Capturing times was never really easy before digital camera models came into the photography world. From the time, there has been a major international market dealing with digital cameras. Japan, South Korea and China have been the major participants in manufacturing new digital cameras since its inception. Today, no press house can work without digital camera models. Ignore media agencies, in our day-to-day life, we have started as a handbag’s must-keep product considering digicam. It’s really given a new definition to the world of photography. Today several types of digital camera models with different features are hovering across the market. And you need to decide on your options and pick up the right one that suits your pressing needs. You need to have already heard a lot concerning the leading manufacturers such as Kodak, Nikon, Canon, Minolta, Sony, Panasonic, Polaroid, Olympus, Fujifilm, HP, Samsung, etc. This informative article examines options that come with popular brands and types of digital cameras to allow you to select the right one on your own. To start your selection process, you must consider whether you are looking for small and compact pocket camera, an advanced camera, a large zoom capability camera, or an SLR camera. These can range from USD 100 to USD 2,000. You will have to take your pick based on your needs and budget. What are the functions that you ought to compare between models while selecting a digital camera? The most significant feature is its quality in mega pixel. In simple language, this number tells you how much it is possible to develop your picture without parting having its quality. The higher the resolution, the better. But this doesnAAAt signify you have to choose the highest available model in the market. Usually people print images that are measured 4×6 or 5×7 inhes. So for these picture measurements, any camera above 4 mega pixels will deliver great results.Other feature that you need to consider is zoom-in capability. Optical focus and digital zoom will vary terms. Optical zoom means true zoom done by the lenses, while digital zoom merely increases the size of the image screen without increasing any facts. In basic terms 3x optical zoom means you can get 3 times closer picture of the image you see along with your eyes. That is why, optical focus is better.The third important element is compatibility with other units. If the camera you are going to buy is appropriate for your computer, printer, storage device, USB travel, etc find out. Cameras have integral flash memory nevertheless the area is limited, so you would need to buy additional memory cards, widely called Secure Digital Card (SDC) and Multi Media Card (MMC). The next important function is the measurement of the screen that delivers digital display of the image immediately. These displays were the major reason that digital camera models replaced conventional cameras so quickly. The screen offers you the power to examine the image and remove the ones you don’t like. The LCD digital camera screens are around 3 inches in thickness. The other characteristics which make your camera more convenient include automatic light adjustment, automatic display, red-eye reduction, extendable (TIFF, RAW or JPEG), audio and video functionality, image stabilizer, manual controls for aperture and exposure, camera velocity, weight and size, body type, battery form (lithium of normal), battery life, picture modes for morning light, day light, dark day, etc.The varieties and features of digital camera models are so many that it becomes very hard for a first-timer to choose one. This is worsened by everyday technological advancements. But all the features mentioned above impart a whole new dimension to photography and they make it easier for even an amateur to press great quality pictures.

Do you dislike having your picture taken because you always seem to come out looking hideous? Have you ever felt jealous of your friend who always comes out flawless in photos? What’s the deal with pictures? While being photogenic just comes naturally to some people, there are a few things that anyone can do to look better in photos. Try out the tricks in this article and stop running for cover whenever the camera comes out.
Ever wonder what it is that actually makes a camera work? This tutorial will cover the inner workings of a camera, and introduce you into photography basics and the expansive world of taking better photographs.
To take beautiful photographs you do not need an expensive camera and a bag full of equipment. What is important is the photographer’s ability to see his/her surrounding and use knowledge and personal feel for the subject.
Being the first article in a series, this lesson is meant to only cover the basics of photography. The idea with this series is to get people more interested in photography, awaken creativity and hopefully help people enjoy this hobby even more. The community here at Tutorial9 is an important part of this series and I would love to hear your feedback and questions.
The word “photography” is French but is based on Greek word and literarily means “drawing with light“. That’s what photography is all about, without light — no photograph. The art of photography is basically seeing and balancing the light.
The illustration to the left shows the path the light travels from the object to the sensor (or film in non-digital cameras).
First the light needs to go through the lens, which is a series of differently shaped pieces of glass. If the focus is good then the light will meet on the sensor.
The aperture is placed inside the lens and is basically an opening that controls how much light reaches the sensor.
On most modern cameras the shutter is placed inside the camera body. This piece of mechanics is what controls how long time the sensor is exposed to the light.
The sensor is a very sensitive plate where the light is absorbed and transformed into pixels. As you can see on this illustration, the image the sensor picks up is actually upside down, just like our eyes sees the world, the processor inside the camera then flips it.
Aperture
The aperture sits inside the lens and controls how much light passes through the lens and onto the sensor. A large aperture lets through very much light and vice versa. Knowing how the aperture affects the photograph is one of the most important parts of photography — it affects the amount of light, depth of field, lens speed, sharpness and vignetting among other things. I will talk more about these things in later parts of this series.
