This is actually a triple exoosure. I used the following three images and created the effect in PS.

This is the original image with no editing. The mannequins were situated on a table in front of evening light. A sheer curtain is separating them from the background. Below the mannequins, I have my prism.

Nothing too interesting here. Bluebonnets and roses from my garden.

I saw these clovers and didn’t feel like I was getting good results focusing on the clovers. So, instead, I did not focus, causing the bokeh blur.

Notice JV in the background :)

I wanted to practice silhouetting my subjects, as well as posing.

The wavy rainbow is caused by putting a prism between the camera and the subject. I suspect the curtains caused the wave in the light.
