Nikon D50 SLR Review
By Movable Type Admin
The NEF (Nikon Electronic Format) file format is the digital equivalent of a film negative. It allows for extensive non-destructive editing and preserves the integrity of the original RAW image data. A NEF file consists of three key components that include raw image data captured by the imaging sensor, thumbnail images of the raw data, and a unique instruction set that retains camera settings from the moment a picture was taken. During post-production in Capture 4, these original camera settings can be tweaked, edited and saved as a variation of the instruction set, thereby leaving the original raw data unaffected, yet achieving the effects of the editing on the final image.
When shooting in NEF mode, all Nikon digital SLRs capture 12-bit images, instead of 8-bit in JPEG and TIFF modes. In Capture 4 these 12-bit images are processed into full 16-bit images using advanced algorithms, offering tone and color enhancements with the smoothest gradation and fidelity. Using Capture 4, a 16-bit NEF image can be easily transformed into a JPEG or TIFF. NEF easily replaces all other file formats as the ultimate image archive file.
Nikon Capture 4 is included in the D70S package and operates
"try it before you buy it" mode for 30 days.
It can also be downloaded from the
Nikon USA web site for both Windows and Mac users.
Nikon Capture Editor's window gives you quick access to the image
information and tools you need to get the most out of your NEF
files. The shooting data can be displayed across
the top or hidden to give you more image preview area. On the left is the
Quick Tools palette. The major editing
tools are organized in two palettes consisting of drop-down/expanding
sub-menus. Image adjustments are shown in realtime on the preview screen.
You can toggle the display of the tool palettes by pressing the TAB key.

Tool Palette 1
Color Balance - The Color Balance palette offers simple controls for adjusting overall brightness, contrast, and color balance for the entire image.
Unsharp Mask - The Unsharp Mask increases the contrast of the edges in the image while leaving other areas untouched. The amount of sharpness is determined by three factors: intensity, halo width, and threshold.
Digital DEE - Digital DEE (Dynamic Exposure Extender) reveals details in shadows and highlights, correcting for underexposure in back-lit subjects or shaded areas of images and for overexposure in brightly lit areas.
Color Booster - Enhance the color balance and saturation based on People or Nature, variable amount from 0 to 100 or Auto setting.
Size/Resolution - The Size/Resolution palette is where you specify the final "output" size of the portion of the image that will be saved.
Bird's Eye - The Bird's Eye windows show you what portion of the overall image you are viewing in the image preview window.
Information - The information palette shows the position and color of the pixel under the mouse pointer. The Information palette can also monitor the red, green, blue, and average values (R, G, B, Avg) for up to four selected pixels.
Tool Palette 2
White Balance - Correct the image's white balance by preset (Daylight, Flash, etc), introduce a cold or warm cast, specify the desired color temperature or sample the image for the gray point.
Noise Reduction - Attempts to minimize digital "noise" in images caused mainly by using high ISO sensitivities. It can reduce noise along the edges in an image, making outlines more distinct. With the D70 it is also very effective at removing or minimizing color moire patterns with the Color Moire Reduction option.
Image Dust Off - Compares a RAW image with a reference image created with the same camera to reduce the effects of any dust that may be present on the low-pass filter protecting the camera's imaging sensor. It only affects relatively featureless areas of the image.
Vignette Control - Correct for loss of marginal lumination, a phenomenon associated with camera lenses that causes a drop in brightness at the edges of a photograph. Most effective when performed on images taken at maximum aperture. If the image was taken with a type G or D lens, Nikon Capture 4 will use the lens information recorded with the image to automatically select an optimal value for Vignette Control.
Fisheye Lens - Modify images taken with an AF DX 10.5mm f2.8G Nikkor fisheye lens to resemble images taken with a normal wide-angle lens. This option is not available with other lenses. See examples below.

Camera ControlUsing the Camera Control component of Nikon Capture, you can control almost all aspects of camera operation remotely via USB port from your computer. If Camera Control is running when a D1-series camera is connected, pictures taken with the camera will be stored on your computer hard disk, not the camera memory card.
The camera can be operated either directly or by using the
controls in the Camera Control window. Camera settings are displayed in
Camera Control. As photographs are captured, Nikon Capture Camera Control can
automatically process the images to reflect image adjustment settings in
Nikon Capture Editor.
Camera settings can be controlled from both the computer or from the camera if the "enable controls on the camera body" box is checked. The "Exposure 1" page shows the exposure mode, shutter speed, aperture, exposure compensation, flash compensation and the flexible program shift (if applicable.)
The status line on the computer screen is almost identical to that found inside of your camera's viewfinder and changes in realtime to reflect current camera settings.
Just click on the "AF and Shoot" button to have the camera perform autofocus and then
capture the picture or click the "Shoot" button if already focused or using manual focus.
The "Exposure 2" page lets you choose the AF area, metering mode, flash sync mode,
ISO speed and white balance.
The "Storage" page has options for saving the captured image as JPEG or RAW or
RAW + basic JPEG, if JPEG then you can also select the compression level desired,
and image size.
The "Mechanical" page lets you select the drive mode, AE bracketing and AF mode, it
also indicates the lens being used and the battery level.
The "Image Processing" page lets you do some post-capture pre-save image massaging
such as sharpness, tone compensation, color space, saturation, hue adjustment and
enabling noise reduction.
The "Status" screen pops up after an image is captured and shows a preview thumbnail and lets you know how much space is left on the host computer's drive, where the image was saved and can also display an optional histogram.
You can take a series of time-lapse photographs automatically.
