I remember reading that article a while back .. but what struck me as strange wasn't that you can't get good images in such light. It was more about the fact that none of the images posted were actually captured in bad light!
Same with yours Adam. That light is not actually bad. In fact (as you show) it's actually quite OK. I think a bit heavy handed on the clouds .. but that a personal taste preference.
Bad light (for landscapes) is a totally featureless grey sky. That is, no matter how hard you punish those pixels, it's nothing but a flat featureless grey mass, and therefore no interesting light quality on
terra firma neither.
Of course this doesn't necessarily mean that you can't still capture an interesting image, as long as the subject matter is strong and the elements work well together you can still get an interesting image out of a flat grey scene too. It's just not easy to find such interesting elements all the time.
I wasted a trip to Lake Eyre a few months back arriving in flat grey featureless conditions. They started out OK, watched the weather forecast, and saw that there was more likely to be good skies when I arrived. But it turned grey on me for 99% of the time I was up there.
Had the skies been anything like what you got there, I'd have stayed another day or two.
But, as I also learned the hard way, even with such flat grey conditions, you still need to be prepared.
The 5 hour drive back from the lake, down to Wilpena Pound, was all the same grey flat featureless conditions again. I reckon it's about 300-400 k's or so. I thought if the sunset looked like it may come good, I wanted to be around Wilpena. As I approached Wilpena, the skies were still too dull, so I kept heading(towards home) .. but as always via Kanyaka ruins. Another almost hour drive, and yet still more of the same dull sky. I was still going to get to Kanyaka anyhow .. irrespective of the conditions. Kanyaka is one of those sorts of locations.
But of course, about 30sec before I pulled up at the ruin itself, the sky lit up like a wild fire. it takes about 30 sec to 1 minute to travel the gravel road to the car park and I reckon I did it in 10seconds!
Mad rush to get there, out of the car and setup with one of those awesome sunsets, but as I plonked the camera down, on tripod, with grads setup .. the sky basically died.
As
Max would say ..
"missed it by that much!" .. literally, 10 seconds or so.
I got the very tail end of it, with minimal amount of colour in the sky, but again I wont push my processing so far as to produce something that wasn't actually there. I haven't posted that image up.
20 seconds later when I was actually ready to shoot
.. of course all colour in the sky was gone. I loitered in the area for about half an hour, just in case, took a few snaps of this'n'that, and headed home.
Sometimes you just never know.
But as for your image, I'd have given my Siggy 10-20mm for a sky like that whilst I was up in SA!
