tide pools

Tide Pools at Tanjung Simpang Mengayau (Tip of Borneo).­ This is the Northernmost point of Borneo Island.­

For more information about this place, read en.­wikipedia.­org/­wiki/­Tanjung_­Simpang_­Mengayau

Those rocks are very slippery and this place can be dangerous (I slipped, fell in sea water in a deep hole and bumped my knee pretty good.­ Camera survived the fall, thanks goodness).­ Go at your own risks!

Photos processed in True Tone HDR.­

Those are High Dynamic Range (HDR) photos processed to represent the scene as observed by the human eye, i.­e.­ without some of the surreal effects that can be obtained with "heavy" tone mapping of HDR images.­

I sometimes do HDR processing from a single RAW exposure, since my camera has about 6-stop dynamic range in RAW mode.­ This is the only possible way to do HDR when shooting a moving subject.­

For those wondering about the technical part, here is some information about my workflow for producing tone-mapped HDR images from a single RAW exposure:

- The RAW image is used to generate 3 images using exposure compensation with Photoshop using Adobe Camera Raw: -2EV, 0EV and +2EV.­ This allows to capture about the entire dynamic range stored in the RAW file.­ You could also use Lightroom to do that too, or any software than can process those RAW files.­ In my case, I need to first convert the RAW files into DNG format (using the standalone Adobe CameraRaw Converter) because the version of Camera Raw that I can use with my Photoshop is not compatible with the RAW format of my (recent) camera.­ But you don't need to go through the DNG step if you have the latest Adobe software.­

- The 3 images (-2EV, 0EV and +2EV) are then merged into one HDR image using Photomatix (you could also use Photoshop to do that).­ This is basically an automatic process with no parameters to adjust.­

- The HDR image is then processed with Tone Mapping to obtain a displayable image.­ I use Photomatix for the tone mapping.­ There are many knobs that can be adjusted, but in general, to get a True Tone realistic image, I use 25% to 50% intensity in the Tone Mapping dialog.­ I then save the resulting tone-mapped image in TIFF format.­

- If needed, I then correct Chromatic Aberrations using the free and automatic Photoshop plugin from Photoacute, which works very well most of the times.­

- I then use standard Photoshop layers to do the usual final adjustments (Level, Curve, Saturation, Color Balance).­
