After the early sunset

Today, the weather was a real treat. -10C and clear skies, wonderful pastel colors. Two days ago we got about 20cm fresh snow and it all looked like a winter wonderland. I was shooting at the rapids of Koitelinkoski. After the sun set about 2.30pm the afterglow came in and hit the trees for a long while. Beautiful contrast of warm and cold colors.

14 minutes at night

Another long exposure experiment, really love doing those. For this photo the camera ‘looked’ at the scene for about fourteen minutes. Going into about five minutes of this exposure, there was some aurora activity – mostly out of the frame. When I finished this photo, the aurora was basically gone, but I caught a piece of it 🙂

Night at Koitelinkoski


Valoa Koiteli – Candle rapids

Last night the rapids of Koiteli were lit up by countless candles and some light installations. ‘Valoa Koiteli’ is a wonderful event. Lots of families were there and the kids loved to run around with flashlights. The candles created a warm atmosphere – at -8C.

In this panoramic photo (click on it) you can see part of the candles on the right side of the chain bridge. As winter progresses most of the water surface you see now will be covered by thick ice.

For the photo geeks, this panorama is made of 24 single photos and – dare I say – the long side is 35,000 pixels 🙂

Goodbye winter, hello spring!

All leaves have fallen from the trees. Fields and roads are covered by snow. Almost all water is frozen; lakes, rivers and even the Baltic Sea. Birds migrate to the South and other animals are in hibernation, sleeping for months. Days are short and the long, dark nights are sometimes lit by Northern lights. That is winter here in Oulu – for me.

Then, at some point, the river ice starts to melt. The water is getting stronger, washing away big blocks of ice. The silence is broken and from far away one can hear water rushing down rapids. After months of white everywhere, it is a powerful experience, to both ears and eyes. That’s when spring has arrived – for me.

Ice blocks surrounded by rapids, Koitelinkoski.

Yes, spring is finally here. A few weeks back we still had about half a meter of snow. All melted away within a few days of rain and temperatures of +10C and more. Shortly after that, the ice layers of the many rivers started to break free. The strong current pushed ice blocks out of the riverbed and along narrow points, ice damns built up quickly causing floods.

Ice block at Koitelinkoski

Last weekend a friend and I visited Koitelinkoski, a place not far from Oulu. Small islands and rapids lay here in the river Kiiminkijoki. It is always beautiful but at this time of the year, it’s a breathtaking sight. So much water everywhere and ice blocks sitting on rocks. On top of that, slow sunsets and bright nights make great light for many hours.

Enjoying the fantastic view at Koitelinkoski

If you ever have a chance to visit Koitelinkoski, go there for a picnic and grill some sausages over an open fire. And hey, don’t forget your camera.


Quick tip: If you want to get photos with silky smooth water, bring your tripod. The longer your exposure time is, the smoother the water will be. Choose smallest ISO and smallest aperture possible (highest f-number), then adjust the exposure time until you’re happy with the photo.
