I am trying to get in to long exposure time lapse photography and I was wondering if there was a way of speeding up or turning off the processing of the image! When doing long exposure time lapse at for eg 15 second exposure, once the image has been taken the camera then processes the image which can take a further 15-20 seconds before it allows another photo to be taken!, can this processing time be sped up or turned off to allow filming to be quicker?
