Here in New Zealand it is mid-summer and this recent image was taken in around 90 degree fahrenheit heat.
The mountain is Mt Cook, New Zealand's highest @ over 12.000 feet and the lake is Lake Pukaki.
Photographed mid afternoon when the reflection was just appearing in the lake.
Pentax K10D 400 ISO 1/4000 @ F4.5 Minus 0.5 EV Multi Segment metering.
Comments appreciated.
