Digital Hardware

Digital Cameras, printers and scanners are not absolutely essential hardware for your PC but by and large, you will rarely find a small business nowadays without at least two of the three peripherals.


Various reliable sources have estimated that very soon, the only people who will prefer film cameras will be those who want the cheap, single-use disposable cameras and professional photographers who want to create certain effects that they only feel with film. Can digital technology ever push film out as Joe Soap’s choice for capturing and storing his precious image memories? Well, as we discovered, the answer is most definitely yes.


Digital cameras give you an impressive array of special features and modes that photographers could only dream about a few years ago. You can look at an image in the LCD viewfinder immediately after shooting it and know whether you got the photo you wanted. If not, you can delete it and try again, because there is no film or processing costs. You can quickly upload images to your PC if you want, but a number of cameras don’t even require a computer – they transmit images by a CompactFlash (CF) modem plugged directly into the camera.


Storage isn’t a problem anymore. The addition of a MicroDrive allows you to store hundreds, even thousands, of images without reloading. The applications are endless – especially with the time-lapse and remote-control capabilities available on some cameras – making them suitable for science, medical, nature, and surveillance work. Other digital cameras offer video, and some can record sound annotations with each frame. Many have panorama modes, manual controls, the ability to synchronize with an external flash, or burst modes for shooting up to 2 frames per second at full resolution. And of course, your web pages can be totally transformed quickly and easily by posting images taken with a digital camera directly onto your site.


Bear in mind that while two-million pixel digital cameras are more than adequate for most homes and small offices, enthusiasts and avid photographers will need to invest in at least a three megapixel model.




Scanners, once only the domain of design houses and printers, have become almost as common as printers. Over the last couple of years, the scanner has become quite inexpensive and relatively easy to use, making it a worthwhile addition to any home or business PC setup. And you can now easily incorporate exciting images into your presentations, Web pages and brochures.


Essentially, a scanner is an array of photosensitive silicon cells that measure the light reflected off – or transmitted through – an original. Those measurements are then mapped onto levels (for example, 256 levels per primary color for a 24-bit scanner) by an analogue-to-digital converter, and stored as binary digits that you can view and manipulate with your computer.


For most models these days, initiating a scan is as easy as pushing a single button on the scanner itself or on the interface. The use of parallel or USB interfaces in most of the latest models has eliminated the tortuous task of installing a SCSI board. The design and construction of even the least expensive scanners showed that they were able to deliver perfectly good images for the average user.


As a general rule of thumb, the minimum color depth you should consider for scanning photos and documents is 24 bits (8 bits per color or gray shade). But even the best 24-bit scanners suffer from noise, which means they fall short of the dynamic range of a typical photograph. In theory, a higher bit depth should always be better than a lower, but unfortunately this isn’t always the case. For instance, some manufacturers use a 24-bit CCD and combine it with a 10-bit rather than a standard 8-bit ADC to stretch the output range of the colors into the shadows and highlights. So, in this case, a very good 24-bit scanner can still give you better images than a mediocre 30-bit one.


On the other hand, if you’re scanning slides, negatives, or transparencies, which have a broader tonal range than printed photographs, 30 bits is the absolute minimum you can get away with.




It’s a well-known fact that laser printers have major speed and quality advantages over their fellow print partners, the inkjets. But if this is so, why doesn’t everyone have a laser on their desks? Well, up until now, the laser printer has also had to cope with some seriously ‘big’ disadvantages – high price and huge heft. But, the good news is that the latest batch of lasers has definitely slimmed down on weight as well as in price.


If you print loads of text-heavy documents and are hardly impressed with the print quality of your inkjet, then the laser is calling out to you. (Don’t part with your inkjet though, if you need to print color documents or photos.) Not only are lasers zippy and sharp, but their consumables are much cheaper too. A laser’s toner cartridge may cost more than an InkJet’s ink cartridge but it lasts much longer, which all adds up in the long run, especially if you do a lot of printing.


