Default kpca and svm

After learning your kernel method, I have a question. When I do face recognition, there are two different ways. The first one is to extract kernel PCA and then use SVM. The second one is to extract PCA first and then use kernel SVM. Both of them are using kernel method, but what are the differences between them?
