Frequently Asked Question

In cases where there is more than one suggested time/temp combination for the same film speed, this is indicated by a dot or series of dots after the ISO/ASA number. For example, you might see 400, 400., 400.. as options. Each of these is a different suggested time. The time listed without the dot is usually the standard recommended development time. The other times may differ in terms of temperature, agitation etc, so please check the notes and compare each time carefully to help determine the best one for your requirements.
