An HDR panoramic image spanning two levels inside Luray Caverns, Virginia. Created from four sets of five exposure series, with a 2 ev. spacing, the HDR images were toned and stitched as a 32 bit depth image inside Photoshop 5 and saved as a "radiance" file. Photomatix 4 was used to tonemap the final result. Further touches in Lightroom 3.
