ISO settings on a digital camera

ISO settings
On all compact digital cameras and digital SLR ISO settings can either be manualy set or automatically set by the camera. An ISO setting dictates how sensitive to light the digital sensor should be. The sensor in the camer captures the detail of the image, the data is then turned into digital signals to be stored on a memory card. ISO settings start at around 50 and generally go up to ISO 400, some dslr cameras can go up to 3200. The higher the ISO number the more sensitive the sensor is and will take in more light. Taking a photo out side in bright sun light would mean a low ISO setting maybe of 100 or less. Taking a picture in doors at a party would need at least a 400.

AUTO ISO
The camera decides on the settings, by judging the brightness of the settings. The photographer has no control.

ISO 50 - 100
This manual setting is best used for images taken in bright sun light, portrait and landscape photography. It can be used for macro photography as it also tends to produce better quality

ISO 100
Adds extra light to the image with out any loss in quality, a good use for photography in the shade on a sunny day.

ISO 200
Best used on cloudy and overcast days. Acceptable image quality, though loss in the over all quality of the picture can be detected.

ISO 400 and above
For use when you are unable to use a flash. Also useful for indoor photography whether you use a flash or not. If you intend to take action photos like sports then a high ISO setting with a quick shutter speed will be needed to ensure that you capture the action quickly with enough light.

Use of flash lighting

When taking a photo inside or in a slightly dark enviroment, the digital camera will recommend to use its own internal flash to brighten the scene for you. Once the photo has been taken and loaded on to the computer they can look very dark and the image turns out not as planned. The image below has been taken with the cameras own flash:


The background has come out very dark and not very accurate to what the actual light was at the time. The next photo that was taken was with no flash used, but instead the exsposure compensation was used to increase the sensitivity to light, this means that the camera would increase the amount of light that it captures:


While the picture is slightly blurred you can see how much lighter the image is over all, this picture and the lighting in it, are almost identical to the living area where it was taken. While we at print digital are not saying to never use the flash on the camera, it is always worth while remembering the other features that the camera offes when lighting a shot in a dark enviroment.

Digital Camera Tripod

Have you ever taken a picture and the end picture has been blurred. It can be down to several reasons, the camera could have moved as the picture was taken, if you held the camera the movement as you breath could have affected the image. In certain conditions the image can be more blurred - such as low light conditions when the shutter is open longer. If the apeture is wide open or you use a telephoto lens expect to have a certain amount of camera shake.

There is one essential piece of equipment that can be used that will eliminate a blurred image, a tripod. They can be picked up for as little as £20 and can help transform your images from shaky images to pro digital shots that you will want to frame and put on your wall.

DSLR Buyers Guide

So, you have decided to buy a DSLR digital camera instead of a top end digital compact camera? There are many factors you now need to consider before buying your camera. For example; Canon Vs Nikon, how many mega pixels, kit lens or better etc… the list goes on! Hopefully this handy guide will help to answer some of those questions for you;

Make of camera:

This is a tough one, as to look at the two market leaders, Canon and Nikon, of DSLR cameras there is not a lot to separate either. For many years Canon has been regarded as a high end professional camera manufacturer and has dominated sports photographers as well as photo journalist’s camera bags.

Canon has recently revamped its entry level DSLR cameras with many new additions; Canon 350D, Canon 400D and the Canon 450D.Nikon have recently released new entry level DSLR cameras such as the Nikon D80, Nikon D40 and the Nikon D40X.

Mega pixels:

In basic terms the quality of an image has nothing to do with the mega pixel count. The quality of an image is mostly related to the digital sensor that captures the light.

The amount of mega pixels a DSLR camera has, has an impact on how big you would like to print out your images. The higher the count, the bigger you can potentially print out an image.

Manual controls:

Nearly all DSLR cameras come with full manual controls. This enables you to control shutter speed, ISO setting, white balance, auto-focus (or) manual focus, metering, lens aperture and multiple set programmes.

The above are all basic manual controls that should be found on all DSLR cameras.

Memory cards:

If you are moving up from a digital compact camera you may already have a large collection of memory cards that you are hoping to use with your new DSLR. Not all cameras take the same type of memory cards though.

Canon cameras mainly take Compact Flash cards with newer cameras starting to accept Secure Digital cards. While Nikon take a variety of Secure Digital cards, Compact Flash cards and Microdrive cards.

Kit lens quality:

Another huge factor in the quality of your photographs is the lens that is used. Most DSLR’s come with a lens known as a kit lens. A kit lens tends to be very low quality with cheap glass and components.

It is normally possible to buy a DSLR camera with a better quality lens as a bundle for a very good price. If your budget can stretch this far then it is highly recommended that you do so, the difference in quality can be very noticeable.

Extras:

In the box you can expect some nice extras;
  • Camera body
  • Lens (if applicable)
  • USB cable (to transfer images)
  • Disc (software to transfer images, RAW converter and image management)
  • Manual
  • Warranty
  • Memory card (some cameras come with a memory card, usually a 512MB card)

Holding the camera:

It is essential to hold the camera before parting with any money! When holding the camera you will be able to see how easy it is to get the shutter button to take a photo, or check if the LCD is bright enough for you. Those are only two of many things you should check, always consult with the sales person.