F-numbers, a mathematical number that expresses the diameter of the aperture, are an important part of understanding how the aperture and exposure work. All f-numbers have a common notation, such as ƒ/5.6 for an f-number of 5.6. There are a set numbers of f-numbers that are used in photography, there are several different scales but the “standard” full-stop f-number scale is this:
ƒ/# 1.4 2 2.8 4 5.6 8 11 16 22 32
These are known as full-stop f-numbers. If you decrease the f-number with one full-stop, like ƒ/4 to ƒ/2.8, the amount of light that passes through will double. If you increase the f-number with one full-stop, like ƒ/5.6 to ƒ/8, only half the amount of light will reach the sensor.
There can be several f-numbers between the ones above — depending on what scale is being used. The most common one is a 1/3 scale, which means that every third step is a full-stop, and thus giving you two settings between every full-stop. For example between ƒ/8 and ƒ/11 you will find ƒ/9 and ƒ/10. This can be rather confusing at first, so here’s a short reminder:
A higher f-number = a smaller aperture = less light
A lower f-number = a larger aperture = more light
Shutter
The shutter is what controls how long the sensor is exposed to the light. The longer the shutter is open the more light can be captured by the sensor. A fast shutter speed will result in “freezing” a moving object and a slow shutter speed will let you capture the motion of a moving object.
There is a scale of stops for the shutter speeds just like for the aperture, below are the full-stops.
1/1000 s 1/500 s 1/250 s 1/125 s 1/60 s 1/30 s 1/15 s 1/8 s 1/4 s 1/2 s 1 s
And just as with the aperture, the shutter speed is often on a 1/3 scale, giving your two steps in between every full-stop. For example between 1/60s and 1/125s you will find 1/80s and 1/100s.
The two primary factors which control exposure are shutter speed and aperture. We will cover these things in greater detail in other lessons.
See [LINK TO EXPOSURE TUTORIAL] for an article on how exposure works.
ISO
The ISO speed (the name comes from the International Organization for Standardization) is a measure of the film speed, or its sensitivity to light. With digital cameras the ISO affects the sensor instead of the film, but the principal is the same. A low ISO speed requires a longer exposure and is referred to as slow, a high ISO speed requires less time to give the same exposure and is therefore referred to as fast. One step in the ISO equals one full-stop, so the ISO is not on a 1/3 scale — film can be found with 1/3 ISO speeds, but it’s uncommon in the digital world. These are the most common ISO speeds.
ISO 50 100 200 400 800 1600 3200
On 35mm film, a film with high ISO speed had much more grain than a slower film — but the modern sensors don’t create the same grain with high ISO speeds. Instead it creates noise. The digital noise is not as favorable as the film grain and can destroy a photo if it’s too visible (the same goes with the grain, but it’s effect was more subtle and often more liked).
If light is no problem, then always use a low ISO number but if you’re indoors with bad light or other conditions when you find the combination of aperture/shutter not to be enough the ISO speed can be a great asset. New digital sensors are constantly developed and the noise levels with high ISO speeds are decreasing with every new release.
If you’ve got a great picture you just love, why not get it printed on canvas? Printing photos on canvas lends a unique decorative touch to your home, one that you would be proud to display!
Here’s some ideas on printing photos on canvas:
Top Photo To Canvas Tips For Treasured Memories
by David Donoso
Digital cameras have opened up the world of photography both to the professional and amateur alike. Cameras are becoming increasingly sophisticated and compact and we snap away constantly, building up huge digital archives of images. That’s often sadly where the creativity ends, we store but fail to display.
It shouldn’t be like that, the digital resolution of the cameras is now so high that printing out large prints is cheap, easy and of high quality. Getting standard glossy photo quality prints would be a better step but for the ultimate way to display treasured memories, photo to canvas is without doubt the way forward.
Photo to canvas allows you to showcase photographs in an alternative medium that really stands out. For the best results follow the tips below:-
* Invest in quality. Look for canvas that has a high GSM rating and that uses FSC approved wood. Wood should be ideally kiln-dried and anti-warp so that you get true longevity in your products. Make sure that the printing inks are also of the best quality to stop fading over time.
* Seek quick delivery. Source a photo to canvas expert that will give you next day delivery. Online sites should have the functionality for you to quickly upload your images and start the process. Once uploaded, the manufacturer should be able to turnaround your order quickly and efficiently.
* Get expert creative advice. Find a photo to canvas expert that can also carry out photo restoration and optimisation. No point in having a large canvas with someone with red eyes!
* Get testimonials. Only buy photo to canvas products from someone who is reputation backed and has testimonials and reviews from satisfied clients. Testimonials speak much higher than any marketing or sales blurb – a happy client is highly indicative of good product.
