HDR Chrome Effect in LightZone

An popular effect is the HDR, gritty, "chrome" look. After watching a video on the technique, I thought I'd give it a try in LightZone.

This look is achieved without actual HDR, but by contrast, local contrast and saturation adjustments.

The steps in LightZone involve dropping a number of tools on the stack and adjusting them, which is a different approach than Photoshop or Lightroom.

  1. Drop a Hue/Saturation tool. Set Vibrance to 100.
  2. Drop a Sharpen tool. Set Amount to 500 and Radius to 50, adjust until you get a "comic book" or "chrome" look (strong blacks, faded, three-dimensional pastel colors).
  3. Drop a Zone Mapper tool. Define points at 2 steps down from white, 5 steps down from white and 4 or 5 steps up from black. Push the white point up to where it divides the top step in two, leave the middle point alone, pull the black point all the way done to keep contrast. Later, you can adjust the middle tone contrast by adjusting the middle point.
  4. Drop another Hue/Saturation tool. Pull the Saturation slider back, reducing saturation until you like the effect.
  5. You may choose to drop a Relight tool to adjust overall brightness and graininess, but you may want to zero the Detail slider or turn off the Sharpen tool and use the Detail adjustment instead.
So you do not have to go through all of these steps, I created the HDChrome style you can download for LightZone here to use as a starting point. Download the archive file, extract the .lzt file and save it to your LightZone templates folder and it will appear under Custom styles.

Reducing saturation gives an image the feeling of a drawing, as if an ink drawing has (or photograph) has been tinted. Starting with a pastel image, mostly gray with touches of color gives this result, if there is texture, this will become the "ink" part. If you start with a metal object, like a car or motorcycle, it can enhance the curves and create the appearance the metal has been chromed, and enhance already chromed parts.

Minolta Lenses on a Four Thirds Camera

During the summer, I bought an Olympus E-510 digital single lens reflex camera. The 510 is a FourThirds camera and because of the of shallow flange of the 4/3 lens mount it is one of the most flexible cameras on the market when it comes to mounting legacy optics (lenses from traditional film SLRs). A 4/3 camera can mount "legacy optics" or lenses from several other manufacturers made before the DSLR era. Although unintended, this makes FourThirds a revolutionary mount. For the first time not only can a photographer mount lenses from different manufacturers who produce lenses to the "open" FourThirds standard, with inexpensive Chinese-made adapters lenses from nearly any manufacturer from the golden age of SLRs can be mounted as well. Third party adapters can be found for Olympus OM, Nikon, Pentax, Zeiss and Contax. The only one missing from the party was Minolta. I purchased an inexpensive OM to 4/3 adapter from ebay and mounted several OM lenses, a 50mm f/1.8, 50m...

Snowball, the Dancing Bird

A video of a dancing bird has become the latest YouTube sensation. Some people thought the bird's performance was faked, but for me, it is not surprising, given the sophisticated ability birds demonstrate for manipulating pitch and rhythm in their songs, that a bird shows the ability to keep time with music. Neuroscientists, including John Iversen of the Neurosciences Institute, have studied the dancing bird and confirm it is capable of extracting a beat from sound. What impressed me most about Snowball's performance is when he lifts his leg and gives it a little shake before bringing it down. As the investigators mention, it may be prompted by the pace being too fast to put his foot all the way down in time with the faster beat, but it piques my curiosity further. It appears Snowball is dividing the beat when he waves his foot, into two or three little waves, which if I am seeing it correctly, suggests birds are capable of division of the beat and perceiving and manipulating ...

Facilitating the Conversation

I was prompted by something Andrew Shafer of Reductive Labs said (on the FooCampers list, so I won't reproduce it here, since it was forwarded to me) about the quality of communication among software developers. He was talking about how communicating the overall design and intentions of the project is vital, so the developers are not left guessing about how the application will be used and what its architects think it should do. What is important is the existence of a conversation between the leaders of a project and the developers writing the code. This hits very close to home, because our farmfoody.or g project is essentially there to improve the flow of information between producers and consumers of food, to enable a conversation . It occurred to me the solution is to throw away the flash cards and bulleted design specifications and just facilitate the conversation. Why not use social networking tools for developers to communicate? (You can get a sense of another approach from ...
