Well . .anywhere in Ladakh is a photo haven. You can go to the lakes but I strongly suggest Pangong Tso. You can do without Tsomoriri as its quite far away. Go to the gompas as there are many photo opportunities. Other places include Lamayuru, Nubra Valley and if you have time, do the Manali to Leh stretch. Let me know if you need travel assitance as I have some contacts in Leh.
