First create a new layer above your landscape.
Next, change your paintbucket over to the gradient tool, and using
the
preferences at the top of your screen, click to edit the gradient
colours.
One of the presets in there should be called "Transparent Rainbow".
Select this one.
Now drag all the sliders all the way over to the right. Bunch them up
real close, but keep then in the same order they were in to start
with. You want to create a gradient which is transparent for about
90% of its length from the left hand side, with the rainbow crushed
into the remaining area.
Once you've done that, change the gradient from linear to radial.
Now, go back to your image, with the new layer selected, look at the
landscape and visualise the rainbow. Imagine it as a sweeping curve,
and try to visualise where the centre of that curve would be.
Place your cursor on that point, click and drag out the gradient tool
to
where you visualised the outside of the rainbow to be. Release the
mouse button and you'll have a rainbow.
The rainbow isn't very realistic yet. It's colours are too bright and
harsh.
So simply reduce the layer opacity to a level between 15% and 20%.
Use your best judgement here.
Lastly, you need to do something about the ends of the rainbow.
Rainbows in nature fade out and the ends disappear into nothingness.
So set your eraser tool to a good wide radius, and drop its hardness
to
zero.
Now simply dab the eraser tool on the ends of the rainbow until you
get the fade-out effect you want.
If done right, the effect should look something like this.

Thank you for the procedure and the example. Even then the rainbow is
not realistic enough to my taste. HWtn

Fat Sam gave you an excellent example of what could be done and offered
you the proper procedure to follow!

By a little tweaking, IE: Gaussian blur, hue/saturation, free
transform, levels, curves, move tool, adding another layer of mist or
rain clouds if needed... you can make an absolutely real looking rainbow
.... even copy and paste, then free transform if you want double or
triple Realistic looking rainbows..

If all you understand is copy and paste and you cannot use your
imagination and surmise how to tweak the example provided by Fat Sam
into something that looks more realistic, then you should probably learn
a lot more of the basics before tackling this project.. and Google,
either Web or Images, is your friend..

If you do understand the procedures he outlined then you might go to:
http://www.atoptics.co.uk/bows.htm for different examples and views of
the real things that you are trying to emulate or duplicate-- Then just
do it!.. as outlined by Fat Sam..

Kudos to Fat Sam for his giving you all the steps needed for obtaining
Quick N Easy REALITY... All you gotta do is try it, you may like it!
