Photography is not a new industry, however, not so long ago, professional cameras were available only to a very limited number of people like movie makers and media because cameras were very expensive for an average person to afford and very big to carry for personal use. So thanks to the huge revolution made by electronics that made it possible for the average person to have a professional camera at a decent price and portable size with the ability to take very high detailed images, switch between different lenses, and have more advanced control over the camera which is a lot more fun and open an endless number of possibilities to capture great images. Therefore, Photography became one of the most interesting hobbies nowadays with lots of fun whether you’re an amateur or looking for a career with a good salary, it also teaches you how to look at your surroundings through a new different creative way.
What Is Photography?
Photography is the art of creating images from the environment around us by capturing the light and colors using cameras.
Photography is all about light and colors, the quality of light, the color of light, the direction of light, and a lot more to learn about light, with cameras, you will be able to capture light, process it, and save it for later use.
When Was Photography Invented?
- 1826 – The first photograph formed by a camera created by Niépce.
- 1888 – The first film-based camera (Kodac) invented by George Eastman.
- 1991 – The first digital camera created by Steve Sasson.
How Does A Camera Work?
The idea behind all cameras including old film cameras is very simple which is capturing the light at a specific moment and saving it on a light-sensitive material. The main difference between old film cameras and digital cameras is the sensor which developed from chemical to digital, and that change made a huge difference in many aspects including performance and the ease of use as many other industries in which digital technology is involved.
1- Ready Mode
2. Shooting Mode
Note: The digital sensor alone is a complicated piece of technology that needs advanced explanations and time in order to completely understand the very low-level details of how exactly it can convert the light into a digital image or a video, also you will need a basic background in electronics and computer theory. However, it’s very interesting to learn these low-level details that can open your mind to many other topics, and there’s no need for a photographer to understand these low-level details.
What Are The Different Types Of Cameras?
Point and Shoot Cameras
Understanding The Exposure Triangle (The Key To The Better Shots)
The exposure triangle consists of three main elements (shutter speed, aperture, and ISO). The choice of these three elements has a significant impact on the look and feel of your pictures. Different settings are needed in different situations based on the desired results. There Are other elements as well but most of them are editable through photo editing softwares. Luckily, most cameras have smart electronics and light meters in them, which with the auto mode the camera will take all the guesswork out of this for you, and hopefully, you’ll get correctly exposed pictures all the time. But to get really creative, you need to take control.
Typically, DSLRs sport larger sensors than bridge cameras; a feature that allows them to be more light sensitive and so help reduce problems associate with image noise at high sensetivity settings, such as those needed for low light photography.
Subject Or Scene Mode
All digital cameras – all that is except the top-end professional DSLRs — have scene or subject modes, accessed via the camera’s mode dial or via an on-screen menu, that will quickly and automatically set the camera to a specific subject, be it a landscape, macro (close up) or portrait. In each case the camera’s settings will be set to those recommended to get the best from the relevant subject and, as such, it takes some of the headaches out of the “what do I set my camera to?” question. Alternatively, using these scene modes provides a fast way for you to ensure controls, such as white balance and ISO sensitivity, are correct for the shot without you having to spend time making manual adjustments that might mean you miss the picture opportunity entirely. But in either case, they’re great for those still getting used to their camera.
AF and Face Detection AF
Today’s digital cameras have advanced autofocusing (AF) systems that can quickly “see” your subject and (hopefully) achieve pin-sharp focus. Typical AF systems provide multiple focus points that can be used together or individually, depending on the subject or your preference. The focus zones used will normally be highlighted in the viewfinder, or on the camera’s LCD screen so that you can check the camera has correctly focused on what you wanted it to. An alternative is to lock the focus zone to a central AF point and use that for everything. Additionally, Face Detection AF is now a common feature on bridge and (usually) consumer-oriented DSLRs, where you can set the focusing system to recognize faces within the scene and prioritize them. Some cameras can be programmed with particular faces, such as close family members which it can recognize and focus upon even in a crowd. Use Face Detection AF to help get your people’s pictures pin sharp.
Shooting In RAW or JPEG?
Shooting RAW + JPEG
If you have a camera with the ability to simultaneously shoot RAW and JPEG images, you have the best of both worlds in terms of image quality. By capturing both each time you press the shutter, you are provided with a JPEG image to use as a quick proof, say, and a RAW file to tinker with later on and editing software if so desired.
Image Size Settings
This setting provides you with a way to adjust the number of pixels you throw at any image you shoot. If you have a 15-megapixel sensor in your camera, you don’t always have to use all of them. Shooting for a web site will not require such high-resolution images as a shoot for large prints, so you might consider dropping the resolution. Having said that there’s a caveat. If you reduce the resolution, you reduce the amount of detail the camera captures, and this is a problem if later on you decide you want to get a larger image printed of a shot. Our policy is simply this: if in doubt always shoot at the highest possible resolution (and quality, or shoot JPEG plus RAW). That way you can always reduce the image size later on PC; a much better tactic, as you’ll still have the full resolution image at hand if needed.
