Magic Lantern HDR video to tonemapped video with MATLAB scripts

I have a Canon T3i with a Canon EF 50mm f1.4 lens that I use for the gross majority of my day-to-day photography these days. I’ve been using a custom firmware for the Canon called Magic Lantern that provides a some interesting (and useful!) functions. One of them is HDR video. Here’s a beautiful example of what can be done:

I tried my hand at processing the HDR video output and was able to get a reasonably nice tone-mapped video:

After the break, you’ll find how I processed the initial Magic Lantern video using MATLAB and exiftool and tone-mapped the output using Luminance HDR.

Johannisbeeren (red currant) Pastries

Another baking-related post, because I had the time on the weekend to do some more cooking while my wife was out of town.

In my last post, blueberries were on sale. This time, Johannisbeeren were on sale, so I wanted to take advantage of the fresh fruit. Johannisbeeren are unfamiliar to me, being an Eastern US native, but I find them incredibly delicious. They are tart like a cranberry, but have a great “berry flavor” when sweetened that I find hard to resist. There are lots of Johannisbeeren pastries and tarts available here in Hesse, Germany, but this was my first opportunity to work with the fresh fruit. And without further ado, here’s a video demonstrating how I made puff pastries with fresh Johannisbeeren, with CC-licensed music by Jill Zimmerman.

Puff Pastries with Blueberry Compote

Ok, so this post is not shape or electronics related, but still a fun little side project. Since I started working at Justus-Liebig-Universität in Gießen, Germany as a postdoc, my wife and I have cooked as much homemade food as possible. Germany is full of fantastic, inexpensive, and fresh ingredients, so we want to take advantage of whatever is available seasonally.

This week, blueberries were on sale, 0,49€ for 200g, and puff pastry dough is really inexpensive as well, 0,69€ for a sheet. So, here’s my first attempt at a “foodie” video demonstrating how I made puff pastries with fresh blueberry compote, with CC-licensed music by Jill Zimmerman.
