<h2 style=Manual modes and what they mean

The vocabulary of digital photography can be incredibly difficult if you are not familiar with it, but the good news is that it is not difficult to master. In addition we speak here of smartphone is the list of vocabulary is therefore slightly shorter than that of real digital cameras. I chose to use the S3 here for my demonstration because it is one of the most popular devices but the leon works with all devices


Resolution is the first thing we need to clear up. The higher the number of mgapixels in your camera, the more you can capture mgapixels. The number of mgapixels is for the camera sensor, where image capture occurs (like film in traditional photography). A pixel is a single point of color, multiply it by a million and you have a mgapixel. Multiply that by the number of your camera and you have a whole bunch of pixels on the sensor. A higher number does not necessarily mean that the device is better, just that it is able to capture more information. But this is almost never necessary for an amateur photographer. It's like having a Ferrari engine in your lawn mower – it does not help much unless you plan to mow 200 km / h. The S3 has a fully capable 8 MP sensor that does not need unnecessary exaggeration.

The resolution tells you how many pixels the sensor counts and how much the ISO is sensitive to light. / AndroidPIT
<p style=Also make the difference between the number of pixels of a screen and the camera! So what we call Full HD (1920 x 1080 pixels) is almost a 2 MP camera! And a 2 MP photo (1800 x 1200 pixels) can be printed in magazine quality (the equivalent of about 300 pixels per inch on your screen) in 4 x 6 inches – the average size of the photographs. Depending on the size of the screen, the resolution can be lost: if you look at a 13 MP photo on a small screen of a smartphone you will not notice the difference. Similarly, unless you cut a lot of your clichs, taking pictures of 13 MP if you do not print them in hyper big or you will not watch them on a large TV screen, is strictly nothing else than consume storage space. The 8 MP S3 are therefore quite sufficient to produce excellent quality photos printed in 8 x 10 inches or even 8 x 12 inches (A4).

Aperture simply means how much the hole in the lens is open and lets the light through / figcaption>
<h2 style=Opening

The opening is a nice word that means Hole. The aperture of the camera simply refers to the size of the lens hole that lets the light through to reach the sensor. It's easy to understand: the bigger the hole, the more light it lets in; the smaller it is, the less light there is. The opening is measured by a number prcd of the letter f. But just to make life difficult for you, this is the opposite: the smaller the number, the bigger the hole. And vice versa. Fortunately for the owners of S3, the S3 camera has a fixed aperture of f2.6 (which is big enough) so you do not need to worry about changing it, but at least now you know what it means !

You can clearly see how much gain or "noise" you gain or lose by changing the ISO / CNET
<h2 style=ISO

The ISO is pretty simple too: basically, if you have low-light scenes, such as indoors with dyed lights, at night or in dimly lit places like restaurants or bars, you usually need to have more light entering the sensor of your camera to capture an image. The problem is that the more light you become sensitive (to get more on the sensor), the more you'll be sensitive to "noise". The sound is that granular quality that you have probably already express a lot of times. The lower the number of ISOs (for example, when shooting in daylight), the less light sensitive the sensor will be (and therefore the noise), the higher the number, the more noise you will hear. The S3 has an ISO range of 100 800, but 80 1600 in automatic mode (digital SLR cameras can go up to about 6400).

Shutter speed

The shutter speed simply reflects how long the sensor will open the light. Of course, in an S3 there is no control over the shutter speed, it is controlled by the processor that activates the sensor. The higher the shutter speed, the faster the photo will be taken, and therefore less time the light will reach the sensor. It's ideal for sunny days because you do not need too much light but terrible when it's dark. A high shutter speed is also ideal for capturing motion. The S3 handles these sitters very well.

