With the application of multi-exposures with different lens, filter and camera settings you can create some interesting results. For example image 1 (below), with a tripod, 2 frames and different shutter speeds (mixed with an ND filter) and a cable release, I was able to create this double exposure. The first exposure was of the building with some cloud in motion (yellow). ND+9, 30 seconds. The second frame, still cloud and plane, faster shutter speed without ND filter. You can even try changing lenses, if you're after 2 frames with say the building, then try not to move the camera too much when changing lenses. This can get quite a bit to manage, especially remembering your framing / compositing.
Image 2 (below) is simply multiple long exposures shot on a single frame. With the use of different shutter speeds, you get slight movement in the clouds (transition) and wind movement layering from the leaves in the trees. And of course light bands from the cars. Taken late afternoon. A mixture of points of interest creating a unique perspective to street photography. Use of an ND filter to control light and allow the use of long exposures during low light.
There really is not limit to creativity with regards to changing lenses, creating layers, different shutter speeds / use of filters to control exposure.
All settings listed are approximations only. I use an app for my ND shutter speeds. "ND Exposure". It's easy to use and requires a little bit of brain power.
