Digital photography brings with it a whole new set of terms and abbreviations that requires getting used to if you've been using film cameras in the past. Many of the terms are totally unique to digital cameras and photography, and if you don't understand them there is a good chance that you won't be able to get the equipment that you really need for taking digital photographs. So let's review some of the most important digital photography terms to help you understand them.
Pixel - everything in digital photography actually begins with the pixel. Simply put, it is the very smallest part of a digitized image. You can think of it as a.dot that when combined with lots of other dots around it, makes up an entire photo image
Resolution - this usually has to do with the total number of pixels in a photograph, and the higher the resolution, generally the sharper and better quality the picture is.
Megapixel - this simply stands for one million pixels. The more pixels that make up a photograph, the higher the resolution and better quality the image will be. So a digital camera that takes a one megapixel image will usually not have anywhere near the image quality of a camera that takes a four or five megapixel image. And the differences become even greater when the photograph is enlarged.
DPI - this stands for dots per inch and often applies to printers or monitors. For instance, most laser printers have a resolution of around 300 dpi, whereas most monitors display only 72 dpi. Photo quality inkjet printers usually come in at least 1200 dpi.
Megabyte - this stands for an amount of computer memory that is somewhere around one million bytes of file storage.
JPEG - this acronym stands for Joint Photographic Experts Group and is now a recognized format for the storage of images is in most digital cameras.The JPEG format allows for quite a bit of image and file compression, making files that are in this format much easier to display on the internet and send to others by e-mail. However, the kind of image compression that is used by the JPEG format can also cause some loss of image quality and so is not suitable for high quality prints.
Memory card - all digital cameras have to store the digital files on some kind of removable media, and most often it involves the use of a small memory card. These cards come in various sizes depending on how much storage space they have available. A few digital cameras are also able to store files directly on CDs instead.
LCD - this stands for Liquid Crystal Display, and these are usually found on most digital cameras to help the photographer preview the scene before taking the photograph, and then review that image later on after the photo was taken.
These are the digital photography terms that are most commonly used today, and understanding them will help you better select and use the digital equipment that you buy.

How to take a Photograph out of a Plane Window
Here’s a quick set of tips for those of us lucky enough to be taking a trip in a plane and wanting to get the classic ‘out of the window shot’ that often is featured early in a travel photo album.
One common mistake that people make with taking this shots is to put their camera’s lens right up against the glass of the plane window in the hope that it will help cut down on reflections and in the hope that it will steady their shot.
While it might help a little with reflections it generally does anything but steady the shot and will often usually increase camera shake’ due to the vibrations of the plane.
A better strategy, if you’re using a DSLR with a fitted lens, is to attach a lens hood to your lens and get in as close as you can to the window without actually touching it.
Alternatively, use your free hand to cup around the lens as much as you can to shield it from reflections.
Of course for high quality aerial shots you’ll want to shoot out an open window from an appropriate altitude – but then most of us are not in that league so the window seat on an airliner is our best option.
Here are five more tips that come to mind on photographing out a plane’s window:
1. Switch to Manual Focus
Quite often cameras get confused when shooting through glass (and on most planes its two or three scratched and marked sheets of glass). Switching to manual focussing mode and locking your focus on your main focal point can help a lot.
2. Shoot early in the Flight
Windows tend to ice up or get condensation on them once you’ve been flying for a longer period of time. Shoot early when you’re window is clearer and your shots will be better for it.
3. Be ready for the Plane Banking
It is difficult from an airliner to take shots of the ground (due to window size and the angles that are possible through them) but opportunities do present themselves for such shots on the few occasions that the plan banks before landing and after take off. The key is to be ready and to shoot fast as these moments don’t last long.
4. Turn off your Flash
For starters it’ll have no impact on your shot (its not strong enough to have an impact beyond a few meters) and secondly it’ll just cause reflections against the window.
5. Look for points of Interest
Sometimes the scenes out of plane windows seem quite spectacular to the eye but when you look at your photos they can be a little empty and un-inspirational. Look for a point of interest to bring your shot to life. It might be the wing or engine of the plane, it could be a cloud formation, another plane, a coastline, a change in the landscape below or a setting sun etc. It could even be something inside the plane.

Photo catalog record
There are several important factors that photo to be taken into account for each catalog. Because a catalog photo is main purpose to help sell the product it is important to ensure that every single one of these important factors carefully considered is, deliver your brand the best chance of success in a highly competitive market.
One of the first factors that must be considered is clarity. Obviously, it makes sense to you, that your catalog shows photo should make sure the product in a unique way, clearly show the product in a way that is neither confusing nor distract so that customers who see best chance looks exactly like the product. This is easier said than done, of course, and there are many obstacles on the way to the creation of a photo of advertising this achieved. Many items of jewellery can look at the end like glass, mirror can reflect the Studio or the lights in a way that is disturbing and food can set up often clearly unfit, if you shoot a full, that number will take more than a few minutes. Clarity is important, but it is not the only factor taken into account.
Another element in the success or failure of a catalog is how effectively it stands out and attracts the attention not only of anyone, but your target group photo. If you ever have found captured your attention by a certain display, posters or photo that you well may questions would be, why. What was it about the special photo that your eye caught, and what was it about the many other images in the vicinity which are not? The answer is probably that the image or photo was designed to appeal to you in any way. Maybe it’s a lifestyle, aspirations, or attitude, but an advertising photo – receives it to not only clearly shows a product, it is effective also on sale.
A third question is to examine, society. This is important, because out there you need are your brand apart from many other companies to sell the same or similar products. It can only a pencil, but how can you it in a way that is both clear and appealing to your target audience, as well as it in an original way the appearance of photography? I find that most of your competitors show the whole pencil, the necessarily from a distance will be, and bearing in mind that you can show your product clearly by it very close up shot of only the top and first half inch of the pencil. Perhaps is a grainy, structured sheet parchment song with one artistic pencil mark elegantly positioned in shot, and a soft focus on the edges. This is just one way in which an image clearly can point in a way, the may appeal to your target hearings (calligrapher, artist, etc.) and it shows your product in a way that more than used by your competitors is original.
A fourth issue is cost, of course, because size for many small and medium-sized companies, the it impossible, the high cost of many professional catalog of photo studios applied provide can be. It is however worth bearing in mind that although you have seen prices announced, that are easy on your budget, means that’s not to say that it cannot not yet Studios ready to help you. In fact, there are professional Packshot photography studios invite less than professional catalog photo shoot, and they are almost certainly in a position ?10 for one to help, on the other three aspects to, including clarity, appeal and society provide. If you are looking to sell your product, rather than just admire how your warehouse is full, then make sure that everyone adheres catalog photo that you use to these four factors.
