Drain in White II
This is the last of my HDR experiments at the Ross Bay storm drain that were taken last weekend. The main point of these experiments was my curiosity as to whether one could simulate the very long exposure effect with many shorter exposures blended together in HDR. The longest exposure that my camera will take with its own timer is 30 seconds and I have been thinking the creamy soft water that I would like to get in my photos requires even longer exposures, or maybe a HDR work-around.
These are the best of the work-around tests and I think that mostly I have the look I was after. However, it is a lot of work to get here, and I expect that were I to take single exposures in the 2 minute range I would be getting a similar look, with a lot less post processing. To that end I have bought a remote timer and plan on giving it a try, when conditions are suitable. Another advantage of the very long single exposure if that moving objects, (such as the ship on the horizon below the dark rectangle of mountains in these shots), will be a single blur and either disappear, or be a smudge. In this composite image the ship is fairly clear in the two slowest brackets, but has moved between when they were taken and thus shows as two vessels on the horizon, indistinct and a bit odd.
Of these two versions, I think once again I prefer the colour – I think the colour of the kelp in the foreground helps set the path for the eye through the photo much more effectively than in black and white. But, if I only had the black and white I would be pretty happy with it.
These photographs are merged from 5 brackets using the Photomatix plug-in for Lightroom 4. This plug-in generates quite natural looking 32bit files which it places directly in Lightroom without any real control over what Photomatix is doing. All the editing happens in Lightroom instead, which is what I have done here. Today’s pictures are both made from the same set of brackets.
I actually seem to have loaded a number of images with the same exposure value (8 seconds) and I don’t know how these were handled. The file name suggests I used 9 brackets, but when using Photomatix directly (rather than via the plug-in) it asks if it should discard the ones with the same exposure value, or change their value. So, maybe they are all in there, influencing the mix, or they have been ignored if the same. I probably will never know, unless I try redoing it without the duplicates, which I probably won’t.
