Their technique is mostly of theoretical interest to me, especially the concept of exploiting the [usually good] correlations between the colour channels (the existence of which makes Sigma’s foveon sensor fundamentally flawed in my eyes)

However I like the idea of shooting in IR with flash, although it has been pointed out to me that this has been done by other photographers already.

Just had a read of their PDF. I disregard my previous comment based on my initial amusement

To be fair there system is clever. But not exactly accessible to anyone else without a modified camera

This is such an incredibly stupid idea.

IR photography is used for forensics as is UV. It shows up details in the sub dermal (or whatever it is) layers of the skins. Bruises, and other exciting injuries. UV produces some really interesting portraits, but none are ‘everyday’ portraits. It shows up veins!

However… this brings us to point two. In order for it work practically you would need a modified sensor as the man says (expensive but doable) so that means for the second high ISO image you would need a separate camera.

Its fine if you have the man above (who looks very suspicious!) who stands still and doesnt move and you trigger both cameras together… but when would you want to use an IR flash? When you don’t want to use a real flash! So that would be events when you want to be discreet. Umm… those types of events do not have people standing still so you can take the same photo twice.

SIGGRAPH - yeah, we all read those conference proceedings! And attend the showing of every short film, too.

Thanks for posting this over on Strobist!
