Help with glass technique: White outline on black and vice-versa

Hi all,<br>

I have an idea in mind and would like to learn how to photograph a

glass as a white outline on a black BG or a black outline in a white

BG. <br>

Could you describe how to achive it or point me out to some

resources? <br>

Thanks a lot!,<Br>Gerard.

Do you mean something like this...

Yes, EXACTLY! Thanks a lot for the sample. I'll inline it here for the clearness of the thread:

Could somebody explain me the technique involved? <br>

The white BG seems like a big diffused light source such as a softbox or a scrim, but how do you get the black definition on the crystal features? <br>

The white outline on black should be somehow backlighted but that one beats me.<br>

I would love to give it a try today if somebody can point me out in the right direction.<br>

-regards, Gerard.

Andi, <br> I just noticed that it's <B>you</B> who made these images. Their are great, and indeed the kind of look I'm seeking. Could you share the secret? :-) <br>-regards,<bR>Gerard.

Blackline: Softbox behind the glass.

 

Whiteline: Black background, softbox on each side. The positioning and shape of the sofboxes will define the shape of the whiteline on the edge of the glass.

Gerard,<br><br>Just yesterday I was reading about this technique in the book <a href="http://www.amazon.com/exec/obidos/ASIN/0240802756/qid=1112888139/sr=2-1/ref=pd_bbs_b_2_1/002-9078784-1265601.html">"Light Science & Magic"</a> - Fil Hunter and Paul Fuqua. Chapter 7 - "The Case of the Disappearing Glass" illustrates the techniques using both lighting diagrams along with the completed photo. I found the explanations concise and an excellent resource for this and other situations.<br><br>
