The new f-Stop timer from Darkroom Automation http://www.darkroomautomation.com/da-main.htm With these features: o 300 steps of non-volatile memory - Room to keep the sequences for your most popular prints in memory - ready for whenever you need them and with no re- programming - Room to experiment when you design a print's exposure sequence; keep several approaches in memory at the same time o Easy memory programming - The timer's prompting display, menus and consistent operation make programming easy - On-the fly programming, no special programming mode - Insert, delete and modify steps at any time o Split filter printing - High and low contrast channels; the timer prompts for filter changes - Separate control of exposure and contrast - Either high or low contrast can be exposed first for the base exposure - Extensive dodge and burn support . Convenient optional combined dodge & burn sequence for prints made at one contrast: only one sequence to edit and modify . Separate dodge and burn sequences for prints made with varying dodge and burn contrast . Dodge and burn contrasts remain constant with changes to base exposure o Ease of operation - Automatically advances through steps when executing a memorized exposure, loops back to the beginning - No doubled up keys, consistent operation, clear display o Extremely powerful and flexible dodging and burning; dodges and burns in stops +/- the base exposure - Only timer with a dedicated dodging mode . Any number of dodges; timer splits and combines dodges so they fit into the exposure time, i.e. combines a 1 stop dodge and a 2 stop dodge . Changes to a dodge exposures do not change the base exposure, burn exposures or other dodge exposures; no ripple-through effects - Burning and progressive burning . Any number of base burns . Any number of burns within a base burn . Any number of burns within burns within burns within... . Store and return to way-points in burning sequences o Automatic test strips and test prints - Progressive test strips at any starting exposure and any exposure stop interval - Sequences of individual test prints at increasing exposures o More - Programmable cold-light start-up delay - Compensate for changes in paper speed - enter one value when using a new box of paper and all exposures are compensated - Percentage compensation for dry-down - Can be set to work as an ordinary 'seconds' timer Owners of the original f-Stop Timer can have their units upgraded to the latest model.
