I love photography.  What is your favorite hobby?
1_Wizard
Photography is absolutely one of my favorites too! It's both a hobby, a science, and even an art arguably.

Definitely a science because of the chemistry of photo developing.  I love taking pictures of nature.  What are your favorite things to photograph?
1_Wizard
Probably nature and birds. One thing about photography that is great is that it is employed in so many fields, like science and manufacturing.

That is very true.  I really like birds, too. Especially birds of prey such as falcons and hawks.

Me too, they're so fierce looking. For a while I never knew what a negative was for, but its to create a positive image on a paper base.

Do you remember when we used to have to take our film to stores to get developed?  I did not know that was the purpose of the negatives.

I know right? It's crazy how far we have come to now having electronic image sensors instead.
