This is the HDR before and after comparison of “Let there be Light (HDR Vertorama)“. The final image was created from 4×5 TIFF files (series of 4 autobracketed RAW images, +2, 0, -2EV that were converted to TIFFs using Abobe Camera RAW with the Five TIFFs method creating additional +4EV and -4EV images). You can see the 12 source images in the left three columns. These images were merged into 4 32-bit HDRs and tone-mapped with Photomatix Pro 4.1 (detail enhancer option) using the same settings for each image. The resulting 4 16-bit TIF images where then stitched using Photoshop CS4. The result of the stitching, perspective correction, cropping, and retouching can be seen in the middle column. In the right column, you see the final image after a number of post-processing steps executed in Photoshop CS4.
