Hi guys. Sorry I need some help here.
I've read under the section " Changing the brightness of the BG" in this article "Fill-flash use with EOS camera and Speedlite" at http://www.usa.canon.com/dlc/contro...t&articleID=106&productID=229&articleTypeID=5 that I can change the brightness of my BG without affecting the brightness of my subject by raising the ISO setting, shoot at a wider aperture or shoot at lower shutter speed.
However, when I tried shooting a scene at home (with a standing fan as my subject and dark hdb flats outside my window as my BG) using the suggested method, I was unable to attain what the article claims. When I either decreased ISO or used a smaller aperture, the subject brightness remained the same but my BG still remained the same brightness (not darker).
I used an external flash mounted on top of a 350D on AV Mode. Settings are 1/15s f/5.6 ISO 1600 for the 1st shot and 1/10s f/8 ISO 1600 for the second shot. I used evaluative metering and had my AF pt on my subject. External flash was on ETTL mode.
Any one got an idea? :dunno: Thanks!
