Options in Scene File

Ok, so I've been messing around with trying to get the best lighting for my camera in low lighting situations (mainly whenever i'm inside a house)

Just so you know, i'm also using a Letus35mini with a 50mm nikon prime with 1.8f stops on it, so that's why i'm trying to figure out best lighting for inside. outside i'm fine with, but inside could use some work.

anyway, i came across DRS, and noticed it's been on OFF for my scene file. so i played with it and realized when i have that up to 3, it gives me a lot more light!

now, me being the skeptical guy i am, i'm thinking, there's no way i'm getting this without some kinda sacrifice. and since i can't really find any technical information on DRS online i thought this would be the place to go.

so, what's the deal? exactly what is it doing to get me more light? is the quality going to go down for this?

Thanks!
 
It's not really giving you more light, it's bending the curves in the shadow areas. Rather than let it just go to black, it raises the dark levels in those areas.

The catch is that it also can raise the noise levels in the dark areas and there's a possible fringing effect. However, it does extend the dynamic range an extra 1.5 stops.

yea i just transferred it through final cut and after viewing it full screen i can notice the grain all over the place :/

well what would people suggest setting things to in your scene file to adapt more for lowlighting situations?
 
Slow the shutter speed as much as you dare, if you don't have a lot of movement or panning. Get rid of any extra filtration, a UV filter will cost you maybe 1/3 stop.

i've noticed in the scene file setup on the hmc40 that when i set it to any of the 'cin' settings (i guess stands for cinema) it tends to be darker. what would you suggest setting it to? which one would best be suited for low lighting situations?

i know that the best thing to do is just to light the place, and i know this camera is not the best for low lighting situations, but i do know that some settings are worse than others for shooting in low light, so i'm just trying to figure out how to configure my camera the best i can for low lighting
 
Cinema gammas are darker than the others, yes. "HIGH" is the brightest gamma. DRS can give you significant boosts in the shadows, especially on setting "3", but your image might get quite noisy. Raising the master pedestal can help see into the shadows too.
 
awesome! 'high' works the best. i'm going to try and stay away from the DRS though, that added way to much noise, i might as well be adding gain to the image
