2017 Photochallenge, week 20: Stack'Em Up - Traffic Pile-up - The 2022 Trevor Carpenter Photo Challenge

We’ve all seen startrails, they’re basically a series of semi-long exposures of the stars assembled into one image. The technique used is stacking. By stacking multiple images together, the differences in each image appear as one. For a long time stacking was the work of expensive editing software. I personally call that a composite image although some purists will argue. It’s quite obvious that we aren’t going to be making star trails with a title like “Traffic Pile-up”. However the technique is very similar to our week 52 challenge from December 2016. We’re just going to be presenting it in an incremental video instead of a single image.

The little video above is what I’m talking about, we’re going to be stacking traffic, although I used cars, the stereotypical definition of traffic pile-ups, you have creative freedom over the definition, allowing you to add your own personal touch to this process.

What I did is fairly simple :

I setup my camera (RICOH THETA S) to do interval shooting of one picture every 10 seconds for 10 minutes.
I stacked the first six images representing the first minute.
I then added 6 more images that represent one additional minute of stacking.
I continued adding increments of 6 images until I reached the total shooting time of ten minutes, producing ten images where traffic incrementally piled-up.
I put together my ten images in a short video in the style of a time lapse.

I did this quickly in photoshop, but I wanted to bring this to the 2017 PhotChallenge in a way that everyone can participate on a budget whether you’re using state of the art camera gear or your smartphone camera.

I found a little piece of freeware designed for startrails that works on MAC, PC and Linux. It’s called StarStax and it does a wonderful job of stacking JPEG images into a single composite image. Here’s the link : https://www.markus-enzweiler.de/StarStaX/StarStaX.html#download

There’s even a Flickr group to inspire you : https://www.flickr.com/photos/stephaniesaccoccio/31637339573/in/pool-starstax/

To complete your challenge:

Remember it has to be a TRAFFIC PILE-UP or a reasonable interpretation of…
You final submission will be in the form of a time-lapse illustrating the gradual pile-up through composite images.
You do not have to follow my timing, however it is an easy formula to follow.

The rules are pretty simple:

Post one original photograph (Your Image) shot each week per theme posted on this blog to Google+, Facebook, or Flickr (or all three). Tag the photo #photochallenge and #photochallenge2017
The shot should be a new shot you took for the current weekly theme, not something from your back catalog or someone else’s image.
Don’t leave home without your camera. Participating in the 2017 PhotoChallenge is fun and easy.
