Description

An HDR composition of 29 exposures, from 1/3200 sec to 4 sec. Processed with Photoshop and a program written by myself. Taken in eastern Oregon, near Prairie City.

Ver.B is one of the intermediate stages of the processing. I found it visually appealing in some way, so I upload it here. It is a gray-scale HDR image, generated from the many exposures after bias and flat field correction. It is used as the luminance layer in the final blend, as it shows accurate brightness changes because of the calibration. On the other hand, there is another set of HDR image produced from the Photoshop-converted raw files, without bias and flat calibration. This set has better color because of the Photoshop conversion. It is used as the color layer in the final blend.
