Hello Amita You have been shooting in very difficult light. The very low sun is giving you trouble. Believe me, we Scandiavians know this from experience. That' what gives the camera eeposure automatics problems. You uses Av setting, letting the camera chose shutterspeed, but with the flash turned on, the camera will use a minimum shutterspeed, leaving no or just a little "space" for the flash to work in.
Problem: The two first pictures are kind of backlit, causing underexpsure, The two others are partly lit by the low sun, thus better exposure/overexposure. Solution: Use "M" setting and a flash. Make sure the setting will not - even without the flash - overexpose your shots, but slightly underexpose. Let the flash provide the rest of the light needed. If F8, 1/100 gives you slightly underexposed frames, use this setting AND the flash set to TTL. Alternatively, don't use TTL. Use "A" setting on the flash to provide enough light for a sertain Aperture. The flash will then cut off the light beam when it has reached the sufficient ammount. Set the camera accordingly or one aperture darkier to use the flash as fill in, not main light. And - BTW - don't use F3.5 for portraits. Use F5.6 or better. All the best Jens mailto:[EMAIL PROTECTED] http://hjem.get2net.dk/bladt -----Oprindelig meddelelse----- Fra: Amita Guha [mailto:[EMAIL PROTECTED] Sendt: 7. november 2004 02:42 Til: [EMAIL PROTECTED] Emne: fill flash problems on the *istD Last weekend, we shot a bunch of photos of my friend Sue, a musician and singer, for her website. This was the first time I really got to use my new Sigma EF-500 flash. A lot of the photos came out fine, but some came out really dark. Here are some samples. The first two are dark, the third is too bright and the fourth looks good. http://www.sunny16.net/sue-flash.htm I shot everything at aperture priority, and the flash fired every single time. What went wrong? Thanks, Amita
