I'm in the midst of reading the David Lean biography which has been fascinating, particularly learning how he started as an Editor (and quickly became regarded as Britain's best by many). I'd strongly recommend it to anyone interested in the man.
In conjunction with reading the book I'm taking the time to watch his filmography too, starting with 'In Which We Serve'. I've just finished and one of the things that caught my eye was rippling dissolve effect they use when transitioning from the scenes of the men in the water to the flashbacks. I've tried finding it on YouTube but although the full film is there the quality is not very good.
If anyone remembers the effect I'm referring to, do you also know how it was done? I've done some research and there seems to be multiple possibilities but I couldn't find anything concrete.
Thanks in advance.