The laser is a robust workhorse and can fit in quite well in any business environment.

Underwater Photography

One of the highlights of scuba diving is appreciating how amazing and colorful life is underwater. It is so breathtaking and different that it is often difficult to explain to a non-scuba diver just how pretty it is. The only way people who don’t dive can understand the marvels of underwater marine life, the coral reef and the impressive array of colors is to look at underwater photography.

Most divers get their first taste of underwater photography during their Advanced Open Water diving certification, when it is offered as one of the specialties. It is at this point when they realize and begin to understand the complexities of snapping photos underwater.

Underwater photography is one of the most complicated and challenging forms of photography. Expensive, specialized equipment and well-honed techniques are needed. The major problem with taking photos underwater is the loss of color and contrast when at significant depths. Some colors, particularly red and orange, are the first to be lost underwater, because of their longer wavelengths, so everything appears blue-green. It is also very difficult to photograph things that are a certain distance away from you. To counteract these problems, dive photographers always take photos from as close up as possible, and use very wide-angle lenses.

To be a good underwater photographer, you usually have to be quite a proficient scuba diver, and have your buoyancy under control (a skill which comes with diving practice). Snorkelers can also take photos underwater, but they are limited in depth and also how long they can spend underwater.

Digital cameras are preferred for underwater photography, and many waterproof housing cases can now be purchased and fitted to your everyday land camera. To compensate for the fact that many normal cameras do not have wide enough lenses, some of these casings are complete with a dome shape in front of the lens to act as a wide-angle lens.

To compensate for the lack of light and consequent lack of colors, divers can use flash or strobe technology, but it is complicated. Usually, artificial light is combined with natural sunlight to preserve colors, but in the case of wreck, or cave diving, this is not possible and flash or strobe is used alone.

Another point to bear in mind is that people naturally hold their breath when taking photos. Underwater, holding your breath can be a deadly mistake, so photographers should consciously breathe throughout the photo-taking process.

Digital Cameras

Cameras have become a staple item to have in any modern family. There is no better way to capture a cherished moment with your family or the landscape of the place you take your holiday and keep it with you in an album, photo frame or wallpaper on your computer. Digital cameras have made it even easier for your memories to live on in print, innovating the way we store our photos and eliminating the need to purchase camera film. Most digital cameras have USB capabilities that allow you to send the photos straight to your personal computer, meaning you no longer have to take them to get them developed.

Most digital cameras these days have abolished the need for viewfinders, allowing you to see the picture in a more accurate representation of what it would look like in print. This means that no longer will you receive your photos back from the development studio only to realize that your lens was smudged or the camera strap was in the way. With a digital camera, you are able to review the photo immediately and fix any nuisances you didn’t notice before.


Digital cameras have made the lives of both budding and professional photographers easier, too. With the ability to move the photo straight from the camera to the computer via USB technology, computer programs have been developed that allow photographers and amateurs alike to edit various elements of a photo, from lighting, colours and effects like sepia and monotone; anybody can now take the perfect photo.

Digital Camera

A camera that takes video or still photographs or both is called a Digital Camera. The Digital Camera is done through recording by way of an electronic image sensor. A display image on a single memory device is one of the functions a digital camera. It can also record video with sound. You must however, delete some of the images to free storage space.

Digital cameras contain numerous devices that can be built-in from PDA’s and mobile phones to vehicles. Some of the called particular digital cameras are The Hubble Space Telescope and other astronomical. One of the most amazing instances of digital cameras is that the said camera is so really different from its predecessor.

The figure of pixels determines the greatest size of the resulting image and its sharpness, especially when printed. The higher the resolution of the start, the better is the result. You cannot go from low to high with great income, however, you can lessen a high-resolution image to low resolution in the computer. Other use of digital cameras is that you can also come with memory slots that hold a memory card or “stick”. 

The sum total of memory available in the digital camera ranges from megabytes to gigabytes. Of course, the more memory of the digital camera, the greater will be the cost. However, the additional storage capacity may be well worth the additional expense.

