Here's my catshot from about a few weeks ago, in comparison to yours it was taken at ISO 51200 "only"
Hi Pedro, no coincidence at all... I was actually inspired by your original cat pic and wanted to test with more stringent (loony? lol) conditions... given the detail we see in the comfortor I thought you had "low" but some morning light to provide the DR apparent. I also wanted to push the ISO to the max. I really didn't expect to see much at all in the pitch black room with a point light source, but was pleseantly surprised, so I wanted to share.
For the record, I will never take shots like this in in the dark at 1/1000sec in real life. but I am learning a lot in the process of this experiment
@Ray: Wow. Thanks for this one. You did great! Dare to go the limits, it is less harmful than bungee jumping
