Color banding using ND filters sooc
Apr 21, 2019 11:57:09 #
Over the years I have had issues with colorbanding in my images when I use ND filters. At times this banding can be seen on back of lcd screen if I look really close.
Other times I only notice it on the computer screen or I realize it is there after it shows up in print.
This problem has plagued me over the years and has kept me from selling many images.
I thought this should be a rare situation
Though it has been happening often.
I have had this issue
While shooting d810 with Zeiss lenses and heliopan Nd filters,
Now having the issue while shooting D850 with Zeiss lenses with breakthrough Nd filters.
I shoot raw uncompressed.
I use Nd filters for most of my work especially the 3 stop to give water a bit of movement. But use 3,6.10 and 15 stop filters.
Has anyone else run into this issue?
I notice this more often now that I have 5k iMac and also because I am printing more.
To clarify I always close eye price on optical view finder during long exposures,
I always shoot lossless raw.
This is tiypical color banding but will post examples if needed.

Sounds very strange. Do you have an example?

Fixing banding issues is tough but I'm going to go out on a limb and say it is impossible to create banding with a 16-bit file. So use 16-bit.

Just replying so I can follow the post, but I use Lee NDs and graduated filters on a D850 and a D800 and have never noticed any sort of artifacts.

I added a example.
This is shot in raw I have camera set to not sure why but my camera says 14 bit recording?

Raws are 14 bit (or sometimes 12). But when you open them in PS you have the option of opening as 16 bit files or 8 bit. You should always work in 16 bit, especially if you are doing any serious post processing optimization, since in 8 bit you have only 256 luminosity levels, and you can start seeing banding in gradients. But I think you are talking about something else. Color fringing? Please upload a detail of the shot, or upload it full resolution so that we can see what you are talking about.

Yes maybe it is color fringing, my computers Lightroom is set at 16 bit.
I attached an image to this thread it’s resolution is good enough hopefully for you to see the color artifacts in the water on right side.
I have many examples of this I’m other images, I also see it some of my images without ND filters now that I look closer

It is in the water on right side from the rocks to the horizon, it might be color fringing?
I have been dealing with this for years and it makes not want to shoot anymore

I attached a snap of a test print I got back fro bay photo it is easy to see in the sky.

Do you do very aggressive curve work? If you stretch a section of the curve a lot you can come up with this kind of banding, though I am surprised if you are getting that using 16 bit. If you are using PS, and opening in ACR, you have to make sure to open the raw directly in 16 bit. If it is converted to 8 bit first, it will remain effectively 8 bit even if you are working in 16 bit.