Once a picture has been taken, it can already be downloaded to a computer system. You can also insert open programs and print it. If we evaluate it to film photographs which have an almost infinite resolution, the digital photos has a limited quantity of memory. Even the best digital cameras associated to the finest printers. Digital cameras cannot produce film-quality photos.

Digital cameras are different from conventional cameras. Digital cameras have a small LCD screen and sometimes an LCD screen plus viewfinder. The photographer is allowed to see more of the subjects and background in the large screen. They can also review the complete image immediately and erase the others.
One of the advantages of digital cameras is that the finished image can review immediately and you can also erase the other images that you do not like. Secondly, you can also get and print one picture without waiting to develop an entire roll of film. Lastly, the storage mechanism and memory cards mostly widely used for digital film are reusable over and over.

Before making an expensive purchase, camera buyers should know at least the basic features of their camera of choice. Even if the snapping of pictures is basically the same from camera-to-camera, there are features that make one product more appealing than others.

One of the most interesting parts of digital cameras is that you can easily save the photos in your computer unlike the film cameras. Film cameras must be developed so that we can see the pictures. And the great thing with digicams, you can easily upload pictures in YouTube, Friendster, MySpace or Facebook account unlike film cameras that we must scan first the picture so that we can upload it.

Digital Camera Help

If you are fairly new and want some digital camera help, then let’s cover some of the more common things to help you get started.

The Basics

A digital camera captures the image when the light from an object is focused and falls on a light sensitive sensor within the camera. Each camera’s sensor has tiny little pixels on the surface and the number of pixels determines the highest quality of the resultant image, and also the class of the camera. So a camera that has 4million pixels is known as a 4megapixel camera, and so on.

How many pixels do I need?.

As the number of pixels increases, normally so does the price, and sometimes the size of the camera, so choosing wisely will save you both money and effort in carrying. If you want to print standard photo size prints then a camera of 3-4 mp will be adequate, but if you want to print large A3 prints at a good quality, then you really need a camera of about 6mp+. Remember you can adjust the quality down but you can’t use pixels you haven’t got.

Bells and Whistles

•LCD Screen -Normally on a digital camera you will be framing the shot and reviewing the shot on a small screen at the back of the camera, make sure it is of a decent size and you can view it in sunlight.

•Scene Mode – Allows the camera to set optimum settings for a selected type of shot.

•Focus Points – You have the ability to select a point or area that the camera uses to focus, invaluable when shooting small objects against a bright background.

•Zoom – Optical zoom is better than Digital Zoom so try to get a camera with the highest optical zoom.

•Macro – To enable you to get really close focus, and try for those real ‘Arty’ shots.

•White Balance – Adjusts the camera to compensate for color-cast when shooting under artificial lights.

To give you the best digital camera help, these are fundamental to your enjoyment and results . So take care in selecting. Remember price alone does not guarantee results.

Portrait Photography Success

Creating photography portraits can be a rewarding experience. It is however it is a skill like so many others in which practice makes – if not perfection, at least close to perfection. Learning from the experience of others is another key to the path to portrait perfection. This article offers several suggestions that photographers can follow to perfect their craft.

1. Before the shoot, give the clients a checklist they can follow to prepare for the shoot. Included items would be what kind of clothing and makeup to wear and what to do with glasses during the shoot.

2. Encourage your subjects to have good posture. This can be done by placing lightly touching your client’s lower back with two fingers with one hand while you touch them on the front of the shoulders with the other hand. Doing this while you say “good posture please” will almost always improve your client’s posture.

3. Be aware of the size of your subject’s heads and hands. These are usually the parts of the body which draw the most attention. If the hands are too close to the face with the full palm or back of the hand showing, it can overpower the face.

4. Often, when a photographer is photographing infants, the mother will want her portrait taken with the infant. Remember this mother just gave birth. Her mid section may not be the most flattering. Try and get more of the mother’s face in these shots.

