Fun with light
In this GIMP tutorial we will transform this stock bulb photo into a switched on 2watt? light bulb :).
Getting started

Before we start this tutorial, your going to need the Light bulb stock photo I found off sxc.hu But I already cut it out so you can download it here.
Step 1
Open a new 1024x768 image. Grab the Blend tool, change your foreground color to 73aeff and background to black. then in the tools options set your Gradient to FG-BG(RGB) and shape to Radial.

Now apply the blend tool from top center to the bottom of your canvas to get a nice radial background *tip hold down CTRL to get a straight line when applying.

Step 2
Next insertour bulb photo into our image. as you can see the bulb looks totally wrong thats because it should be transparent right?

Will fix that by changing the blend mode to Multiply, and then duplicating the layer and setting the mode to Soft light giving it better detail.

Step 3
Now will need to modify the "Tungsten filament" wire (got that from wikipedia) to a switched one, will use the path tool for that. Create a new layer, grab the path tool and go over the wire by applying points along its length.

Step 4
Next change your foreground colour to Yellow fcff02. then go to the brush tab and select "Circle fuzzy (19) brush. then go to your path tab or dialog and right click on your path and in the menu click on Stroke path, in the stroke path window select "Stroke with a paint tool".

You should have something like this
Step 5
Change your foreground colour to white and in the Tools options change your gradient to FG to Transparent, and shape to radial.

Create a new layer make sure its transparent, and apply the blend tool from the wire to lower bottom of the bulb.

Set the layer to overlay and you should have the same out come as mine.

Step 6
Its still not bright right?. no problem, Grab the Ellipse Select tool and draw an oval shape in the top centre of the bulb.

Create a new layer, go to Select>feather set it at 150, then go and grab the bucket tool and fill the selection with solid white. finally set the layer mode to Overlay

Step 7
The light still needs adjusting, will use the Free select tool, but first adjust feather edges to 100 in the tools options and then grab the Free select tool and draw around the bulb.

Create a new layer.grab the paint bucket and with your Foreground color set to white apply it over

Step 8
Now will add a little flare effect to our light, first create a new layer, fill it with black then go to Filters>Light and Shadow>Gradient Flare.
inside the Selector tab select Hidden_Planet then go to the Settings tab change the position to X:504 Y:248 and Radius:314.4.

Covert the image to Black & white by going to Color>Desatruate, and select lightness.

Step 9
Change the layer mode to Addition and opacity to 31. that's it!

You could add some more creativity into this and the possibilities are almost endless :)

:(
Re: Fun with light

Re: Fun with light
I'm very happy to see a nice and well done tutorial like this. Good job Gimper!
Re: Fun with light
appreciate the nice comment :)
Re: Fun with light
Very nicely done, great inspiration.
The whole site is full of very useful tips and tricks.
I have been switching to GIMP for 2 days now from Paint Shop Pro.I refuse to use Photoshop because I think its too expensive, not that that would be a problem on today's internet, but if you want to make professional designs you shouldnt be caught using illegal software. You have proven GIMP to be a worthy alternative.
Thanks to your website and yours alone I have been able to get the hang of the gimp.
Thank you.
Re: Fun with light
Hi! I stopped at step 2. I cant insert bulb in my New Layer. I have downloaded bulb from here http://www.sxc.hu/photo/839958. But it have size bigger than 1024*768 and overflow my image. In addition, i cant cut only bulb from this photo...and bulb goes to my picture with white background. Please, help me! :)....and sorry for my bad English.
Re: Fun with light
i already posted the link to the cut out bulb but it seems you missed it. here it is http://gimp-tutorials.net/tutorials/turn_on/bulb.zip
Re: Fun with light
I already downloaded this archive with .xcf file inside... but i want to know how i can cut out bulb from this image (http://www.sxc.hu/photo/839958) by myself...or this question is outside the scope of this tutorial?
Re: Fun with light

Re: Fun with light
In part 6 when i poured the paint the area in the circle became pure white and i had in what ypu said..and i can't make the flare colorless.
Re: Fun with light
make sure the layer mode is set to Overlay
for the flare follow the step "Color>Desatruate, and select lightness"
Re: Fun with light
When I make a path on the somethingamajig string and attempt to stroke it, it looks like a different type of yellow. My opacity is 100, I'm using Circle Fuzzy (19) and it's scaled at 1.12, and I'm using fcff02.
Re: Fun with light
make sure you have the layer ordering correct, if you wan't more help post a screenshot in the forum section for us to see.
Thanks Gimper. Great

How are we to insert the light bulb?
Re: Fun with light
simply drag the photo into you're canvas.
Re: Fun with light
Dear Gimper, I got stuck in step one. Using Blend (from Tools) and Gradient (from Dialogue), I could only get the image 'blended' but without the important 'radial' effect because I could not find 'Shape-radial', as shown in your tutorial, in either the Blend or the Gradiant dialogue box. I am using Gimp 2.4. Is it a different version from yours?
Re: Fun with light
Hi, Did you check the image in step 1? notice the Shape dropdown option..
you can see it in this image http://gimp-tutorials.net/tutorials/turn_on/1.jpg
Re: Re: Fun with light
Thanks Gimper, I finally found it after more careful searching. Its different from your dropdown menu, but 'Shape-radial' is there. Guess thats a common problem with different versions of Gimp - menus are differently located and designed. I think now I can proceed with your wonderful tutorial - thanks a lot !

Glad you got it worked out.
