I have used jetpack to improve the experience with seeing photos in galleries, and this has allowed me to increase the size of photos here. The full size photos are 4000×3000. Be aware that if you download the full photos they are around 8 MB big.
All the shots were taken with a 21 mm Nikkor E lens. The organ pipes are just below the summit of one of the hills around Dunedin. My son took my 50 mm lens and put it on his DSLR. We left the zoom lenses in the car.
