All about the amazing digital camera reality

Lighting and colors are important points. When using your digital camera, you might as well explore with a manual mode. Sometimes, you may need to change settings. When this happens it is important to know what to do, to identify if what you see is really dirty on the sensor, the lens or lens or viewfinder of the camera. If you want to learn how to handle this situation, read on.

Sensor cleaning

When there is dirt or particulate on the sensor is manifested as a mild and slightly dark stain on light areas like the sky blue or sea water. The appearance of these spots can vary depending on the nature of the particle, its shape and exposure parameters but should seem rather to show you the image below.

Particles of dust may sit on top of the digital camera sensor, a thin film that serves to filter out ultraviolet rays to protect the sensor. Because the particle is separated from the sensor for this film is projected depending on how well the sensor will be diffuse or defined the particle in the picture. This is why the opening affects your appearance in the photo. A large aperture (small f number) the particle tends to be more diffuse because the light reaches the sensor from wider angles with small openings while the particle is more definite.

Through the viewer, you can identify what is going on. If the particle is located in the viewfinder or on the viewfinder screen this will not affect the image! So if you see the particle in the picture is definitely not in these two places are situated.

If the particles are present in the glass front or rear of the target they impact the quality of your photos. Identify the digital camera location of these particles requires some tricks. First change the lens of your camera to another to see if there are spots in the picture. Such stains are often larger than those produced by a sensor and are higher in small apertures like f/22.

If after the first two tests you do not identify any source for the spots, it is very likely then that are produced by particles on the sensor. The best known method is to point your digital camera at a clear and smooth surface so that it fills the frame. You can use a white paper or a white wall. I have had excellent results doing it with a light gray surface.
