Normally I can differentiate a photo by checking on it’s EXIF (Exchangable Image file). How you differentiate them then?

I’m so confuse about taken a photo by DSLR but it result like compact camera. How am I have to make my photo looks different from my Lumix FX30.

Please help.

ps: All the photos of my Travel Journal taken by Lumix, at that time I don’t have my DSLR yet.
