As an artist you need to keep yourself aflame and inspired in order to run long marathons in industry. One of the best ways to do so, is bringing something to life. This playaround is an example of a quick way to bring a feeling of space and atmosphere to still moments on photos.
You simply take a photo you like, paint depth map in photoshop (in a preliminary step I used a Topaz Lens Fx plugin https://www.youtube.com/watch?v=vGigAEFKPz4), then make a parallax GIF in any soft using depthmap (I used Depthy.me site to get quick result, but site don't work anymore).
I think nowadays the quickest way to achieve that is AfterEffects, a whole youtube is at your service with loads of tutors.
