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***

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.

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?

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 ;)

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

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.

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.
