What do any of the things in the post title have to do with each other? Nothing, except that they happened last week.
Zombies walked the streets of San Jose last Wed. for the Zombie-O-Rama. I went with a couple friends to watch and take pictures. Grrraaaahhh, braaaaiiins.
At work, I've been doing something that I am pretty proud of. I've been doing research into getting high-resolution normal maps from 2D pictures. For those of you who don't know what a normal map is, it's like a bump map: a picture which describes height instead of color on a 3D model. Very useful for 3D models with simple geometry. Example, a wall with bricks. You can have one big polygon with a normal map, and it looks like the grout is indented.
I've been experimenting with taking a photo of, say, my face with a big soft-box for light to get a diffuse picture (no shiny specular highlights), then pictures in the exact same position with a flash on the right, left, top, and bottom. Then I can get the difference between the diffuse and the diffuse+specular photo to find
just the specular reflections. What this does is give me an image that looks kind of like a bump map of all the little pores and wrinkles in my skin ( with dark being indented, and white being raised).
It works remarkably well, considering the do-it-yourself nature of the setup. I was able to get something that looked comparable to a head scanned by a multi-thousand dollar 3D scanner. Yes, it did take some extra work, but if I had everything already set up, I think I could do a head in half a day or less. If I had a little extra money to get a more ideal setup, it would be even better!
This weekend was spent up in Lake Wildwood with Susie and Ray at their lake house. They had an inflatable kayak that Kristin and I paddled around the lake on, and Saturday night we went to a dinner/dance in the park that was a lot of fun.
Sunday, I had my third wedding photo gig, and the first one with 100+ people. It was mostly a favor for a friend of mine was the maid of honor, but I was paid a little. It was a good learning experience, but makes me glad I don't do this professionally. I think I did right by them, but there were some equipment malfunctions that ruined a few non-critical shots. Very stressful.
