VA3AWP’s HAM Shack In HD – Nikon P510 720p Test

*****EDIT***** It looks like YouTube likes to darken video’s for some strange reason when you upload them in Apple .MOV format. The video is much brighter when viewed in any media player like Windows Media Player, VLC, and QuickTime. I’ll see if I can fix it using YouTubes editing filters.

Just testing out my new Nikon Coolpix P510 that I picked up a couple days ago. The video being shot is in 720p in low light conditions in my amateur radio shack. The video was directly uploaded to YouTube in Apple .MOV format, there has been no editing or processing of the video.
