A 10 x 14 piece contrast that rarely results in pleasing Because of the harshness of direct sun, of mat board will make four 5 x 7 inch photos. The sun is, however, a free light source that can be harnessed and utilized in a number of resourceful ways to provide some unique lighting effects. Keep in mind that the sun will never be directly overhead between the months of October through February, which is mushroom season on the West Coast. During those months, the sun follows a shallow arc in the southern portion of the sky. Depending upon where you place the camera in relation to the subject, you can have either direct lighting (coming over your shoulder and directly striking the front of the subject), side lighting, or back lighting. By utilizing some homemade lighting accessories, one can have the effect of a “mini field studio” without requiring a Figure 1. 40 FUNGI • Volume 5:5 • Winter 2012 positions the camera so that the subject/ mushroom(s) is between the camera and the sun. In this configuration, the sun is striking the back of the subject(s) and the reflectors are bouncing the sun light back on to the front of the subject(s). This lighting setup uses the sun as a rim light or back light and will have the effect of visually separating the mushroom subjects from their background. The downside to using this setup is that it obviously limits the scope of available compositions. The best shot of the mushrooms may very well not be the one where the sun is directly behind them. Another style of reflector that can be very effective and more simple in design is a piece of white mat board between 11 x 14 and 12 x 16 inches in size that has a hole cut in it sufficiently large enough to permit one's camera lens to protrude through the opening. The hole should be placed in the middle of one of the dimensions a few inches from the edge of the board. In the same manner as with the small reflectors, the subject is oriented with the sun behind it and the composition is setup with the camera mounted low to the ground. The hole Figure 2. in the mat board is slid over the lens with the white surface of the reflector reflectors and a 16 x 20 inch piece will or a pair of ice cream sticks, glue them facing the subject. Using a free hand, make four 8 x 10 inch reflectors. One to the back side of the reflector and the reflector is tilted and angled so as to can also apply tin foil to the reflector to sharpen the other end so it will stick direct reflected light on to the subject increase the amount of light reflecting in the ground. You should have at least (see Fig. 2).
