Menu item for calibrating lights is not mentioned in the manual (paper or online). How does one use this? Do I need another meter, or do you compare with the meter in-camera?
I used the Chuck Garner (do a search for chuck postings) method to first calibrate my L358 to camera after I first purchased it. Once I received the CC I just compared the CC with the L358 exposure and it was spot on inside and outside..
So to answer your question I am going to say yes and no, you could just take exposures and using the Chuck method get your pure whites in PS.
Using the "white towel" method of calibration, had to dial in -1.4f on the CC to even everything up. Works more better now . Did notice how much change in white balance there is from low to high power. Will have to start using the Kelvin input for WB on camera.
On another note, am I the only one wishing for 1/3f stops on the CC instead of the 1/10? Paul, are ya listening? Could be changed with a firmware update, could it not?
At this point, I've just calibrated to match my Sekonics. At some point, I'll run a true calibration test.
And, yes, I would like a way to make larger increment jumps. The old Paul C Buff Radio Remote One control had two buttons: One for 1/10 stop nudges and another for full stop leaps.
I second the option of 1/3f stop increments. Would make it a no brainer for me since my camera is set up that way. My calibration with the "white teddy bear" method came out to -1.5 which I wondered about because it seemed so off but glad to see yours came out about the same.
Now that everyone on the forums have been screaming for 1/10f adjustments ala RX600 and others, you now want 1/3f? The anti-AB crowd would have a filed day if I only offered 1/3f increments. Granted, 1f and 1/10f buttons would make sense but there's no room in the design for that. You do know the power scrolls if you hold it up or down?
All my flashmeters display f + tenths. This does differ from how cameras display, If we displayed like camera, but used the 1/10f steps users want you would have 10 steps between stops in confusing numbers that would be even more foreign to users.
