I will post a making of later, but the images should speak for themselves first. Yeah, you could try to bribe me. ;)
The making of:
What you need:
- 1 sleepy person main_p105061287744.jpg
- 1 camera with timer main_p105060887743.jpg
- imagemagick

How to:
Attach the camera with a tripod or, like me, a clamp. Point towards sleeper. Take a picture every five seconds... or more, if you want to cover a whole night. I ended up with about 500 to 2000 pictures per image.

Now, from every two source images, take the difference. Apply a threshold for the black parts, and despeckle with a median filter to sort out any noisy dust (this is what I missed in experiment #1).

main_threspict008587748.jpgmain_lightpict008587749.jpg

Overlay all resulting pictures with the 'screen' operation.

main_lightpict014087750.jpgmain_lightpict193187725.jpg

The resulting effect is that unmoving parts of the image will stay black. Any movement will take the colour of the difference between the moving object and the background. With a black cat moving, it will pretty much adopt the colour of the background.

These are really beautiful. How were these made?

Thank you. They are motion studies of a certain person who lives with us, sleeping. They are made by time lapse photography and a few digital image operations to detect the motion and blend it all together. I will post pictures of the setup soon.

Even with the full explanation of how it was done, I still don't know how it was done.

Great work.

Appreciation and chagrin

I love the process, I will be following your work. I would normally vote more than I have just done for tasking of this quality (likely a 4), but there is a cat-fancier penalty in my scoring system. I don't mind that other people love cats, but the internet is replete with them already, and so I put my øconomy where my mouth is when it comes time to vote.

Thanks Waldo. I appreciate that.

The final choice fell on her mainly for practical reasons: She is the only one who is actually able to sleep with regularity in the necessary daylight and the presence of blinking (and sometimes beeping) tech.

Oh, and thanks Ben Yamiin and all for the unexpected... attention.
