Nice video, thank you Matthew, much appreciated. Definitely a bit to get the head around, almost like starting over, but exciting at the same time from a creative point of view. Thanks again 🙏
Absolutely. It's fun though and it's really nice that the point of entry is just a cheap filter. I've been meaning to do another video of a day out doing infrared. This is good inspiration!
I'm so confused. I was under the absolute impression that to shoot IR the first mandatory thing to do is convert the camera itself and remove the built-in IR filter that sits in front of the sensor. Isn't that so? How can the camera see IR just by adding an IR filter screwed-in the front of the lens of then inside there the camera's own IR filter to block all IR light?
You've got everything right except that the camera's IR filter is not 100%. When we throw the R72 or similar filter on the lens, we are filtering the light spectrum to only 720 nm and higher. Then the camera's built in IR filter lets some of that 720nm or higher light through to the sensor. This is precisely why the same scene will need a much longer exposure and/or higher ISO on an unconverted camera compared to a convert one...because far less light is getting through and we need to expose the scene differently. I'd say you got it! Not confused. Thanks for the question.
Excellent question. You should be able to do the edits on an iphone for black and white conversion. Color inversion should be possible with presents but it might be a bit more challenging. You also can use a filter on an iphone or other mobile device using a couple methods. So yeah, I would generally say that you can do it on a phone!

Deep prime is amazing even for my Sony rx10 4
By the way, I currently live on the road in a nice RV and am doing a photo book on my (9 years) of travel like this. For what that's worth.

My hoya on a 35mm samyang creates extremely strong colored vignette. Any idea what's up with that?
I’m not sure! Are you correcting the images in post using a profile or noise reduction like DxO?
Isn’t it addictive?
can this be done on an iphone?
