These images are from the process. Here are the threads on DPR that I followed with more detail first thread to remove the hot mirror and second showing how to get under the hot shoe.

The hot mirror that I removed is the "red" glass here. It is actually cyan when removed, the red is a reflection. From the first instructions, I thought I could remove the mount here, but the screws were threadlocked with something, so in the end I broke the glass to extract it. It's easy to do this accidentally I think since the glass is only 1mm thick. Then just peeled off the rubber glue. Obviously, this is not reverseable

And finally some DP1m images. First, before modification:

After modification and custom white-balance, full spectrum results! I made some exposure/contrast tweaks to the images below, but no channel swapping or large hue adjustments. It looks like these out of camera with no filter. One big benefit of modding this camera compared to an SD is you can see the IR results in live view. Adding various color filters and infrared filters can yield different looks.
