Tutorial for processing One-shot color images?

[mcbbcn]

Hi,

Does anybody has a good example or tutorial on how to process one-shot color images?  I've seen the LRGB one and I've learned quite a lot from it, but I was wondering how does the one-shot images differ in PI processing techniques.

Also, I would be interested in any one-shot color processing with light pollution.

Thank you,

i don't think the processing is substantially different outside of the LRGB combine... one can however generate a synthetic L image from the RGB and do a similar workflow. i rarely do this, though.

Hi pfile,

I use a Hutech LPS filter which makes my colors look a bit off.  Do you or anybody has any experience normalizing the colors when using LPS filters?

Thanks for your help,

M.

oh sorry i missed this question.

i am using an astronomik CLS filter and yes, there is usually a blue cast. however, just asking the STF tool to autostretch with channels uncoupled generally gives me something reasonable. then i use BackgroundNeutralization ColorCalibration to get me the rest of the way.

i find that the real problem is that my red channel is underexposed compared to blue and green. with my canon 50D, this can lead to banding in the red channel.

As a starting point, the DSLR tutorial is an OSC workflow. The Batch Processing script does the same.

The warning about final image quality when using the BP script can be ignored for a trial run.

ABE and ColourCalibration should remove CLS gradients effectively.

Hope this helps?
