Camera and lens maker Sigma has bought Foveon, the sensor technology company that develops the sensors it uses. Foveon’s technology uses three photosensitive layers to detect red, green and blue light at each pixel. Sigma says owning the company will allow the development of new types of sensors and improved integration between the sensors and its lenses

 

Nikon is pleased to announce the introduction of an all-new FX-format digital SLR: the 12.1 megapixel Nikon D700, designed to enable many more photographers to enjoy the acclaimed image quality of the Nikon D3, but in a smaller form factor.

”The Nikon D3 has taken the action photography industry by storm, motivating many pros to change brands and we expect the D700 to contin5ue that trend,” said Robert Cristina, Manager Professional Products and NPS at Nikon Europe. He added: “The D700 excels in the extreme low-light and high-contrast conditions under which today’s cameras are judged and affirms Nikon’s ongoing commitment to meeting tomorrows imaging needs too.”

D3 DNA

The D700 inherits the ‘must have’ image quality of the D3. Using the same core technologies such as the highly-sensitive 12.1 effective megapixel CMOS image sensor with large pixel pitch and gapless micro lens array that affords bright, clean files across a broad ISO range. The D700 also features the same innovative EXPEED high-speed image-processing system, 14-bit A/D conversion and 16-bit processing pipeline to provide the detail and smooth gradation necessary for outstanding print enlargement and reproduction.

FX on the move

The D700 is ideal for those seeking a perfectly-balanced DSLR on the move, without compromising durability or environmental resistance to moisture and dust. The D700 incorporates an image sensor cleaning system that uses high frequency vibrations to reduce the accumulation of dust on the image sensor surface. A responsive 5fps is possible with the compact 1500mAh EN-EL3e lithium-ion battery, with up to 8 fps possible by attaching the optional MB-D10 battery pack to use the powerful 2500mAh EN-EL4a battery if desired. This offers complete power supply integration for those already using the D3 and D300. Another first is the practical i-TTL built-in pop up flash with 24mm lens coverage, ideal for discrete flash lighting when a full size Speedlight might be too cumbersome.

Getting the shot right

Despite its attractive price tag, the D700 makes no compromises in its comprehensive feature array with a highly responsive shutter release time lag of just 40ms, the acclaimed accuracy of the 51-point MultiCAM3500 AF system, DX Crop Mode and Live View with contrast-detect AF displayed on the same high-definition 3-inch TFT monitor used on the D3 and D300. One of the most important advantages of FX format cameras is the viewfinder experience and the D700 features an outstanding solid glass pentaprism, 95% coverage and adjustable AF point LED illumination for a bright, uninterrupted view. A clever new feature is the ability to display the Virtual Horizon level indicator during Live View mode to determine camera orientation at arms length.

What NIKKORS have been waiting for

The D700 is designed for the future without ignoring the past. As Nikon celebrates the 75th anniversary of the very first NIKKOR lens, and with well over 40 million sold, intelligent image processing technologies to control peripheral illumination (Vignette) and chromatic aberration enable photographers to rediscover the creative possibilities of their existing NIKKOR F mount lenses. For newcomers, the ever-expanding Nikon Total Imaging System provides lenses, Speedlights, Software and accessories for every photographic challenge both now and in the future.

The D700 is supplied with battery EN-EL3e, charger, and Nikon Software Suite and will go on sale from 25 July 2008 with a MSRP guide price of €2599.

 

Sony is preparing a new leap for digital SLR cameras as it has manufactured a 35mm full size 24.81 megapixel CMOS image sensor. To drench the thirst of future SLR owners the new image sensor had to use several new technologies like advanced planarization for minimizing fluctuation and the “Column-Parallel A/D Conversion Technique” which provides each column within the sensor with its own A/D converter, minimizing image degradation caused by the noise that arises during analog processing.

This 24.81 MP sensor is set to enter mass production later this year.

 

The EXILIM Pro EX-F1 incorporates a new high speed CMOS sensor and high speed LSI processor. After building in 6.0 million effective pixels and a 12X optical zoom, the developers focused on achieving a burst shooting speed capability that was hitherto unheard of. Using the camera’s ultra-high speed burst shooting for still images or its high speed movie recording mode, users can capture a split second’s movement with greater detail than before, allowing them to catch each decisive moment, and even motion that the human eye cannot ordinarily perceive.
*As at January 6, 2008, based on a Casio survey for the consumer market digital cameras.

Full resolution photography using 60 fps ultra-high speed burst mode captures the crucial moment
Using the still image burst mode, users can shoot at an ultra fast 60 frames per second. In burst mode, the frame rate can also be varied from between 1 and 60 frames per second while shooting. Up to 60 shots can be taken at once, so 60 shots per second for one second, or 5 shots per second for 12 seconds, are possible.

Don’t miss that crucial moment, Prerecord Still Images, using ultra-high speed burst function
Users can record images not just at the instant they press the shutter button, but before! Continuously recording at up to 60 images per second, a maximum of 60 images can be saved in the camera’s own buffer memory even before the shutter button is depressed. Even if users press the shutter a little late, they will still be able to catch that vital moment.

Slow Motion View function lets users view and capture that critical moment in slow motion during still photography
Users can take photographs while, in the monitor, the momentary action that is before their eyes is displayed in slow motion. It is just as if they have slowed down the passing of time. Users can unhurriedly observe the motion of the subject as they press the shutter, ensuring that they never miss that crucial moment.

Rapid Flash function allows continuous shooting even in low light
It is possible while using flash to take up to 20 continuous shots at a speed of up to 7 frames per second, so even in low light, no more missed shots. Also, the internal LED light allows high speed burst shooting at between 10 and 60 frames per second.

High speed movie recording at up to 1,200 fps
The EXILIM Pro EX-F1 can record high speed movie footage of motion too fast for the human eye, for ultra slow motion playback. Users can select a recording speed of 300 fps, 600 fps or 1,200 fps. There is also a Movie Button that lets users quickly start movie recording without first switching from still image mode.

Full High-Definition movies
The camera features Full High-Definition movie recording capability. Users can record beautiful movies at a screen size of 1920×1080 pixels, at a rate of 60 fields per second. The camera can be connected to an HD compatible television with a separately available HDMI cable to enjoy viewing movies.

 

To answer it you need to know two things, the size of the print you need to make and the resolution that your printer needs for the best results.

The size of the print is simply however large your printer can handle. The resolution that your printer needs may be a little trickier to figure out. Resolution is the density of the pixels for a given distance, usually measured in pixels or dots per inch. Most modern inkjet printers print anywhere from 1200 to 4800 dots per inch (what the printer manufacturers really mean is 1200-4800 droplets of ink per inch). Inkjet printers use many tiny round droplets of relatively few, 4-8 ink colors to reproduce one square pixel in your image that could be any of millions of colors. A common mistake is to set the resolution of the file to the resolution of the printer. In all but a few special printers this will result in huge files that will not print well, if at all.

The secret is that the human eye can not see much more than 250-300 pixels per inch. So the ideal resolution for your files should be close to this and be an even multiple of the printers resolution. See the chart below for recommendations on resolution settings for common printers.



Keep the proportions in mind because the proportions of films, digital camera sensors and papers can all be different. For example most digital cameras sensors are proportioned so that the height is two thirds the width or 1:1.5; While the most common paper size, in the US, is letter which is 8.5×11 inches or a about 1:1.25.

These kinds of proportion mis-matches are common and require that the original image be cropped to fit the proportions of the paper size. If your image cannot be cropped without ruining the composition then you will need to adjust your print size to longer dimension.
