Rinse or use a stop bath after the developer Using a water rinse before the blix will help the solution keep longer. In a pinch, the cold water from your tap will have fewer contaminants in solution than hot water, since cold water comes straight from the source. The blix is relatively stable in comparison. The developer is the most sensitive and is the main chemical that affects the quality of results. If you’re trying to save money, you can use distilled water for the developer only. But distilled or demineralized will always help keep the solution fresh - especially if you top the bottle up to the top after every developing cycle since a little is usually lost. The solutions are rated to last 1 month assuming the use of tap water. Using distilled or demineralized water helps to reduce the number of contaminants that can ruin the solution over time. Using distilled water will help keep your film developer lasting longer. If you can’t get them from a brewery or need faster delivery, you can find this same type of bottle on Amazon here. Read more about these storage bottles in this article about making developers and solutions last as long as possible. And the brown color means sunlight won’t be able to penetrate through the solution. The bottles also typically have cool designs, so if you get them from multiple breweries, you’ll have an easy time differentiating the bottles during development. Wider tops will allow you to pour the solution faster, which can help ensure your negatives develop evenly. Not only will you get to take home some excellent beers, but these bottles are designed to hold the beer fresh for as long as possible. The type of glass bottles I recommend are wide-top growler bottles from your local brewery. Make sure to always fill it to the very top of the rim - even if you have to use tap water (distilled is better), it’ll still be better for the developer than allowing air to oxidize the solution and render it useless. These will ensure that no oxygen gets into the developer solution so that it doesn’t break down over time. Glass bottles are the least porous and have the best possible seal when full. Store the chemicals in air-tight glass bottles Every film used increases the colour developing time by 2%. I make markings on the tape to show how many films have been developed with this solution. Color developer stored in a local brewer’s growler bottle. Using these, you’ll be able to get more than the rated value out of any color film home developing kit, including Cinestill CS41, Arista, Unicolor, Flic Film (with separate bleach and fix), or Tetanal kits in both liquid or powder formats. Here are my top 6 tips for extending the capacity of color-developing kits. I’ve developed hundreds of rolls over the years, and have extensive experience pushing these kits to their limits. If you’re like me, you’ll want to get the most film developed for the money. For example, the rated capacity of the popular Cinestill CS41 Quart (1L) kit is only 8 rolls. If you’ve ever bought a color film developing kit, one of the first things you’ll notice is that the rated capacity may be lower than you’d like.
