I recently converted a cheap, partially broken, E-PL1 to be full spectrum sensitive by removing the filter that cuts UV/IR light. Despite this being a relatively cheap and old camera, the 12-ish megapixels combined with the razor sharp 25mm (50mm full-frame equivalent) honestly delivers plenty of detail.

I love how the sky is grimly lacking IR. Nothing much to re-emit IR up there.
Yeah it’s so cool. Honestly, IR is the dream for black and white landscapes: foliage is bright white and the sky very dark. Scenes like these can sometimes look very mundane on a normal camera, and then look absolutely stunning in infrared
