tree logs loaded on a logging barge

Tree logs are being loaded on a logging barge. Old growth rain forest is cut and logged to make room for oil-palm plantations (Borneo)

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 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 I use the default setting and I increase the color saturation value in the Tone Mapping dialog.­ I then save the resulting tone-mapped image in TIFF format.­

- 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).­
