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 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.
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 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I've looked on the forum and came across "GREYCstoration Wrapper" , which was supposed to have been replaced by the "Reduce Noise" plug-in.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...
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.
I would like to know to reduce a photograph to a simple drawing using a minimal number of colors such as 3 or 4, or even black and white. Here are a couple of samples of what I would like to be able to do. Is there a PS filter or technique that will do this type of thing?
To me, this sounds completely backwards, but for some reason I cannot figure out how to do this the right way. Every time I use Image Size to reduce my high res image proportions, my resolution goes to shxx. By luck, I managed to find the right way to do it last week, and I cannot get it to work today.
Wanted to use this new, cool tool, but got the error message "No more virtual tiles can be allocated". ???
This is not a scratch disk error, as I have two-2TB drives as my scratch disks (nothing on either yet). 16GB memory (RAM), 14680MB available memory to PS, 2030 available VRAM. Running nVida GeForce GTX 670 on a Intel Core i7-3770 CPU @ 3.40GHz.
Is this a GPU function that may not be available to some graphic cards? Is my image too big (4000x3000px)?
I am a new member and a fairly new user of Photoshop. The company wehre I work had outsourced icons in 16 px x 16 px size bitmaps with magenta background. They got the results they were looking for. Please see blown up image below:
Notice that the image has a uniform background color that we require!!
I created a similar image of 160 px x 160 px size in Photoshop. When I reduce the image to the icon size of 16 px x 16 px and save as a bitmap file, the background is pixalated.
