2). How Many Pixels Make A Good Print?
One of the more common dilemmas for people is choosing the paper size for printing their photos. Everybody knows that if your digital camera does not produce enough pixels (or actually megapixels) printing its photos on a large paper size will yield poor quality and you will be able to see the actual pixels (also known as pixelation)
So how many megepixels do I really need in order to print on a specific paper size? there is no one right answer for that.
3). What is DPI – Dots Per Inch?
You have probably heard this term many times before especially in the context of printing your digital photos. DPI is sometimes used as a measurement of digital photo printing quality while the truth is that DPI is an indicator of the printer quality.
DPI stands for Dots per Inch. DPI is a physical characteristic of a printer. Every printer prints dots that when put next to each other comprise a photo.
4). Tips for buying your digital camera
So you have decided to get a new digital camera? or maybe it is your first one? Like many other consumer electronic devices digital cameras change all the time. For the same amount of money you can get more and more features: mega pixels, storage space, zoom and more. In this article we will give you a few practical tips for what to look for and how to best pick your camera.
5). How Does the Camera Auto Focus Work and Why Sometimes It Fails?
How does auto-focus work?
All of us use it every time we click on the shutter button. Practically all modern cameras include some sort of an auto focus system. Thanks to the auto focus system we can enjoy an easier photography experience and can concentrate on composing the right photo and capturing the moment rather than on manually setting the focus.
6). Turning Your Photos To Cash - How Can Your Photos Make Money For You

7). Effective use of Flash Photography
Did you ever put your flash unit in manual mode? Did you ever manually turn on the flash when taking a day time outdoor photo? For many the answer to both questions is “no”. For most amateur photographers flash is just a solution for taking photos when there is not enough natural light. Although a legitimate use of flash photography there is much more ways to efficiently use flash.
8). Understanding what the anti dust feature is in digital SLR cameras
Digital cameras use a sensor known as CCD in order to convert light energy to pixels. Dust that accumulates on the CCD can result in black pixels or imperfections in the photo as it blocks light energy from hitting parts of the CCD. We will go over a few solutions for eliminating dust on the CCD.
The CCD sensor is located behind the reflex mirror in a digital SLR camera.
9). Exposure value (EV) and exposure compensation
Exposure is defined as how much light hits the camera’s sensor. It depends on the camera settings mainly aperture and shutter speed. Exposure value (known as EV) is a number that represents the exposure setting of the camera. We will explain what the number means and how it is used for exposure compensation.
The exposure depends on two things: how much light gets through the lenses to the camera’s sensor and for how long the sensor is exposed.
10). Selling products online with the help of digital photos
The old saying “a picture is worth a thousand words” was never more true. In the digital photography era photos can be used in more types of media than they could have before. Not limited to paper prints they can be used on web sites, in emails, in cellular phones, projected in presentations and more. When selling products online photos are a powerful tool that you must use.
11). Keep Your Photos Safe
Are your precious photos safe?
Are you backing up your precious photos? our computers and removable storage media are full with experiences and precious moments. However electronic media is not safe. Hard disks crash and removable media fails.
Disasters can happen. Digital photo albums are vulnerable and if not backed up you lose thousands of photos and a lifetime of moments in just one hard disk crash.
12). Optical or Digital Zoom? The Choice is Clear
What is zoom?
Sometimes when you take a photo you need to focus on one area in the picture frame. For example when you take a portrait photo you want to make sure the object’s face fills the photo frame while when you take a group photo you want to make sure everybody is in the photo frame.
In to focus on that one area in the photo frame you can either physically move closer to the objects or use the camera’s zoom feature.
13). The Difference Between DPI and PPI
Most people heard the term DPI. In most cases the term is used in the wrong context to express the number of pixels in a photo, the number of dots in a print or the maximum dots per inch a printer can output. A relatively new term PPI was introduced in order to resolve this wrong usage of the term DPI. In this article we will try to explain in simple words what is DPI and what is PPI and should each be used.
14). What is PPI – Pixels Per Inch?
The term PPI is not used much. Many people confuse PPI with DPI or have never heard the term PPI. PPI is a measurement of the quality of a print and understanding this term and what the number means can help you determine the right sizes and resolutions for your next digital photo print.
PPI: stands for Pixels per Inch. PPI describes the number of pixels per inch in a photo.

