Photography: What if there is no fixing solution?

Of course, clear water can't. The function of fixing solution is to neutralize the alkaline chemical components in developing solution and stop the development process of photos, which can't be done by clean water. The commonly used fixing solution is "baking soda+water", commonly known as "Haibo", which is a commonly used chemical raw material and easy to buy.

If the film is not cleaned with fixing solution after development, it will cause the film to develop too thick.
