We visited New Zealand in 2019. What a great place for IR Photography!
At this time I had a Nikon D100 with a Sigma 28-300 Zoom F3.5-6.3 Lens converted to IR 630nm.
Here are examples of images using the converted camera at 630nm which gives blue foliage. These images can be great when the Red and Blue channels are swapped. THen the sky becomes blue and the foliage shades of yellow/orange.
When using the 830nm Filter the images are just the same as when shooting IR on film giving the expected dramatic Black and White images.
