I'm pretty familiar with depth of field, but the entire image was looking like detail was being applied. When I returned to the pp menu, detail was in fact on, even though i specifically remember turning it off.

The noise does seem to have gone away when I used the halogen, it's like if the overall image is darker then a crapload of noise shows up in the shadows

The attached picture is straight from an EX1 sitting on my desk, 1080/24p shutter off 0db gain, f/1.9. The picture profile is Bills TC2, detail off, with blacks at -2. Do you see all that noise in the shadows, specifically the wall? Should that be there?

Also completely unrelated, I've been having trouble in general getting that ridiculously good looking look out of the camera that people seem to effortlessly get. (Yes, including grading) It's like I have something in the picture profile set horribly wrong.

Aside from all the other things people have noted, you'll always get noise in shadows. The lowest range from a sensor is really about at what level is noise unacceptable in the shadows. As is noted too, blue sensitivity is a fundamental characteristic of silicon sensors. So low tungsten light and shadows are the worst combination for this. It's also not just the EX1, everything to a degree is similar. The nice thing about the EX1 is that it is a 3 sensor camera so analogue gain can be just applied to the blue sensor without affecting the others - difficult in a single sensor design.

Download the original file if you like. I'd be curious to see what you think of it in comparison to your scene.

That looks excellent Perrone, were you shooting at 0db? I think my original noisey image was due to balancing to yellowish light, detail being on, and perhaps a couple other things. I'm getting better results now that I changed a couple things.

Perrone,
What was the color temp for the bulb you chose?
