With too little light, your photo will be too dark. With too much light, it will be too bright. In both cases some details will be lost. You use aperture and shutter speed to achieve the proper exposure , while taking into account some important side-effects you should be aware about. Imagine that you are looking through a small round hole in a fence.
How much of the scene behind the fence will you see and comprehend? I would say it depends on two factors:. Same story happens in a photo camera. I am now probably risking to get a negative evaluation of my physics knowledge, which would unfortunately be quite fair However, although the physical reasons might differ, the conceptual comparison seems to be quite adequate.
When shooting with a photo camera, you let the sensor see the scene through a hole in the lens called aperture.
The larger this hole is, the more light reaches the sensor. Normally the sensor is closed by a curtain called shutter. When shooting, the shutter opens, light reaches the sensor through the aperture hole, and then it closes again.
A beginner's guide to DSLR cameras
The longer the opening lasts, the more light reaches the sensor. This time is called shutter speed. DSLR camera structure. When shooting, your goal is to expose the right amount of light to the camera sensor that's why it is called exposure.
If you provide insufficient amount of light, the photo will be too dark. If you expose too much light, the photo will be too bright. The larger the deviation from the normal exposure is, the more chance you have to hopelessly lose image data. Software post-processing can fix the perceived exposure for example make a dark photo look brighter , but it cannot re-create the image data lost while shooting. For example, a very common landscape photography problem is loosing clouds in a bright sky. When it is overexposed too much light reaches the sensor , the whole sky becomes completely white, and the clouds cannot be distinguished any more.
On the other hand, with underexposure too little light reaches the sensor , shadowed parts of the image lose details, become completely black. Software cannot rescue such details, because they do not exist in the original image. Thus, it is very important to get the exposure right when shooting. But what is "right"? By "right" I mean that the exposure must be such that the maximum number of the scene details is captured by the sensor. Recording the visual information, as much as possible - that's what the camera is for! Then you present these data in the way you like, create the final photograph in Photo Sense see also why software post-processing is necessary.
In fact, the best properly exposed photos often look terribly dull before software post-processing. Fortunately modern photo cameras often provide accurate automatic exposure evaluation. At least with a natural, more or less even lighting, their evaluation is usually great.
In automatic mode, the camera suggests the aperture and shutter speed values to use. They guarantee a good exposure. But are these really the best possible values? Why not to enlarge the aperture hole twice and halve the shutter speed? The amount of light reaching the sensor will be the same, thus it does not make any difference, does it? Both cameras are weather sealed, but the Nikon is significantly lighter, and offers better battery life, rated up to shots from a single battery. As you can see the Nikon D and Canon 7d Mark II both have their pros and cons, so it will ultimately come down to personal preference as to which you prefer.

A full frame sensor is bigger than the APS-C sized sensors used in all the cameras thus far, meaning it captures more light, and therefore works better in low-light situations. This camera also has built-in GPS, which we find essential for keeping track of where all our photos were taken, as well as a weather-sealed body, tilting touchscreen, and a remarkably compact and lightweight design considering the large sensor.
It also offers a burst photography speed of 6. ISO support ranges up to ,, and the full frame sensor is You get a tilting touchscreen, excellent low-light performance, 6.

With that in mind, we wanted to share some tips to help you get the most out of your DSLR camera. Photography is all about composition. Composition is the art of placing your subjects in a way that is visually pleasing to people looking at your image.
Enjoy your EOS!
It is important not only in photography but in most forms of visual art and it is a skill that artists have been practicing for centuries. A well composed photo is a photo where the subject is clear to your viewer, and is one that people will enjoy looking at. There are various techniques that you can use to compose great images, such as the rule of thirds, leading lines, use of color, symmetry, and more. As you might imagine, composition is a lengthy topic, and one that deserves its own post. Which we have written! A common mistake that many people make when transitioning from a smartphone or point-and-shoot camera to a DSLR is believing that the camera will automatically take better photos.
This could not be further from the truth. Whereas a DSLR is capable of taking far superior photos to a smartphone or compact cameras, it is a much more complex piece of equipment and takes more time to learn how to use it properly. If you leave it in auto, you might find that the images you are getting are the same or even worse than those taken with your smartphone!
This is because a smartphone camera has a lot of software that exists to do photography for you. With a smartphone or compact camera set to auto, all you have to do is compose a great shot, and the software will figure out things like exposure, shutter speed, and ISO for you. This may not get you the best photo, but it generally gives you a good photo.
A DSLR, in most cases, is designed to give you more control over these aspects of photography. This means that you will have to learn how to use it to get the most out of it. Nearly every camera will have various guides and videos online that you can search for, and reading these in collaboration with an online photography course will have you handling your camera like a pro in no time.
RAW is an uncompressed file format where all the data that the camera records when it captures an image is saved to the memory card. Instead, you need to open the RAW file in your editing software, apply the changes you want to make, and then save the file in a friendlier format like JPG. This takes a bit of time to master, but will help you get the best results from your images. Adobe software also allows you to sort, label, and organize your images. There are also free online photo editors that can handle RAW files, plus your camera should come with software that will let you edit the files your camera produces.
Some phone apps like Snapseed see our list of favorite travel apps can edit certain types of RAW files on the go as well. But eventually we recommend getting and learning to use a more powerful software like Adobe Lightroom. You can see our guide to photo editing software and apps for a list and comparison of current options so you can decide which is best for you. As with every device, there are some accessories that we think are worth investing in to help with your photography. Like any skill, photography takes time and practice to master.
Photography can also be a fairly complicated skill to fully grasp, as there are multiple elements to consider, from learning how to compose a photo, to understanding how to properly use a camera, through to editing a RAW file. With this in mind, we can definitely recommend that you look at the options you have for improving your skills. These can be as simple as doing a Google search for a specific issue through to more structured learning options like finding a photography book, taking a local photography workshop, or signing up for an online photography course.
