Dilemma Between SLR and Compact Camera Part Two
0Unique features of SLR cameras (Sequel of SLR and Compact Camera Part One)
As mentioned above, the SLR is intended for advanced users. Include some useful features of digital SLR can help you make the final decision.
* The SLR provides superior performance, especially for shooting in low light because the light sensor (CCD) is larger than compact cameras.
* Unlike compact cameras, the photographer complete control over all settings. So it is the photographer who decides how the image should be.
* The SLR cameras are able to photograph any subject using interchangeable lenses.
* The focusing mechanism of the SLR is very accurate and fast. There will be no shutter lag.
* The SLR can capture images in RAW format, providing more control over how the final image will be generated.

Unique features of compact cameras
While digital SLR cameras are good in some areas, compact cameras have their own unique features.
* You can not record video with the SLR and nothing but this function is compact devices favorites of many people.
* The compact devices are easy to use for normal users because they do not have many settings useless for non-professionals.
* Large LCD preview screen of the compact and lightweight to help people take pictures with little effort.
Choose
If you’re serious about buying a new camera, you should take a moment to analyze your needs and options available. You may be able to seek help from friends who have knowledge in this area or from expert to get a better idea of the products.
If your needs are not covered by a compact camera, you should decide for SLR numérique.Préparez you to spend extra money for additional equipment as necessary goals and other equipment. This will cost a few hundred euros extra depending on your needs.
If your photo needs are normal and it does not bother you to manage some problems such as shutter lag and want to take advantage of greater portability and flexibility, then you should opt for a compact digital camera.
Dilemma Between SLR and Compact Camera Part One
1Many photographers are confused when it comes to know what camera to buy. They find it difficult to choose between a digital SLR and a compact digital camera. Both have their advantages and disadvantages, they should be understood and taken into consideration before making the decision.

The digital industry has made great strides in recent years and falling prices made them affordable SLR cameras for all audiences. Read on to learn the important functions of each and make a choice knowingly.
Shoulder or pocket …
One of the biggest advantages of compact cameras and their compact size and low weight, making them more easily transportable or you hate it. The SLR cameras are larger and often require their own carrying bag. The fact that most SLR objectives are heavier than the camera itself implies that it takes a carry bag for all apparatus of the SLR.
The goal is important but …
Generally, all SLR housings are supplied with a standard zoom lens for normal photos. For example, a 18-55mm lens supplied with the Nikon D40 can make good portraits and landscape pictures. However, you will need to purchase additional targets for specific shots. For example, the 18-55mm is not enough to take a closeup of a bird on a branch of a tree near you.
On the other hand, a compact has a zoom range greater compared with standard lens supplied with a SLR. These objectives are powerful enough to meet the normal photographic needs, such as taking family portraits and photos of the picnic. Most manufacturers use high-quality lenses for their compact cameras, the image quality is generally good.
Import duties
With digital SLR cameras, you do not need to place the subject in the center of the frame to the point.Vous just have to focus a point and support to the shutter release halfway. The point will be in a split second.
With compact cameras, you need to place the subject in the center of the frame and press the shutter release halfway to the point. You can not release the button until you have not finished the framing and fired.
These are significant differences between the performance of autofocus SLR and a compact.
* The digital SLR offers a focus and a sharper dose compared to a compact.
* Unlike the compact autofocus, the LRT is very fast. Take stock with a compact can take one to two seconds.
* In the digital SLR, there is no shutter lag, the delay between pressing the shutter and taking the photo is very short. In the compact camera, the shutter lag and relatively large – a shift from one to deues seconds is common.

