jnanian (and all): 'Obscene' was too strong a word. I really meant that if you are just starting out trying this lack of meter, then it could be very wasteful indeed.
But, jnanian, don't fall into the trap of relying upon the 'forgiving' aspect of negative materials (ie, E-6 is NOT so forgiving). Always relying upon such will reduce your need to know and that is what this thread is all about: learning how to hone your efforts into, or close to, perfection.
'Latitude' is not an attitude to adopt, Instead, it should be the ambulance that gets you to the emergency room on time. - David Lyga
