Lava Cave Pool Lanzarote
This image was taken at the Green Caves part of a system of Lava tunnels in northern Lanzarote which is enhanced by carefully designed lighting. I have taken images from this viewpoint before. 2 years ago when I first started in HDR I took an image with my Sigma wide angle at 10mm, see below.
A year ago I took 3 shots again with the Sigma and blended them into a 3 shot HDR Vertorama. See below.
My latest shot was taken with a Tripod with a Sony A700 with a Samyang Fisheye lens at 8 mm. This produced surprisingly little distortion although of course gave a wider angle of view. For the HDR I took 3 raw images 2EV spacing. Opened in Photoshop first and each image noise reduced with Noiseware Pro and saved as tiffs. Photomatix The 3 images at 2EV separation were outputted in Photomatix detail enhancer. Photoshop I used Topaz Vibrant preset group and clarity preset with the adjustment sliders used for the right look and extra detail. Topaz was applied on a duplicate layer with a layer mask used to remove the effect from highlight areas, A slight S Bend adjustment was made in curves for a little extra contrast. Brightness/contrast the contrast slider was increased 14 points. Vibrance layer increased a little by 17 points. Hue saturation reds channel used to tone down reds in the bottom right of the pool caused by low light noise. The saturation adjustment was restricted to that area with a layer mask. The minus 2EV image was brought in as a new layer, excluded with a black layer mask. Then a low opacity white brush was used to build up more detail in the highlights at the far end of the cave. Layers flattened before going on to sharpening. Duplicate layer Noiseware Pro and a little sharpening. More contrast and clarity added using unsharp mask amount 34 and Radius 34. Note that the point of these setting which are very different from those used for sharpening is that they add extra contrast and clarity rather than sharpening so no artefacts are added. BEFORE AND AFTER Below are the Before and After images. First the original. Then the tonemapped image and then the final result. Original at 0EV
