What is causing noise

terilynne · Jun 4, 2011

Hi---I am fairly new to Photography, I am attempting to shoot in other settings on my camera--shutter priority the most--I have tried full manual and I am no where near ready for that yet---my question is--what is cause so much noise in my pictures?? I have my ISO setting on 100 most of the time and STILL get noise--I am trying to get those crystal clear pictures--HELP!!! UGHH I was going to add a photo to show you but dont see where I do that on here :/

i think you can drag and drop the photos into the text box. i dunno why you're still getting noise at ISO 100... but i think one of the reasons why noise exists is because the camera has to amplify the signal coming from the sensor. much like how crappy amps will distort and create a buzzing sound when turned too loud, the camera does that too..

Put pictures on flickr.com and then copy the link code and paste into your post. Also, it would help if we knew what type of camera you were shooting with, what type of lens, whether it was brand new or not, etc.

OK I will do the flickr thing right now---I shoot with D3000 and just have the kit lens so far--18-55 I got the camera last year

OK here is the link from Flickr--you cant see the noise until you zoom in at 100%--I was told to always zoom in at 100% to see what the picture will look like printed--is this true??

Again, what camera? Noise at 100% isn't that uncommon...depends how much though.

I listed the camera above--D3000 kit lens 18-55--there is quite a bit sometimes--just wondering if I can do something else or if other settings would help--I also havent learned anything about white balance--would this help??

I'm sorry, I didn't realize that you posted two back to back posts. I am not a Nikon shooter, but I am pretty sure that the D3000 doesn't have the greatest noise handling. Are you shooting RAW or JPEG? Your shot doesn't look that bad to me although I am not looking at 100%. The lighting doesn't look the greatest though and underexposed areas always will show more noise. If shooting RAW, try "exposing to the right" meaning shoot just slightly over-exposed using exposure comp, and then bring it down in post production. If shooting Jpeg, research the cameras noise reduction features, you may be able to tweak them a bit on camera.

Also, do not get too caught up in pixel peeping. If you are using entry level glass and entry level camera bodies, pixel peeping ( while useful in comparing different lenses and such ) can just set you up for disappointment.

Unfortunately, this "pictorial guide" has screen shots that fail to indicate one, critical bit of needed code...the URL's for the images must have .jpg added, as well as [/IMG] added after the .jpg. The screen caps in the "picitorial Guide" really help almost nobody, since they omit the critical ending of each photo's URL with .jpg[/IMG]

If a novice follows the screen caps to the letter--his or her images will NOT POST. The pictorial guide to posting is fairly useless.

The answer:
If you are shooting in shutter priority, that means the "brain" of the camera is choosing the other settings (aperture and ISO) to make up the correct exposure for the shot. ISO is what is used to gauge the light sensitivity, therefore in order to get the least amount of "noise" in your photos, learn to shoot in Manual mode, set your ISO at the lowest possible, then set your aperture and shutter speed settings accordingly and you will have little to no noise.

OK thank you! Yes I always shoot RAW--I am super new, what is exposure comp??

Nice shot.
When you blow it up to 100% this is only to judge before and after such as sharpening. In RAW you use luminance to reduce noise but this will affect the sharpness of the picture. You can't eliminate noise, there will always be some and it's a balancing act to keep a image sharp and reduce unnecessary noise. Your final image is not noisy and is not degraded by noise.
