Seeking advice: M-P 3200 ISO files, managing noise.

Trying to learn how to (best) manage noise with shots in dark conditions. Your feedback would be appreciated. (Uploaded to my Google Drive original DNG and various JPGs at different stages of LR editing--file names captures what I did. Please access at your convenience.) 

 

Are the patterns that run horizontally what are commonly referred to as "banding"? 

 

Is this the best one can do with the image without further smearing details?

 

Thx in advance.

A plugin for Photoshop called Noiseware (http://www.imagenomic.com/nw.aspx) works very well and cost about $80. I have tried a few plugins and I find this one to be the best. With Noiseware you can create a second layer and you can mask out areas where the noise reduction has removed too much detail. Here is a video to show you how to use it.

Hi MMX_2, just to say that I am a real user for Noiseware and no I do not work/have anything to do with Imagenomic. I have tried Topaz and found it very slow on my system I also was not too impressed with the output. Nik software was good but it smeared the detail a bit more that I liked. Give Noiseware a try. However, if Topaz works for you then that is great. I love choice!

 

Noiseware is about $80 I think, so it is not the cheapest.

That is an inspired idea. Really. So when should we expect your cheque?  :p

 

Point taken.  To me, it boils down to time, money, and results.  If the OP's primarily taking photos in these conditions and is having to spend a lot of time removing noise from individual photos then switching platforms is worth considering.  It will cost some money up front but it will save a lot of time and produce superior results.  If OP's only taking the occasional photo in these conditions then the cost of switching cameras probably isn't worth it.

Thanks a lot for the tip!! I will check Noiseware instead :)

Switch to a 246, SL, or Q.

 

The 240 is not good at 3200 and up.

 

Sure it is, if you use proper photographic technique which may include consideration of light, exposure and possibly adjusting the contrast when processing the image.

 

This is nothing new, photographers have been working like this for decades, I sure have.

To me all these products do a good job, however ACR and Photoshop are quite adequate.

 

+1.  Yes, they do.

 

After reading this thread I did a casual comparison between Nik Dfine 2, Neat Image, and Noiseware and found all do similarly good jobs.  That said, Nik Dfine 2 has a setting for removing banding and the other two don't, and so they weren't as good at removing it.

I have slowly started "accepting" M240's ISO 3200 files. Earlier I tried to remove noise in LR but now I simply leave the noise/sharpening sliders all the way to left at 0. Now I like the small grain of ISO 3200.

 

If the photograph is properly exposed then any attempt to reduce the noise affects rest of the picture negatively. Of course if you have underexposed then lifting shadows will bring out more noise. still, noise doesn't bother me as much as banding does. My solution for banding is to crush the shadows so that it is not visible in the print.

 

Note that you see lot more noise/banding on a monitor than in the print (which has less dynamic range). IMHO attempts to reduce noise should be made with consideration to final output.

 

My 2 cents.

NIK's "de-banding" option is what makes the plug-in worth it.  If looking for general noise reduction, NIK does okay, but nothing special in my opinion.  The M9 had banding at high ISO, the M-240 does - even my A7II does.  I get alot of value out of the debanding feature.

 

I've used the de-banding even on base ISO shots that have been edited (ie - boosted shadows, levels edits, curves, saturation, etc) and it's interesting to see what it cleaned up on a supposedly "clean" image.  I didn't notice the banding in the edited image, but after running the debanding and comparing the results, there was a definite improvement.  Why do this (on a base ISO image)?  If it's a small cropped image, say 10 MP, and has undergone moderate editing and planning to print on 24" printer, those "bands" become noticeable.  So cleaning them up (even on a base ISO file) can help with the print quality (when extrapolating upwards).
