Photo Editing VS Picture Editing

Wonder on the title...
Are they the same?
I think so.
Whatever it is, this is another skill that i am venturing now.

Ma'am showed us loads of edited pictures, and i was impressed with the changes and the difference of the edited versions as compared to the original ones. Actually, we can do loads of things things to make pictures look attractive and interesting.
I used to edit pictures before this, but the skills were like the surface of the deep ocean. There are many more of this skill that i need to explore and dig until i find the core and usefulness of it. Then what should i do?

What a question!. Of course, i need to apply what i have explored into my courses of life. This is especially regarding my future beloved and 'dream-mission' career which is teacher. I found that photo editing will really help me in transforming dull or so called lame pictures to be childish, colourful and children-oriented kind of pictures. So, the skills like putting effect, changing the background of the photos, adding lights and so on should be applied in order to prepare the best quality of teaching and learning aids and material as regards to pictures.

I am learning, venturing, experiencing and exploring picture editing and i hope to grasp the skills as tight as i could in order to benefit my now and my future. =D
