How to Develop Film: A Beginner’s Guide

Required Equipment and Materials

Before you begin the film developing process, it is important to gather all the necessary equipment and materials. Here is a list of the essential items that you will need:

  1. Film developing tank – this is where you will place your film during development.
  2. Film developing reel – this is used to load your film onto the tank.
  3. Chemicals – developer, stop bath, and fixer are the three main chemicals you will need to develop your film.
  4. Graduated cylinders – to measure your chemicals accurately.
  5. Thermometer – to ensure that the chemicals are at the correct temperature.
  6. Scissors or film cutter – to cut the film into strips for loading onto the developing reel.
  7. Timer – to keep track of the developing time.
  8. Darkroom or changing bag – to load your film onto the developing reel in complete darkness.
  9. Water – for rinsing your film after development.

It is important to have all these items ready before starting the film developing process. Missing even one of these items can ruin the entire process and leave you with unusable film. Additionally, make sure to read the instructions on all the chemicals before use and to handle them with care as they can be harmful if mishandled.

Step-by-Step Film Developing Process

Developing film may seem daunting at first, but with the right equipment and materials, it can be a simple and rewarding process. Here are the steps to follow:

  1. Load the film onto the developing reel in complete darkness either in a darkroom or changing bag.
  2. Place the loaded reel into the film developing tank.
  3. Mix the developer chemical according to the instructions, ensuring the temperature is correct.
  4. Pour the developer into the tank and agitate it for the recommended time.
  5. Pour the developer out and add the stop bath chemical to the tank. Agitate for the recommended time.
  6. Pour the stop bath out and add the fixer chemical. Agitate for the recommended time.
  7. Pour the fixer out and rinse the film with water.
  8. Hang the film to dry in a dust-free area.

It is important to follow the instructions carefully for each chemical and to agitate the tank at the recommended intervals to ensure even development. Additionally, be sure to handle the film carefully to avoid scratches or fingerprints. With practice, you will become more confident in the film developing process and be able to create your own unique prints.

Tips for Successful Film Development

Here are some tips to help you achieve successful film development:

  1. Use fresh chemicals – expired chemicals can cause inconsistent results and can ruin your film.
  2. Be consistent with the temperature – fluctuations in temperature can also lead to inconsistent results.
  3. Follow the instructions carefully – deviating from the instructions can lead to unexpected results.
  4. Agitate the tank regularly – this helps to ensure even development.
  5. Don’t over agitate – over-agitation can cause graininess or uneven development.
  6. Use a film squeegee – after rinsing, use a squeegee to remove excess water from the film to prevent water spots.
  7. Keep your workspace clean – dust and dirt can ruin your film or create blemishes on the final prints.
  8. Experiment with different films and chemicals – trying new combinations can lead to unique and interesting results.

Following these tips can help you achieve consistent and successful film development. Remember that practice makes perfect, so don’t be discouraged if your first attempts are not perfect. Keep practicing and experimenting to develop your own unique style.

Troubleshooting Common Film Developing Problems

Even with the best of intentions, sometimes problems can arise during the film developing process. Here are some common issues and their possible causes:

  1. Film won’t load onto the reel – the film may be curled, or the reel may not be loaded correctly. Try flattening the film with a film press or loading the reel more carefully.
  2. Uneven development – this can be caused by under-agitation or over-agitation, uneven temperature, or expired chemicals.
  3. Film is too dark or too light – this can be caused by incorrect exposure, incorrect dilution of chemicals, or incorrect developing time.
  4. Spots or blemishes on the film – this can be caused by dust or dirt on the film or in the developing tank.
  5. Film won’t dry – this can be caused by inadequate rinsing or insufficient drying time.

To troubleshoot these issues, start by identifying the possible causes and eliminating them one by one. It may also be helpful to keep a record of the details of each film developing session to help pinpoint any issues. Don’t be afraid to experiment with different techniques and combinations of chemicals to find what works best for you.


Developing film can be a fun and rewarding process, allowing you to have complete control over the final result. With the right equipment, materials, and techniques, you can create unique and beautiful prints. Remember to follow the instructions carefully, maintain consistency with temperature and agitation, and keep your workspace clean. Don’t be afraid to experiment with different films and chemicals to find what works best for you. And if problems arise, don’t give up – troubleshooting is part of the process, and with practice, you will become more confident and skilled.
