#time slice

According to Bryn Athyn photographer Steve Conroy, this is called a “time slice” which is essentially a collage of photos taken in a time-lapse sequence, all put together into a single image. The photos were taken on January 14th. You can follow Steve on Instagram (@steveconroy).

Mesmerizing “Time Slice” Photos Show Single Locations at Different Times of Day

Here's a few different ways to process timelapse footage. In order of appearance (each segment is 8 seconds long) Timelapse (multiple photos used to make a video) Time stack lapse (every frame is a time stack made from multiple photos, this one uses the lighten layer blending mode) Time stack lapse (same as the previous clip, only this one uses the mean layer blending mode) Time Slice Lapse (each frame is made from slices taken from 342 photos) There's 4 clips each sliced with a different direction. The first one is north, then south, east, and west. The last clip is a time-slice-stack-lapse which is a combination of all the time slice lapses, "stacked" using the lighten layer blending mode. As usual, I made the music, but instead of making something new, I just reused an old one.

Tick ~ Second.   Dobash ~ Minute Tock ~ Moment ~ 90 Ticks Varga ~ Hour Quintant ~ Day = 20 Vargas Movement ~ Week = 5 Quintants Cycle ~ Month = 4 Movements. Feeb ~ Year = 13 Cycles Decafeeb ~ Decade = 10 Feebs

I took a short video of myself drumming to see what it would look like time sliced, and also to get a feel for what works best when creating source material to be time sliced. This was 1280 x 720 at 60 fps. Which I sliced vertically (with east as the direction - so time reads left to right) Each frame of the video is made with 320 photos. A 4 pixel wide vertical slice is taken from a different part of each photo, so the final image shows a progression of time moving across the frame. I couldn't get the video to line up with the sound, and I don't think that would be possible with this technique, but I kept it in to give you an idea of what I was playing, and possibly how my arms were moving. I should have took a clip after warming up, where we did something cool, but... this is just a test, so there you have it!

I've been experimenting with time slice photography for a few years now, and more recently with time slice lapses. The source material I've used (to create the time slice images) has always been from my timelapses, and I wondered what this technique would produce if I used video frames for the source material. The main difference is the time between each frame (known as the interval) When shooting timelapses, the interval time can range from 1 second to minutes, or even days if you like. Using video footage the interval is much faster, just fractions of a second between frames. For this test, I used video of a fire shot at 60 frames per second. The top image is a single frame from the video I used for the source material, and the bottom image is a single frame made with vertical slices, using the time slice process. Here's the time slice video I made, so you can see what the bottom image looks like in motion. https://www.youtube.com/watch?v=Cdq8xz5506Y&feature=youtu.be I'll have to try this with another subject, because fire changes so quickly, that the results appear similar to what you get using timelapse footage, with a much longer interval. So the next test I'll be looking for something that changes slower. You can put suggestions in the comments if you like.
