Incorporating HDR tonemapping techniques with long exposures
The following images were experiments using HDR tone mapping techniques combined with the effects of long exposure times.
Each image was constructed from at least 3 separate exposures using in-camera auto exposure bracketing. In my case, being a Canon shooter, I used 3 exposures of -2,0 and +2 simply for convenience. I believe Nikon shooters have a bit more flexibility in this area.
The images were all taken during daylight hours so it was necessary to use some heavy ND filtering in order to increase the exposure times and achieve a nice misty look to the water. In my case I used an ND400 and an ND8 filter stacked together to achieve this.
With the camera set to aperture priority mode I adjusted the aperture and filter combination (sometimes removing the ND8) to achieve an exposure of 8 seconds. When the shutter button is depressed the camera would then give me 3 exposures at 8 seconds, 2 seconds and 30 seconds (which is close enough to 0,-2 and +2). My particular camera doesn’t let me expose for longer than 30 seconds unless I go to bulb mode and use a remote timer, so out of laziness I tend to limit many of my exposures to 30 seconds. 🙂
The exposures were then combined and tonemapped using HDR software and tweaked in Photoshop to achieve the end result.
Despite all of this sounding a bit technical it’s really quite simple and I encourage you to try it. The results are often very rewarding.

Daytime experiments with the ND400 filter.
The following long exposures were taken during daylight hours using an ND400 and ND8 filter stacked together on the front of my Sigma 10-20mm lens. The combination of these two filters attenuates so much light that peering into the viewfinder reveals an inky blackness even during bright daylight conditions.
It’s therefore necessary to compose the image BEFORE screwing the filters onto the lens. It’s also necessary to adjust the focus manually since the auto-focus system has no chance of working under such conditions.
*** (Update October 2012) The introduction of “live view” to many DSLR cameras means that is’s no longer necessary to compose and pre-focus with the dark filters off the lens. I shoot all the time now using live view to peer through the combined darkness of an ND400 and ND8. The filters now stay on the lens which means there is a lot less fiddling around. If you’re looking for a guide to show you how to use an ND400 have a look at my recent blog post here.***
I found that if I set the ISO as low as possible, and set the aperture very small (i.e. a high number), then it was possible to obtain a shutter duration of about 3 minutes. Such long exposures during daytime create some interesting images. I’m looking forward to experimenting more with the ND400.
The trip to Point Lonsdale
The following are a series of images taken at Point Lonsdale at high tide.
Initially we went there in the middle of the day to try out some “black glass” ND400 filters. The idea was to shoot some daytime long exposures of the low tide water interacting with the exposed rock shelves. Unfortunately I felt a bit disappointed by the results, not because of the ND400 filter but because I had trouble finding satisfying compositions.
Upon returning to Point Lonsdale at sunset the tide was high and there was a bit more foreground interest and some colour in the sky. I managed to find these images a bit more satisfying.
An Evening at Spray Point, Blairgowrie.
The following images were taken on an evening excursion to Spray Point / Montforts beach, Blairgowrie.
I’m never really sure where one beach ends and the other begins. 🙂
Tidal Trickle (below) was taken just prior to the sun dropping below the horizon giving some nice pinks in the sky.
Friends and Fatalities (below) is a long exposure shot taken just after the sun had dropped below the horizon.
The extended exposure time makes the moving water take on a misty appearance and blurs the clouds whilst the foreground rocks remain in focus.
The Unpredicted (below) is a long exposure shot showing water flowing off the rock plateaus after sunset.
Despite the deceptively calm appearance of the image this is really a potentially treacherous area with unexpectedly large waves occasionally sweeping across the plateaus.
Images from Koonya beach
These images were taken on a recent dusk excursion to Koonya beach on the Mornington Peninsula in Victoria, Australia.
Dusk is my favorite time of day for shooting, ……it’s certainly MUCH more user friendly than that other time of day, …….what do they call it, ….”dawn” or something like that. 🙂
Visiting Silverband Falls, the Grampians.

Deep in the Woods
Fog blows across an otherwise sunny section of Mt.Difficult Road near Halls Gap, Australia.

“Changes” – an autumn fog landscape
“Changes” was taken on a foggy autumn morning on farmland in Cranbourne, Australia.
The lush green grass is such a contrast to the dry barren earth found on this spot during summer.

Close of Day
The sun sets over mountains west of Neerim, Victoria, Australia.

Flying Solo – exposure after sunset
This image was taken at Sorrento beach shortly after the sun had dropped below the horizon.
The long exposure (30 seconds) smooths out the motion of the waves and gives the ocean a smooth, almost cloud like appearance. The pink hue is a remnant of the sunset.

Autumn’s New Mist – a mountain landscape
The sunsets near Neerim, Victoria, Australia as a typical autumn mist engulfs the local mountains.

Glide – the salt spray effect
This sunset image taken at Blairgowrie beach, Australia, turned out to be much softer than I expected but I like the final result. The softness of the image is due to a build up of ocean salt spray on the lens filter.
