You can act as an official camera man voluntary within this 員工旅遊員工旅遊, and take a lot of photos for all members. You can show your kindness to all people, and get chance to touch with 仰慕已久的美眉 easily.
Then you can get more chances to capture her silently, if she is smart and note that you are always focusing on her actually & she may ask you... You should take a deep breath & be strong, you have to show your honestly & tell her \"對不起! 但情不自禁地拍了她的照片...\"
And, then liberally invite her & some of her friends to take photos within the trip; afterthat, you can have another chance to date her to show the photos in future.
Of course, you will have risk that she feel unhappy for your captures & reject you... but Love is really need to take actions & risk, but you have to try... otherwise, there is no good result & happy ending.
