Re: IR conversion - Was: wannabe

If you are rich, you should look at the Leica M8.  There is no IR blocking filter on the sensor and it works great for IR photos.

Interesting response, thank you!


Yes, definitely some heavy experimentation is in order. I just read that early in the morning there is more natural IR, so I am very affraid I will have to be on the field so early. ;)

Basically, I am competing against myself - the filter gives me the IR, while the unmodified sensor in the camera tries to block it - I hadn't thought of this and it totally explains the steep compensation factor. It definitely turns the scale for me in favor of permanently modifying the digital body instead of buying a filter!

I now have two arguments of reason - I am rich!