Slow shutter speed (center) and not high enough (right) / Shutter Stoppers

Slow shutter speeds, the opposite, are perfect for when there is less action or if you are facing the light: this means that the sensor is exposed longer light capturing more details. As you can probably guess, the more the sensor is open the more noises, vibrations or fumes can enter your photos. S3 tends to have slow shutter speeds on higher ISOs in low-light situations (in auto mode), which means you'll have more blur but less noise – it's important to know if you have want to get better pictures in low light. But to get the highest ISO 1600, you will not be able to change the shutter speed because you will have to be in automatic mode. You can get really nice effects with a stable camera and slow shutter speeds, such as light tracing, if you know how to set it up. There are many applications that will allow you to do that.

exposure modes
You can set the measurement mode to scan the entire frame or just a part / All Ears Blog

Exhibition Mode

Exposure Mode is a bit like autofocus – it defines what part of the image you want to expose in an optimal way. If your S3 is causing you problems with the exposure (always on or under-expos) the cause could be l and you can change it. Like most digital devices, the S3 has three measurement modes: matrix, central-weight or point. Matrix measurement, in addition to being cool to mention in the evening, allows the camera to give importance to the whole frame: it will value the light from all sources and will try to expose the photo to the best of its possibilities. This is ideal for beginners as it handles complex lighting arrangements. The central lay exposure will prioritize the area in the center of the frame and take a little bit of both ends of the light giving you a balanced result even if the focus is on the central area. Spot exposure will focus on rendering information of a very small area that you can choose.

Once again, it is quite explicit, the white balance is simply the way in which to learn to the smartphone "to see" a pure white according to the luminosity. Obviously for our eyes it is easier to see an object always white whether you are in the sun or in the noi or inside. But a device needs your help to re-balance and make natural colors (based on white). If you still have pictures that are too pink, too orange or dyed, now you know why. Fortunately, smartphones are delivered with a large number of pre-set white scales (for indoor, outdoor etc.) if the automatic mode is not enough. Test them in different environments to start having the reflex to change them in the future.

Consulting and inter-relations

So what does all this mean? If I have not lost you so far, all you need to know are two things: first, almost all of these options work in relation to each other, so once you've made these relationships everything is fine. Daylight: low ISO / shutter speed high. Night: High ISO / slow shutter speed.

Second: do not be afraid! Instead of spending hours on the Internet trying to learn more about your device, scroll through your camera options and try all of them to see what the differences are. There are also a large number of applications available with other pre-defined shooting modes that allow you to create your own "modes" according to the settings you use often.

overexposed and underexposed
Underexposure: not enough light. Over-exposure: too much light. / Exposure Guide

The best news for those who have a Galaxy S3 is that the aperture is fixed and you can not fix the shutter speed either. Two things less! An opening of F2.6 lets a lot of light enter all the time. This means that your shutter speed will generally be very fast: since a lot of light reaches the sensor it does not need to be open for a long time and this will limit camera shake or motion blur. Likewise, your ISO may remain low because you do not need an ultra-sensitive sensor if there is a lot of light available. So, the larger the aperture (or the higher ISO), the faster the shutter speed can be.

Low brightness

In low light, however, you must change your settings because it is where you will have the most problems. Because the opening of the S3 is fixed, if you have problems taking good pictures in low light you have to change your ISO (you can not change the shutter speed). The higher the ISO value, the faster the shutter speed should be to prevent too much noise from entering your sensor. But because there is not enough light available, you run the risk of adding camera shake, especially if you hold the camera vertically (it will move when you press the shutter button). Because of the small number of settings of the S3, it is mainly in this area that it will be difficult to take good pictures. But you can do a few things: use the punctual exposure to illuminate the focus area before taking the picture so that the S3 knows o beam the focal lens (you'll have to be fast though because the S3 gets refocused fast) or you can make the camera as stable as possible to avoid movements. Just find a stable surface and put your phone on it.

<p style=This is a very general introduction to digital photography beyond the automatic mode of S3 and do not take it as a course. I am certainly not an expert. There are also lots of other pre-defined modes that can help you save multiple settings if you do not want to. Just remember that nothing is Chinese, that everything is li and you can finally understand what they mean by testing some ISO settings for example when you want to take a picture in a bar. And once you get to master your S3, you'll be able to tackle digital reflexes! By the way, did you know that you can enter the S3 camera app just by touching the lock screen and holding your finger down when you rotate the phone to landscape mode? Nice, huh?