We also want to share those photos with our family and close friends and by that to share our experiences. In this article we will go over a few options for doing just that.
There are a few methods for sharing photos. Before the digital era sharing was done by printing photos and arranging them in photo albums.
16). Still digital camera image stabilizers - keep your images sharp
Taking stable and sharp photos is hard in some situations. For example when taking a photo using high zoom lenses even the tiniest camera movement will result in a blurry photo. The reason for that blurriness is that while the shutter is open and the photo is being captured the camera moves and the image on the sensor also moves losing its sharpness.
17). Digital photo frames and what to look for when buying one
Digital photo frames are new products that replace old paper photo frames in displaying your photos on a desk, on a shelf or on a wall. This article explains what digital frames are, how you can use them and what you should look for when buying one.

Most of the services work in the same way: once you uploaded your photos to the site you can choose which photos to print at what size what kind of paper and in how many copies.
23). Digital camera modes – shutter aperture priority and more
Digital cameras can be put in different photo shooting modes. The most used mode is automatic – the only thing you need to do is point and shoot. However understanding and using the other options will allow you to get better photos in certain scenarios. Here is how.
We will go over the various camera modes. Some modes might not be available on your camera.
24). Understanding and using auto bracketing
When you shoot a photo you need to set the camera to the values that would result in the photo you want to get. However sometimes it is hard to find those settings or there is just not enough time to figure out what they are – auto bracketing can help – here is how.
There are two main parameters that influence a photo dramatically:
Exposure: Exposure is the amount of light that the camera’s sensor is exposed to as a combination of shutter speed and aperture.
25). Shooting photos in Aperture priority mode
Digital cameras support many photo shooting modes - from automatic point and shoot to manual where the camera does nothing for you. One of those modes is Aperture Priority. Aperture priority is useful in many situations and deserves a short explanation of what it is and how to use it.
You set the Aperture priority mode by using the camera menus on its.
26). Understanding Photo Printing Paper Sizes or What is 4XD?
What is an aspect ratio?
Every photo or movie has an attribute called an Aspect Ratio. The aspect ratio is the relation between the horizontal and vertical sizes of the photo. To calculate the aspect ratio simple divide the width or a photo by its height. For example TV in normal mode has an aspect ratio of 4:3 or in other words if we were to divide the width of the screen by its height the result would be 4/3.
27). Pros and Cons of Battery Technologies Used in Cameras – Choose the Right One for You
Like other portable consumer electronic devices digital cameras use batteries as their power source. In this article we will describe different battery technologies and their cons and pros. Armed with this knowledge you will be able to take into consideration the battery used when purchasing your next camera.
A camera usually supports just one type of battery either a disposable battery or a rechargeable one.
28). Tripods - How to Avoid Blurry Photos
All of us had the experience of shooting photos just to find out they look blurry or too soft. In almost all cases the reason for that is camera movement. When the camera moves while the shutter is open the result is a soft or blurry photo. Usually camera movements are small and for that reason in high shutter speeds the camera does not have an opportunity to move enough.
29). Digital Noise - What Is It? What Causes It? And How Can I Get Rid Of It?
Digital noise in photos taken with digital cameras is random pixels scattered all over the photo. It is a similar effect as “grain” in film photography and it degrades the photo quality.
Digital noise usually occurs when you take low light photos (such as night photos or indoor dark scenes) or you use very slow shutter speeds or very high sensitivity modes.
30). The difference between film and digital photography
There are many differences between film and digital photography. To most amateur photographers they do not matter much. They prefer the convenience, ease of use and lower cost of digital cameras and are not going to revert to the film age. However understanding the differences can help taking even better photos and can also help when debating with friends about the future of film.
31). Understanding Red-Eye in photos and how it can be prevented
Why are eyes red in photos?
Red-eye is a phenomenon that happens only when taking photos using a flash. When taking photos in day light or when in high ambient light scenarios people’s eyes look normal. When taking pictures in low ambient light scenarios using a flash the result many times is redness in the people’s eyes.
The reason for the color red is simple – when flash light from the camera hits the eyes it penetrates and is reflected back from the retina.
32). Methods for photo backups
So you have finally decided to backup those precious photos? There are a few ways to backup photos. In this article we will explain how you can backup your photos either yourself at home or by using an online backup service.
Backing up to a DVD/CD

