Oh man I have heard so many different things concerning flash and im starting to confuse myself. I dont really know where to start so Ill just rant on about a few things and hopefully someone can clear things up for me. I normally use aperture priority for everything else and for flash this doesn't seem like the best idea. In low light the camera wants to use a slow shutter to properly expose the ambient light, while I want a fast shutter *AND* shallow depth of field using a large aperture. I tried to use Tv in this situation using 1/200 and it produced the lowest possible aperture (for this slow lens) of f/4 (blinking) but still produced decent results because the flash properly exposed the subject. I was also trying to use the lowest possible ISO. Any better ways of doing this? I don't want to spark up any debates here, but some people use the flash in manual. If you adjust the flash output, how do you properly expose in situations with variable ambient lighting on the subject itself possible producing over exposed subject. Is it normal to not be able to properly expose the full scene and only the subject (so you always get a blinky aperture/shutter speed in your viewfinder)? I am shooting ON-CAMERA bouncing the flash off ceiling or walls etc... Also, i read somewhere not to use high-speed sync in low-light? Can someone elaborate? One last question, if I am outside and trying to reduce harsh shadows by using the flash as fill-light, how would I go about doing that?
