As some of you may remember (from the topic "challenge for a realistic waterdrops script"), I was -and I still am- interested in having some automatic way to draw water drops on fruit, leaves, flowers etc.
The excellent Graechan's script "Water drops Rel4" is very well suited for flat surfaces (if used on a table gives fantastic results), but I was mainly interested on almost spherical drops.
I tried to adapt that script to my requirements, but I didn't succeed really (you have probably seen an example on the same topic).
So, during this summer, I tried to write down a completely different script, using specific brushes.
I needed to have one patient and efficient contributor to:
1 - deeply test the script
2 - create (provide) interesting brushes to use with
I was very lucky! Issabella accepted to help me on this (sometimes nice, sometimes annoying, but always hard) task. So a very big thanks to her!

Logic of the script:
-the script works on a selection, if none on the full image
thus, if you want to avoid bubbles being drawn outside the area of your interest, you MUST do a selection.
-the bubble layer is created on top of the input layer (bubbles on transparent layer)
-the bubbles are painted using up to 3 different brushes, in random locations,
with a user specified number of repetitions
-only the bubbles which are inside the selection are preserved
-on top of the bubble layer an invisible map layer is created from the input layer, to apply some distortion

The script is "general purpose": in practice, you may draw any kind of brush, not just bubbles and you may create and select other brushes as you like.

Please remember: it NEEDS big brushes on BIG images, it doesn't resize the brushes; even more important: it NEEDS small/average brushes on NOT-BIG images
(while small drops can even be acceptable on a big image, the opposite is almost not true
(big drops on small images are in the majority of the cases bad!).


Also consider: the 3 default brushes predefined in the script are:
- rounded-drop-25A
- rounded-drop-40A
- rounded-drop-50A
They are the last 3 in the group ISSA_Rounded transparent Bubbles
Thus:
- either you activate AT LEAST that group of brushes BEFORE calling the script
- or you accept to get a warning by the script when calling it, then select from your brushes
other 3 different ones

By default, the script does not flatten the image: this allows the user to apply some manual
modification, the easiest of which is: in case you like to increase the luminosity of the drops,
you may simply duplicate the drop layer.

After Issabella's very effective contribution, I'm now in a position to post here:
a) the script
b) some sets of drops brushes
c) samples of use (all based on pictures found on an internet site which explicitly says:
"Public domain images, royalty free stock photos, copyright friendly free images.

I have run the script twice. First I've selected the main rose and I appied the script with a sorted drop selection, then in Select - invert, I've run the script again. Applied to this new layer Gaussian blur at 5px and lowered the opacity. I love playing with this script. :) :tyspin

Very nice dinasset and Issabella, love your water drops, thanks for sharing. It looks like a lot of work to get all these bubbles.
Issabella, very nice job on the rose.
