If I may ask, what program do you use? Photoshop CS5? :O nice tutorial by the way!

I using Painter 6. but any program can do this technics I think :)

think you can do an underwater lighting tutorial?

Hmm... ok, I will do that one.

Could you elaborate on why white looks different from translucent? What is the idea behind step 4?

It's the difference that through lights or not. Step4 make looks more glossy and transparent.

I know 'what' it is, but can you explain in detail how reflection/refraction produces what we see there?

On step 4, I know but what is the thought process behind it? Why does doing what you did make it appear more transparent/glossy?

Hmmm, maybe easy to understand by diagram better I think. http://twitpic.com/4nlzzp
The whole method is purely based on my experience on observing on transparent objects, I afraid I can't give you the scientific explanations.
but maybe same as mirror, glossy things are reflect lights without dim because surface is smooth, same thing as that. Transparence things are looks more transparently too because surface is smooth.(example: normal glass and frosted glass)

I did a sketch to try to figure it out, I think this explains step 4: http://dl.dropbox.com/u/20455920/water.png

The water is the dome. It could be a square too. You'll 'miss' ground at the edges because of the refraction.

this could come in gandy

Oh thanks! :)

Ohh, neat! Thanks!

You're welcome :)

Beautiful :3

Do you have any other tutorials?

yes, I think I wanna draw other tutorials near future.

I love this one :) It will sure become useful here ^^

Thanks! :)

Ohhh, now it makes more sense thanks a bunch

You're welcome!

Looks great! I'm no artist, but, I'm tempted to try this out all the same.

It's so fun I think :)

mekara uroko XD

"The scales fall from one's eyes" oh thanks!

ooooh.. ty.. me think me gonna try it out sometimes ^^ ty ty ty *hugs*

It looks like it will be effective enough of a tutorial for a few people to improve on their skills with.

Interesting technique! I think I know how you do your wet skin reflections now from this. Very useful stuff, I'll give it a try for my next batch of art.
