May I suggest on the best method I have so far encounted to develop 35mm film?
If you develop film at 1:1 in D76 or other developer, can I suggest the following method of preparation? Assuming you’re using tap water as part of your developing solution and not distilled or deionized water, this method is fairly easy.
To make a 1:1 developing solution for one 35mm film, you will need 150ml of water mixed with 150ml of developer = 300ml (I know it says 290ml on the tank, but 300ml and its division by ½ to 150ml is easier to remember). This mixture of developer and water should ideally be at a temperature of 68F/20C.
Pour 150ml of developer into a measuring jug and measure its temperature. If it is under or over 68F/20C, make a separate jug of water to compensate for the difference. Example if the developer temperature is 18C, make the water to 22C, before adding 150ml of developer.
To get the water at the required temperature, put a thermometer in the empty jug and add hot and cold, either from two separate taps or a mixer tap. Don’t worry about the quantity as you can let the excess flow over the edge, just concentrate on getting the temperature you require, in this case 22c.Then pour out the excess to leave 150ml and then add to the developer, thus achieving a developer solution at 68f/20c.
And never ever, ever after the film is fixed, washed and dryed, use a squeegee. Let the film dry naturally overnight in a bathroom or airing cabinet.
If others can suggest a better method, I would like to learn about it.
