World-renowned professional nature photographer, writer, and adventurer Ian Plant has been photographing our natural world for almost twenty years. Ian is a frequent contributor to and blogger for Outdoor Photographer Magazine, a Contributing Editor to Popular Photography Magazine, and a monthly columnist for Landscape Photography Magazine. Ian’s work also appears in many other books, calendars, ad campaigns, and magazines available worldwide. Ian is the author of several dozen books (in both print and electronic format) and instructional videos, including most recently the acclaimed Visual Flow: Mastering the Art of Composition, which spans several centuries and different artistic media in its quest to reveal the composition secrets of the great masters.
There is a growing trend among photographers (especially landscape photographers) to engage in extensive image manipulation in Photoshop, turning rather ordinary photographs into something "magical" using computer wizardry (such as replacing skies, extensive color toning to simulate remarkable lighting conditions where none existed, adding rainbows, etc.), too often made without any disclosure to the public. I do not belong to this trend. I consider myself a photographer, not a graphic artist, and as such I rely on field technique (and a lot of patience) to capture real stunning natural events. Call me quaint, but I believe the magic is found out there, not sitting in front of a computer!
