Getting Around in GIMP - Polaroid 600 Film Border Script
A while back I had written up a post and some Script-Fu for GIMP to emulate the colors I was seeing from very expired Polaroid 600 Instant film. That older post is here:
Getting Around in GIMP - Expired Polaroid 600 Film Effect
I basically loved the nasty color cast and funky things that part of the image did where the developer had dried up in the packets, and there wasn't enough left to fully cover and develop the entire image area. If you head on over to that post, you'll find what I did as well as color curves and some other Script-Fu to automatically apply those colors and degradations to your images. It's also located at the GIMP Plugin Registry right here.
As part of creating that script, I also wanted to create a more realistic looking border script that would emulate the embossed patterns found on the original 600 Polaroid film.
Visualize Photography Lighting Setups in Blender
The most patient portrait model in the world...
Not too long ago I finally got around to picking up a decent manual flash for exploring lighting and speedlight techniques. I picked up a Yongnuo YN-560 Speedlight Flash for Canon and Nikon
, and my friend Sean was kind enough to send me his old radio triggers to play with. I was mostly all set to start exploring the world of off-camera lighting...I say mostly because though I had a rough understanding of how I wanted to use the light, I was not well versed on what could be done with it. So I spent a bit of time on the Flickr Strobist Group, and read through all of the Lighting courses on the Strobist site. There is an absolute wealth of information on the site, and I cannot recommend it enough.
Having a reference for how the contribution of different types of light will affect the final outcome is very handy for me. I've seen people who have taken the time to setup lighting diagrams where they will modify a given light for direction/angle, and cycle through many possibilities to help as a reference (Here is one cheat-sheet from DIY Photography).
This is nice, but what if I wanted to visualize the effect multiple lights will have all simultaneously? I guess I could go and shoot every, possible, variation, but I am really lazy. Plus, I don't have access to a model with the patience to sit there while I fiddle with multiple lights, multiple times.
It occurred to me that I already had a great tool for doing this visualization already installed on my computer. That tool is Blender 3D. I already had been using this open source 3D modelling tool for some time, and was familiar enough with it to be comfortable emulating my lighting setups. All I needed was a good model.
