First, you need to understand all these basic things
Understand the camera
Holding the position of your camera
Our King: ISO
Our Queen: shutter speed
Our Princess: aperture
Combo combination of these three – exposure triangle
Understand all modes
Manual focus matters
A right tripod
Capture off flash
Here in detail
So that’s the basic beginner step you must have to do before capturing images with your DSLR, why!!?? because if you don’t know the basic functions of your DSLR or working of your DSLR than how could you capture better photographs.
yeah!! I know it sounds boring, but believe me, all the time this manual takes it’s actually worth it. I am not telling you to remember every feature, functions which are available in that manual, just read the manual carefully. Because of that, you may learn a lot more new things and also able to understand your DSLR more right way. So the basic step is clear, now you are able to make a good connection with your new DSLR.
Understand your DSLR camera
That’s the second and very important part to make a huge improvement in your photographs. Now you know how all the features and modes are working if you don’t know then don’t worry we’ll discuss them later in this article. In this part just understand the basic features given in your DSLR camera. Features like buttons.menu or all the stuff available into that 3 inches LED screen.
Holding position of your DSLR camera
One of you ask me, is the shape of your DSLR matters? And my answer is yes it matters. Find some best grips to hold your DSLR camera because if your grip on your DSLR is better than you don’t need a tripod anymore to capture some normal shots. So the holding position of your DSLR matters a lot. Just think, If your hands are not so steady then you cant able to capture more sharp images. Make it clear with your camera that “you hold the right position by analyzing the object”. No matter if you are doing landscape, portrait or any other types of photography.If you don’t have any control over your holding position of your DSLR then you’ll never get a better result,or to get better result you must need a tripod.
Our King: ISO
What is ISO ? and Why we need ISO?
So ISO is a feature we use to manage the light which reflects your DSLR camera’s sensor while you are capturing an image. Let me make you more clear, assume that you are doing indoor photography, to make your model lighter you use any flashlight. And if the light is too high then you’ll defiantly get a very brighter photograph. If the light is too low then you’ll get darker images.
So to make the connection between your DSLR camera’s sensor and outside light we must need to understand ISO.
There are two different rang of ISO.
2.High ISO(range:800-6400 or more)
That depends on the environment to use Low or High ISO, but ISO 800 is best to capture in any situation. So you don’t need to change if you want to just click images.
What is Low ISO Range?
As we know the range of Low ISO is between 100-800. If you got something really bright content or object then you must need to use the LOW ISO number. If you use ISO 100 then you’ll get the darker results then ISO 200 to ISO 6400. So understand this only if the object is more bright or you use more flashlight then just make your ISO low. If you get darker images then just simply increase your ISO to get brighter images.
Best time to use low ISO numbers
If you are shooting outdoor, like doing a photo shoot when the sun is high or some landscape photography, then you must need to use low ISO numbers in short, if your outdoor environment is bright then you must need to use low ISO numbers.
How does a DSLR work?
So what makes the difference between DSLR and SLR.? Let’s look at it: SLR camera has a lens attached (changeable) which is focused directly on the film (camera roll). A major component of the whole SLR setup is that Lens and Film are separated by a Mirror. As the name says single-lens reflex, when you hit the shutter or say click, in short, mirror raises up and allows the light to reach the film.
So for DSLR..its Digital SLR where the only thing that is changed instead of actual roll film, you have a CMOS sensor that actual capture image in a pixel format. SLR camera uses a film made of plastic, gelatin, and other material to record the image – a DSLR captures the image digitally, on a memory card. CCD and CMOS sensor:
Now let’s look at the working of the sensor:
CCD and CMOS sensor:
Both CCD (charge-coupled device) and CMOS (complementary metal-oxide-semiconductor) image sensors start at the same point — they have to convert light into electrons(electric signal). One simplified way to think about the sensor used in a digital camera (or camcorders) is to think of it as having a 2-D array of thousands or millions of tiny solar cells, each of which transforms the lights from one small portion of the image into electrons.
Most digital cameras use a CMOS sensor, because CMOS sensors perform better than CCDs, offering faster speeds with lower power consumption. CMOS sensors incorporate an integrated circuit, helping reduce costs. CCD is still in use for cheap low entry cameras, but weak in burst mode. Both types of sensors accomplish the same task of capturing light and converting it into electrical signals. The next step is to read the value (accumulated charge) of each cell in the image.
Each cell of a CCD image sensor is an analog device. When light strikes the chip it is held as a small electrical charge in each photosensor. The charges in the line of pixels nearest to the (one or more) output amplifiers are amplified and output, then each line of pixels shifts its charges one line closer to the amplifier(s), filling the empty line closest to the amplifiers(s). This process is then repeated until all the lines of pixels have had their charge amplified and output. An analog-to-digital converter turns each pixel’s value into a digital value.
A CMOS image sensor has an amplifier for each pixel compared to the few amplifiers of a CCD. This results in less area for the capture of photons than a CCD.in most CMOS devices, there are several transistors at each pixel that amplify and move the charge using more traditional wires. The CMOS approach is more flexible because each pixel can be read individually.
CCD use a special manufacturing process to create the ability to transport charge across the chip without distortion. This process leads to very high-quality sensors in terms of fidelity and light sensitivity.
How DSLR Cameras Work
When you look through a DSLR viewfinder/eyepiece on the back of the camera, whatever you see is passed through the lens attached to the camera, which means that you could be looking at exactly what you are going to capture. Light from the scene you are attempting to capture passes through the lens into a reflex mirror (#2) that sits at a 45-degree angle inside the camera chamber, which then forwards the light vertically to an optical element called a “pentaprism” (#7). The pentaprism then converts the vertical light to horizontal by redirecting the light through two separate mirrors, right into the viewfinder (#8).
When you take a picture, the reflex mirror (#2) swings upwards, blocking the vertical pathway and letting the light directly through. Then, the shutter (#3) opens up and the light reaches the image sensor (#4). The shutter (#3) remains open for as long as needed for the image sensor (#4) to record the image, then the shutter (#3) closes and the reflex mirror (#2) drops back to the 45-degree angle to continue redirecting the light into the viewfinder.
Obviously, the process doesn’t stop there. Next, a lot of complicated image processing happens on the camera. The camera processor takes the information from the image sensor, converts it into an appropriate format, then writes it into a memory card. The whole process takes very little time and some professional DSLRs can do this 11+ times in one second.
Now the word pentaprism seems confusing so let us know about it:
Instead, the two faces are coated to provide mirror surfaces. The two opposite transmitting faces are often coated with an anti-reflection coating (is a type of optical coating applied to the surface of lenses and other optical elements to reduce reflection.)to reduce spurious reflections. The fifth face of the prism is not used optically but truncates what would otherwise be an awkward angle joining the two mirrored faces.
