The FujiFilm FinePix F11 Zoom looks and feels identical to F10. There F11 is more or less a premium version of the F10 and offers a few improvements: resolution of the LCD monitor has increased to 153,000 pixels (F10:115,000 pixels) and an improved macro mode performance that makes it possible to take crisp, clear shots of subjects as close as 5cm (F10:7cm). It also now includes A (aperture priority AE) and S (shutter priority AE) modes, and the 256-zones metering enables more precise AE for a variety of a scene. Compared to F10, it appears to be faster. The most important thing remains: with the basic functions of the FinePix F10, including Fujifilm’s innovative Real Photo Technology (produces natural results without having to use the in built flash) and Super CCD sensor, the new Fuji FinePix F11 incorporates manual shooting functions, such as aperture and shutter priority settings.

Sony’s first camera with wireless capabilities is the Cybershot DSC-G1 was released in 8 March 2007. With just a touch of a button you can instantly and wirelessly send your photos to a DNLA (Digital Living Network Alliance) compatible PC or another camera. The 2GB internal memory capacity (stores up to 7,500 VGA-quality or 600 6-megapixel photos) means you will not need memory card storage for your photos. The G1 also has a different design approach than other Cyber-shot cameras. It’s bigger and thicker than most, “with a curious wedge-shaped design that fits somewhat oddly into the hand”. Sony’s Super Steady Shot is the optical image stabilisation by Sony for steady and sharp, crystal clear photos. Like all other Sony digital cameras, it is based on Carl Zeiss lens, but, you slide the lens cover across, instead of down as with previous models, and you’re ready to shoot in less than a second.The Cybershot DSC-G1 is expected to be in shops starting April and will be available for purchase at a start price of $600. I’m looking forward to find out more about this camera’s image quality capabilities.

The FinePix F10 has a metal body and a design which makes it not very slim but quite compact. The controls are well placed and it is easy to use. Other features: Calendar view, Voice memos, DPOF, Autofocus Illuminator, PictBridge and USB connectivity. As for the image quality, this digital camera provides good colors and sharpness, good white balance and no barrel distortion and amazing little noise at high ISO. The movie mode performs very well too. However, it lacks the Aperture and Shutter Priority modes as well as manual controls. This is quite sad for a camera with such a great performance of the picture quality. The battery consumption is low, so this is another reason to choose it as your point-and-shoot camera. No image stabilisation and no viewfinder.

In Black & White Photography, the shapes, the structures and the contrast gain importance.
You can shoot directly in BW on most of the digital cameras, and some of them (Canon EOS) even come with some software filters to control the contrast (red, orange, yellow). The disadvantage of shooting BW is that you can not have that picture in colors if you change your mind and in most cases you can’t apply color filters before BW conversion.
By shooting in RAW mode you will obtain a lively BW Photography. Why? Because raw format offers more detailed grey tonalities. Some RAW converters have the BW option incorporated.

For TIFF and JPEG there are many possibilities to convert in BW. The chosen method depends on the desire to influence the grey tonalities during the conversion.

Method 1 – Desaturate !

The simplest solution is the “Desaturate” option in Photoshop, in the “Image”->”Adjustments” menu. This way, there is a high probability that some information of the image will be lost.
Black and White Conversion

Method 2 – Saturate to -100 !

The second choice in Photoshop is to reduce the saturation to -100 (same Image -> Adjustments menu).
Black and White Conversion

Method 3 – Change Image Mode !

The third method in Photoshop is to transform the RGB mode to Grayscale (or Duotone in case you want some color tint). By confirming “Discard Color Information”, the image is reduced to BW. Same thing would be this: the mode “Multichannel” with Grayscale activated contains all the BW information.
Black and White Conversion

The “Secret Method” – Use this BW Conversion Plugin !

A more complicated but far more flexible and with better results, it’s the conversion using a Photoshop Plug-in. There are many out there on the internet, but I like B/W Conversion from Photo-Plugins because it provides all kind of filters in different tonalities. More than that, it offers full control over each color channel and gamma, as well as some preset configurations: Linear, Photoshop, Agfa, Kodak. It even provides a very good grain function (some photographers enjoy BW with some grain). After the conversion and before applying the changes, the plug-in offers a tone option. This will give sepia, bluish or whatever color tone you wish to the picture, more or less visible.
Note: All your Photoshop plug-ins are under the Filter Menu.

Black and White Conversion Black and White Conversion Greed Filter
The following example shows how I first applied a red filter, and after the conversion, with some contrast/brightness adjustment, the initial red color will appear as white.
This is how i get the white insted of redBlack and White Conversion - red filter

After the conversion, it’s a good idea to give the picture more contrast, but be careful not to burn the image. Keep a good balance between the details and the contrast: the bigger the contrast, the less details in the image; and if there is too little contrast, the less impressive the image.

Other photo editing software have similar solutions (another good example is Picasa where the BW conversion is extremely simple: just press a button that offers a BW preview).

Focal Length

The focal length of a lens determines its angle of view, and also how much the subject will be magnified for a given photographic position.

Focal length also determines the perspective of an image.

Longer focal lengths require shorter exposure times to minimize burring caused by the shake of hands.

The Focal Length means how much can your camera see.
focal_length2.jpg

focal_length.JPG

Aperture



The aperture range of a lens refers to the amount of light that the diaphragm can let inside the camera to reach the sensor.

Apertures are listed in terms of f-numbers (expresses the diameter of the entrance pupil in terms of the effective focal length of the lens; It is the quantitative measure of lens speed), which are marked on the lens.
On a camera, the f-number is usually adjusted in f-stops.
Each “stop” is marked with its corresponding f-number, and represents a halving of the light intensity from the previous stop. Modern electronically-controlled interchangeable lenses, such as those from Canon and Sigma for SLR cameras, have f-stops specified internally in 1/8-stop increments, so the cameras’ 1/3-stop settings are approximated by the nearest 1/8-stop setting in the lens. The F number can be displayed as 1:X instead of f/X(like in our example).
Aperture
lens_example.jpg
Lenses with larger apertures are faster because, for a given ISO speed, the shutter speed can be made faster for the same exposure. A smaller aperture means that objects can be in focus over a wider range of distance (depth of field).

Portrait and indoor (sports and theater also) photography often requires lenses with large maximum apertures in order to be capable of faster shutter speeds (and narrower depth of fields) in order to combat the low light problems with no camera shake.
The narrow depth of field in a portrait, as well as in macro photography, helps isolate the subject from the background.
Aperture
Minimum apertures for lenses are almost as important as maximum apertures. This is primarily because the minimum apertures are rarely used due to photo blurring from lens diffraction, and because these may require long exposure times.

For cases where extreme depth of field is desired, then smaller minimum aperture (larger maximum f-number) lenses allow a wider depth of field.
It’s also good to know that lenses typically have fewer aberrations when they perform the exposure stopped down one or two f-stops from their maximum aperture.
