Amazing colour in the sky during this long exposure at sunrise over the Brisbane River near Ipswich Queensland Australia

Brisbane River Long Exposure

My plan this morning was to head to a new spot for me on the Brisbane river, not far from Ipswich. The clouds early were moving quite fast but the wind at ground level was almost non-existant. I started thinking a long exposure might be something to try.

Arriving at the parking location I began the walk down to the river. The first part of the track was pretty easy, patches of gravel and not too steep. That soon changed when I was confronted with waist high grass before the river. Plowing on (literally) I finally arrived at my location 10 minutes later, drenched from waist to toe, ahh the joys of landscape photography.

There was some colour starting to appear in the sky so I had to make some decisions quickly. The texture of the clouds was messy, so I decided, super long exposure to make things super silky. I would use a polarising filter to remove some of the glare from the water (this also has the effect of adding around 1.5 stops of exposure time. Next I would add a 10 stop neutral density filter to give me some very long exposure times.

With the filters off the camera I set the camera in to manual mode, set my focus where I wanted it, I put the aperture at F8 which ensured me everything would be in focus and give me an extra long exposure time. ISO kept at base 200 for best quality.

Now it was time for another trick built into my Olympus OMD Em5 Mark II camera. This feature is called “Live Time”. You press the shutter once to start the exposure, and at regular intervals (I had it set for every 30 seconds) the rear screen updates with a photo of the exposure at that time, and updates the histogram. It’s as simple as letting  this run for as long as you want and stopping it before it starts to over expose. I always have long exposure noise reduction enabled, the time it takes you extra in the field (essentially doubles your exposure time) you save so much more in post processing trying to fix the noise.

This photo ended up taking 8 minutes of exposure time and 8 minutes of noise reduction time. So it was a one shot while the colour lasted in the sky.

There has been very minimal post processing done to this photograph. A little bit of contrast added and some colour pop was all that was needed.

I took a few more shots as the light got brighter. I was really hoping the sun would break through and throw some direct light on the trees on the far bank but it was not to be this morning. I did like the smooth results I was getting however, and found the tree trunks were contrasting very nicely against the green vegetation. I ended up converting this photo to a very simple black and white.

With the bouts of wet weather and cloudy conditions we are having here at the moment, I will be exploring long exposures a little more often I think, the results are quite lovely.

A stunning sunset over Lake Moogerah in the Scenic Rim of Queensland Australia. This panorama shows the beautiful wide view of the dead trees in the water, with Mt Greville looming in the background. The sky is full of colour and the ripples of the water reflects this wonderfully.

Lake Moogerah Sunset Panorama

G’Day everyone. With the family all off to see Mamma Mia the musical, I ended up with a free afternoon. There was a meetup for the Scenic Rim Photo Walks group at Lake Moogerah, so all the gear was packed and off I set for the hours drive south to the dam.

It was a very hot and warm day, many people were taking advantage of the lake with jet skiers and water skiers zipping around. The clouds was starting to look very good as sunset approach, but the wind in the main part of the lake was still very strong, it didn’t look like I was going to get one of those perfect reflections.



I decided to head around to the southern part of the lake as it appeared the wind was a little less strong there. Driving down to the waters edge it looked like I was right, it wasn’t a mirror finish, but the ripples were nice and I figured that if there was colour for sunset, this could work.

I walked the shoreline trying to visualise for a panorama, not something I do often so its a little hard to get your head around. I ended up using my phone to take photos, and then crop them in phone to a rough 3:1 aspect ratio to help work out my composition. There were two stumps close to shore, I liked those and wanted them as my foreground interest. Two sets of taller trees on each side of the mountain could work as a nice framing element. After about 20 minutes of moving around I settled on my spot.

I had my tripod as low as it could go, I also had the camera mounted on a nodal point setup in portrait orientation. This basically allows the camera to rotate around the best part of the lens, so when you get back to stitching together the shots, you have very minimal loss of pixels, worked out great. The hardest part is to make sure your tripod is dead level.

I zoomed in to 34mm on my Olympus 12-40mm pro (equivalent to 68mm on a full frame camera). I wanted to bring all the elements of the scene closer to each other. When you are standing there, that mountain really looms over you and with a wide angle, that feeling would have been lost. I put the camera in full manual mode, ISO at my lowest which is 200, Aperture at F9 which gave me just enough depth of field being zoomed in (take a few test shots and check the sharpness on the back of the camera to get this right). I was also going to bracket my exposures as with such a high peak, using a filter would have darkened it down too much for my liking. My camera is the Olympus OMD, Em5 Mark II.

Now it was just a matter of sitting back and waiting. Sunset here in South East Queensland Australia can be a very funny thing, you will get waves of colours and just when you think it’s all over, another blast comes through. After witnessing at least 2 bursts of colour that didn’t light up the scene well, I thought this may end up a dud sunset, but I knew I something could happen so I just waited.

Suddenly the cloud to the right started getting a hint of red, and within 30 seconds it was glowing. I took my shots from right to left (starting where best colour was). 6 vertical shots overall to capture the width of the scene I wanted, 3 exposures for each shot at metered exposure, 2 stops under and 2 stops over. I ditched the underexposed photos as my metered captured the sky perfectly. Here are the final 12 exposures I would work with.

These are the initial exposures I will use to blend, stitch and then post process to create my Moogerah Sunset Panorama.

The colour finally finished so I made my way back to the day use area to meet back up with the group. I captured a great star trail shot which I’ll share up next week with the details on that one.

Post processing this image was going to be a lot of work and I actually had several goes at it. I finally decided to exposure blend the metered photo and the 2 stop over exposed photo from each shot, to bring back some of the detail in the darker parts of the middle ground. This involved taking both photos into Photoshop and using luminosity masks to blend. I finally ended up with these 6 photos ready for stitching to a panorama and then post processing.

Now the post processing begins. I created the panorama in Photoshop and then began my adjustments. I did some colour correction to get the colours to where I remembered them. I then used Nik filters to boost the contrast and colours. A final round of sharpening and I was very happy with the result. The final image ended up at 40inches wide at 300dpi, I’ll certainly be able to print this very big.

I really enjoyed the process of capturing this panorama, and I’m starting to learn how to visualise the shot. I’m looking forward to repeating this process more this year, keep an eye out!
