Michael Clawson is a creative railroad photographer. He takes photos from trains as they climb mountains and come back down into towns, finding inspiration in the sounds of the train whistle. Kodak's Steve Sasson invented the first digital camera prototype in 1975 using a 100 x 100 pixel sensor. Planning is important for train photography, considering factors like time of day, schedules, and lighting. DSLR and mobile cameras both have advantages, and using both allows enjoying benefits of both worlds.
