way to remove noise from picture taken by digital camera (particular those taken at low light condition)? These noise are scattered all around the picture. I tried to use the filter -> Noise --> reduce noise function, but the result is not good. There are still plenty of little grains when viewed at 1:1 scale. If I apply the neutralize, the whole picture will be blurred out.
I'm struggling with a stock agency on a few images where the rejection is for "Artifact" and "Noise". First, let me ask - are these the same? They sometimes list these problems independently. They state that "camera setting and RAW processing are the likely cause". I don't "think" my camera settings are the problem - 100 ISO, 16.7mp RAW's.
So the question is this; how do I tell if I have these issues in a file? They are inspected at 100%.
Next, if I have these issues, what is the best way to fix them? I know of the noise reduction filter, however, not sure of the best settings. Or, should I be considering 3rd party software?
When you import a video that has image noise into Photoshop cs6 is there a way of removing it? Is it done in the same way as what you would do in removing noise from a photograph?
Using Corel VS X4. I am trying to reduce or remove wind noise from video clips. These clips also have narration, which at times is inaudible due to the background wind noise! Any way to remove or reduce this background noise?
Using Gimp 2.8 in Windows 7. I have a scanned image of a topological map. At areas where the contour lines get too close, squares appear in between the image (See attached photo). Is there a good way to remove these extra squares in the contour lines rather than tracing the lines manually?
1.   When to apply noise reduction is very positive and unequivocal.
2.   There are no two ways about it.
3.   You better get it correct.
4.   You don't want your images to look like Phil's images. Read the following very carefully  PS: Is the DxO RAW converter still considered to be the best noise removal software on the market. How well will it do on my old JPEGs.
I have rather large blueprint that is black and white. Their is some noise around some of the black lines / text / etc on the drawing that I want to get rid of as well as get rid of the white back round all together (which I am hoping will reduce the file size a bit). Â How to best remove the white backround / remove the noise from this large drawing?
I have pictures that have different objects over a canvas like/un uniform back ground.
I need to remove that background without any part of the objects them self.
I mange to get most of the background out using the magic wand , but i'm left with many random single/groups of noise pixels left in the picture since they were not captured with the magic wand.
most of the time i can remove those using the eraser or use the selection tools with different shapes around the pixels and press delete.
but those methods take lots of time, specially around a complex objects and as i'm getting near to them, i need to make my selections/eraser radius smaller and smaller.
I have tried to use a plugin called "Reduce Noise" that i found , but it does not work.
faster way how to remove this noise pixels without any part of the objects?
a plugin that "scans" the image/selected area and remove all pixels that are surrounded by transparency in it?
p.s I can't always select only the object/s itself/them self and just move it/them to a new picture.
p.s.2 maybe a plugin that the user can choose up to what size, a group of pixels, should be removed ?
Opening a Canon .CR2 in Photoshop CS6, Camera Raw generates a significant amount of noise or graininess in the image compared with the simultaneously saved .JPG file. This results in the image from the raw file being of reduced quality. I never had this problem using Photoshop CS5.  Is this the result of some setting being turned on? If so, I have been unable to figure out which one. The only other possibility is that there is a severe flaw in the latest version of the Camera Raw plugin.
What is causing the colored noise in the above image? This appears before I do any editing. When I import the image from Lightroom 5.Â
I turn on the Gamut Warning, and it disappears. I know. But then, obviously, the gray from the Gamut Warning occupies parts of the image. I open the image as a 16 bit PSD.
I am trying to create a star field for this school project. I've been trying to create one using the Add noise feature on a black background. I get to the point were I'm pretty satisfied with the end result. I used some other adjustments like curves, brightness and contrast, and exposure. All of these created a pretty solid star field. However I've noticed two things when trying to save the image at hand as a JPG or apply the image to a new layer. Both instances yield the image reverting back to the initial add noise, as if it adds the original noise I started with when I first began the project and I'm at my wits ends as to why it's doing that.
I hope this is the right place to ask. I have had some people complain that there is often noise in many my photos. The problem is I am unable to see it myself. Maybe it is my poor vision. Mt question is, "Is there a way that a person can make the area of a phot that has noise in it stand out like in a highlite or something making it obvious where it needs removed?"
I am envisioning a software that makes all areas of the photo red where the noise is. I have the software tools that you use to remove it but first I need to be able to see it. If this is the wrong forum for this question, please direct me to where the right one is. Notice, I did not say, "Tell me where I can go?.
I can't remember reading any tutorials on dealing with noise in Photoshop. Scott Kelby dedicates a whole paragraph in his CS3 book for digital photographers. I need to make a decision on what noise reduction plugin to buy, so if you can reply to thread I can get a consensus of what is being used most.
I recently began creating an image and when it came time to flatten this image, the noise I intentionally put in was softened to a regular glow. I am using CS2 and i used the Layer Style > Outer Glow > and then I added noise with blend mode linear dodge and an opacity of 68%. Anyone know if there is a way I can flatten the image with a way to maintain the noise?
If the circumstances force me to work on images with noise which have to be enlarged, and if I use noise reduction based on noise-pattern-recognition, is it better to carry out the noise reduction before or after the enlargement (and in case the answer is after, which resampling method would resample the image (and thus the noise) best for subsequent noise reduction?)
I do a lot of UI design and webdesign in Photoshop and as most people I like to apply a subtle noise here and there. I usually do it this way:
First I decide whether I want black or white noise. Secondly I create a new layer and fill it with opposite color. Then I choose Add Noise and apply 100% uniform monochromatic noise. In the end I choose between Multiply and Screen mode according to the noise I want and play around with opacity. Â Now I am coding a website in HTML5 and CSS3, which allows me to recreate all elements without unnecessary images and workarounds, but I am not able to create appropriate texture to emulate the noise. For example black noise: I wanted to create the noise as I usually would, just skipping the Multiply blending mode part and rather trying to substitute white color with transparent (and accordingly for shades), meaning I will get document where some pixels would be 100% black, some would be 0% black, and the rest between. In CSS I would then repeat this over some element and change opacity accordingly.
Noise Ninja crashes my PS CS6. What'e even worse is PS CS6 can NOT be restarted without restarting the computer first! As the noise filter in PS CS6 works really poorly, any software that works? I use the 64 bit version. No other problems - so far.
Level: Newbie  OS: Windows 7 64bit   Ps: CS6  I went through a half A***d tutorial (to make an iPad) which was a huge part of my problem ...  The tut would say to do things that couldn't be done - so I would find an other way ... which I believe created problems  when I was done making the iPad and then tried to Group my layers into some sort of order ...  The Noise (Filter) I used on the Main Shape of the iPad spilled out of its Clipping Mask and onto the BG layer ...  or actually onto every aspect of iPad  Am I assuming correctly that having moved the Layers around and placing them into Groups somehow disrupted the Clipping Mask?  I read that I can make a New Group and then just drag the Layers up to the Folder  However, I couldn't find in the manual anything about what to do when moving Layers into New Groups goes wrong ...
