Digital SLR Cameras, are they any good?

Digital SLR is short for single lens reflex, it uses a mechanical mirror system and pentaprism to direct light from the lens to an optical viewfinder on the back of the camera when composing a photo. The mirror swings quickly out of the way when shutter is released allowing light to travel from the lens to the sensor while blacking out the viewfinder momentarily.   All of this happens automatically over a period of milliseconds, with cameras designed to do this 3–10 times per second.  Hence, the name SLR. Professional photographers often prefer these SLRs because they allow an accurate preview of framing close to the moment of exposure and allow the user to choose from many different interchangeable lenses.

One of the major reason SLRs dominate serious photography is because it allows camera to accommodate a very wide range of lens focal lengths. Otherwise, one has to match the angle of view of the “taking” lens with that of the “viewing” lens. That becomes increasingly complex and expensive viewfinder mechanisms to cover a wider range of focal lengths. SLR technology eliminates that since taking and viewing lens are one and the same.

Most SLRs incorporate a “Live View” mode allowing the photographer to use the LCD to compose shots similar to snapshot camera. In many cases, the mirror is locked up while the prism is diverting the image to a small sensor that feeds through to the LCD rather than to the capture sensor.  However, this does degrade performance.

There are different types of digital SLRs.  When most people say “digital SLR”, they typically refer to “Interchangeable-lens Full System Digital SLR”.  What sets them apart from other types is the ability to remove one lens and replace it with another, say, ultra-wide-angle to super-telephoto.  Almost all of the digital SLRs available today are of this type.  In addition to these, there are other types such as, “Fixed-lens Digital SLR” and “SLR-like or SLR-style”.  

Although there are many different vendors for SLRs, top of the line models for the digital SLRs are from Canon, Nikon, Panasonic, Olympus, and Pentax.  If you are in the market for new camera, look into digital SLRs, you will find them exciting!

For instance, the term mega pixel is always referred whenever this gadget is discussed. It will be clearly understood that mega pixels have nothing to do with the grade of photos shot in this camera. It is a factor that enables enlargement of photo prints. If the photographer wants to take out large size printout of the photos, it is necessary to opt for a camera with higher mega pixels.

To obtain a 5 x 7 inch printout, camera needs 2 mega pixels of resolution. But those who are not trained with the technicalities will have wrong conception that the quantity of mega pixels is the factor that determines the grade of photographs. Similarly optical and digital zooms are very often confusing features to many camera shoppers. Even though both these zooms work together, it is optical zoom that contributes towards better display quality. Digital zoom helps in enhanced focusing. The camera with both optical and digital zooms is preferable, but optical zoom is more relevant.

Another significant characteristic in a digital camera is its memory. Inexpensive cameras have built-in memory to store the snaps. But memory cards are more popular which are removable as well as up gradable. In the market there are various types of memory cards available. Compact Flash, Smart Media and Sony Memory Stick are a few among many types of memory cards widely used in this gadget. To understand the significance of the memory card the user should know that in a digital camera with one mega pixel resolution a 16MB memory card will be able to store 40 pictures.

The optical view finders are included in all digital cameras. But LCD screens are more innovative. Photographers can view the object on the LCD screen before and after clicking the camera. It is the most advantageous feature of it which enables deleting of unwanted photos then and there. However, LCD screens require additional battery power. Another version is the electronic view finder which is gaining popularity among the users.

Re-chargeable batteries are a better option although they are costly. Some of the digital cameras will have AC adapters to facilitate supply of power directly from mains. New digital cameras provide various facilities like built-in pop up flash, auto focus and automatic image stabilization. Size and weight of the camera varies and shoppers have to decide about them in accordance with their tastes and convenience.

Tips for Planning a Good Party

The very first thing that you should do when you are planning on having a party is to have a theme decided. If you decide the theme first it helps you figure out what you will be serving, your decorations, and also your music. Your menu will be the most important part of your party, so choose wisely. Start your planning about four weeks in advance, to get all you will need and give your guests ample notice.

Once your menu is set, checking the Internet for theme ideas can be very useful. Most parties offer finger foods, and you should as well. Never forget your budget, and make sure to give yourself enough time to plan ahead. Homemade dip and relish recipes are also available online. Be sure to test them first, before serving, to see if you like them.

The night before the party you should think about setting up the table. It is very attractive to serve platters on different levels. Creating a slightly elevated platform in the center of your table surrounded by decorations adds a nice touch.

The day of the party will force you to bring everything you have planned together. Final preparation and cleaning should begin about 30 minutes before guests arrive. Getting the lighting and music set before guests arrive is a good idea. Don’t forget to leave that last hour for you.

Platters of food will easily stay warm if you use hot plates, and this will grant you less to have to worry about. Don’t be in a big hurry to clear off the table it is a big party bummer if this is done quickly. Ask your friends to bring their digital cameras to help capture the fun.

Afterwards, your guests will show their appreciation for your hard work. You will look over your digital slr pictures for many weeks to come. All of the people that had been there will remember how great of a party it was and will be talking about it for months, until the next one.
