IceBeam-lighting

[ 作者来源:shiver7/surreal-utopia 编辑整理:PhotoShop资源网 更新时间: 2006-07-18 录入: 黄叶飞扬 ]

    Before we start, here's a few things to keep in mind:
    1: The point of this tutorial is to teach you a method by which to make your own beams. Deviate.
    2: Beams are overused these days so be original- this beam I have made in this tutorial is not original.
    3: Think outside the box- see if you can apply things you learned here to other parts of your pictures.

    Okay, lets get started. I challenge you guys to have your beam pointing in a different direction than mine- this will add complication but will make you better in the end. Start with a blank canvas and remember to create a new layer for every element you add. This will make it easier to modify in the end if you see a minor error.

The point from which the beam originates is where you will need to do a little brightening. If you have a bright light source, then the areas around it will need to be lit by it.
     Select your airbrush tool and go to the top where you see "mode:" and change that to Linear Dodge. Then, with a low flow (around 8%), go over the source area and brighten it up a bit...be careful not to overdo it.
     Note: The size and intensity of your beam will govern how bright and widely your 3d object will be lit. Don't dodge your 3d object as much as I did if your beam is humongous.

     Now, keep your pen path there and select your airbrush. Make the brush size about 100 (this all depends on the size you want) with a flow of about 15% and go back to your pen tool. Right-click with the pen tool on the canvas and select "stroke path". In the drop-down menu, select 'airbrush' if it is not already selected then hit 'ok'. You will see that the path you made with the pen tool has been neatly brushed. Still keeping your pen path there, go back to your airbrush and decrease the size by larger to smaller increments while keeping the flow at 15%. Your last stroke will be the core of your beam. In this case, I used a size 3 brush at 50% flow. If you don't understand how I got this beam to glow, see my 'glow' tutorial. (if it's done yet).

If you want your brushing to fade out as it goes out, use your eraser at a low flow with a large brush and erase the tips where your brush abruptly ends so they fade out.

Select your airbrush and make it like a size 1 or 2 with high flow. Stroke the path with the pen tool like you did to make your beam (but this time it's only using one brush size).
     If you lightning is too dull, duplicate the layer and merge the top one down. If it's too bright, decrease the opacity of the layer it's on. You may use the same erasing technique I taught you in the step above to make your bolts fade out.

Click on the brushes tab in the upper right of the screen and go to 'scattering'. Put the count at 1 and you can put the scatter amount as high as you want...this is where you kinda get to do what you want.
     If you have no idea what I'm talking about, you can always just individually click to create every particle.

   8: End notes: There are about a billion ways to make a beam- this is only one. Remember that the beam is overdone so be origional
     Ways to deviate from my tutorial: Curve the beam, don't have it go off-screen...have a projectile at the front of it shooting towards something, add color, mess with the lighting and particles.

     I hoped this tutorial helped- please tell me what you thought of it and how I can make better tutorials in the future.
