Show SNAPSHOT GUILDS PROPER EXPOSURE 'MtJl Brilliantly lighted beach subjects, with no harsh shadows, take less exposure. For this, 125atf.16 (or the large lens opening on a box camera). If subject faces sun, or for a "long-shot" beach view, use f.22 or the small lens opening on a box camera). A ,1 ANY writers make a great to-do about exposure, so that it seems complicated. As a matter of fact, for most ordinary subjects out of doors, it is simple. Light in very early morning or late afternoon is quite weak, but from an hour or so after sunrise to about an hour before sunset, it is fairly constant in its intensity. During Dur-ing the middle daylight hours, camera cam-era loaded with chrome type or "pan." type film, set your lens and shutter as follows: Brilliant day Average subject, 125 second and f.ll lens opening. Open landscape, 125, f.16. Water or beach scenes, 125, f.22. CLOUDY BRIGHT DAY Average subject, 125, f.8. Open landscape, 125, f.ll. Water or beach scenes, 125, f.16. DULL DAY Average subject, 125, f.6.3. ..... ,...i..t..,uuujjajJJMA Open landscape, 125, 1.8. Water or beach scenes, 125, f.8. When you must use a high shutter speed, use a larger lens opening. Remember Re-member that 125 second at f.ll is the same as 150 at f.8, and about the same as 1100 at f.6.3 or 1200 at f.4.5. Follow these exposures this spring and summer, and you won't go wrong. If you use a box camera, take snapshots on bright days only. On a dull day, place the box camera on a firm support and give a very short time exposure (one-half to one second, sec-ond, or about as fast as you can work the shutter when on "Time") using the small lens opening. With any camera, when you are taking pictures shortly after sunrise or before sunset, you must use a larger lens opening, or a slower shutter speed. At such times, light tends to be yellow and the "pan" type film wil! be best as it is definitely defi-nitely faster in such light. John van Guilder |
