Does anyone have experience with using UNMODIFIED Canon 5D3 and filters for infrared photography ?
Here are some shots I did with the 5D3+17-40mm f/4L+Hoya R72 combo.The Invisible Spectrum

I would say that the workflow with an unmodified camera is quite tedious due to the long exposure needed for every shot.
But it's fun as it slows you down to think more about composition unlike the IR modified camera wherein you can shoot anything on sight at once without the need of a tripod.
For the above shots, the WB was set to a predefined custom WB based on the foliage and post-processed via a custom profile on ACR then futher tweaked in CS6.
This maybe a bit off topic but the Hoya R72 has a 720nm cut-off and it is not as flexible as what a 660nm or a 590nm filter cut-off can do. Here are some of my examples from my old IR Modified 20D with a 590nm cut-off for comparison:Final Fantasy
