-Ghost images - bright spots of light, often taking the shape of the aperture, which appear in the camera viewfinder or in the final photograph when a lens is pointed at a bright light like the sun.
Ghost images or images of the diaphragm have much more to do with the design of the lens than with coatings, although coating will reduce the effect when it is present. I have several old, uncoated lenses which do not produce ghost images.
Ghost images and lens flare.
Bright spots of light, often taking the shape of the aperture, which appear in the camera viewfinder or in the final photograph when a lens is pointed at a bright light like the sun; ...
Indoors, where there is little existing light, you have no problem because the electronic flash itself stops the action; however, outdoors in daylight, you may encounter ghost images.
Using high speed flash for my background coverage and 1/200 of a second for my shutter speed eliminates the possibility of ghost images. All of this can be accomplished with TTL flash metering for all three flash units.
Lens hoods protect the front element from bumps and keep stray light from striking the front of the lens and causing flare or ghost images.
Caps protect the front and rear of the lens when it's not in use.
Normally, you should hold the camera stationary so you are not creating camera motion problems to go along with ghost images, but with some particularly fast critters you may consider "panning" with the motion.
Things such as fruit dropping in water and ghost images are likely to be of intense interest to the photographers this book will most help.
Flare is a general description of a variety of ghost images, colour spots, halos and haze that appear in the final image and in many cases is a result of a direct sunlight or other strong light hits directly the front element of your lens, ...
The X100's flare characteristics tend to be most obvious (and, depending on your point of view, problematic) when shooting in low light or at night, which is when flare patterns and ghost images can become most visible against dark backgrounds.
The depositing of multiple coats of anti-reflective materials on a lens surface to reduce ghost images and flare produced by internal reflections and insure faithful color rendition; in the Nikon Integrated Coating system, ...
dehaze
the removal of ghost images from a reclaimed screen.
dehydration
the loss of water from a sheet of paper from exposure to high-temperature, low-humidity air, or both.
When you look through the viewfinder at a bright object you'll see two dim ghost images. Adjust the focus until the images overlap, then remove the cardboard. You'll probably need to experiment with hole size and placement for this to work well.
Lens hood
A short conical shaped tube that attaches to the front of a lens to shield it from extraneous light. Helps prevent lens flare, ghost images and loss of contrast. An inexpensive must have accessory for your camera system.
Camera shake occurs while the shutter is open and exposing the film. If there is any movement, it will show up as motion lines and ghost images. This often happens in low light, with longer shutter speeds needed to expose the image.
The LW46 18MM wide angle lens for LX3 is much better than the 24mm LW55 lens for FZ50/FZ30, less barrel distortion, and far less flare and ghost images. The following are test shots with LX3+LW46: ...
if you have an extreme reduction of the resolution settings, typical JPEG-effects will become visible: where the colors change only in small steps, the picture will resolve in square compression blocks, while in high-contrast contours 'ghost images' ...
