picked up a set of ND filters from Best Buy, this is a link to the filters at Best Buy, and decided to put the C-GO3 on the steadygrip and put together a quick video of how they "performed". if you have any questions please let me know
heres a pic i took using the "gorgeous" setting, i believe. not sure on any other setting, but Im guessing it was with everything in auto. hope were able to help. looking forward seeing some of your work :)
here is a quick video i did, last Oct, that was able to catch the colors as i saw them. believe i was using the "gorgeous" setting, 30fps and 1080p.
no editing in post, just trimming of footage.
