Taking the photo via WEPS ->Torpedo Attack -> Take Photo works great.
You still need to lock a target through the UZO though before it works plus you can't really see anything on there because of the zoom level. But I reckon it's safe to say that taking the photo through the binoculars should work ok. I did notice however that it does register as 'objective complete' when you take the photo from the bridge...
