There are many differences between Film Disk and digital photography. For most amateur photographers who do not have much. They prefer the comfort, ease of use and low cost of digital cameras and will not return at the age of the film. But understanding the differences can help you make even better images and can also help when debating with friends about the future of cinema.
Here is a list of differences that are important to understand. The differences are shown in no particular order.
The sensor: The most obvious difference between film and digital is the sensor used to take the picture. With a film camera sensitive to light is placed behind the lens. When taking a picture the shutter opens for a predetermined period of time and light reaching the film. The result is a photo “printed” in the film. To take a new picture of the film should be rolled up and a new “clean” film is place behind the lens. With digital cameras a fixed electronic sensor (also known as CCD) is located behind the lens. The sensor is built from tiny light sensitive sensors each representing a pixel. When the shutter opens light hits the sensor, each pixel gets its “value”. Put all the pixels are composed of a photo. To take a new photo of the photo is stored in digital media and the CCD is electronically emptied.
This means a different sensor? The main difference is in the depth of field. Since digital sensors are smaller than 35 mm depth of field of the film will be much higher and, in fact, most compact digital cameras almost infinite. The result is that blur backgrounds can not be created.
The cost of the photo: Photos taken with a digital camera literally cost nothing. The images are stored in erasable memory and thus always be ruled out, at no cost. Also the photos you want to keep can be copied to digital media such as hard drives of a computer. With storage prices lower the cost of saving a photo on disk is practically zero. Film costs money. With a camera that has to pay for the roll of film for developing and printing negatives of the photo. Each time you press the shutter button you spend money.
The capacity: With ever-increasing storage capacity of digital cameras today can hold hundreds and sometimes thousands of photos in a single medium. You can still have a little more in your pocket and change is very fast. The result is that a digital camera has practically infinite capacity. You can take as many pictures as you want and at the end of the day you just have to throw in the disk of your computer. The ability of film cameras “is very limited. A roll of 36 images can only hold 36 photos. After a roll is used changing to a new roll can be time consuming and not easy to do in situations like the dark or a hostile environment. For this reason, many professional journalists have a few cameras on them and instead of changing the rolls turn and use another camera only to miss any opportunity to shoot.
Comments: One of the most important features of digital camera is instant feedback. Almost all digital cameras include a small LCD screen. Once you take a picture, you can go back and look at this screen. The ability to see how the resulting picture looks better pictures. If the image is poor, you can take another. Being able to see the images up on the results in a decision of how to fix a photo or how to improve it up. It takes a lot of guesswork out of photography. With film cameras, there is no way of knowing how the image of the movie will look when printed.
New shooting angles: only a few days ago I took a good photo with my digital camera I have ever had with my film. I shot a cat that was resting in Little Rock. I had the camera in my hand and placed at the bottom, where almost touching the ground and began firing. He probably had 50 or more images. I immediately looked into the camera’s LCD to see my pictures and make sure they were subjected and the cat was in them. The result was a large picture to see the cat on earth. I can not imagine on the dirt floor with a camera to look through the viewfinder and perfect this time.
With digital cameras you can take pictures without the eye in the viewfinder. Aerial shots where the camera rises above the head are much easier to do, since you can always see what the camera is shooting by just looking at the LCD.
Correcting photos: With digital camera images can be corrected using photo editing software. Some skills are built on the correction of the cameras, but many more are available as software packages for PC. With the cameras to film what you get is what you get. After the film develops, it is very difficult to make corrections. Generally, if the corrections are absolutely needed the negative or the printed photo will be scanned (ie converted to digital) corrected and printed again (in a long and expensive process).
Changing conditions: Every roll of film is designed to achieve better results in a specific environment. For example, there are movies indoors and outdoors or movies with different light sensitivity. If conditions change faster than a user must either camera to take photos with the wrong movie, change the roll (and usually lose photos that were not used in the current implementation) or use another device with a different movie that . The results of rolling with the wrong movie can be distorted colors (reddish images, for example), a grainy image and more.
With digital cameras sensor characteristics can be changed instantly for each photo taken. With a click of a button, the camera can be placed in a mode of indoor or outdoor, low light, night photography etc. Some cameras will automatically detect the script and set the sensor mode accordingly.
The myth of quality: It is true that film photography has its advantages in the demand for quality is no longer true. As digital camera evolved the quality of high-end digital SLR cameras is excellent and in many ways better than the movie. When considering the quality, you should also consider quality in terms of composition and the script took the photo. With the capability of digital cameras, the high cost of the photos from scratch and instant adaptability to changing conditions photographers can produce better compositions and more experience to get the best picture possible.
Longevity: We have also looked through old photo albums of our grandparents. The outlook was little AA yellow, striped and simply “old.” Storage of film prints, prints or even the negative results of quality deterioration. Digital Photos on the other hand, never loses its quality. A digital photo will be the same today as 500 years from now. As long as we remember to update the digital media from time to time and save our photos literally make a list of times and not lose quality.
