I have this image:
I need to isolate the libellula and "restore" the transparency of its wings, the areas highlighted here:
I haven't problems to isolate it but how can I restore the transparency?
The image must be saved as PNG with alpha channel, without the background.
I haven't enough knowledge about GIMP and image manipulation, I already tried with the rubber tool adjusting the opacity but the result is very bad.
Thanks a lot!