Other checkpoints
Sensitivity determines the relative aperture and shutter speed for a given illumination and is measured in ISO. The user can choose between different values, 100, 200, 400, 800 and until 1600 in most cases. Some devices allow you to go towards larger sensitivities (3200 and even 6400!) For shooting in dark environments. But beware, the quality is rarely optimal, high sensitivities are highly-generating “noise” that is to say of parasites that affect the rendering. In photography, there was talk of “grain” to describe this phenomenon.
Flash: Fill flash can also be helpful. Admittedly, in addition to other accessories (and more so, optics and the essential carry bag, which is also a budget between 20 and 300 euros depending on the size and quality). But it will replace the flash, generally less efficient (power, uniformity).
Burst Mode: To take photos of moving subjects, at sporting events such as photographing multiple images to the queue automatically multiplies the chances of succeeding in the picture. Burst mode is measured in frames per second, it is generally around 2 or 3. Some devices offer more, up to 8 frames per second, but the resolution of each image is greatly reduced.
RAW: photographers will appreciate also save images in RAW format, a possibility not systematic. This is a crude recording format. The image, untouched by any treatment, can then be worked (white balance, exposure …) on a computer using editing software. Then stored in a readable format (in. Jpg for example) for the operation. This method offers greater flexibility in changing parameters shooting look better, and the ability to save the settings chosen (on the computer) to apply to multiple images (batch processing). Consideration: RAW files are very large, which necessitates the use of large capacity memory cards.
Type of power (batteries or batteries): SLR cameras are powered by lithium-ion batteries. Their autonomy can take 250 pictures to a minimum. A second copy of batteries, to take charge, can be very handy to not run out. Have between 30 and 85 euros (depending on the brand and model) for a battery.
Optical illusion
The shadow still hangs over the film in digital photography. Indeed, the objectives that equipped the silver boxes can be used on digital if they are compatible (check when you buy the digital box). The transaction will result in contrast to a loss of field. The reason? The digital sensor is smaller for the film of silver (15 × 23 mm × 36 mm against 24). Direct result: only the central portion of the image is exploited and should be applied to the objective a correction factor of about 1.5 for the corresponding focal length. A target of 200 mm film frame as a 300 mm when mounted on a digital camera. That’s why manufacturers give the focal lengths and their ‘equivalent 24 × 36.
Aim for the SLR!
Only reflex viewfinder is equipped with a “TTL” (Through The Lens “or” TTL “), also known as, suddenly, under” reflex. ” Very reliable, it faithfully reproduces the recorded image, which is why photographers love it.
Initially, the LCD of a DSLR just used to view stored photos. But now, on some models, it can target. It is the function “live view”. Practical use when the viewfinder is complicated (for shooting at arm’s length in a cramped, for example), but it often suffers from a flaw that repels photographers: the inability to control the focus (as it takes to trigger the shot).
SLR Digital Cameras At a Glance Part One
0The SLR is the most advanced digital cameras, but also the most expensive. Seasoned professionals and enthusiasts are turning to this high-end equipment to satisfy their need for total control of camera settings.
The SLR is a digital camera designed not just to take pictures, but to make photography a hobby (or profession) as such. On this type of device, the manual settings (aperture, shutter speed, sensitivity, white balance, focus, etc..) Play for much of the rendering quality. Therefore the master to perfection to take full advantage of his aircraft. Here is a small developed to guide you if you decided to take the plunge. And thus join the world of photography enthusiasts.

