Vertical concentrated time-lapse (day 44)

Posted in 100 day challenge with tags , , on January 27, 2011 by dingobat

Todays post is a little technical but the process described yields an interesting result. I liked the idea from yesterday of a concentrating a time-lapse into one picture. The problem is that the number of photos that can be included in the picture is limited by the time it takes to manually cut out the individual parts and put them back together again. I researched on how to automate the process and found the open source software ImageMagick. This image editor has a very cool feature, it can be used from the command line and can process a batch of photos based on a script. To get the script part working in Windows I had to install Cygwin and run script through that (“Linux-like environment for Windows making it possible to port software running on POSIX systems” according to the website).

Luckily I found an already made script that did what I wanted it to do. What the script does is to cut out a vertical slice (a few pixels wide) of each picture in a folder and then “glue” them together into one picture in chronological order. The process is described in detail on this page.

These are my results applying the scrip on my kaleidoscope and ice melt time-lapses.

Concentrated time-lapse (day 43)

Posted in 100 day challenge with tags , on January 25, 2011 by dingobat

These pictures consist of squares cut out from time-lapse photos I have taken from the kaleidoscope time-lapse and the ice melt time-lapse. The idea is that by building a mosaic of part of these picture, a slice of time is portrayed in one frame. It would be really nice to try this out on a time-lapse with more activity e.g. a busy metro station or a “from dusk till down” time-lapse.

The first picture has the photos in canonical order starting from the midpoint and moving outward in a spiral, with the other picture this is reversed with the first photo starting in the upper left corner.

Just an add-on on yesterday’s post. This is the time-lapse video made with the kaleidoscope lens.

Time Lapse Photography (day 2)

Posted in 100 day challenge with tags on December 13, 2010 by dingobat

It was quite frustating yesterday because of the problems making the the little planet. I spend a lot of time on something that really did not turn out very good. Today’s technique was luckily more succesfull and a lot less frustating.
Timelapse photography is something that has been on my todo list for a long time but I never got around to actually trying it. To have a reason for trying these different photo techniques is actually the main reason for writing this blog.

Timelapse videos consist of a number of photos taken over a extended period of time with each still photo as a video frame. It is basically a video on super fast forward so you get to see change over time condensed into a short video clip. I choose to make a timelapse video of ice melting because of conviences (there is a lot of ice around this time of year) and because I wanted to something that was easily controlable since it was my first attempt at timelapse photography.

To take the pictures at 10 seconds intervals I used my canon pocketcamera with the CHDK firmware hack so it was able to run a intervalometer script. There is a nice guide to doing this avaliable from the Hack a Day blog. To turn the photos into a avi movie clip I used the super simple MakeAVI (it does excatly what it says it does).

This is a picture of my setup

And this is the resulting video
