Liz Kirby, an Environment Artist at 343 Industries, and CGSociety have recently shared a tutorial on how to create high poly vegetation in ZBrush, a rose in this case, without the use of photogrammetry, other tools and custom brushes or alphas. All you need here is just ZBrush. Basically, it is an alternative solution for those who have limited resources.
Here is a small piece about the beginning of the sculpting process to get you interested:
I like to start with the flower at its most common state: alive and healthy, neither dying or budding. Buds are usually their own, unique sculpt, and decay is much easier to add than it is to subtract. For a rose, start with a plane and mask the general shape of its petal.
Once masked, go to Tool > Subtool > Extract. Edit the thickness as you see fit, and then click Accept. This will create a new Subtool from your mask.
From my rose petal extract, I add the petal’s basic form with three brushes: Move, Fold, and Pinch. Using the Move brush, you can add the larger shapes to the petal, then use Fold (with a low intensity) to add lips and pinches to the petal (be sure to smooth these folds). Pinch can then add sharp creases or polish the edges.
