Paul-
Your statement that I quoted said \"requires firmware modification to run from BatPac. \"
That statement is incorrect. The D1 can run sans-firmware upgrade, but it will deplete the battery faster than it would with the upgrade. The D1\'s I used in my recent blog posting did NOT have the firmware upgrade. Therefore, they do NOT REQUIRE a firmware upgrade to operate on the Batpac. If you do want to run 4 D1\'s at a time and increase battery life, then YES, the firmware upgrade is suggested. In my personal usage I popped off 125 full power flashes and 200+ shots at mid to low power on the same charge.
For someone like that is so focused on minutia I fail to understand how my previous response was ambiguous.
As far as pointing you to a technical sheet on the D1- Google is very useful in finding such information:
http://www.profoto.com/sites/default/files/Users_Guide_D1_EN.pdf
Page 20- this statement applies to ALL D1 monolights
Color Temperature, K- 5600
Color temperature consistency, K +/- 30
It would be responsible to do your homework before you claim something can or cannot do something. To borrow your words, \"I believe you (are) accusing the wrong party of spreading mis-information.\"
Well, I guess I have to take back everything good I said about you in \"your\" BatPac\" Profoto commercial thread..
First, if you look there, you\'ll see I already posted the link you mention, and yes I read it start to finish.
I\'ll start by making a challenge (I would make it a $10,000 wager, but don\'t think bets are appropriate here. Any legitimate photographer who owns a D1 and a decent color chart please take a RAW test shot of the color chart at Full Power, and another one at minimum power. If the color temperature difference from Max to Min Power is not closer to 500°K than 30°K I\'ll eat my shirt, buy you dinner or whatever you want.
As to page 20, it states the \"Color Temperature Consistency\" as +/- 30° and in a separate spec states the color temperature as 5600°. This is pure and simple deceptive specsmanship and you fell for it hook line and sinker.
If you know how to decipher this, it says the shot to shot color consistency at a given power setting is+/-30° and, in a separate specification, it says the base (full power color temperature is 5600°.
Nowhere does it define Color Temperature VS Power Setting. Maybe you don\'t know why this spec was omitted, but I sure do . . . because there is at least a 400°K shift . . . probably a bit more.
As to the firmware thing, I direct you to your own \"review\" at http://blog.profoto-usa.com/?p=2064 specifically “Batmode” – Why you need this Firmware Update for your D1′s\" You yourself said You need this firmware.
Profotos site itself doesn\'t even work . . . . http://www.profoto.com/batpac/product/tech-specs . . . brings up \"Error - the info you were looking for was not found or is inactive\"
I\'ve spent entirely too much of my time trying to find actual BatPac specs to no avail. At one point a ran across a discussion of how many D1s of what power levels can be operated from this thing, and which combinations require the firmware update. Too bad Profoto can\'t actually put up the complete specs, free of misleading implications. Maybe they only do that for Swedes . . hell I don\'t know.
As to your \"If you do want to run 4 D1\'s at a time and increase battery life, then YES, the firmware upgrade is suggested\" I believe this is in error. To run four D1s, the firmware is required, not suggested.
In the meantime, I sincerely hope that someone who has the whole spec sheet for this thing. And I sincerely hope that someone with a D1 and no bias will verify the color vs power constancy issue before they start tearing into me for trying to correct false and misleading information. Hey DC . . . you\'re the one that owns a D1 . . . why not take few minutes to do this yourself and prove or disprove what you think to be true. I would do it for you, but I\'m not going to go out and buy a D1 to prove a point
At this point, I standby \"I believe the wrong party is being accused of presenting incorrect info\"
This whole thing is looking more and more like Model Mayhem, where hardly anybody actually knows what they are talking about.
