  • Field Trips Guide Book for Photographers Revised 2008 a Publication of the Northern Virginia Alliance of Camera Clubs
    Field Trips Guide Book for Photographers Revised 2008 A publication of the Northern Virginia Alliance of Camera Clubs Copyright 2008. All rights reserved. May not be reproduced or copied in any manner whatsoever. 1 Preface This field trips guide book has been written by Dave Carter and Ed Funk of the Northern Virginia Photographic Society, NVPS. Both are experienced and successful field trip organizers. Joseph Miller, NVPS, coordinated the printing and production of this guide book. In our view, field trips can provide an excellent opportunity for camera club members to find new subject matter to photograph, and perhaps even more important, to share with others the love of making pictures. Photography, after all, should be enjoyable. The pleasant experience of an outing together with other photographers in a picturesque setting can be stimulating as well as educational. It is difficullt to consistently arrange successful field trips, particularly if the club's membership is small. We hope this guide book will allow camera club members to become more active and involved in field trip activities. There are four camera clubs that make up the Northern Virginia Alliance of Camera Clubs McLean, Manassas-Warrenton, Northern Virginia and Vienna. All of these clubs are located within 45 minutes or less from each other. It is hoped that each club will be receptive to working together to plan and conduct field trip activities. There is an enormous amount of work to properly arrange and organize many field trips, and we encourage the field trips coordinator at each club to maintain close contact with the coordinators at the other clubs in the Alliance and to invite members of other clubs to join in the field trip.

  • Potomac Gorge Side 2
    Discover the Potomac Gorge: A National Treasure On the outskirts of Washington, D.C., the Potomac River passes through a landscape of surprising beauty and ecological significance. Here, over many millennia, an unusual combination of natural forces has produced a unique corridor known as the Potomac Gorge. This 15-mile river stretch is one of the country’s most biologically diverse areas, home to more than 1,400 plant species. Scientists have identified at least 30 distinct natural vegetation communities, several of which are globally rare and imperiled. The Gorge also supports a rich array of animal life, from rare invertebrates to the bald eagle and fish like the American shad. In total, the Potomac Gorge provides habitat to more than 200 rare plant species and natural communities, making it one of the most important natural areas in the eastern United States. © Gary P.

  • 46 Pola Negri in 1927
    Courtesy LofC, Prints & Photo Div, LC-DIG-ggbain-37938 Pola Negri in 1927 46 ARLINGTON HISTORICAL MAGAZINE Pola Negri Slept Here? Unraveling the Mystery of a Screen Siren's Stay in Arlington BY JENNIFER SALE CRANE With Arlington having few Hollywood connections to boast of, save For­ rest Tucker, Warren Beatty, Shirley MacLaine, and Sandra Bullock, the story about a modest stone bungalow nestled in the Gulf Branch stream valley off of Military Road is curious indeed. According to a long-held local legend, silent film star Pola Negri once stayed there. Local accounts have varied- some say the house was rented by Negri as her "Virginia hideaway," others think it was built as Negri and Rudolph Valen­ tino's love nest, and played host to Hollywood-style pool parties. The cozy bungalow at 3608 N. Military Road, 1 with quite a few additions and alterations, is now home to the Gulf Branch Nature Center, established in 1966 and operated by Arlington County Department of Parks, Recreation and Cultural Resources. The swimming pool, filled in and planted with a garden, can still be identified by the exposed segments of its curved concrete walls. The Nature Center's connection to the early Hollywood star was investi­ gated in the 1970s by ComeliaB. Rose, Jr., a founding member of the Arlington Historical Society. Rose's documentation leaves a few questions unanswered. But despite the lack of unequivocal primary source evidence, the story of Pola egri and the Gulf Branch Nature Center has become an important part of the oral tradition of Arlington County.

  • Nature Photography
    Nature Photography Front Page | Staff | Instruction | Galleries | Forums | Portfolios | Gear | Links | Membership The Mighty Potomac and Mather Gorge Text and photography copyright © Joe Rossbach. All rights reserved. Separating Maryland and Virginia, the mighty Potomac River takes a dramatic plunge through Mather Gorge in Great Falls National Park. The river drops over 70 feet in less than one quarter of a mile through raging waters and house sized rocks before snaking its way past 100 foot cliffs and into Washington D.C. and then finally the Chesapeake Bay. The scenery in the park is amazing and the wildlife is not so bad either. Come June, the Great Blue Herons return to the park and dazzle visitors with their daredevil fishing tactics below the big falls in Mather Gorge. The park is laced with trails for the adventurous photographer including the Billy Goat Trail on the Maryland side and the River Trail on the Virginia side of the Park. The Billy Goat trail climbs across rugged rocks and steep cliffs bordering the Potomac River and is not to be missed when visiting the Park. In the warmer months, brave Kayakers surf the rapids below the falls and if you’re lucky you may even catch them taking free fall drops over the largest drops. A sight to be seen! Places To Shoot There are a few favorite places of mine to shoot in the Park. On the Virginian side, there are 3 great overlooks that give an aerial view of Mather Gorge. Sunrise is my favorite time to shoot on the Virginia side as you will most likely have the park to yourself and probably get some nice mist rising off the river in the early morning hours.
