First digital camera
Instagram is the most used social network of photography in the world, with millions of active users every day, so creating a space in this network can be a great satisfaction, both personally and professionally.
During special occasions, for example, dinners with friends and family vacations, it may happen that we take pictures, to capture images that you can take to physical format, the action you do by instinct is to take out your cell phone and activate the camera.
Nowadays it is easy to always carry a cell phone in your pocket or purse, besides having the basic functions to receive and make calls, in a small space we also have a device that allows you to control email, surf the internet, find a street using a gps and as if all this were not enough we can also take pictures.
With the phone we can make some settings such as: zoom (something I do not recommend), activate the flash (something I also do not recommend), you can focus by touching the screen etc…
In what year was the photographic camera invented?
This development consisted of a great amplification of the effect of light, so the exposure time did not exceed 30 minutes. The fixation was obtained by immersion in water saturated with sea salts.
In July 1839, another Frenchman, Hippolyte Bayard, discovered the means of obtaining positive images directly on paper. A paper coated with silver chloride was darkened in the light and then exposed in the camera obscura after being impregnated in silver iodide. The exposure time was from thirty minutes to two hours.
In 1871, another Briton, Richard Meaddox, remedied this problem by replacing collodion with gelatin, a procedure perfected by Charles Bennet who demonstrated that gelatinized plates acquired a great sensitivity when kept for several days at 32° C. Gelatin-bromide plates could not only be stored before use, but their sensitivity was such that exposure did not exceed a fraction of a second.

Digital cameras are specially introduced to make photography easy to recover files from a digital camera. The traditional huge camera and the setup that is required to click a picture nothing else is needed. Today anyone can click photos, record videos, audios, etc. in just a few seconds as all it requires is a simple press on the playback button provided in digital camera/click and become a photographer. Moreover, when you capture the image it is stored in the memory card that is placed in the digital camera retrieve files camara. However, the best part of digital camera is, it offers immediate results. It means that you do not need to adopt a long procedure to view a captured image, unlike the old cameras, as you can view images and videos shortly after the digital camera captures.
There are a number of advantages that may be associated with digital cameras, such as quick and simple to use results, superior image/video quality, portability, etc., but there is a disadvantage as well. As these cameras are prone to adverse data loss situations, you can unintentionally or intentionally delete files from a digital camera and suffer data loss. Honestly, it is impossible to avoid data loss in unpredictable case, but a good recovery tool can help you recover files from digital camera on your Windows computer.
Vintage camera
The history of digital photography is much more dense than it may seem, with a huge explosion thanks to mobile devices.
The main difference with “analog” cameras, with which they have coexisted for a few decades, is that digital systems do not need a film to store the information, there are no chemical processes to record the information and transform it into a photo.
Here the photos are recorded with digital sensors and integrated circuits, another very different thing is its storage, since initially it did not begin to record on digital media, there were no memories as we know them now. What was used were tapes, magnetic media.
Without going too much into the types of sensors or how they work, we want to explain that this sensor plays the role of the photographic film of the previous cameras. How? Well, it is composed of semiconductors that capture photons, the greater the intensity of light, the greater the electrical charge. Each of these photosensitive cells corresponds to a pixel.