5. When photographing newborns, allow more time than what is required to photograph an adult. Newborns eat, sleep and play when they want. They do not follow instructions well. As a result a photographer needs to have more patience (and time) than he does when photographing adults.

6. When photographing couples kissing ask them not to pucker up. While puckering up may look perfectly natural when seen in real time, it looks unnatural when frozen in time.

7. Ask your clients to bring props which will help personalize the shot. While it may be fun for the photographer to direct the shot as he sees fit, it is the client who is paying the bills. Make sure his/her personality is manifested in the results.

Portrait photography can be a rewarding. It can also be challenging. Following above suggestions will help ensure that there are more rewards than challenges.

Vanessa and Stephen shoot portrait, senior, engagement, pet, wedding, and family photography session. They shoot most often in the OC, San Diego County, Los Angeles County, and Riverside County.

Digital Descriptions

They say a picture is worth a thousand words. Yet, all too often, people come to coaching using just a single word (i.e., a label) to represent how they see something, such as, “I am a writer,” or, “He is a leader,” when in reality the label lacks specificity and represents a vague picture of HOW things really are (i.e., their reality). As a coach, I prefer using digital descriptions instead of labels because I believe they paint a clearer picture of reality.

Let’s explore digital descriptions and how useful they can be, starting with the letters in our alphabet. When you think about it, letters are really just symbols that we use to construct words and labels. And when you assemble the words/labels into a description, a picture emerges. So, think of words/labels like pixels (i.e., colored dots), which are used to form a digital picture. A single word represents a single pixel, so the more words (pixels) you use, the clearer the picture becomes.

I will illustrate digital descriptions by using our digital picture metaphor. Think of the label “tree” as a single green pixel in a digital picture of a tree. With no other pixels, the picture would just be a green dot and look nothing like a tree. Add a thousand other colored pixels one by one and a specific picture of a tree comes into focus. In a similar fashion, let a green pixel represent a label (e.g., tree). With no other words, the picture would just be vague and lack specificity in the representation of a specific “tree.” As words are added to the description (e.g., large, tall, robust, oak, winter, positioned on the side of a mountain, in fall), the number of words increases, thereby bringing more specificity to the exact image of the specific tree in the specific environment in which it exists. Thus, if a picture is worth a thousand words, a description needs a thousand pixels to clearly represent what is real.

Digital descriptions can have a profound impact in casting (or miscasting) one’s role in life. Let’s assume there is a need for a leader. Before we can cast the right person, we need a clear picture of exactly what kind of leader we are looking for (i.e., his/her attributes). To attain a clear picture, we need descriptive words. To do that, we need to question the label: What exactly is a leader? What attributes make up the kind of leader we are looking for? How would we find a person with such attributes? These open-ended questions may be challenging, but they are critical in the formulation of a digital description. The following are sample digital descriptions of a leader: 

A brave soldier who is the first one onto the battlefield.
A person who has the specific knowledge to get our troops safely onto the battlefield.
An articulate, charismatic individual who can inspire our troops and motivate them to go into battle.
A person who can be held accountable for the success or failure of our troops on the battlefield.
Different combinations of the above. 

As you can see, each description brings clarity to the different kinds of possible leaders and key attributes (i.e., bold words) that one needs to possess. A digital description brings your attention to what you should be paying attention to. By just using the label “leader,” we run the risk of miscastingour leader. Imagine the impact of casting an articulate, charismatic leader as the person who is in charge of getting our troops safely onto the battlefield. We would have a motivated group with no knowledge about how to get where they need to go. In the end, digital descriptions reveal subtle but profound differences in the picture of the leader needed and his/her associated traits. The lesson here is simple. Labels, generalizations, and our keep-it-simple culture only serve to misdirect our attention, thereby inhibiting our ability to clearly see what is real (i.e., reality). So, the next time you get stuck and don’t know how to move forward, pause and consider using digital descriptions to describe more specifically what is going on. Like pixels in a picture, the more words you use to describe the picture, the more your picture will resemble what is actually real instead of what you believe is real.
