment Kit For 8×10 to 5×7 Photo Paper

While focused on larger formats, this kit includes a set of three developing trays, storage bottles, safelight, and measuring tools that translate well to 8×10 and smaller B&W processes. It’s a practical secondary option for photographers expanding their darkroom workflow to include paper development alongside film processing, using compatible bottles and clamps for clean chemical handling and streamlined organization.
YCCLDIPL Darkroom Kit For 120 135 35mm Colour B&W Film

This kit emphasizes a two-spiral self-feed system that ensures uniform chemical flow through the tank, capable of handling two 135/35mm rolls or one 120 roll per cycle. It includes a robust accessory package—gloves, loupe, sifters, measuring tools, and a two-litre storage bottle—to support comprehensive darkroom workflows. Note the tank’s red-cap seal and upside-down caution, which users should adapt to in practice.
Kodak XTOL Black & White Film Developer

Kodak XTOL is a powder-based developer designed for B&W films, offering high image quality with ease of mixing at room temperature. It is known for broad temperature tolerance and stable performance across dilutions, making it a reliable option for various negative materials and processing preferences. This product is widely used for fine grain and extended tonal control in black-and-white photography.
Buying Guide
Key considerations when choosing a black-and-white film developing kit:
- Format compatibility: Confirm whether the kit accommodates 120, 135, and 35mm formats, or focuses on specific sizes. If you shoot multiple formats, seek multi-format tanks and reels.
- Tank and reel quality: Look for durable, unbreakable plastics, corrosion resistance, and reels that fit standard tanks (Paterson-compatible or similar). Reels should rotate smoothly for even development.
- Number of channels on the timer: A three-channel timer supports independent development steps or parallel processing, which improves workflow efficiency for larger batches.
- Accessory variety: A comprehensive kit (measuring cups, cylinders, safelight, loupe, changing bag) reduces the need for additional purchases and helps maintain a clean work environment.
- Safety and compatibility: Ensure that gloves, safelights, and chemical storage solutions are suitable for film processing chemicals and compliant with local handling guidelines.
- Chemical compatibility: If using color (C-41) chemistry, verify whether the kit’s chemistry components are suitable for color negative films in addition to B&W; some kits are optimized for B&W only, while others support both.
- Budget and expandability: Consider kits that allow you to upgrade components (tanks, reels, measuring tools) as your skills grow, without replacing the entire system.
- Temperature control: Temperature stability affects development results. Look for integrated thermometers and instructions that align with your target temperatures for B&W processing.
- Maintenance: Easy-to-clean parts and dishwasher-safe or hand-washable components simplify routine upkeep and prolong system life.
When evaluating options, prioritize kits that provide a complete, cohesive workflow for both film handling and chemical management. For enthusiasts focusing on black-and-white aesthetics, a reliable tank system paired with a precise timer and quality measuring tools often yields the most consistent tonal control and grain management.
