This photo was taken on Rottnest Isle, Australia in 2019. Because of the prevailing winds the trees tend to bend on the never-ending force of the wind. Rottnest loosely translated means Rat's Nest island. The island was first documented by Willem de Vlamingh in 1696, because of the Disney like animals called quokka. I used HDR, 5 exposures at .07ev. I shot all HDR during my visit. Chlorophyll, the pigment responsible for photosynthesis, reflects near-infrared light while absorbing visible light (particularly blue and red). This strong reflection of infrared light by healthy foliage is known as the "infrared signature." The healthier the plant, the more infrared light it reflects. Because of the dead or drying wood. With some of the tree in foliage and the rest devoid, the light reflected back provided an interesting contrast. I felt the combination of the vivid orange and the contrasting BW made for an interesting image."

Mo, I don't quite understand the procedure you used to create this image. Is this an IR capture and what IR conversion was used on the camera you shot this with? What filter if any did you use on the lens? A color IR image usually shows up with a dark blue sky, so did you convert the sky to B&W? I like this image but wish I know more about how you created it.

I had my Nikon D810 converted to a 590nm full spectrum conversion. 590nm Conversion: Red channel will see infrared and red light. Green channel will see some green and infrared light. Blue channel will only see infrared light. It does allow for some color to come through. Each of the .DNG files were edited in RAW to tweak the clarity and contrast. They were then combined as the HDR with a .07 difference in images.I didn't use any filters.I used the CLIR conversion suite that allows me to tweak certain channels selecting more or less color in each channel. I could have easily have use the blue channel to register more of what little blue is collected. There is a lot of latitude to adjusting tone, hue, etc. Posted: 01/14/2025 23:39:07

Here's something similar of the Asa Packer mansion in Jim Thorpe. Also HDR. Posted: 01/14/2025 23:40:16

An interesting and creative approach to the subject. Your Disney reference in the description is apt as this has the feel of some of the Fantasia scenes. The blend looks clean as far as I can follow the tonal transitions between the colors and the BW areas. I might tone down or remove that one bright tree top just poking above the canopy on the left. I find my eye kept going there. Posted: 01/16/2025 00:30:19

Thanks Rick. That little bit of bright green always bothered me. I see the tree that you are referring. The IR conversion that I have is also referred as super color. SO the amount of chlorophyll affects what the tonal qualities will be. But I still could have made it lighter. Thanks for the comment. Posted: 01/16/2025 00:35:37