The sensor, an essential component
As with any digital camera (compact, bridge), the sensor resolution is among the first criteria set forth by the manufacturers. It is however more important: the average for an SLR is now around 10 megapixels, which is already huge. To obtain a quality image for printing, the density of the pixels must be 300 dpi (or dots per inch) minimum. A 10 × 15 image therefore requires 2.10 million pixels (megapixels), a 6-megapixel sensor lets you print an image of 18 × 24 cm. A higher resolution is only useful for bigger enlargements, or to crop the image from his computer.
On an SLR, this component is very costly to produce on average four times larger than a compact, more so than on a bridge. The most common format is called APS-C, which equates to approximately 15 × 23 mm. Only high-end devices are equipped with sensors larger dimensions “historic” 24 × 36 mm. We are talking about sensors “full frame” (FF). If the format of the sensor is not really a factor of choice (APS-C largely dominating the others), it should however be taken into account if the child of the film, you already have your goals (see box).
Budget: he tick on optics
Like their ancestors silver, the objectives are interchangeable digital SLR. This is one of the advantages of these devices, but also where lies their main weakness: sensitivity to dust. When changing the lens, the sensor is exposed. Any dust that settles there appears on the pictures! Manipulation must be done in a clean environment. Some models incorporate a function to clean the sensor when switching off.
It is commercially sold in boxes only, or with a basic objective of very average quality (even by major manufacturers). Immediately opt for a better goal might be appropriate, even if it costs more. Much to be aware, optics anyway represent a significant budget for any SLR user. To cover the same focal range as a bridge, for example, will buy two or three goals at least! The supply is abundant. Ultra-wide angle to telephoto to photograph large areas or microscopic insects found on the market a variety of fixed targets or with focal ranges varied. Their prices range between 100 and … 9000 euros! The choice will be primarily guided by the needs and requirements of the photographer.
Stabilization: case or objective?
This rate, which may seem exorbitant (the equivalent of ten best washing machines), we have seen for a Canon professional displays … 5.37 kg on the scale. The weight of an optical, extreme in this case, is very variable. The weight of a body only vary as much, from 350 grams to 1 kg. Unless you use a tripod, and whatever the weight of the whole, difficult to stay perfectly still during the shooting. To compensate for the movements of the photographer, and thus avoid the pictures are blurry, manufacturers have integrated stabilization systems. Two schools of thought, each making his choice. Canon and Nikon have chosen to stabilize their goals, other brands (Olympus, Pentax, etc..) Opting for a stabilization of the housing itself (its sensor, more precisely). The former believe that every goal must be stabilized according to its intrinsic parameters (focal length, weight). The latter, which allows the stabilization of the housing cost savings (a stabilized lens costs an average 25% more expensive).
How to Clean DSLR Sensor
0If there is a downside to digital, it is this: the dust and particles on the sensor make life very difficult by increasing either the time of editing or cleaning costs and loss of the device to some time. You’ve thought of doing it yourself, but the threat of large companies ignore the warranty if something happens. What to do?

Prevention is paramount. Never leave the room air. It is better to change the lens quickly or put the cap to prevent dust from entering. Also, always turn off the camera before changing lenses, static electricity attracts dust on the sensor. In addition, before installing your lens, a little bit pear-air in the room and on the basis of the lens does not hurt.
However, the dust still finds its way. We cannot avoid cleaning the sensor but only delay it, even with the new gadgets (self-cleaning sensor Canon Rebel XTi). So here are some tips:
Cleaning house
All manufacturers of digital SLR cameras do not recommend this approach on pain of not ensuring your equipment if you damage the sensor, but with minimal detail and the right tools, it is impossible to happen.
First, a clean working environment is required. Next, make sure your batteries are fully charged. Arrange the following tools handy: – pear air (gas bomb: no question !!!)- aspiring Green Clean system or other (optional) – liquid Eclipse (very volatile, leaves no trace)
- Cotton swab (VisibleDust offers excellent products for all sensor sizes and you guarantee that their products will not damage your sensor)
Procedure:
1. Open the case.
2. Blow a hit with the horn area.
3. Make up mirror.
4. Blow with the pear and vacuum the particles with your system, or blow with the camera facing down so that the particles not fall on the sensor.
5. Take a cotton swab and apply two or three drops of liquid Eclipse.
6. Take one or two passes over the sensor.
7. Repeat step 4.
8. Turn off your camera to
9. Close the box and put a lens.
10. Check results
Now, after reading this, you’ll realize that all these tools are worth a small fortune and I’ve saved the brush to static electricity! Basically, a complete cleaning can be worth between 200 and $ 300 and yet, do not forget to come back as the consumable liquid and stems or papers.
Me, I go to a service center not too far that I do it in 10-15 minutes for twenty dollars (Pro Camera Service). So I strongly advise you to search your area to find a service center! At $ 20 4-6 months, it takes several years before reaching the price of a complete kit!
