My final project for the Computational Photography class at GaTech. Multi-scale image contrast/detail manipulation Operating on images at multiple scales is conventionally done using multi-scale decompositions, such as the Laplacian pyramid [Burt and Adelson 1983]. Such techniques decompose an image to multiple detail layers at different scales in a pyramid like fashion. This project demonstrates how … Read more
I recently picked up a copy of Topaz Adjust 5 (released November 15th 2011), and fell in love with it! Here is a simple mini-review and some first impressions of Adjust 5. Topaz Adjust is a photo-editing plug-in developed by Topaz Labs that integrates into editors (such as Photoshop) by adding auto exposure, contrast, and … Read more
Usually, when I’m using GIMP to edit pictures, there are a couple of simple enahcnements I routinely apply to each image. So, I’m slowly learning GIMP scripting and creating some simple GIMP scripts to help automate some steps in my digital darkroom workflow. Here are two scripts that I’ve come up with so far, that … Read more
April 2011 Abstract As a final project for my Computational Photography class at Georgia Tech, I created an application that uses a single video camera to create tonemapped HDR images in real time. This project’s inspiration comes from Soviet Montage Production’s DSLR HDR video. The app runs on Linux PCs (using USB or Firewire … Read more
After installing the new plug-in registry for GIMP, I stumbled upon the amazing National Geographic Script. It is incredible! This script simulates high quality, vivid photos – like the ones from the National Geographic magazine. It uses a configurable mixture of shadow recovery, sharpening, local contrast, and various color overlay layers. The script is buried … Read more
