I am thinking of doing my friend's wedding with direct flash -0.5 stop on the flash and +0.7EV on Fuji 400. That gave me outstanding results in terms of clarity, sharpness and colour saturation. But I do get hotspots... the bounce card seems to work pretty well without hotspots (at least highly muted). The effect is a lot more desirable but the shots seem underexposed. So I'm trying to find a balance that will give me what direct flash will without the hotspots..... some people's faces were very white due to direct flash..... perhaps I stood too close..... I did get some groups shots without the hotspots too..... I wonder why... maybe I was sufficiently far? I was on -0.5 flash exp when using direct flash.
The other thing is that on 1/60 shutter speed, the background was quite dark even on ISO800 film. Looks like I have to go down to 1/30. But interestingly on ISO400, the background was better but probably because I was shooting against a wall nearby so the was illuminated by the flash + direct flash as well. What u think? Any advice? 1/30 not very viable cos my hand shake is quite bad.
