"If you're going to check and adjust the output with the TTL flash
compensation, why not use
manual"
Making generalisations is dangerous but usually you can get close enough
*without* having to
readjust compensation and then TTL may be a time saving convenience:
Remember, often I am just filling in the ambient with a stop or two below
required exposure, so I
dial in a modest negative compensation to give a little more over-exposure
margin, knowing the
ambient fill is not going to contribute a lot to main subject's exposure, which
is what needs to
be adjusted by "ttl". It helps that the ambient fill might typically be a room
bounce,or similar
large diffused flash, so does not have inverse square law falloff like the on
camera (TTL or auto)
direct flash.