Although the reason for doing that can vary there are some common considerations to scanning paper prints. In this article we will go over some of them and try to make your scanning experience easier.
There are three types of prints that you might be scanning:
Paper prints: the most common, usually at sizes like 4X6 and 5X7.
34). How to choose a camera with the right number of Mega Pixels?
The race for mega pixels has started and there is no way to stop it. Every few months cameras with more pixels hit the market. The manufacturers want you to dump your old camera and buy the newest and greatest one after all aren’t 10 mega pixels better than just 8? Apparently the answer is not that simple.
As with many other things when it comes to mega pixels more is not necessarily better.

36). Photo printing made easier with DPOF
There are many ways to print photos. For example you could download the photos to your computer choose the ones you like burn them on a CD and take them to a printing service. DPOF makes such photo printing easier – here is how.
DPOF is a standard that was introduced by a consortium of camera and printer manufacturers. The goal of DPOF was the make photo printing easier and faster.
37). Photos that capture moving objects motion
Still photography freezes a scene. A photo is still in nature but sometimes you would like to convey a feeling of motion to the viewer. For example when taking a photo of a moving car or a runner. There are techniques that can help you achieve that – here is how.
You have probably experienced shooting blurry photos usually as a result of wrong camera settings or the object moving while you were taking the photo.
38). Do more with digital photos than just digital photo printing
When digital cameras were first introduced they were used mostly as digital replacement to film cameras. Users would shoot photos, print them and archive them in photo albums. As users became more sophisticated new ways to use digital photos were found. Here are a few.
The most basic thing you can do with a digital photo is print it and view it on paper or save it on a computer’s hard disk and view it on the computer screen.

Lightning photos are very dramatic. The contrast between the night darkness and the lightning brightness results in very powerful photos. In this article we will provide you with a few tips and guidelines for successfully taking lightning photos.
The first thing to do when preparing for lightning photography is to set the camera to manual mode. Since all the preparations are done in a dark environment the camera can not automatically set the right focus, exposure and aperture.
42). Understanding Shutter Delay in Digital Cameras
When using a digital camera to take action photos you will notice that there is a delay between the time you press the shutter button to the time the camera actually takes the photo. In most cases this delay is small enough and not noticeable but when taking action photos, when trying to capture an event that just happened or when trying to capture a moving object this delay can result in a photo that just missed the action.
43). Digital photo printing paper sizes – 4XD 5XD and others
When you print digital photos on traditional paper sizes photos are either cropped or areas of the paper are left blank. The reason is that tradition paper sizes were designed for film and have different aspect ratio than digital photos. Digital paper sizes solve this problem and are offered by many – here is how.
Understanding aspect ratio
Before you can understand why digital paper sizes are different than traditional ones you need to understand what aspect ratio is.
44). How Much Does A Camera Really Cost? Make Sure You Budget Right Before Buying A New Camera
Digital cameras are not different than other consumer electronic products. The cost of ownership is not limited to the sum paid to purchase the camera. In most cases consumers find themselves spending more money on accessories and other additional products. Failing to budget for those extra expenses can result in buying a camera just to find out it is not operable without spending more.
45). The EXIF format in a nutshell
You might have heard the acronym EXIF in conjunction with digital cameras. EXIF allows for additional information such as shutter speed, aperture and resolution to be associated with a photo file. EXIF ensures that cameras can document such information while other software can read and use it. Here is how.
EXIF stands for Exchangeable Image File Format.
46). Orientation sensors in digital cameras
Cameras can be held in two positions: horizontal or vertical (also knows as landscape and portrait). Photos taken in the vertical position are later on rotated 90 degrees (either clockwise or counter clockwise). Rotating the photos can be automated if your camera sports an orientation sensor.
If you just take a few photos every now and then rotating them manually is not a big deal.
