Shooting at -6db?

I have been shooting with this camera for some time now and always try shooting at -3db. I recently heard that the camera was capable to shoot at -6db but I do not know how to get the setting to -6db. Can someone please explain? Thank you.....

In Menu, go to Camera Set

Then go to Gain Setup

Set L, M, and H to the settings you want. In your case L -3, M -6 and H whatever else you want

Then on the bottom left side of cam you will see a switch marked L M H. These will now be set to the value you assigned them and you can choose which one you want without having to go back to Menu.

Thanks Tom! I can`t believe that I never saw that... I had the "automatic" db limits set up but never set the "manual' switches. I just figured the -6db would of been an option in "manual" also....

And if it's bright enough it's well worth shooting at -6dB Denny. Connect your NX5 to a big tv using HDMI and you'll see what I mean.

Tom,
Can you explain the -3 and -6db. in relation to how it can enhance the picture quality? Thanks...

Re: Shooting at -6db?

As I say - the best way to show the picture quality improvement is to simply HDMI your camera into a big tv. Use 0dB, then -3dB and finally -6dB, and watch the noise subside to zero as you dial down the gain. Of course going from 0 to -6dB means you've got to open the lens by a stop to compensate, but generally the difference in lens sharpness from f/4 to f/2.8 (say) is less noticeable than the silencing of the noise.

I just wondered how the camera could electrically enhance the already ultimate lens picture quality that comes from 0 db.?

When you do as I suggest you'll realise that 0dB isn't the 'ultimate lens picture quality' by any means.

Re: Shooting at -6db?

I'd check on how the camera is handling the highlights, there's often a trade off involved in using the - gain.
