99.9% of the time, you will want your lens attached to your camera body. That 0.1% of the time is if you’re freelensing.
WARNING: Obviously, since your lens is not attached to your camera, there is a possibility that dirt and water may get into the body. Be careful!
Now, onto the fun stuff! Freelensing is exactly as it sounds: the lens is free from the body, allowing for you to shift the focus plane and add light leaks to your photo (those bright color spots you see in girls’ Instagram pictures).
Here are some examples:
It’s done in a few easy steps:
- Set the aperture to the lowest number (or one step up)
- Focus the lens to infinity (farthest away from camera)
- Remove the lens from the body
- Hold the lens close to the body
- To focus close, move the lens away from the body
- To focus away, move the lens toward the body
Here’s a video to show how it’s done: https://www.youtube.com/watch?v=WerEA1BZRYA
This is what it looks like when you’re doing it:
I like the effect that you can get in camera with this technique. It’s easily accomplished in post production, but this allows for fine tuning and control of your image.
