i want to use the mighty tools of RawTherapee to tweak my weak scans of old material from archives. Those scans are unfortunately not Raw and they have been taken for a long time also. Mmh, but we will see.
First step is anti-vignetting because at the edge from this library-scanner always some light (resulting in gray areas) was put to the scan. I want to use this filter vignetting and found some positions of the sliders
intensity - 0.44
for the left sides of a book.
How to tell the filter that now the virnetting goes from middle to left (because we show a right side of a book)? Sure i can turn the page to 180° but this is much harder to control, because the whole letters are turned up and this is quite desturbing.
Next step i sharpened with
saturation to - 100 (because it will become a bw-publication)
ligtness to +50
contrast + 50
blackworth set to 22000
but the results are not enough. Something in the workflow i am missing.
Can someone help?
How to improve my results?
Thanks in advance for any tip,
