Hi there guys,
I am pretty new to using flashes, just got my first external flash which is a Yong Nuo 560 II manual flash.
I have tried using the flash yesterday for a convention (Cosfest 2014) and have a few questions/problems i ran into..
First i understand that most people use manual mode when shooting with manual flash to get more consistent results, at first i was using manual and tweaked the settings to get a nice exposure, however, i realise that using manual mode means the settings i tweaked would only work for that specific focal length. For eg, if i tweak setting for 35mm and after that change to 50mm, the flash power may not be enough, or if i change to 24mm, the flash may turn up too bright. (the aperture is fixed when i change the focal length)
Is there a trick to control this? I have tried reducing flash power but i ran into a problem where i reached the lowest flash power so i resort to using exposure compensation but using this makes pictures look unnatural.
In the end i used Aperture priority mode and adjust the flash power instead, but this usually gives me pretty slow shutter speeds (the event was indoors with pretty dim lighting) which may have camera shake.
Another question is about metering,
When i was using the manual flash, i found that the default evaluative metering makes pictures look unnatural so i switched to spot metering, aim the center AF point on the face and locking focus/exposure, recompose, then take a shot.
Would like to confirm if this is the correct way to use spot metering?
Appreciate all the advise that you guys can give me, a newbie to flash photography and its been awhile that i decided to learn the other metering modes as well.
