Hi everyone,
I just tried to use the Wayback Machine to see if I could find old forum information. Click HERE to view what the website looked like back in 2021. Oddly some of the important links (IMO), are banned by Wayback.
For a wealth of information and tutorials, albeit older, click HERE.
Click HERE to view Doug Pardee, the original developer’s LZ Wiki Github page. Pay particular attention to the right hand side links, with the Project DCraw and the Tone Curve Math being the most interesting to me.
I hope this helps someone.
Steve