High street or online:

This comes down to personal preference, and if you would like to hold the camera before you buy.

Most decent camera shops will let you hold the camera and even take photos beforehand. I like to grill the sales assistant as well, firstly it’ll make him feel that he has earnt his commission, and secondly they can clear up any questions or doubts you may have. If they stumble or don’t know the answer to any of your questions, ask them to find out. Don’t forget it’s a lot of money that you will be spending with them so make sure you are going to be 100% happy with your camera.

Online does tend to be cheaper, but you don’t get the chance to hold the camera and take some sample images. You also are in the hands of you local postal service or courier company!

Price:

A new DSLR is not cheap; expect to pay in the region of £500 - £600 for a decent entry level camera. Top of the range tends to be £6,000 for the Canon EOS 1Ds MK3.

Kodak Intros Two New Cameras


Kodak today announced two inexpensive cameras featuring image stabilization and the company's Smart Capture feature that automatically recognizes scene characteristics and adjust camera settings accordingly. The Kodak EASYSHARE Z1015 IS is a 10-megapixel model with a 15x optical zoom lens starting at a wide 28mm. The company claims a click-to-capture speed of less than 0.22 seconds. Light sensitivity can be set all the way to ISO 6400, though this level is only available when shooting at 3.1 megapixels or less. Full manual control over aperture and shutter speed are available, along with program mode. List price for the Z1015 IS is $349.95, with shipments slated for September.

The other new camera is the M1093, a compact 10-megapixel point-and-shoot featuring a 3-inch LCD screen and a 3x zoom lens. Face detection is available along with HD video capture. This one is available in black, red and silver for fashion-conscious buyers ready to invest $199.95 when the camera ships in September.

Dell adds storage, disaster management services to portfolio

Dell on Monday announced it was adding customizable storage and disaster management services to build out its services portfolio, which it began revamping last year.

The services, which include disaster recovery and data backup services, will offer tools and consulting for customers to meet exploding data storage requirements across multiple networking and hardware environments, the company said. (Compare Data Backup and Replication products.)

Dell has done occasional storage and disaster recovery consulting, but this is the first time these services are being pulled together as an offering to customers worldwide, said Paul Kaeley, global practice leader at Dell.

Two levels of disaster recovery will be offered to customers. The first level, for midsize consumers, will protect data around key applications and provide tools to restore IT operations in case of a disaster. A higher service level targeted at larger customers will include the design and implementation of IT disaster recovery plans through tools and aligning more people to ensure the plan is effectively implemented.

Dell is also offering managed backup services with reporting and monitoring services to stabilize data backup. If a backup system goes astray, Dell is offering a managed backup through remote management. The services will span all storage offerings, including EMC storage resold by Dell.

The tiered storage service will categorize high- and low-priority data to different storage levels to help a company cut costs.

The price and size of the services will be proportional to the size and complexity of the environment, Kaeley said.

Part of Dell's effort to "simplify IT," the service upgrades reflect Dell's push to reduce IT maintenance costs via customized hardware, software and services. Dell has acquired companies such as MessageOne and Everdream to boost its remote management portfolio.

Dell has also been under increased pressure to improve its service offerings in the wake of HP's acquisition of services company Electronic Data Systems in May. Analysts have said that EDS gives HP a leg up over Dell in the global services market.

Through its services, Dell does not want to send consultants to sit on a client's site for months only to create a 600-page report, Kaeley said. Dell intends to customize services and solve problems quickly through speedy data collection and reporting, Kaeley said.

Dell simplifies blade server management with I/O virtualization

Dell is releasing an I/O virtualization tool for its blade servers, making it easier for IT managers to install new blades and swap out servers.

Without I/O virtualization, IT shops have to manually assign Media Access Control (MAC) addresses and World Wide Name (WWN) identifiers each time they put in a new blade server. Dell's FlexAddress, announced Tuesday, abstracts the MAC and WWN addresses from the blade hardware, instead tying the identifiers to slots within Dell's PowerEdge M-Series blade chassis. (Compare blade server products.)

"FlexAddress is like a life insurance policy against downtime," says Rick Becker, Dell's vice president of solutions.
Rivals IBM and HP already have I/O virtualization tools for their own blade servers. HP released Virtual Connect in February 2007, and IBM announced its BladeCenter Open Fabric Manager in November 2007.

Dell is competing most directly with HP, because both vendors rely heavily on the x86 architecture, says Charles King of the Pund-IT analyst firm .

The significant aspect of Dell's FlexAddress is that it will "work with most any I/O switch, including Brocade and Cisco," King says. "With the HP I/O solution, both the Ethernet and Fibre Channel connectivity is done with a proprietary HP switch module."

Despite its proprietary switch, HP does claim Virtual Connect is capable of supporting "any industry standard" switch.

FlexAddress starts at $499. The product comes in the form of an SD card for the PowerEdge M1000e Chassis Management Controller.
