holy badass! was that shot in color or some sort of color filtering in place?
Thanks. It was shot in color, then converted to B&W with blue filter using Nik Silver Efex Pro.

yeah, I love how my D90 can handle high ISO very well... pretty much a budget D300
the D60 I had totally blows at ISO 800
let me guess... they played 21 guns? I effin hate that song! its overplayed and all the say is "one, twenty one gunssss" SO ANNOYING haha
it's not just grain in sleeper3's pics, it's noise.... its pretty disgusting
my D90 won't do that in that kind of lighting at 1600
I wasn't really talking about your pics... they came out pretty good considering the circumstances
a full frame camera is practically immune to noise
oly 14 miutes... Wow, my head exploded..
coolAn image sensor is typically comprised of a matrix of light sensors. A light sensor can be thought of as simply a device that converts light into an electric charge. Each square of the image sensor matrix is a photosite, usually with one light sensor 'painted' on it. A photosite generally corresponds to one pixel in your digital image.When light (photons) strike the image sensor, electrons are produced. These "photoelectrons" give rise to analog signals which are then converted into digital pixels by an Analog to Digital (A/D) Converter.
There are a number of sources of noise contamination. Heat generated from electronics inside the camera free electrons from the image sensor itself, thus contaminating the "true" photoelectrons. These "thermal electrons" give rise to a form of noise called thermal noise or dark current. Another type of noise is more akin to the 'grain' obtained by using a high ISO film. When we use a higher ISO, we are amplifying the signal we receive from the light photons. Unfortunately, as we amplify the signal, we also amplify the background electrical noise that is present in any electrical system. In low light, there is not enough light for a proper exposure and the longer we allow the image sensor to collect the weak signal, the more background electrical noise it also collects. In this case the background electrical noise may be higher than the signal.
So why is using a larger image sensor better? Each photosite itself generates electrical noise that can contaminate its neighbor. In a larger image sensor, the photosites can be physically further apart and thus be less affected by that contamination. A larger image sensor also means that the photosite can be larger, thus have a larger light gathering capacity. It is therefore able to generate a larger signal to noise ratio. That is why a digital camera with 6 million pixels crammed into a 1/1.8 in. image sensor has more noise (especially at high ISOs) than a 6MP digital camera using the much larger half-frame (APS-sized) image sensor.
So as you can see, having a larger sensor will help reduce noise but will not eliminate it. The noise generated by a full frame sensor at ISO 1600 will be less than a crop sensor at the same ISO. But it all depends on the manufacturer and the quality of the sensor. Cranking up the ISO on any camera is going to increase the noise, larger sensors just handle it better.
