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 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?)
Noise reduction in Photoshop Touch does not work. Move slider and nothing happens. I also have Photoshop Express, and noise reduction works fine with it.
I have a question about applying noise reduction. Where in the pipeline should noise reduction take place? Should it happen before color correction or should it be applied after?
And what should drive such a decision on a per shot basis?
I figured you do not do this pre-comp, due to the fact that noise reduction has the effect of removing detail quite often and may effect edges.
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'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 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...
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.
If you see the face iv used a smooth brush and its bringing out all these noise spots. If i try to darken a background its totally unusable. Iv never had these presets and brushes do this but the last 2 sessions iv had massive issues, Its happening on pics which i wouldnt think would have issues and have never had issues before. Lightroom 4 had none of these problems.
After playing with a new install of CS3, I see that there is banding in high value pixels. Yet when I open the same file in CS2, the photo is fine. I use a CRT. On my laptop, both versions work fine.
If I make a 16 bit untagged file with a black/white gradient, there are unacceptable bands throughout.
I've tried all of the options from the Color Management Policies: Preserve Embedded profiles; Convert to working RGB; and OFF. My working space is Adobe RGB.
Every time I try to use shake reduction, it works on the photo but then immediately crashes Photoshop CC and I have to reboot the computer to get it to open again. I suspect it has something to do with RAM. Mine is set for 1192MB. Is that enough? The images I tried were about 2000 x 3000 at 72ppi.
