Spanish actress Penelope Cruz has discovered her photography hobby is a difficult one because she chooses heartbreaking topics.

During a recent visit to Kathmandu, Nepal, the VANILLA SKY star snapped the feet of refugee children who had escaped across the mountains from Tibet, and now she's planning a new exhibition after taking photos of troubled youths at a California hostel.

She says, "When I was in Kathmandu photographing kids who had escaped from Tibet, some who had escaped by walking across the mountains, I photographed their feet. Some had lost toes because of the snow.

"I have to control myself not to cry. Not out of pity, but seeing how tricky life is and how hard it is to make the right choices."
