LED white christmas lights effect

Users mailing list
I plan to take some pictures of some Christmas poinsettias with pine branches around the pot and think the picture would be better if there were white (warm) LED lights in the picture. The problem is that the string needs to be fairly short, and stores have sold out all Christmas lights. So, my next option is to create them in GIMP. Anyone done this and can you offer a genera procedure?

Thanks,
Dave

I'm sure there are people better at this than I am, but I had a
similar problem when I was making
https://shallowsky.com/images/cards/squirrelcard.jpg
and it was quite a few years ago, but as I recall, the steps were:

- Get a photo of a single light. Erase the background so the image
  has just the light.
- Add a fuzzy circle in a color that matches the light
  (new layer, ellipse select, feather edges, fill, then fiddle
  with the layer transparency)
- Add a white speck in the middle where the light filament should
  be if the light in the photo wasn't on
- Flatten this light image and make several copies of it at the
  right size to paste into your image
- Use the Hue slider in Colors->Hue-Saturation to change the
  copies to other colors.
- Paste copies of lights of different colors around the base image,
  and rotate each one semi-randomly.

Then you need the wire connecting them. I don't know how to draw a
realistic looking multi-stranded electrical wire, but you can make a
strangely realistic looking string by playing with settings in the
Smudge tool: try starting with a smudge rate of 100% and a
hard-edged brush. It doesn't look like a real electrical cord, but
at least it looks like a three-dimensional string instead of a line
someone drew in a graphics app.

Good luck, have fun!

Perhaps some LED tape or rope, not specifically badged as Xmas.
IKEA do it, but the bare tape is pretty much generic now.

Reminds me I must do something with a spool of it I have hanging around!
