Most Commonly Asked Questions about Cameras?

What are two main types of Cameras?

Camera users rely on the camera’s viewfinder to help them frame and focus their shots. But there are two types of cameras available today, DSLR (Digital Single Lens Reflex) and SLR (Single Lens Reflex). DSLRs offer more features than SLRs, but some photographers find that they’re bulky, slow, and hard to use.

What is an SLR?

An SLR or single-lens reflex camera has a mirror inside its body that reflects the scene coming through the lens up into the viewfinder. When you look through the viewfinder, what you see is what will be captured by the camera’s sensor.

How a digital camera work?

Each time you press the shutter release button, a simple mechanism allows you to see exactly what your camera lens sees. The view through the viewfinder of an SLR is more like looking through binoculars or a telescope than it is looking through a regular camera. You can easily change the focus using your fingers instead of having to bother about moving any dials on your DSLR. When you’re ready to take the shot, all you have to do is press the shutter button down halfway to “focus lock” and then press it all the way down when everything is in sharp focus. SLRs don’t have live preview capability, but they are faster because there are no focusing delays associated with DSLRs.

What are the pros and cons of DSLR and SLR cameras?

Pros of both types include faster image capture, very high Quality of Image (QOI), great features & flexibility, size & weight options that suit everyone’s needs, affordable price range compared to medium format digital cameras like the Dalsa Cybershot or Bronica Zenzanon, quick data downloading times (especially with larger file sizes), and the availability of a wide variety of accessories.
Cons include camera shake or blurry shots due to hand-held use, grainy/noise issues if you don’t have a good lens, slow autofocus time when using flash, slower shutter speeds for shooting in low lighting conditions outdoors, extra expense if you have to buy film for your SLR exposure meter, and the fact that there is no live preview mode on your camera.
The critical difference between an SLR and a DSLR is that an SLR has a mirror inside the body of the camera while a DSLR does not. This means that images from an SLR are seen through a viewfinder rather than the actual subject being photographed. When it comes to image capture, the SLR is faster than a DSLR because there are no focusing delays associated with DSLRs. DSLRs do not have live preview capability, so you need to look at your LCD screen for this information too.
To choose between an SLR and DSLR, ask yourself what the primary purpose of the camera will be as well as how often you’ll use it. If you want a serious camera that has a large storage capacity and can take several shots without reloading, then an SLR is worth considering over a DSLR because an SLR can shoot up to 24 frames using one roll of 36-exposure film while a DSLR could only take 2-3 shots before reloading is required. If you are into photography purely for a hobby or the occasional get-together with friends, then a DSLR is better since it will serve your needs more than an SLR. The two most significant factors to consider when choosing between an SLR and DSLR are convenience versus quality.

SLRs are bulky because they use mirrors inside the body of the camera. This makes them slower than DSLRs, but their bulk actually helps stabilize the camera better when it comes to reducing blurriness caused by handshake or movement of people in your scene. When using an SLR, you can easily focus on objects relatively far away without having to change any settings on your camera. The disadvantage here is that you cannot achieve macro shots with an SLR.
SLRs are slower than DSLRs because the mirror inside the camera has to rise up and down for each shot you take. The viewfinder, however, does not use extra battery power, so you won’t have to worry about your camera dying on you just because it is using a viewfinder rather than a live preview screen.

What gear you need to take great photos?

DSLRs or Digital Single Lens Reflex cameras have been popular for decades because of their size and portability. Today’s models, however, are also known for producing high-quality images that can rival those taken by 35mm cameras. They are no longer just ideal for professional photographers but are being recognized as good options for amateurs too. Although there are some excellent point & shoot compact digital cameras out in the market today, for those who appreciate superior image quality and control over your photography, DSLRs are the way to go.

What gear you need to take great videos?

When you think of video, digital cameras may not be the first thing that comes to mind. But if you want to take high-resolution videos on professional-grade camcorders, you will definitely need a camera with a fast frame rate. If you have considered video as one of the main features of your next camera, then why not use an alternative that combines both pictures & video capture? DSLR cameras offer just this advantage – they also take great-looking pictures!
If there is anything lacking in DSLRs, it’s their LCD screens which are relatively small for viewing or composing shots. Manufacturers know this is a weakness too, which is why almost all DSLR manufacturers have chosen to include screens that can be rotated at various degrees for more flexibility.

Why a DSLR is best to use?

