These storms don't even seem to bother birds, if it did, they would just fly south. I love weather images, the heavy snow may decrease image sharpness but that's the nature of the beast. Remember, you need light for both our eyes and for the camera's to see detail. Tip: To understand how shutter speed changes go outside in daylight hours and raise your camera into the sky, notate how quickly it will drop as you lower it toward the ground. This explains why images that fall low to the ground or with dark backgrounds often lack sharpness. You may have good shutter speed 30 feet above ground but when the birds cross water or land low you don't have enough to freeze the image. Shooting on shutter speed priority will help assure that you maintain a steady shutter speed, the f stop aperture will adjust accordingly. Of course, there's always limitations like if your f stop has reached its maximum such as 5.6. Shooting on aperture priority guarantees that you always maintain the same depth of field, the shutter speed will adjust accordingly. There's always limitations to shooting in this mode also. I rarely run my ISO/film speed over 320. Higher speeds will develop noise in the images, (noise, noticeable grainyness) while the digital camera manufacturers claim they have gotten a grasp on this, the noise becomes noticeable when cropping or enlarging an image. Not much concern if you keep pics in 4x6 format. Easiest photos to take guaranteeing high shutter speeds is those looking into the sun at dusk and dawn giving the silhouetted only appearance of your subject. These are some of my favorite photos. I have been asked on several occasions for permission for use of my images, I would love to do that. All of my images are the sole property of Avery Outdoors. Hope you enjoy the pics.
