Wanted to do a product like shot of my bike that sometimes can be seen in magazines with multiple strobes highlighting the bike.
Instead of charging up all the batteries for 3 flashes and lugging them and lightstands downstairs, I opted to do light painting with the bike's front light instead.
Mounted the camera on a tripod and shot 3 exposures each with the light shining where I would have placed a strobe (ie. front 45deg; left rear; right rear)
Merged them in PS using the "lighten" overlay option.
The lens is nothing special for Rollei, but holds special value to me as its a made in Singapore version of the lens where I am from/in.
I had it converted to M42 mount, so it also works on a Pentax camera
