In that case, if you already have enough, the additional light won't affect the resulting image in one way or another.

You add light - and then adjust camera's exposure to darken image... the result is the same.

If that's what it takes to get the right picture then it just forces us to become better filmakers. I want to know how to manipulate light better to get the shot I need. I am greatful that they put this feature in this "consumer" cam.

BTW, If the goal is to get as "filmic" images as possible, usually one gets *best* results (with video cameras, especially small ones like HV20) using as little light as possible - the reason for this is to get as open aperture as possible, for shallow depth of field...

Wouldn't this just add gain to the picture which increases grain? I would think you need as much light as possible but then start using ND filters to control the incoming light.

As little as possible to get correct exposure / the image you're after without using gain. In some cases, it might be truckloads, in others just a 40W light bulb.

If you add a lot of light and then use ND the result is exactly the same as using less light in the first place.

***note: when i talk about "more light" and "less light" i talk only about the intensity of the light in a technical sense, not i.e. the amount of light sources***

Thanks.it was really more rhetorical in nature...but good info anyways.

Just for the hell of it.
Have a Pre-release psd to keep interest up.

I’m going on Vacation; Stu has files, settings, and cam info....

the name of psd should give you my slant on it.

Joseph H. Moore August 14th, 2007 07:12 PM

Salah,
Those green and red circles are things of beauty. A Blackmagic Design Intensity capture station is in my future!

Joseph H. Moore August 14th, 2007 07:16 PM

btw, Salah, did you notice the BRIGHTNESS control doing anything?

I shot every different custom image setting through -1,0,+1 in both Tv and CINE mode.

Great job, Joseph.
Wait impatiently for the publishing of your results on your web site at the end of this week.
I feel now a little guilty to have push you. Hope you don't feel offended ;)

Joseph H. Moore August 15th, 2007 06:10 AM

Bruno,
It's already done. You can download it here:

http://files-upload.com/files/434996...20Life.psd.zip

You will need Photoshop, or another application that can read layered PSD files.

Bruno Donnet August 15th, 2007 08:35 AM

Link unusable (you have copied it as short text with its '...' inside instead of the corresponding long path text)

Joseph H. Moore August 15th, 2007 08:37 AM

Fixed. It's also linked on page 2, btw.

guess Stu is to busy

Joseph H. Moore August 26th, 2007 03:31 PM

Thanks for posting those, Salah. Did you happen to record to tape, as well. It would be interesting to compare of just one of the settings with the same shot after HDV compression.
