This can be eliminated with the use of a hollow pipe, attached to the camera lens, which intersects the sea surface such that a picture of light upwelled from beneath the surface is obtained. Used in this way, linear relations between both the ratio of red/green digital output (O/P) ...

The lower plot is the color error, measured as ΔCab(geometrical distance in the CIELAB a*b* plane), ΔC94, and ΔC2000. They are quite close because chroma tends to be quite low for grayscale patches. Lens flare (stray light that bounces between lens elements and off the barrel) can...
Appears as a gradual and often subtle darkening away from the image's center. Caused by the inner workings of your particular lens and camera. It's typically most apparent at lower f-stops, with zoom and wide angle lenses, and when focusing on distant objects. Digital SLR cameras with ...
Technology is improving all the time, and the key to getting a good shot with a mobile device is to keep your phone as stable as possible. If you are looking for a clear image of the moon, you will need to invest in one of the best cameras for astrophotography. With a quality lens...
but is also a big problem for long exposures with heavier SLR cameras. Try attaching a big lens to your SLR camera and facing it horizontal on your tripod. Take an exposure of around 30 seconds if possible, and see whether your image has slight motion blur when viewed at 100%. Pay part...
