Many guides out there are going into how to do double exposures with analog cameras. Just type the question in google and get a lot of answers. I like to do it with the Hasselblad Xpan as it always brings the whole film in. After taking my images, I put the same roll in again, and it starts at the same frame. Either you are going wild or remember (smartphone images help your memory) and take the second images afterward. I like this form of doing double exposure as they look different and have some surprises. Furthermore, using film and seeing the picture later makes me feel the sense of presence again. It makes the process more challenging, but if you nail it, the satisfaction is immeasurable!

So go out and embrace and anticipate the surprises.
