Did some reading, bought a filter, ready to practice. Could any of you experienced hogs suggest an exposure triangle as a starting point for my learning curve?
Thanks.

My camera was converted so no filter and I can’t really comment except to say the exposure will be long most likely. Hence you need a tripod.

I would set up the the camera composition, focus and then put on the filter and set the exposure which will be long.

What filter are you using (nm)? When I used a 950nm filter, exposures were around 10 seconds f/8 ..100 asa.

Also consider setting Custom WB w gray card/green grass in similar light - otherwise image on back of camera will be very red and hard to evaluate

Before I convert one of my camera to full spectrum IR, I used to putting a IR filter in front of my camera for IR imaging, I used 720nm ( a good choice to start IR photography), My general setting were ISO100; shutter speed around 1-2sec at f4.0; pre set WB. using tripod and remote shutter release, using the lcd screen for focusing, (all should be out door in bright Sun light). Now I can take any IR photo with different IR filter by normal setting and AF like using normal camera after camera converting.
Good luck!

Here's one sample taken with the 720nm filter with a non-converted camera, and did some color management on PP.

Welcome to digital Infrared photography ... I think. Did you remove or replace the internal filter over the sensor?

You did not state this, so I am uncertain how to advise you any further, though I see others have already, all assuming you have not done so. That’s fine, of course, but to me and I would think most others who have had their cameras actually "converted," you are employing what I call the Brute Force approach. This approach is somewhat analogous to driving a car with the emergency brake deliberately applied and depressing the gas pedal (aka accelerator.)

I'm having an older model Sony RX100 converted to use gentile force, but in the meantime I'm about to wander around with a tripod, filter, and Oly. Thus, the question.

"gentile" force? Was that a Freudian slip?

Regardless, is your "Oly" a mirrorless camera? Does it have an eVF? I ask because this can have an effect on how you acquire your images and I don’t know what you’re level of understanding is.

Siri + no editing=😢
I’m experienced, or advanced, or some such adjective.

Okay, I presume that your not answering my 2nd & 3rd questions directly is consistent with such experience. Have fun!

Go to search at the top of the page and search IR you will find the subject has been well covered.
Often using Auto is safe bet for exposure... at least it gives you a start for adjustment manually. White balance is critical. Filters in the 600 nm region give shorter exposure.. 720 is of course true IR giving BW image... beyond that takes too long to expose. Exposure is similar to photographing the night sky if that helps you in setting the exposure.

I converted a low-cost camera which required only 6 shell screws and 3 sensor screws. Then attach a 37mm filter thread and you have a fun IR camera for full spectra range. The mix of IR and tale of visible makes it interesting... mixing a bit of color. The conversion is simple and covered in my topic:

Which filter is covered in
https://kolarivision.com/articles/choosing-a-filter/

IR is a have-fun-thing and typically a now and then adventure... usually not worth the converting of an expensive camera. My conversion camera was under $100 and can be found for 50 easily. A simple $10 screwdriver set will do the trick. Make a drawing of the shell so that the right screw goes in the right hole. [at least one screw will disappear on the floor ... oops]
