Paint.NET :: Noise Reduction On B&W TIF Images - Bad Speckling
Dec 12, 2012
I use paint.net all day long in my career - I have the task of editing age old technical drawings that have been scanned. Some go back 50+ years.
I'm looking for a plug-in on steroids similar to the "Reduce Noise" that is already contained within Paint.net. Some of our drawings are QUITE speckled and the existing command doesn't "despeckle" enough.
I've looked on the forum and came across "GREYCstoration Wrapper" , which was supposed to have been replaced by the "Reduce Noise" plug-in. Both of those return an error page when I try to view the post.
I do a lot of timelpase photography and use Adobe software in my post workflow. I would like to master the process of using black images to reduce the digital noise of astral timelapses taken at 3200iso. I work in a RAW workflow then output to DPX image sequesnce.
I started on a timelapse forum with a similar query. I am just wondering if there is a way to do this with Ae in the RAW workflow or something similar. Instead of using other software. Maybe a Ps batch process? URL...
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.
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?)
Working on a night shot of a building and processed through ACR7.2 and forgot to reduce the noise - and opened in Photoshop. Went to Filter/Reduce Noise and immediately get wierd banding in the window blinds. This banding is there regardless of the noise reduction settings and could not get it to go away - See attached screen shot of before and after applying the filter. So I went back and opened the file again in ACR7.2 and applied the Noise Reduction there and bingo, noise level dropped and looked good with no banding. Looks like the Noise Reduction capabilities in ACR7.2 are way better than the Noise Reduction filter - but surely the banding should not be there; especially if images do not get processed through Camera RAW.
Running latest version of Photoshop CS6 (latest patches applied), Windows 7 x64 16GB RAM, Intel 4000 with latest drivers installed. Camera file was ACR2 from Canon 5DMKII imported as a DNG file - then opened in ACR 7.2
Before Image Opened in Photoshop before applying the Noise Reduction Filter. After Image in Photoshop after applying the Noise Reduction Filter. Seems like a bug to me .By the way, the screen captures are from the image viewed at 100%.
I've just exported some pictures for the web from Lightroom 5 which had to be downsized considerably. I now find that the sharpening and noise reduction palette has disappeared entirely from the right hand tools panel. What's going on? I've tried quitting and re-opening Lightroom and also shutting down and restarting my computer. (Macbook Pro retina and Mountain Lion)
I want to use the "Add Noise" effect but have it apply to a transparent layer. In other paint programs, this would just add generated noise pixels to the currently selected layer, but in Paint.NET it appears like it's using the source pixels as input for the noise effect. While visually this effect is pretty on existing image, it doesn't work on transparent layers. Is there a way to just add regular noise to my transparent layer? What I'm just trying to achieve is generate a television static effect, but have those pixels that were left untouched by the noise effect remain transparent. I need the transparency for use outside of Paint.NET. Is there a way to do this?
I actually do like using the software and I do like the updates and where it is heading.
I ran into a small problem last night when using the Digital Noise Removal plugin. I was playing with settings and unlinked the Noise Correction sliders and moved them about. Then I tried linking them back and clicked on the Large slider to make further adjustments when a blank alert dialog popped up. I can click the blank button and it disappears and seems to continue work, although the settings barely move. Each time I adjust the Large slider after this I get the same dialog.
What is a VERY good noise filter plugin for X4 or X5? In the past few months I demo's Adobe's Lightroom which had an excellent noise removal capability.. AMAZING really. The problem with Lightroom was NO support for PNG files.. and I have 10's of thousands of them. Many of my images need such a noise filter, and the stock one isn't so hot.
A question for the PSPx5 experts. Under Adjust/Digital Noise Removal there is a check box for 'Camera Preset'. I like to use this and have set up a preset for my Nikon D7000. The problem is that if I'm not quick to click the check box, PSPx5 starts to run the noise removal. (It seems as though once started there is no going back. If I start again I get an 'over processed' image). Is there a way of opening Digital Noise Removal with the 'Camera Preset' as the default? Or is the 'Last Used' option using the 'Camera Preset' that I last used? Ideally I would like the 'Camera Preset' box checked all the time.
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).
How to best remove the white backround / remove the noise from this large drawing?
I use Nikon cameras and shoot raw files processing them in ACR and then bringing them into Photoshop. I notice that after the images are processed and saved as jpegs. when I look at the final image in a Microsoft film strip browser, the noise which shows in Photoshop disappears in that viewer. In Photoshop I am viewing everything at 100% I cannot figure out how that happens and what is the true quality of the image. I am just wondering where I can see the true final quality of the image. I would rather not use any noise reduction on the images. I do not like the quality of the image after using that tool.
I’ve been looking for over 2 hours now how to do this and I’m still no better off, however I have learnt a few tips here and there,so I’m totally new to gfx stuff but i know how to make an image transparent.
i want the logo on the image but i dont understand how too?? ( with out getting all the grey and white boxes (around the logo on the greenhouse pic which goes white once i save it) i want the image background to still be there.
