Pro HD LoLux : gain up to 30 - 36 and 42 db !

I think this firmware update is for hd 200 serie.

http://www.studiodaily.com/main/news/8205.html

Does anyone tried to shoot by night with those new gain levels ?

We've had discussions about this firmware upgrade in this forum before. So far, nothing has appeared on the JVC website, and calls to tech support at JVC hasn't shed much light, so to speak, on the subject. Most of them are as in the dark as we are.

I can't find anything except that one article. Is there any new info on this?

I never use more than 9db gain anyway. Is LoLux even worth using for professional videography?

I've recently done a series of shoots at *ahem* adult entertainment clubs for a client. Obviously there's a serious lack of lighting in such establishments. I used the HD200 (17X lens) in DV mode, with gains varying from 3 to 15. Gains in 3 to 9 had acceptable levels of grainyness (is this a word?) for the shoot. Even 15 made a nice effect in one bar.
What I find desirable from the LoLux is the increased light sensitivity with lower levels of noise. I could have really used that in this shoot and with upcoming projects. Anything that makes an image better in lower light levels is a great improvement, in my opinion. However, I still haven't heard anymore on this from the JVC website or any other source.

Perhaps with a tripod, by night and without moving... to shoot sleepy towns. Or perhaps especialy with moving things for strange effects... if the quality is there.

As I said earlier in the other post. I talked to the technician at JVC who's involved in new firware updates. He said it was a test some time ago, but not good enough to release at that moment.

It was implemented for ENG shooters like Scripps TV that bought 150 HD250s. It's not for EFG shooters.

I didn't mean NOT for us -- I mean't not of much value for us.

I assume it will be available for everyone.

So why don't they hurry up and give it to us already? Why is JVC refusing to acknowledge this upgrade?

"Called LoLux, the software gives the user 30, 36 and 42 db of gain, specs offered on more expensive cameras, in addition to the gain settings that ship with the camera’s standard software. LoLux is comprised of half electrical gain and half light accumulation through the shutter."


"JVC has developed new firmware for its ProHD cameras."

It actually doesn't say the current models are "upgradeable" -- only that "new firmware" has been developed.

Perhaps no assumptions should be made until we read something from JVC. It will only be for 200-series or perhaps 250 -- not 110.

Why? Is the image processing between the 100 & 200 that different?

As I remember, 14-bit DSP vs 12-bit DSP?

There seem to be a lot of guys interested in this LoLUX, which I bet is aimed at News applications. Or for the people that shoot "Cops" type programming.

I agree with Mr. Mullen. Dollars for donuts this is for 200/250 series and I bet it will cost extra.