Let’s face it – you are not always able to see clearly through your camera’s viewfinder. When you are using a DSLR, it compensates because the mirror inside an SLR reflects light coming directly from the lens toward the viewfinder. However, when you take pictures, this mirror flips up so that light can go straight through to make images come out sharply in your photos. This is one of the reasons why digital photography has become popular even among amateur enthusiasts – because no matter what lighting conditions you are in, DSLRs improve your ability to capture clear, crisp images.

Why it’s better to go with a DSLR?

The image sensors in SLRs and most digital cameras are similar, with the latter measuring approximately 17mm x 13mm; cameras that use film have a larger 24mm x 36mm sensor. What sets DSLRs apart is that they do not need to use a separate device, like an optical viewfinder or LCD screen, to help you aim your camera at subjects when taking pictures. This allows DSLRs to showcase more accurate colors and gives you greater control over your photography.
When using point & shoot or compact digital cameras, you usually look through an optical viewfinder, but this is not the case for DSLRs because their primary viewing method relies on an electronic one. Although many DSLRs have an option for changing or adjusting the viewfinder’s brightness level, you will find that the LCD screens are not as friendly when it comes to taking pictures outdoors during daylight hours.
For example, if you are using a DSLR with its electronic viewfinder, there is no glare, unlike viewing through an optical viewfinder or even on most compact digital cameras’ LCD screens. This helps ensure your vision is not impaired when framing shots. Electronic viewfinders are also excellent because they let you preview photos in real-time before actually taking them. This means that if there are any problems with your shot (e.g., over-exposure), then you can immediately take another one instead of missing what could be a once-in-a-lifetime opportunity.

Why DSLRs are better then compact digital cameras?

One of the main reasons why amateurs and even expert photographers use DSLRs is because of their ability to capture images at various ISO levels. Not only does this ensure that your shots are evident no matter what lighting conditions you are using, but low-light shooting is also enhanced thanks to faster shutter speeds, plus there is typically less noise (graininess) in pictures taken with high ISO levels. Compact digital cameras do not come with interchangeable lenses like DSLRs; thus, they tend to have smaller sensors that produce lower quality photos even when used outdoors on sunny days. They also do not support interchangeable lenses, which means the zoom feature of cameras will not be as effective, and you will need to be closer to your subject than with a DSLR. However, this also means that the lenses of compact digital cameras are smaller and more lightweight – which can be an advantage if portability is what you’re looking for.

Why compact digital cameras re not best for videos?

The lenses of most DSLRs do not protrude when taking pictures like the ones on compacts (at least not by much), and they also come with wider maximum apertures. This means that even in low-light conditions, DSLRs produce brighter images because their larger sensors capture more light while faster shutter speeds help reduce the amount of noise (graininess) added to photos. Compact digital cameras, however, have a much harder time producing photos in low-light settings. DSLRs also come with various video modes that allow you to record action or important events without compromising quality. These advantages are not available on most compact digital cameras.

WHY COMPACT DIGITAL CAMERAS ARE NOT BEST FOR PORTRAITS?

Many of the lenses used for DSLRs have large maximum apertures. This makes them great for portraits because it is easier to separate your subject from the background by blurring out (aka bokeh effect) the latter – which can make for beautiful and professional-looking photos. Compact digital cameras only come with smaller aperture lenses, and this limits their ability to blur (out) backgrounds and create sharp images.

WHY COMPACT DIGITAL CAMERAS ARE NOT BEST FOR ACTION SHOTS?

Thanks to their large sensors and various modes for stills and video, DSLRs are great for capturing fast-moving action such as sports or wildlife. If you’re using a compact digital camera instead of a DSLR, your photos will be blurred because it is not easy to hold them steady. Not only that, but autofocus on compact cameras tends to be inaccurate when taking pictures of moving subjects – which is why many photographers rely on manual focus. However, this also means that the battery life of compacts can suffer because most models must use an electronic viewfinder instead of an LCD screen. And with the exception of new mirrorless interchangeable lens cameras, the viewfinder of compacts do not show previews of photos in real-time.

WHY DSLRS ARE BETTER FOR TRAVEL?

DSLR cameras are also known for their ability to work great even when paired with long telephoto lenses (also called superzoom) – which is why they’re a favorite among wildlife photographers and photojournalists. Telephoto lenses compress scenes, bringing distant objects closer together without distorting them in any way. Your shots will be more professional-looking thanks to these capabilities. Most compact digital cameras have a hard time working at total zoom distances – especially if you try shooting at night or indoors because of smaller sensors and slow autofocus tracking performance. With the exception of newer mirrorless interchangeable lens models, compact cameras do not have a hot shoe port. So if you want to add external flash or other accessories such as rangefinders and time-lapse gadgets, you will need to mount them on the tripod socket.
