As a precursor, let me reiterate, these blogs are for intelligent people with a university background and courses in mathematics, engineering, physics and other of the hard sciences. The first HDR image was the result of the independent work of Prof. Paul Debevec, U.C., and Gregory Ward Larson, JPL. Prof. Debevec developed an algorithm to composite several images into one. His work was published in a research paper still available online. In the back of the paper is a Matlab script of the algorithm. Matlab is published by Mathworks, Inc, and is the foremost mathematics laboratory, Matlab is widely used by scientists and professionals in a science related field. One of the unknown benefits in HDR is the ability two construct an HDR image with only two exposures (images) if the same film is used for several images. Prof. Debevec derived an additional algorithm for determining the film character and using that data to reduce the...
Since the last major post, I have acquired 3 USB microscopes. These are not full-fledged microscopes, but devices that have zoom factors and light sources. One comes with screenshot/video recording software. I used this to examine a phonograph needle on my turntable. I had enough detail to determine the source of a playback problem. As a result, I purchased a new stylus and now enjoy my LP collection.
I've been spending a lot of time and energy on digital movies lately. I've acquired a collection and installed database software specialized for movies and or media in general. There are many such programs available and I decided to find the better ones and put them to the test. You would be surprised at the problems that can arise when the user context does not overlap the software use plan exactly. Anbother way of saying personal habits can result in problems if the program designer thinks differently than you, and narrowly. Human factors engineering is important in software. Easy to learn and use software becomes popular if the program does what's expected well. People will pick an easy to use software over a difficult, obtuse, piece of software given all other thing are equal. I used a DBM (Database Manager) that is popular and free. My problem was, the programmer wrote the program from the botom up, and not top down. T...
