There is no HDR at all - took it in mRAW, developed in Lightroom 4.1 and then some other corrections in Photoshop CS 5.
Do you use DNG? If so, I would completely avoid mRAW. The conversion process makes the files bigger than RAW once converted to DNG. Lossy DNG is flawless, 50% file size savings, and even at 1:1 and closer I can't see any difference. Even pros here can't tell the pick them apart at 1:1.
I was shooting mRaw for a while when I had a 50D a ways back and was doing DNG workflow (still do,I love DNG) and I noticed after a while my sRaw files were 30% bigger than if I just shot RAW. DNG typically gives me a 20% file savings over RAW, and it was 20% bigger. I started just shooting RAW only and will never touch m/sRAW.
