<p>Hi Gilles</p>
<p>The idea isn't to invert colour but to enhance colour. The
slides have faded and the original colours aren't alive. The
link shows a photo that has faded.</p>

<p>Hi All</p>
<p>I am now trying Manjaro KDE after many years of
Kununtu. Of course I am also planning to transfer (or
redo) my Digikam from Kubuntu to Manjaro. I have
however a photo question that doesn't specifically
apply specifically to either of these programs. As I
said in the subject I hope it isn't OT but as it is
photo connected and I hope Digikam can help as well I
would appreciate the help of anyone who can. If it is
OT the moderators can remove my post and I will
understand.<br>
</p>
<p>I am transferring all my slides (and eventually
negatives) to digital format. I am looking for a
one-click solution (program) that will restore colours
back to normal.</p>

<div>You want mean to invert color ? If yes, ImageMagick is
your friend, especially -negate option:</div>

<div>This can be scripted of course to parse and process
automatically all files from your collection. And of
course, all can be done de facto under Linux from command
line.</div>
<div><br>
</div>
<div>Else, In digiKam, Invert Color tool from Batch Queue
Manager can be used. Create a new Queue, assign items to
process, configure the output options (path, file name,
etc...), assign Invert tool + the convert format if
necessary, and... you can take a coffee.</div>
