Rate the ISO of HD111
Posted 17 December 2007 - 03:01 AM
I am about to Shoot with this JVC GY-HD111E.
I would like to know what is the ASA for this Camera at the following Condition:
Gain 0 DB
Shutter Speed 1/50
ND ilter NO
Also i would like to know stop compensation for increase in DB.
The camera specication says
Sensitivity : F8, 2000 lx
2000 lux = 185.8 FC
This gives me roughly 400 ASA at the following setting :
Light 2000 Lux
Shutter Angel 180
Is my rating is correct?
what is the exposure compensation for increase or decrease in DB?

For example, the HVX "rates," at about a 250 asa. But, often i'll have to rate my meter @160 to get what the HVX sees, and other times I'll be rated at 320. It depends on what's in the scene (with 80% zebra on white spots.)

yes ofcourse like u said it varied a lot........ i was very confused while metering and comparing........
although i checked it with close shot only....... to get a proper skin tone in various light conditions like:
Shadow in Foreground
full top light
im very confused........ it was not reacting well with exposure marks in the lens.....
finally i think i should rely only on monitor....... that is tweak the exposure ring till i get the right one.
ANY HELP ON exposure Compensation of DB (+ or -)

Sometimes, it can be too difficult or expensive to get a waveform monitor. The solution to this is the DVRack software. It gives you a bunch of monitors and scope that you can view on a computer.
If you already know this info about waveform monitors, then please ignore the post, but if not, I hope this helps

i do not hv acess to waveform monitor. I will be using a computer monitor (with a tv tuner box to convert VGA to composite or S-video). The DVRack is now shifted to Adobe premeier CS3. Although we have acess to Adobe premeier CS3, i dont't want to go that because of the short Firewire cable and also i have to use to my laptop. The LCD will most of the time give wrong colour info, particulary black and shadows.
