The Grandfather Photo

Photographer’s Note

So far I have shown you geothermal features that exhibited mainly red or yellow colours. Today it's the green effect of Lake Ngakoro.

Ngakoro translates as The Grandfather. The strange green water of the lake is caused by the presence of sulphur and ferrous salts.
The lake was formed by a volcanic eruption more than 700 years ago and it is still geothermally active. The pale colour at the bottom of the picture is water entering the lake as it comes down a small waterfall from Frying Pan Flat.
The wide range of colours in the Wai-o-Tapu thermal area is due to different mineral elements:
Green -Colloidal sulphur/ferrous salts
Orange -antimony
Purple -Manganese oxide
White -Silica
Yellow-primrose -Sulphur
Red-brown -Iron oxide
Black -Sulphur and carbon

The so called “rotten egg smell” is associated with hydrogen sulphide.

Bonjour Klaudio
Un beau cliché de ce lac aux couleurs incroyables. J'habite sur la cote d'Emeraude mais aujourd'hui le lac peut porter ce nom.
Merci pour le partage et bonne journée.

Hi Daddo,

I missed the blue! from our good 'old blue lake. I really like the PoV and the compo very much. The inclusion of the ridge to the right and the rocks in the fg is a good trick.

I attempted to fix the chromatic aberration on the rocks in the workshop.

Cheers

Hi Klaudio, a wonderful color for a lake. Thank you for sharing these shots from Wai-o-Tapu thermal area which I've never heard before. How was the weather there, very humid or not?

Hi Klaudio,
Wide angle shot of this thermal pool is impressive even though this place looks peaceful, without visible vulcanic activity. Fun to see such beauty of chemistry. Thanks for the explanatory note.

Hi Klaudio,
Incredible colour in this lake, NZ is such a fascinating place, especially in the Wai-o-Tapu area. I like your composition, a perfectly balanced frame with just enough foreground to make the shot more interesting to look at. Great sky.
Interesting note to accompany the shot.
Regards
Peter

Hi Klaudio.
Magnificent expanse of green surrounded by rocks, pebbles, trees and sky. The viewpoint was certainly well chosen, with the little pebbly beach adding interest to the foreground. Clouds are well defined in what I imagine was not an easy exposure in the bright light and the reflection of it by the water and rock. Thanks for the explanation of that pale cloud in the water.
Regards,
Andrew

Zdravo Klaudio, kako si :) ?
I'm back after a long absence... I almost feel envious to see you've made journey in New Zealand, beacuse I dream to visite NZ since I was a child. This place is as much beautiful, as I think...Wonderful wide-angle shot, despite I prefer to see a more upper version.
Your Photographer's Note was very useful for me, because I discovered a green lake in Bulgaria this summer, and I didn't know the reason of this strange colour.
Pozdrav, Silvia

Hello Klaudio, this colour which this water mixed with sulphur and ferrous salts composes accentuates the feeling to be opposite a rare landscape, here the effect is very beautiful, but I very recently saw image of a volcano the Piton of the Furnace, which to spit of the thousand of cubic meter of lava, it with covered several primary education drill on nearly fifty meters thickness, nature it is beautiful but the man is nothing vis-a-vis the eruption and other cataclysms, very beautiful photograph, and an instructive note on various metals, sincerely ..................Hello Klaudio, cette teinte que compose cette eau mélangée au soufre et à des sels ferreux accentue la sensation de se trouver en face d’un paysage rare, ici l’effet est très beau, mais j’ai tout récemment vu des image d’un volcan le Piton de la Fournaise, qui à cracher des millier de mètre cube de lave, il à recouvert plusieurs foret primaire sur près de cinquante mètres d’épaisseur, la nature c’est beau mais l’homme n’est rien face au éruption et autres cataclysmes, très belle photo, et une note instructive sur divers métaux, bien amicalement

Hello Klaudio
Was wondering about the green colour of the lake, before I read your note. Not much visible volcanic or geothermal activity on the surface. Thank you for posting pictures from this place & also your very informative note. Good work!
