Florian Schulz takes wonderful photographs and from what I have heard, is a very hard worker, who expends a great deal of effort to capture his subjects. I have his books "Yellowstone to Yukon: Freedom to Roam" and his book "To The Arctic" which is the companion text to the IMAX film of the same name. I thoroughly recommend those books, particularly "To The Arctic" which has some breath-takingly beautiful photographs.
However, this is one Florian Schulz book you should skip. The pictures in "Journey to the Arctic" are virtually all, if not all, recycled from the companion text to the IMAX film "To The Arctic". Nearly picture for picture, the photographs in this book are the same as those in "To the Arctic". Some are simply re-cropped or re-cropped and reversed (e.g the picture on page 30 of the musk oxen in "Journey To The Arctic" is a re-cropped and reversed version of the picture on page 27 of "To The Arctic"; the picture of the polar bear adjacent to the tile page of "Journey To The Arctic" is a re-cropped and reversed version of the picture on the title page of "To The Arctic", etc.).
This book is noticeably smaller (8.5" x 8.5" versus 15.5" x 11") and less lengthy (80 pages versus 212 pages), than "To The Arctic" with a fraction of the photographs in "To the Arctic".
The text is different, but that is not likely why you are purchasing a book like this.
In short, purchase To the Arctic and you will have every picture in this book, plus many, many more in a larger, better format. I love Florian Schulz's photographs and his work in "To the Arctic" is tremendous. It is disappointing, however, that either he or his publishers chose to try to "double-dip" by recycling content in this manner.
