When shooting with flash in a location where there are many suspended particles, such as in a dusty area or on a snowy day, the image may contain white circles as shown in the picture below. Why does this happen? If the flash fires when a suspended particle floats right in front of the lens, the reflection of the flash from the particle appears more intensely than that of the subject, as the particle is much closer to the lens than the subject. Therefore, the reflection of the flash turns out in the image and causes an effect such as that shown in the sample image above. The closer the lens and strobe are located, allowing suspended particles to be exposed to more light, the more frequently this effect can occur. How can I avoid this effect? Ideally, it is best to shoot in locations where there are very few suspended particles. If not, you can use following method to prevent this effect. a) Avoid using flash by lighting the area as much as possible. b) If your camera has a zoom function, shoot at a wide angle. c) If you can attach an external flash, use the external flash to distance the flash from the lens.

Just got a Fuji Finepix AX200 for Xmas, we are seeing spots in our pictures - possibly some type of ghosting. How do we correct this?


Ghosting, spots, a series of circular colored hazy anomalies are called lens flair. It happens when a point of strong light source crosses the lens at an angle. Your pictures may have been in a room with a table light to one side or even an over head light. It will happen outdoors when you are shooting into the sun or an angle to the sun. Shooting a lighted Christmas tree will cause numerous possibilities of lens flair. The only fix is to shade the lens either with a lens hood your hand or in my case i sometimes use my hat. Pro cameras and their users fight with this problem on many occasions so it's not because you have an automatic camera.

I have a new stainless steel stove which now has brown burnt spots on it. How can I get the original shine back.


A really good stainless steel polish and some ultra fine sand paper or a sanding sponge should do the trick to remove the burnt spots. Use very light pressure in a circular motion to remove some of the surface area of the stainless steel to remove those stubborn spots. Then finish off the rest with the polish.

I have rust spots on textured refrigerator door I have no rust spots on the freezer door, what is the cause and how can I clean it? It is a wirlpool...


I do not yet know the cause, but I do know how to clean it up fairly well. You will need a rough surfaced rag or sponge, some additional clean rags, regular dishwashing liquid and baking soda. Dampen the rough surfaced sponge, cover with a layer of the liquid soap, then a layer of baking powder. With this, clean an area of the rust using a circular motion. You will need to rinse and reapply the cleaning agents often. You will see the brown rust coming off a little more with each cleaning. Use additional rags for rinsing the whole area. I spent an hour on the fridge side door before I was satisfied. The unit is in a vacation rental that probably is not always well temperature controlled. It is also a Whirlpool leather look textured door.

Dark circular spot on Ricoh R6 screen and images


There is a spec of dirt that made it inside the camera and has landed itself on your image sensor.

If you take a picture and the image has a spot on it, it could be the screen. If you transfer it to your computer and the spot is in the same spot, its something on the image sensor. You would have to send it out for cleaning, and a new camera would be cheaper.

Spots on screen


Youlikely have dust inside the optical block on the LCD panels. Cleaning the panels is a tricky job and just shooting compressed air into the block will only redistribute the dust. A qualified tech can disassemle the block and clean the panels

Spots on Rebel XT image


Dust is something that will need to be addressed. Get a Visual Dust brush and learn how to use it. You can help reduce dust by 1) changing lenses with the camera body facing down and 2) turning off your camera when changing lenses.

Spots on image when using built-in Speedlight flash


As is common in many compact digital cameras where the built-in flash is very close to the lens strange reflections can appear in images under certain conditions. Particulate matter in the air in front of the lens (between the camera and subject) such as water vapor (as in a cloudy day), smoke, dust or other items can reflect light directly into the lens causing neutral colored white/grey semi-transparent spots to appear in the image. In extreme examples there may be many of these spots in an image or there may be only one per image. Also, since these spots are completely random they will move or disappear from image to image. For example, if two images are shot consecutively with the same camera settings one image may have spots while the other is clean. To avoid these spots: When possible, avoid photographing in smoky, dust, or cloudy areas Do not use the camera's flash in locations such as above Use an external Speedlight flash if a flash is needed Review images on the camera and re-shoot if spots are visible Cleaning the lens will not have an effect on these spots, as the particles that cause this are not on the lens itself.
