Considering that an average monitor has about 6-bit per channel color depth (8 bit minus the dithering), I guess 10-bit is for color proofing/professional DTP/digital cinema. And higher than 8 bit per channel has another challenges: Video card: the video card needs to support color outputs more than 8 bits per channel. Considering that DVI supports only 8 ...


If I am understanding you correctly, it sounds like you are taking a photo with the aperture set to less than the smallest f/ number possible for the lens. When you use a smaller aperture (larger f/number) then the image is darker and the depth of field is bigger (resulting in a sharper background). When you look through the viewfinder, the aperture is ...


In order to use the rear LCD to compose pictures (as opposed to using the optical viewfinder), you must put your camera into "Live View" mode. On the 600D, this is done by pressing the button marked with a camera icon and a red dot which is just to the right of the viewfinder: It is worth noting that using the rear LCD rather than the optical viewfinder ...


You can't, you can see why with a simple experiment: Walk into a very well lit room, set the camera to aperture priority (Av) and select reasonable exposure values (for example, f/5.6, ISO 400) also set the camera to capture raw files Turn off all the lights so that the room is fairly dark, take a picture of one of the walls (if you don't have a tripod it ...


The JPG image embedded in the NEF file is just one way of interpreting the raw information to make a final picture. It is the automatic conversion done in the camera. This is the conversion used to show you what the picture looks like on the monitor in the camera. They have to pick something. Nikon also encrypts the information so that you can't do the ...


In general, most camera LCDs are much higher contrast and much higher saturation than a general purpose computer monitor. They are tweaked this way because it makes the images look more vibrant on a small and low resolution display, but without more careful adjustment, they would look very artificial on a larger, higher resolution display at the same ...


As put in the comment, the colored halo is moire (helped a lot by the RGB pixel of the screen that plays havoc with the the Bayer filter in the camera). The distortion seems a combination of normal wide angle lens distortion and a non perfectly parallel camera/screen position. You can avoid all this by taking a screenshot of your desktop (OS dependent; ...


When you open the embedded jpeg most applications will render it the same because it is already in a standardized format that includes specific instructions on how the data should be displayed. The RAW data in your NEF file has already been converted by the camera based on either the default settings or whatever settings you have selected before you took the ...


This is obviously not normal operation, and neither should you debug yourself. Get a Nikon technician and have him fix this.


There are two main reasons why the viewfinder image may look different from the result: You are using a small aperture when taking the photo, but when you look through the viewfinder or on the LCD display the aperture is always wide open to let in as much light as possible. You are using a large aperture when takting the photo, but the viewfinder limits ...
