This technique has been around since the film days and is often used by photographers back then to add more drama to their shots. Most modern DSLRs (especially nikons) have this feature built-in. For more info on how to do it, do a google search for "multiple exposure" or "double exposure".
I have tried this before in college using film but wasn't too happy with my results, which is why when i shifted to digital i did not bother to find out if this technique can still be done. But recently i came across some excellent examples of multiple exposure using DSLRs so i tried it out. Below are some of my initial output.
Thread RULES:
1. Photos posted must be yours.
2. Multiple exposure should have been done in-camera, either through the Multiple Exposure option or Image Overlay tool. NO layering via Photoshop or other external editors.
3. Global post-processing in Lightroom or same software is OK.
3. Keep photo dimensions at 5oopx long edge to make loading faster for those with slower connections or on mobile.
