I'll see you in London at the end of March?
Yes, looking forward to it.
Actually this was actually pretty fast to process - now I've learned how. The batching just took a couple of minutes to set up (a bit longer to run) and then assembling the sequence once I was working with low res (1920 pixel) jogs only took a minute or so (on my main computer).
On the newer cameras I will do topside time-lapse in camera - but I think I will do UW ones as JPGs - so I can adjust colours in post using software I know, rather than software I don't. Although with increasing video capabilities in Lightroom and PS - I may not.
All that said - I feel the opportunities for time-lapse are fairly sparse (unless it is your total focus). And I wouldn't waste my precious dive time on it unless I had a second camera. (I don't know how much you have to dive until dive time doesn't feel precious).
