Thanks !! :)

Thank you so Much for the feedback..

Thank you so much for the reply...I increased the brightness to 15 in post.
Wouldn't it add more noise in the scene if i increase ISO to 800?
So the only way to avoid noise is to shoot the scene in the bright or daylight and bring down the brightness in the post?

Thank You So Much for the Guidance...I have noted down all the points you mentioned here..I am creating a scene where a character is sitting alone in the room. He is worried and the scene is dark. I have recorded the scene with these settings;

f-stop 3.5, Shutter Speed 1/30, ISO 200 and i am getting this in the output..

This image is so noisy. Kindly tell me some way to reduce noise in this type of scene. Is it possible to reduce noise by changing camera settings? or i have to use some more lights.

Thank You So Much for the Guidance.. I will try out these things and post the results..Right now i am getting this result.. http://postimg.org/image/lv1mld7rd/ at f-stop 3.5, Shutter Speed 1/30, ISO 200.

Thank You so Much for the Guidance :)
