3)What is the difference between analog photography and digital photography?
Nowadays,digital photography has been more popular than analog photography.
Analog photography can be produced in the dark room.And we cannot see the photos right away.It is interesting that someone still like using the analog photography they enjoy the surprises when they finally wait and get the photos.The films are easily to damage,too.We need the skills of using the camera in order to take nice pictures.




Digital photography,however,the photos are saved in the sd card.We can see the photos immediately.
We may not need the skills of using the camera beacause we can edit the photos by using the softwares.

There are different pixels of digital cameras that we can choose. But for traditional cameras, the quality of the photos highly depends on the film.The colours of the photos of digital cameras are sharper. Traditional photography is good for the people who have professional skill.On the other hand, digital photography is more easy to use for most of us.
