The attempt at a long term time lapse with the rotting tomato worked better though there is still some flicker. It is probably better to use a dark background where it would be less noticeable if there is slight variation in lighting.
This is 270 photos taken at one hour intervals over eleven days.
The photos were made in to a video using Zeitraffer on a Mac.
Following a hint from Adrian I replaced the green background using iMovie's green screen masking effect:
Trial number three is under way using a different background.
