Jan 26 – Tasman Lake and Glacier, New Zealand
It stayed pretty wet and overcast all day, making the view over the Tasman Lake rather dull, but spectacular nevertheless. The Tasman Glacier to the left of the lake is the longest in New Zealand at around 24km. You can see the white icy top of the glacier further up the valley, while lower down by the lake, it is covered in dark rock debris.
This whole area is in the Mount Cook (Aoraki) National Park – Mount Cook itself (NZ’s highest peak at 3,724m) is behind the clouds to the left of both images. Fortunately, I got better pictures of that snowy peak a day later. The glacier feeds in to the Tasman Lake, which then flows down the valley as the Tasman River, before flowing in to the wonderful Lake Pukaki. At the higher levels, the waters are filled with glacial rock flour, which gives this very milky appearance. Lower down the valley as the flour settles, the waters become the greener turquoise or the bluer aquamarine, which is exactly what makes Lake Pukaki so spectacular.
This first image is a panorama of five shots taken on my Z 24-120mm f/4 S lens at 24mm, f/9, 1/100s and ISO 100, giving a final picture that is 18,100 by 4,900 pixels, ie 89MP. The first snows of autumn had happened overnight, which significantly improved the image, although much was lost in the low cloud. I was expecting the glacier to have retreated a lot since our last visit in 2019, but in comparing my photos, I couldn’t really see any huge difference. I believe the ice front has been quite stable for a few years now, whereas it was retreating by around 600m per year back in 2015.
The second photo is zoomed in to the glacier front using 120mm, f/10, 1/100s and ISO 100. The blue ice is now very apparent on the glacier wall, as are a small number of icebergs in the milky waters of the terminal lake.
Both pictures used a WB of 6,500K, together my usual range of adjustments in Lightroom, particularly to enhance the colours a tad more, and to dehaze the low cloud areas.
Jan 26 – First Autumn Snow, Tasman River Valley, New Zealand
I have done very little photography since we were in New Zealand last spring, as my hip had gone arthritic very quickly and it took a good few months to get a hip replacement, which then took quite a few months longer to recover. The net result being that for the last 6-9 months, I couldn’t either walk far or sit at my desk for long to do any post-processing. Anyway, I’m just now finishing off the images around the mountains and glaciers of Mount Cook.
These two photos were taken in the Mount Cook area, as we walked up to the Tasman Glacier and Lake. It was very wet and stormy, and the first snow fall of the autumn had occurred overnight on the higher peaks around the Tasman valley. Both were taken on my full-frame mirrorless camera, the Nikon Z 7II, using the very versatile Z 24-120mm f/4 S lens, which is great for travel and landscape photography.
The first photo was at about 10am looking up towards the snowy mountain peaks at 35mm, using f/9, 1/125s and ISO 125. Surprisingly, even though it was very cloudy and overcast, the light was unusually bright at around EV 13, which is only two stops down from a sunny day. I love the contrast between the moody sky, the snowy mountains and the bright yellow autumnal grasses.
The second shot is a panorama looking back down the glaciated Tasman River and valley. This was formed from two 24mm images merged in Photoshop, and both taken using f/9, 1/100s and ISO 125. The beauty of this next generation of mirrorless lenses is that they maintain their sharpness throughout their zoom ranges, which was not always true of the F-mount DSLR lenses.
