Here's a small contribution from a walk in the park in May. Using my converted E-M5 (to 720nm).

It's been a long time since I've seen the Soren Larsen, (I sailed on her in 2000) even longer than seeing the Sydney opera house (2008).
Nice to see them both together - this brings back loads of memories

Are you using a lens filter? How did you use such a fast shutter speed. Mine takes a one-minute exposure.

It's a converted full-spectrum E-M1 Mark I from Lifepixel. I do use various filters, but right now I favor the Blue+IR filter from Lifepixel on it. I just ordered second one in 37mm size too for that lens as I was using a larger 72mm one and stepping it down or up as needed fo whatever lens I was trying like faster f/1.2-2.0 primes. I like the smaller size of the E-M1 with the 14-42mm f/3.5-5.6 EZ zoom lens that seems to be permanent on it now.

The Olympus 14-42mm f/3.5-5.6 EZ zoom lens was at f/3.5 to avoid any hotspots it might have, and shot at base ISO 200. Using that setup with a Lifepixel Blue+IR filter the speeds are pretty high. With the full-spectrum, and them removing the cover filters over the sensor (It looks like just clear glass is over the sensor.), the speeds go back up to about that of a normal camera. The red IR filters below 720nm are also pretty quick on that camera, but above that the speeds slow down a bit but still hand-holdable speeds.

I also set the camera to shoot three high-speed bracketed exposures at +/Norm/- 0.7 EV in Matrix mode too which seems to work out pretty well for me. Seems that I prefer the curve in FastRawViewer to drop to zero about 1/3 stop before their 3 EV over-exposure grid mark.

I've been using ON1 Photo RAW 2021 for post as it has a Color IR Swap, B&W IR, Vivid Blue IR preset, along with some other colors, in their Effects > Filters > Channel Mixer selection.
