I’ve continued to explore HDR (High Dynamic Range) imaging, trying out different tone mapping algorithms. The following image was processed with the Mantiuk algorithm, and gives a nice, illustrated look:

In imaging, dynamic range refers to the difference between the brightest and darkest values in a scene. Cameras are not able to capture as much dynamic range as our eyes, and most display technologies are not capable of representing them. I’ve been doing some experiments with HDR imaging and processing, because I think the process […] Just returned from Brazil, here are a couple of nice panoramic shots from Rio. The first is the famous Rocinha favela, the second is an overview of the Rio beaches taken from the Corcovado mountain. Click on the images to see the (huge) full resolution versions. More photos from my trip here.

Unfortunately, there were only a few moments of totality visible before sunrise, and there were a lot of clouds. I did get a reasonable picture of a partial phase. Just got back from Sipadan in Malaysia. Amazing dive site – loads of sharks, sea turtles, barracudas and every variety of colorful reef fish. Sipadan Water Village is a very well-organized scuba resort. As soon as they get their quota allocation from the government (only 120 divers at any time on Sipadan), they plan […] Well, actually, it isn’t. Found it in Sim Lim Tower (Singapore), marketed as Nano Gen II. It has a bigger screen, built-in speaker, FM radio… and a diabolically useless user interface, all for S$55. (The real iPod is on the left…) Interesting van, often parked a couple of blocks down from where I live:
I wonder about the reference to the bees – perhaps something to do with this? I’ll be going scuba diving in Sipadan (Malaysia) later this summer, so I figured it might be a good idea to polish up my (extremely rusty, +20 year old) diving skills.
The picture shows me in the pool at the 14th St. YMCA, doing my confined water dives for PADI certification. A […] |
