Thanks. I'll take another look.

Thanks fwm42. I am following the procedure from the fft notch filtering example. In my previous post twigs was replaced with logo - my test image. All I want to do is remove \ from the syntax and put each expression on a single line and avoid newlines - this was simple enough with the first two conv...

I'm attempting to reproduce the notch filtering demo on the fft page and playing with mask creation ATM - the twig image example. How should I write the last line as a one-liner? convert LOGO.png -fft +delete -colorspace gray -auto-level -evaluate log 100000 logo_spectrum.png convert logo_spectrum_m...

This was the best I could come up with. Suggestions for improvement? Perhaps better mogrify contrast settings. -normalize does a different thing in display and animate and I would like the animation and editing windows to look the same. #!/bin/bash #ifs.sh # A blink script # testing only # rm -f *.t...

The problem with using animate is that frames cannot be deleted. In that File Delete is not available. animate on my version of IM does not accept -contrast or -normalize which I need to display what are otherwise near linear images. I imagine this is a bash scripting question - closing the display ...

Hi. I want to keep looping files until the display window is closed - space bar forward and backspace backward, ad-infinitum. Edits follow... Presently, the loop completes 3 times and closes. Version: ImageMagick 6.8.9-9 Q16 x86_64 2016-06-01 Should I be using animate instead? files=*.ppm for i in $...

I'm not sure how to tackle this but the operation will be on the final image and orientation will not be an issue. The colour and intensity of the offending pixels is significantly brighter than the remainder of the image. If the hot pixels are mapped and averaged to the surrounding pixels using int...

Not sure what happened there. Corrected in post.

I am attempting to stay as linear as possible for the workflow, as follows, then convert to sRGB. I don't want any adjustments to the images - realistically as little as possible. Post processing external to the calibration script. I checked the dcraw man page. These are the options used in my scrip...

Thanks.
Typo corrected in post.

I have left out the in between processing. So between separate and -combine the files are subtracted and or divided as required.

Is there any advantage then in a linear dcraw output if the files will only be subtracted and divided between -separate and -combine?

The tiff files are converted RAW using dcraw -4 option with a view to retaining the raw data as much as possible. This works well when converting to grayscale, but not sure of the advantage when working in color, in which case the following syntax IM v6.8.x.x? convert input.tiff -separate %d.miff co...

I want to check the syntax is correct to perform the following operations - the examples adapted from the colour space pages. The workflow is linear to sRGB with no exposure, brightness, gamma, saturation adjustments. separate RGB.tiff image into R G B channels. Process each channel and combine as s...

I might need some help to get started and will start a new thread - thks

I have almost completed a bash script to automate the current process using arrays to sort images into temporary folders progressively processing and moving and deleting files. I take it -clone parenthesis will eliminate a lot of processing which is quite intensive, given that eventually the script ...
