What is digital photography?
Digital photography is a process of capturing still images through a dark room, very similar to traditional photography, but instead of using photosensitive film and developing chemicals, it captures light through an electronic sensor made up of units photosensitive.
In this way, the captured images are converted into electrical signals that are stored in an electronic memory , following the same formats and communication protocols of the digital memories of computers and applying various format and compression mechanisms to the photograph taken.
Digital photography is a revolutionary technological advance that forever changed the photographic industry and allowed the rise of digital visual arts . In addition, he also democratized this art and made it accessible to anyone.
History of digital photography
In 1975, Steven Sasson, an employee of the Kodak company, developed what is considered the first prototype of a digital camera .
The main feature of this camera was that it did not need a film to work but an electrical sensor that could record a small monochrome image.
In 1978, the prototype digital still camera design was patented by Kodak . This was for still photography with a resolution of 0.01 megapixels and weighed 3.5 kilograms. The process of digitally saving the image was extremely slow: it took 23 seconds to save a black and white photograph on a cassette tape and the same time to retrieve it once stored.
This was the first antecedent of digital photography, but it was not until the 1990s that Kodak began to market the product .
In 1991, the company released its Digital Camera System (DCS) that included a 1.3-megapixel sensor with a Nikon F3 camera body. The camera had a separate unit connected by a cable in which the photo taken could be viewed and archived.
This was the beginning of the evolutionary path of digital cameras to the ones we know today that have enormous resolution capacity and speed of shooting and saving, in addition to other modern capabilities such as digital zoom.
Characteristics of digital photography
Image size is one of the main characteristics of digital photography. This aspect, along with the resolution, has changed a lot over the years, but today the measurements are standardized and there are hardly any cameras that reproduce less than 15 megapixels.
Sensitivity is another characteristic of this type of photography and its function is to produce a correct result with natural light, which makes the use of additional light sources less and less necessary.
Finally, perhaps one of the most prominent features of digital photography is the ease of producing them, you only need, at a minimum, a cell phone to capture images and a device such as a mobile phone, computer or tablet to store and share them with others. the world.
Advantages and disadvantages of digital photography
Now that you know what digital photography is all about, it’s time for you to understand its advantages and disadvantages.
Advantages
minor costs
By dispensing with the use of photographic rolls and the process of developing the photographs, the costs in the field of materials to produce beautiful images are considerably reduced.
immediacy
The ability to take photos and have them available immediately is one of the greatest advantages of digital photography. In addition, since it allows you to view the result of the image at once, errors can be corrected without incurring in reprocessing.
Storage
A digital card can store many more photos than the original 48-photo roll.
technical advantages
Digital cameras provide the photographer with technical information in real time such as the RGB and ISO values of the image and the histogram, which contributes to the quality of the images.
Disadvantages
Resolution
A common 35mm film had the equivalent of a resolution of 87 megapixels, which is an unattainable value for a digital camera that usually has a resolution of 45 megapixels.
cost of cameras
Due to the technologies that they incorporate and that cameras are now practically small computers, the prices of a good camera or even a mobile phone with a great camera are very high.
electronic noise
The constant electrical flow inside a camera generates a “noise” or image artifact that affects the quality of photographs and is more noticeable when using low ISO values.
types of digital cameras
If all this information has made you want to buy a good camera and try your luck as an amateur photographer, then we will show you what types of cameras are on the market so that you can choose the one that best suits your needs.
compact cameras
These cameras are the basic model of digital photography , they are small, light and limited. The lens is fixed, so you can’t change it, and they have a very small sensor that limits the quality of the photos. They only offer the option of using them automatically, but the most advanced ones offer the option of recording video or connecting to the internet. These types of cameras have been equaled or surpassed by smartphone cameras .
bridge cameras
These cameras are the bridge model between compact and SLR, hence their name. Its lens is not interchangeable, but it offers higher quality than compact cameras. The shutter speed and focus is higher, so they offer faster capture and image quality.
reflex cameras
This is the type of camera best known for its level of quality . They allow you to exchange different fixed and zoom lenses, they can shoot in RAW format and they have many functionalities. Its shape allows it to fit the hands and the buttons are strategically placed. They also offer a large number of accessories and photographic equipment.
CSC cameras
They are a mix of compact and SLR camera . Its size is reduced because it does not have a mirror or pentaprism, but it allows you to exchange objectives. They have a digital viewfinder, consume more battery and have less autonomy than SLRs.

Tips to improve your digital photos
What is promised is debt, you already have the basic information about what digital photography is, now we are going to give you some tips that will help you improve your photos and obtain beautiful memories that will last a lifetime. Dare to put them into practice!
know your device
The first step to take advantage of your camera is to know all the possibilities and functions that it can offer you. Explore the features of your device and rehearse how to use them in the best way.
cleanliness is key
Keeping your camera lens clean seems like a no-brainer, but it can sometimes be overlooked and compromise the quality of your images. For cleaning use the appropriate materials, do not clean your lenses with anything you have at hand.
Use natural light whenever possible
Photography is possible thanks to light , hence this is the most important aspect and the one that will condition the result obtained the most. Taking this into account, it is best to work with natural light whenever possible, even if you are not outside, for this you can take advantage of the light that enters a room through a window and achieve soft shadows that give a harmonic result.
take care of the composition
Composition is another key aspect of a good photo, and using the grid provided by some cameras makes it easier to adjust the scene. For example, when taking a landscape photo a tilted horizon can spoil a beautiful photo, so having a guide is important.
Explore the use of perspective
The frontal planes are fine, but in many cases they are boring. Rehearsing with perspective is a very interesting resource when taking photographs because it brings dynamism and gives a sense of depth.
Take many photos of the same scene
It is very difficult for you to get the perfect photo on the first try , so it is best to take several photos of the moment, landscape or person you want to capture, exploring different options until you find the one you like best.
