Understanding the basics: Professional cameras comprise of several different components including your camera body, the lens and external accessories. All these components together enhance the quality of the image. Professional grade DSLR’s (Digital Single Lens Reflex) normally have 16 mega pixel sensors, offering full frame capture. Full frame CMOS (Complementary Metal Oxide Semiconductor) sensors allow you to capture images in the best possible resolution, which also determines the size of the image. Shutter Speed, Aperture and ISO: The three main elements which determine the duration for which the sensor is exposed, brightness and exposure levels and what is the light sensitivity of the image. In short, the shutter speed controls the time for which the shutter remains open to capture an image. Fast moving objects require a higher shutter speed when compared to taking stills. The aperture controls the amount of light which enters through the lens, ultimately determining the exposure levels of the picture taken. An over or underexposed image is the result of improper aperture settings. ISO determines the light sensitivity levels of the sensor, some areas in the image may be subject to higher exposure levels which make them brighter compared to the rest of the image.

The technology in today’s world is much more evolved than it was in the 90’s. Science and technology has given us a lot of room for advancement, and its applications has never ceased to mesmerize us. Communication has been made so easy and convenient. In any given phone, all the basic functionalities which needed separate equipment to run them before has now been implemented in one small mobile phone. These include a plethora of features such as FM, camera, video recording, calculator, alarm and so on. However, whatever may be the quality of the excellent camera that your phone might have, we somehow still prefer to have a separate camera and camcorder for clicking a picture or recording a special event. Even with the advent of cell phones and camera technologies in cell phones, the market for cameras and camcorders are still hot in the business. The deals on these gadgets are even hotter! Many prestigious brands in the industry have marked their presence by staying updated with technology and its requirement. Hence, they have been able to still survive as customers’ favorites. Many other companies who started off with similar products did not last too long in the market for various reasons.

The oldest known photograph was taken back in 1826 on a block of Bitumen of Judea, by Nicephore Niepce. The photo was taken using a pinhole camera, which was Nicephore Niepce’s own make on a sheet of paper coated with silver chloride. Unfortunately, there was no knowledge about the removal of the unconverted silver chloride or of fixing the converted silver chloride. The photograph thus could not be preserved. Origins The two critical principles of camera and photography were known long back in history in camera obscura, literally meaning a darkened chamber, and that certain compounds reacted to light. There is no evidence of any one having tried to combine these two principles to produce a camera image till 1800, when Thomas Wedgwood made an attempt albeit unsuccessful. Ever since then, the fate of camera and photography are inseparably intertwined to this day. It is worth remembering that Aristotle had described a contraption that became the first ever camera. The principle camera obscura finds mention as far back as circa 470 to circa 391 by the Chinese Han philosopher Mozi. He even stated that the image is inverted and this due to light travelling in a straight line. In the 11th century, an Arab physicist Ibn al Hayatham had written a very influential book on optics.

Have you considered investing in a GoPro camera? If so, you need to understand that just paying for the latest model is not the right way of knowing which one suits your needs. There are a plethora of GoPro cameras in the market, and each of them sports a unique, state-of-the-art spec sheet. So here’s our list of four unique GoPro cameras for you to pick from to suit your requirements. Hero9 Black As of 2021, the GoPro Hero9 Black is one of the latest designs from its makers. The 2.27-inch rear display makes this model bigger than the Hero8 Black. The camera can record amazing video in 5K up to 30 fps and the best-in-class image stabilization system. The camera also features a front-facing color LCD screen which is perfect for those looking to frame themselves while vlogging and even taking selfies. Hero8 Black We agree that the GoPro Hero8 Black is an older model, but it still is a value-for-money action camera. You can record 4K footage up to 60 fps as well as take surreal photos at 12MP. This GoPro also has an in-built mount that makes attaching accessories a whole lot easier. Also, just like the Hero9 Black, the 8 is designed to latch on with Media, Display, and Light Mods, all of which enhance user experience.

Currently, there are three models lined up by GoPro, these are GoPro Hero7 Silver, Hero7 Black, and Hero7 White. GoPro stopped selling the other cameras that were previously lined up after these new cameras were launched back in September 2018. However, you can find these old cameras on other websites that sell but officially the manufacturing has been stopped. This ensures that with the launch of the new models, you can also purchase the old ones at some decent prices. GoPro Hero 7 Black The frame-rates and resolutions tend to be similar to that of the previous 6 series. However, GoPro has aimed to improve their camera in other aspects. The HyperSmooth is a great addition to the new GoPro Hero 7 Black. The camera enhances the form of image stabilization that can be used in multiple shooting modes. Running at 60 frames per second, the smoothest picture possible is provided by GoPro. As compared to the older models, the audio commands also happen to be more responsive. With the help of SuperPhoto tech, automatic improvements on noise reduction and lighting colors are observed across multiple frames. Also, the pro tune feature gives the option to take the safety wheels off and tweak the setting according to your own personal style.
