The main difference between digital and film camera is the storage option. In film cameras, captured photos are stored in the film itself whereas photos are stored in a memory card in digital cameras. Digital cameras has an image sensor . This sensor helps take and store photos. This sensor is absent in film cameras. If the film is exposed once it can not be used again in film cameras. Memory card is re-usable Photos stored in memory card can be erased and then it again be re-usable. Film has to develop by using different kinds of chemicals in film cameras while we can see photos instantly either on the computers or in digital camera.
A darkroom is required to develop photos captured in film cameras and this process is complicated. This process is much easier if photos captured in digital cameras. We can easily print digital photos from computer. Digital cameras require more power than film cameras. Generally rechargeable and non-rechargeable batteries are used in digital and film cameras respectively. Film cameras response quickly. Its takes less time than digital cameras to focus. The fraction time between to focus is also less in film cameras. Now lets discuss about photo quality between digital and film cameras.
Photo quality is depends on equipment in digital cameras whether film cameras has no variation. All film cameras are same. They provide same quality photos. But in digital cameras photo quality depends on megapixel, sensor and on many other things. Today in market , we found 1 to 50 or more mega pixels digital camera. Digital cameras can be many types, such as DSLR, SLR etc. Film cameras is only one type. Lens and scale is also a great difference between film and digital cameras. Professional photographers are demand high quality cameras that why there first choice is digital camera.
The other most important contrast between digital and film camera is tonal range. Tonal range is number of grades of light to dark in photo. Digital cameras are limited to 256 grades whereas film cameras have unlimited grades. Film cameras are ahead in tonal range. So they can produce limitless grades of light to dark. More apparently, film cameras can capture all dark view, not matter how mild it is. On the other hand, digital cameras produce bright view instead of mild darkness. We already know that, in digital camera photo quality depends on megapixel.
So here is a question about its work, and also how grains work in film cameras. More mega pixel produces more sharp photos. Grains also do the same thing in film cameras. Brightness, hue, value, saturation etc are also same in digital and film cameras. Both has required lens, both has same shape, both can produce monochromic and color photos. In film cameras, grains speed depends on speed of the film whereas megapixel can be troubleshoot from menu. More people choose slower film camera. A slower film camera is equal to 8 megapixel camera. Both in film and digital cameras megapixel alone cant sharp photo quality.
Some special effect and zoom etc can changeable in digital cameras while film camera does not has those option. Aparture is almost same in both type of cameras whereas shutter is same. Size of photo cant vary and lens is obvious equipment of both cameras. In conclusion, we can say both cameras are important. Because the importance of cameras are vary from person to person, profession to profession. Professional photographers generally choose digital cameras and again sometimes they need film cameras for specific reason. Both film and digital cameras has lots of fan. It just like CD and cassette, both are important.
