Saturate it with white vinegar , let it soak for at least an hour and then pressure wash it or scrub it with a stiff brush. Any stubborn stains can usually be removed with straight peroxide. Hope this helps...

How do I set the settings to take a night moon shot?


Assuming you mean pictures of the moon itself and not a night shot with the moon in it, set your camera to the manual exposure mode and ignore the light meter.

There's an old rule-of-thumb called the "Sunny Sixteen Rule." This states that the proper exposure under a midday sun is an aperture of f/16 and a shutter speed of 1 over the ISO. For example with an ISO 200 film or a digital sensor set at ISO 200 the proper exposure is f/16 and 1/200 second.

What does this have to do with night shots of the moon? Well, the moon is simply a large piece of rock under a cloudless midday sun. Thus the Sunny Sixteen Rule gives you a starting point for the exposure. You can then refine it by reviewing the picture on the LCD and looking at the histogram. The sky will go completely black and you won't see any stars, but you should be able to see at least some of the features of the lunar landscape.

Camera settings to shoot the moon


The best way is to set your camera to manual exposure and ignore the camera's light meter. The light meter will try to make the entire scene a middle gray, which will result in a gray sky with a blown-out moon.

There's an old rule-of-thumb called the "Sunny-16 Rule." This says that the proper exposure for a picture under a bright sun is f/16 at a shutter speed of 1/ISO seconds. So if you're shooting a daylight scene at ISO 200 then the proper exposure would be f/16 at 1/200 seconds or equivalent (such as f/11 at 1/400).

Why is this relevant? The moon is simply a large rock essentially at the same distance from the sun as any other landscape you've photographed. So start with f/16 at 1/ISO. Take a look at the result on the back of the camera. The sky will be completely black, but so what? It's the moon you want. Zoom in on it and see whether it looks the way you want it to. Adjust the exposure if necessary. Don't let it blow out to complete white.

I live in the Florida Keys and going to try and take some photos of the supper moon tonight. What settings do you suggest for a Sony SLT-A55V. I tried to use my longer lens last night without a tripod...


Take you camera off the automatic exposure setting. Left to itself, the camera will try to make the black sky a middle gray. You want to treat the moon as a landscape under noon sun. If you think about it, that's all it is. The moon is simply a large rock or mountain, lit by the same sun you get at noon. This is where the "Sunny-16" rule comes in. The proper exposure for a full moon is an aperture of f/16 and a shutter speed of 1/ISO. For example, if your ISO is set for 200, the shutter speed should be about 1/200 second. Any equivalent exposure will work as well, for example f/11 at 1/400. You can then review the picture on your display and adjust accordingly. The sky will go pure black, but that's okay. You're not taking a picture of the sky, but of the moon.

Can not take a picture, setting are not correct


Digital cameras allow you to take pictures at different quality setting. The higher the setting the better the photo quality. Higher settings use more memory then lower settings. If you intend to make prints, always use a medium or high setting. The low setting should only be used when all you want to do is view the pictures on your computer or send them by email or over the Internet.

Recommended camera settings for portraits:
Focal length: 100 mm
Aperture: F2.8 (as large a f/stop as is available for proper exposure)
Exposure / Shooting Mode: Aperture Priority / Portrait
Flash: Fill-in, if face is in shadow

Recommended camera settings for landscapes:
Focal length: 38 mm
Aperture: F16 (as small a f/stop as is available for proper exposure)
Exposure / Shooting Mode: Aperture Priority / Landscape
Tripod: Yes, for long exposures
