Only intended as a constructive comment, but the motion is just not smooth enough, has a handheld with IS lens look.
There is a reason that for very smooth and clean motion control a lot of motored jib/cranes are used which also help in reproducing/tracking the same movement if needed.
Indeed - this was MK1 of home made jib, there was flex (bounce) in the 1960s gitzo head that I was using, Ive found a frotto head that is giving better results - my main video head a miller is used on the front of the jib and I cant affrd a second fluid head right now at $1500
shooting with a 50mm macro is a big test of a jib and focus pulling
I still think manual operation can be more organic than a machine, especially if you are following a moving human (which I was not in this case)
Forgetting the technicalities my main point is that my client.. Candle Company
(no i didnt shoot the indivudual product images) has a rolling slideshow on their homepage
I see it being swapped for a looping flash video of this nature - i am trying to gain the skills so that I can offer them this service - and others
