Processing Sequence

[John_Gill]

Hi,

Is there a preferred sequence to processing an image?

I am still learning, but I had the same questions when starting and still come across steps I am unsure about.  Others can chime in.  Every image is different and will present it's own set of steps required.

I try to break down the sequence to Linear and Non Linear.  After proper calibration and integration your image is linear and the data is unchanged.  Here is what I do for DSLR images

Linear:
Linear Fit
Background Nuetralization
Color Calibration
Deconvolution
HSV Repair
Mild noise reduction with TGVDenoise and MMT
Mild color saturation
Mild star reduction

Once I am happy with the general appearance and the image is cleaned up and calibrated, I will stretch it to Non-Linear

Non-Linear:
Masked Stretch or Histogram Stretch
Set proper Black Point with HT
Additional Color Saturation
Additional Star Reduction if needed
Final noise reduction
Curves Transformation or LHE to increase contrast

This is my general workflow and would be happy on any comments or additional steps required.  Hope that helps

Thanks for the heads up!  I will add it to my list of processing sequence.

Ha, I left out gradient remove with ABE or DBE. Dynamic crop the stacking artifacts then I do ABE/DBE right after linear fit before background neutralization and color calibration.  There are a lot of steps

I'm just learning but I used this as a starting point:

Bill what process do you use for mild star reduction?

Larry, 

I have been following this example and it works very well.
