Need some pointers from experienced Flash users.
Just got a 3rd party flash and tried it a few times. However there are a few issues with the camera with light metering and outdoor shots.
1) Usually when without flash, would adjust the settings (Shutter speed or Aperture) using the light meter in viewfinder as a guide. However, when using the external flash this cannot be done, meter could be -1 or -2 but would be properly exposed once the external flash is used.
Question : Is this normal? or is it because I am using a 3rd party flash and not an original canon flash like 430ex or 580ex ?
2) For indoor shots, for boucing off white low ceiling (without diffuser) with Auto White Balance, the shot turned out alright with skin colours properly exposed.
For outdoor shots (took a shot of Xmas trees & lightings at orchard) , when I take a photo without flash on AWB the colours were rendered correctly.
When I took use the external flash with a DIY White Matt bounce card, the person is exposed properly and colours reproduced correctly but the background lights turned very 'Yellow", a yellow tint.
If I change the White Balance to "flash" the person will turn out to be "bluish" or overexposed but the colours of the lightings will be reproduced accurately.
Question : Is it due to insufficient or inappropriate boucing of lights cos indoor shots with boucing this problem does not exist. If a proper diffuser with a yellow filter is used, will the white balance for the person and the background lights BOTH be rendered accurately ?
Sorry long post.
