pursue the topic further.
The principal difference between film and digital is that the image taken on a digital camera is first generation whereas a scanned image is second generation. This means that scanned film images will degrade slightly from the original - although in skilled hands this is slight.
Of course digital images are processed instantly on your own computer and without the requirement for services of the chemist or photo-developers.
The fact that there is no “film” cost does not place cost restrictions on taking pictures. This in turn means there is no financial penalty for experimentation. You are free to take what you like and make as many mistakes as you like.
Another important consideration about digital imaging techniques is modifying the image. You can easily change a digital image on a computer. But of course, digital image modification does not require the camera to be digital. Top professionals quite often to use film to take the photographs as the primary source and then scan these in to the computer and perform the modifications digitally especially when using larger format film cameras.
Some people believe that digital photography improves the photographer because you can afford to experiment and make mistakes. To be able to get the same level of photographic technique experience with film would cost quite a lot of money.
Many professional photographers have already switched over to digital using up to 15 mega pixel (or higher) cameras and it is difficult to detect the difference between these images and those from high quality conventional 35mm film cameras.
