Painting by wind
In the previous post I claimed that our lakes are too small to create any real wave action to allow smoothing out the water with long exposures. Well, sometimes it pays to challenge the conclusions I jump into without having any real facts at hand, so today I headed to one of my favourite locations (or as I decided after I came back, the favourite location) while the wind was blowing at its best. I was right on the money about the one second shutter speed though, but I was able to go slower by overexposing to the point of blowing out the highlights and trusting Lightroom to recover them for me (which it did).
So, the discovery I made about the waves is that size doesn’t matter. All you need is a long enough shutter speed to smooth out whatever kind of waves are going about. But today’s exercise wasn’t really about the waves though, because I was more interested to see if I could get the reeds – or grass – to blur out. So all I needed was some fixed point (a rock will do nicely) and then a lot of grass. And would you know – it worked! Lesson learned, I only wish I had tried this before.
I mentioned that this place is now my #1 favourite. It’s good for flowers and landscape and works in any kind of weather, and today I found out that if I had the patience and/or inclination, I could even try wildlife photography there. I saw something in the water, it could swim and dive and it wasn’t a bird. Could I be so lucky that it was an otter? Or maybe a beaver. Or maybe it was something smaller, it was too quick to make it out properly. In any case, it didn’t make this place look any worse in my eyes!
Sunset
Since it was a windy day yesterday, I wanted to try some long exposures with wind blown objects. I had just the place in mind, a lake with a small island and a rickety old bridge inbetween. It was overcast weather and quite dark, so the polariser and ND8 filters stacked gave me a whopping 25 sec exposure at f16. I was a bit surprised to see the result – the water surface is smooth, but there wasn’t quite as much movement in the reeds as I had expected. The biggest problem with this whole concept is of course that the wind doesn’t pick up speed in these small corners quite the same way it would do in more open spaces. For example if I wanted to smooth out some serious wave action – which I’ve wanted to do for years now – we just don’t get that here. Small lakes.
When I was driving back I noticed that the sky was opening up in the west, just perfect for sunset. It turned out to be just as fine as I had hoped for and I took a whole lot of pictures, although having said that, I was also bracketing with HDR in mind. So many pictures in fact that I had no chance of processing them last night, thus a belayed post. Photomatix had a lot of trouble with these images though, it helped with the sky but the reflection in the water was a nightmare. Completely oversaturated and way too bright in relation to the sky (the reflection is always darker than the thing that is being reflected). So I took the Photomatix HDR creation to Photoshop and added a reflection from one of the original images, then erased with low opacity to reveal just a little bit of the saturated colour in the HDR beneath.
I had hoped to get some more long exposure wind pictures today, but not sure how it will work out now that it’s sunny. The pol and ND filters won’t kill enough light, one second is probably an optimistic target. I’m thinking about getting another ND8 filter for these occasions… I wish there was an ND12 or ND16 though, because I don’t like the idea of stacking three filters. Vignetting is not an issue because I’m using a crop factor camera, but that’s a lot of extra glass in front of the lens. I guess I just have to make sure it’s quality glass, so the Hoya Pro-1 ND8 will probably be in the shopping cart shortly!
