Pearl Problems
Hi all! I'm attempting to replace the icing on the side of the cake with these pearls; but the problem is that when I distort the pearls in any way to get them into perspective, they lose their roundness and believablility. Ultimately, the cake will be made out of pearls, diamonds, and other jewelry as a promotion in a special cook book section of the newspaper for the jewelry co. But if I'm having this much trouble with the first "ingredient" on the cake; well, I think I'd better come up with some other, more managable concepts for the company...

Here's my attempt so far:

Here's the original. I've roughly cut out the pearls, if anyone would like to take a stab at this tricky little headache.

Re: Pearl Problems
You could try creating a custom brush from a single pearl and using size jitter to draw them in perspective. Perhaps create a path and stroke them along it?

Re: Pearl Problems
ooh...That's a really good idea! I never thought about using a brush with size jitter. Currently, I was using two or three pearls and cloned them individually. The layout so far looks like a scrap-book of pearl images with a cake background!

Thanks David!

If the pearls don't fit there, why not try moving them to the vertical pane of the cake, using a strip of three pearls in a vertical line, and start at the back, moving foward with a new layer on each strip?

Note that, in Perspective, a sphere stays a sphere, it does not become and egg... I think the only thing that you have to concentrate on is the lighting as the hilites will subtly change on the pearls... I'll try and make an example...

Re: Pearl Problems
Here's my take on it.

1. I oversized the document so to be able to work bigger to crop later. I found the perspective center of the cake (red ellipse) and located one Round pearl.

2. Free transform the Pearl. Move the center of the 8-handle box on the center of the ellipse. Then pull the low center handle of the box while holding the alt key until you get a second row position (you got to eyeball this one...). Press enter to accept Free Transform and then Undo before soing anything else. Right after that, ctrl-alt-Shift-T will redo what you just undid, but will reproduce the Pearl instead of just moving it. Doing it once more will create the third one.

3. I created (eyeballed) 3 other ellipse aligned on the center of each of the Pearls to help me align the other rows. I just copied each pearl individually on its own ellipse, not changing the size (adjusting the size is not necessary as it would not make that big a difference).

4. Then I croped back to the original document size.

The thing missing, is actually the reflexion of the surrounding pearls on one individual pearl. This could be drawn on the original pearl maybe. The 3 guiding ellipses are tricky; you can see mine are not following the cake's shape as exactly as they should... ;( Good luck and let us see how you did!

Re: Pearl Problems
I think that the main problem here is that the surface having the pearls applied to it is Vertical, not Horizontal. Perhaps the cropping of the image does not clearly define the plane?

Re: Pearl Problems
Woops... You're right about the vertical wall. I didn't notice. Mmmh... be back in a while...

Re: Pearl Problems
Thanks everyone for the helpful advice! Pierre, your technique ended up working perfectly! They ended up choosing a picture of a slice of a chocolate cake to put the jewelry on, though. And after all that work! Oh well...I guess I should ask for approval on the image first, before I begin modifying one they just threw at me as a conceptual photo for the idea!

Is it possible for you to show us what you ended up with?
