Here's more interesting info regarding various misconceptions:
Paul,
I was perusing FM at home one night, and decided to take a look at the ad link on the forum. This was an ad for some guy talking about how great his Profoto Acute B2s was. How much power control, color consistency, portable and all the other buzzwords. So I started digging into more info to compare E640/VML vs. the AcuteB 2s, (and a B/X1600/VML would not be a bad player in this either). While I do not have a formal stat. comparison made up yet (though I can, if you wish), I did find some interesting info in the Profoto manual.
http://www.profoto.com/sites/default/fi ... _EN_LR.pdf on pg 13, it states what you already know, and others refuse to believe; there is at least a 300K color shift from one power setting to another. Also, that is -300K at -4f, it does not mention what happens at -7f. Shot to shot is +/-50K, which is all they state in newer manuals. This is from Profoto’s own publication. The fact they now omit this, rather than pointing out any improvements leaves me skeptical of any actual improvement.
Just thought you would find this interesting.
