Advice On Removing Noise/grain

Sun Oct 26, 2008 6:28 pm

Hello! I was wondering if someone could give me some advice on removing noise/grain from an image. The noise removal program that I have is called Neat Image and then I use Photoshop Elements 5.0 for the rest of the editing. I've noticed that when I use Neat Image (This is after I've used photoshop to edit/enhance the pic) the grain/noise goes away but as does some of the quality/sharpness of the image. The filter preset setting that I'm using on Neat Image is set to "Remove only half of noise", anyone have a recommended setting to use? So really what I'm asking is how to remove the grain/noise without reducing the sharpness of the image. Thanks!

The best tip is don't produce the noise in the first place.

Neat image works well but only in very small doses if it is over used then you will get loss of image quality.

Depends on your camera. Always use the lowest ISO you can, that will help. Some cameras just produce more grain than others

I used to do that but now I do it the other way round. I first use neatimage, save it and then edit the new noise-free version. I've noticed that this helps in terms of not losing overall quality  Smile

Hi,
Just my experience : At ISO 100 or 200 Canon EOS 400D produce a grain easy to remove with Photoshop CS3 in most cases.

I never use noise removers as Neat Image, Noise Ninja, etc. because they decreases quality & details of the pictures, you can see halos...

Even at ISO 400 (cockpit, cabin, museum's shots) the noise remains acceptable for A.net standards.

I agree with EZEIZA, use Neat Image first before you do anything else, and in small doses. Neat Image tends to soften the image so if you use it first, it minimises the effects of quality. As the other have saidm try and limit the amount of noise in the first place by using the lowest ISO setting you can. Plenty of sunshinehelps as well!!!!

Buy a camera with bigger sensor.

Buy lens with bigger glass.

Use smallest ISO setting possible.
