I guess perception or the event of peeceiving an ongoing event also happens with time passing. I wonder if we can perceive things and freeze time simultaneously. If we can, we are freezing the moment but we are no longer time bound. It quite similar to me appreciating the serene photograph you have shared but i am letting time elapse in that moment, even if other things have stopped for me.
And i guess you are right, if time stops and if our ability to perceive stops with it, then to us, we will experience nothingness. Some say it can also be achieved in a deep meditative state, when time stops and so do our thoughts.
