I've shot some tests on the D21 with HMIs and the results were very good. However, this week I'll be shooting under tungsten and would like the widest latitude. (The level of illumination is not a problem as we'll be in a large studio.)

With other video sensors I've found I get better results by colour correcting with a filter rather than electronic white balancing. It is probably because of individual colour channels clipping when uncorrected.

Any thoughts? Also, I haven't been able to find an exact colour temperature rating of the D21's sensor.

Sid.

Hi Sid,

in terms of sensitivity there isn't much difference between 3200K and 5600K on the D-21. 1/3rd stop max and more noise in the blue channel, due to WBal set to 3200K. A tungsten to daylight filter will costs you about 2 stops. If you'll have enough light to compensate, you may get slightly better results with filtering.

Best regards,
Olli
