Frequently Asked Question
How do I use the chart?
Last Updated 4 years ago
Whilst every effort has been made to ensure the accuracy of the data contained in the Massive Dev Chart, it is always advisable to run some tests of your own before developing important work. Please use these times as starting points only. Data like this should always be treated as a guideline because of the tremendous number of variables involved. One combination might work well in flat lighting, but be unsuitable for high-contrast scenes.
Times: All times listed are in minutes using decimal format. For example: 8.25 = 8 mins, 15 secs.
Agitation: Wherever possible times have been listed which rely on the standard technique of 30-60 seconds continuous agitation after immersion, followed by 5-10 seconds (three inversions) per minute thereafter.
Rotary Processors: Times marked for rotary processors can be increased by 15% to provide a starting point for hand held tanks. Equally, you can reduce all times not listed as requiring continuous agitation by 15% to provide starting points for use with Jobo or other rotary processors.
Sheet Film: Times listed for sheet film are intended to refer to tray development. As not all manufacturers list specific development procedures, some times require adjustment. If the time listed is the same as that for 35mm or roll film you may want to reduce this by approximately 15% when using continuous agitation or a rotary processor.
Sources: Although many of the times listed on the chart are supplied by the manufacturers, quite a few of them are independent submissions. As a general rule, we have listed the time published by the film manufacturer, and where this data is unavailable we have used the time published by the developer manufacturer. Where there is significant information suggesting that a published time is inaccurate, we have replaced this time with third-party data.
