HVX noise

[stephen lamb]

Hey,

 

 

I'm prepping for a short film on the HVX and I was running some gel color tests the other day. My goal for the test was just to compare some different gels at different exposure levels to see how they reacted. Test shot with a PS tecknik and Zeiss SS 25mm. Shot at default 3.2K and tungsten lamp. A side benefit of this was that I wound up with a wide array of low, proper, and overexposed shots to test noise issues with. I took one shot, which was exposed normal, and "printed" it down in color correction to roughly match the waveform of the underexposed shot. The correction involved bringing down the mids, a small amount of bringing down the highlights, and then removing some of the saturation. The difference in noise is quite amazing. I've attached some slightly scaled down .jpgs screen grabs.

 

This is the properly exposed shot "printed" down.

 

This is the under exposed shot.

 

 

I guess it goes to show that for this camera if you need a low light shot, to do your best to get a solid exposure and then bring it down to where you need.

 

PS sorry about the bad pixel aspect ratio.
