prosumer camera question- for brian mostly

[P4RK3R]

I was wondering out of curiosity if you can set the ISO of prosumer or consumer level video cameras?
my sekonic l-358 light meter can tell you what aperture you need to set your video camera to to be able to shoot a certain FPS, but you have to dial in the ISO when using that feature...

or do they make different tapes, like ISO 100 and ISO 400?

thanks

Im pretty sure theres no way to adjust ISO for video cameras, i don't even know if ISO applies to video (maybe film, i have no experience there though) All DV tapes are all the same other than lube and the tape quality.

ISO is similar to gain, i guess?

 

[Brian Boston]

I think they have similar functions, but gain on cameras (on dvx atleast) is measured in decibels, and i think the default is 6dB

oh, that makes more sense now, that adjusts the sensetivity.

ok thanks. you can lock/ delete this thread if you want to.

and james, i dont care. your posts mean nothing to me.

Sorry to bump

Iso is not gain

Incresed iso means increased sensitivity means more light captured per unit time

Gain is an electronic amplification of the picture.

Also you can adjust iso if you shoot film, im looking into getting an old 8mm. YUMYUM!

They kinda do the same thing though don't they? Like the higher you go the brighter the picture, but the more grainy it looks?

Enabling the camcorder gain control brightens an underlit picture by amplifying it electronically (it's like turning up the volume on your stereo). The result is a trade-off in quality because picture noise (snow, graininess, poor color) is amplified right along with the picture. Even so, the gain control will sometimes produce an image that you otherwise couldn't record.

so would a lot less gain, like ISO 100, look noisier than, say, ISO 400?
sorry if im confusing you
and thanks reeves
