Coding a Timelapse Plugin for Photoshop | Image Processing Hack

Want create site? Find Free WordPress Themes and plugins.



Two years ago, I wrote this Timelapse plugin “hack” for Adobe Photoshop to automatically detect and fix exposure changes in a Timelapse. This is most useful in difficult lighting conditions such as a sunset or sunrise. In this video I explain the entire process of figuring out how to parse image data, apply image processing and how this translates into the code! Luckily once you understand the how Photoshop interacts with metadata, the code becomes very simple. I remember taking on this problem when I had no idea what I was doing. It really seemed like an “impossible” task since I had no idea how image processing works. Turns out I found a very simple solution using my knowledge of camera settings to compute relative exposures 🙂 Leave comments on any ideas for future development of this software! We can apply any image processing to RAW images through the same methods applied in this video. Read the project page (link below) for more information on how to shoot these timelapses and use my program effectively.
