What are the best ways to reduce Camera Noise?

[Grungble]

I want to take photos like the one below and help to reduce noise while shooting, I don't really think I'm capable of reducing noise outside of using the camera's software and hardware (and yes I do have all nose reduction on, quality all the way up, and shoot in raw), I'm looking more on the side of different techniques of shooting, rather than buying something to fix a problem.

Whats your camera setup?

 

THis image really doesn't look to bad at first glance to me

 

Nornally noise comes from higher iso's and this image is shot at iso 3200, and 1/1500 shutter speed. Since there isn't any motion in this shot, id probably shot at something like iso 400 and 1/160 for shutter speed. That should reduce the high iso noise a lot, and the high shutter speed isn't needed here.

For this photo I used a Pentax ist-DL and a pentax 15-55 mm lens

Yea id try a lower iso and lower shutter speed, should reduce a lot of the noise, and older cameras like that one don't handle high iso's as well.

ok thanks for letting me know I'll look on how to lower the iso on the camera because I'm familiar with changing shutter speeds.

Assuming you keep the aperture the same:

 

Let's say you take a photo at 1/1000th of a second at 2000 ISO.

 

If you increase the exposure time to 1/500th of a second you can halve the ISO to 1000 and get the same overall exposure. If you drop the speed to 1/250th you can halve the ISO again to 500. 1/125th of a second -> 250 ISO. 1/64th of a second -> 125 ISO.

 

Of course, at some point you'll have a shutter speed that is too slow to freeze motion and get a sharp picture.

My camera is very old and dumb sooooooo, the iso only has the option for 200 400 800 1600 and 3200 and it is a pentax *ist-DL

The same principle applies

 

Double the time that the shutter is open for, halve the ISO to get the same exposure levels.

ok, thanks for letting me know
