Time Lapse Photos Outside RC's Woolloomooloo Office (THESE ARE REAL!)"A friend and i set camera to capture fruit bats rising from Botanic Gardens, this was a big surprise."The 'Gladiator' star linked to a YouTube video showing three time-lapsed snaps featuring a cigar-shaped red flare in the sky, seemingly firing a beam onto the ground.Â Russell, 48, dismissed responses from fans that the strange sighting was the result of a camera flash, tweeting: "Canon 5D, No Flash, can't be a lense flare because it moves , camera is fixed (sic)"He continued to deny there was any trickery involved aside from some music being added to the YouTube clip and the images being zoomed in on.He wrote: " It's not a video it is 3 time lapse photo's taken in 4.5 seconds. I will grant you at the time the music wasn't playing, also, yes, we have pushed in on the frame ... this is 3 photo's in order, nothing added.
