Using a Sony A6300 which has been modified to be a monochrome sensor. The lens is an Asahi Pentax Takumar SMC 100mm f4 macro which is capable of a 1:2 macro. The lens was set to f11 to get additional DOF. I will be looking at green Hibiscus flower buds which have not yet opened. Both images were shot in RAW and processed the same way without Demosaicing. PhotoAI was used on both to optimize sharpness. There is also a big difference in background light where it appears that the light must have been mostly visible light, and was not an issue in the IR image.

First image is using a UV-IR cut filter which means that the sensor will only see visible light. Note that the green flower bud Hibiscus is quite dark. I see that my focus was on the left bud.

Second image, the UV-IR cut filter is removed and instead, the camera is using a 650nm IR filter. Green portions of plants strongly reflect IR light which causes the flower buds to look white. My focus happened to be on the center flower bud.

Third image is a cropped side-by-side closeup. What I am seeing is that the fine detail seems to be sharper on the IR image. I have seen this effect before. The fuzz is sharper, and the surface detail is sharper.

Very interesting, thanks for sharing. I've often read about IR but I've not yet tried it. Very nice comparison.
