Reduce the stars size - Duende - 01-18-2021
Hi, I think this is the right place to post.
I have this image and I want to reduce the size of the stars, but without the small ones disappearing. I mean, there are stars that are very big and those are the ones that I want to be smaller.
I have been trying several things and the only solution left is to go star by star manually, but before doing that maybe someone knows how to achieve this in a faster way than doing it manually.
Thanks a lot, I hope you can help me.

Not so easy because of the small size. You can try:
Scale the image up by 200%
Filters -> Generic -> Erode which grows darker areas shrinking the tiny stars to nothing.
then reverse
Filters -> Generic -> Dilate which grows lighter areas (the larger stars back to original.
then scale the image back. Scale 50%
Which gives this:

Thank you very much rich2005, I was waiting to see if someone else would respond.
It seems that the image you shared is not exactly what I need, but the erode filter is very useful. Surely I have no choice but to modify the image manually but using the erode filter can save me a lot of work.
Thanks again.
