清洁数码相机

清洁数码相机
Clean Your Camera

The lens is your digital camera's window to the world. It must be kept clean and scratch-free, or your photos will suffer.

If you have a high-end camera, the lens probably has screw threads, which means you can add a UV or Skylight filter (available at your neighborhood camera shop). The main purpose of this filter is to protect the lens from scrapes, scratches, bumps, and bruises. A filter only costs a few dollars, and you can replace it if it gets dinged.

Most inexpensive digital cameras don't have threads for filters. If your lens lacks screw threads, you need to be extra careful and remember to cover the lens whenever the camera isn't in use. If your camera has a built-in cover that closes whenever the camera is turned off, so much the better.

Regardless of the price of your camera, handle the lens elements as infrequently as possible. Even cleaning the lens in the wrong way can wipe away special coatings and increase the chances of a scratch.

清洁相机

镜头是你的数码相机面向世界的窗口。它必须保持洁净并且没有划痕,否则你照的相片将会受到损害。

如果你有一架高档相机,那么它的镜头上可能有螺旋纹,这表明你能增加一个紫外或者天窗过滤器(附近的相机店里有售)。过滤器的主要目的是保护镜头免受刮,划,碰,擦。一个过滤器只需花费几美元,并且如果坏了,也可以再更换。

大多数廉价数码相机没有为过滤器准备的螺纹。如果你的镜头上没有,那就需要特别小心,并且记得当不使用相机时要遮盖住镜头。如果你的相机有一个内置保护盖,当关掉相机时可以关上盖子,当然更好。

不管你相机的价格是多少,都应该尽可能少的触摸镜头元件。如果用错误的方法清洁镜头,即使能擦去特别的灰层,也增加了一道刮擦的机会。

So, here's how to clean it correctly. Depending upon how frequently you use your camera, every few weeks or months you may discover that the lens is dirty. Pick up a lens cleaning kit for just this purpose. Any photo store can sell you a good kit for just a few dollars. Start with a lens brush and a blower, or a can of compressed air, to remove loose-clinging, abrasive particles--you'll want to blow them off before you wipe the lens with a tissue. Then place a drop or two of lens cleaning fluid on some lens tissue or cloth and clean the surface in a light, circular motion. Don't put the liquid directly on the lens, and don't press hard with the tissue. Let the lens dry, use your blower to blast away any remaining dust or particles, then cap the lens.

You can use the same basic technique to clean the LCD viewfinder and the optical viewfinder. Because the optical viewfinder is small and recessed into the camera body, it can often be tricky to clean properly. Thankfully, you don't have to worry quite so much about scratching it, since it is neither quite so delicate nor as critical to taking good pictures.

因此,这里有怎样正确清洁镜头的方法。这决定于你使用相机的频率,是每隔几周还是几个月,你发现镜头会变脏。首先,为此要挑选一套清洁工具。任何相机商店都能卖给你一套好的工具,仅仅需要几美元。开始是一把镜头刷和一个吹风机,或者是一罐压缩空气,来除去松散附着的研磨剂状粉粒---你要在用薄纸擦拭镜头之前把它们吹掉。然后在一些镜头薄纸或布上滴一两滴清洗液,轻轻地作圆周运动来擦拭。不要直接把液体滴到镜头上,不要使劲压按薄纸。保持镜头干燥,使用吹风机吹掉剩余的其它灰尘或者微粒,然后盖好镜头。

你可以使用相同的基本技术来清洁LCD或光学取景器。因为光学取景器较小,并且凹进相机里面,所以合适的清洁方法经常是需要窍门的。令人欣慰的是,你不用过多担心可能会刮到它,因为它不是那么的脆弱,也不是拍好照片的关键。

I thought that finding minor corrosion on battery contacts was a thing of the past, but I recently encountered not one, but two different cameras in which the metal contacts had corroded slightly from long-term exposure to a battery. How do you get rid of such grime? With a $50 Battery Contact Cleaning Kit, you ask? No, with a pencil eraser: Gently "erase" the corrosion. But be careful, you don't want to remove the metallic coating on the contacts. Keep in mind that the eraser is a mild abrasive; that's how it can remove the corrosion. You can also blast dust and grime out of the compartment with your compressed air.

Finally, your memory card slot gets more abuse than nearly any other part of your camera. Always be sure that you're installing cards correctly. Never force them--doing so can break connections and ruin the camera. Also, store your camera with a memory card in place or, if you can't do that, at least with the memory card cover closed--that keeps foreign matter out of the slot and protects the contacts. If you need to clean the slot, never, ever, ever (yes, that's one never and two evers) insert anything into the slot that doesn't belong there. Something as innocuous as a cotton swap can bend one of the delicate electrical pins. If necessary, blast some compressed air into the slot to blow out any intruders.

我原来以为发现电池接触点小的腐蚀,是过去的问题,但最近却遇到了不只一次,有两个不同的相机,在金属接触处都有轻微的腐蚀,这是因为电池是长期的暴露着。你怎样除去这样的污点?需要50美元的电池接触点清洗工具吗?不要,只用一个橡皮擦:来轻轻地“抹去”腐蚀。但要小心,你不能用这样的方法擦除接触点上的金属薄膜。记住橡皮擦是适度的研磨剂;所以它能除去腐蚀。你也可以用压缩气体吹去零件间隔中的灰土和尘埃。

最后,和相机的其他几乎任何零件相比较,你的存储卡插槽的使用次数是最多的。要确保总是正确地插卡。决不使很大力气---否则会破坏连接点并且毁坏掉相机。此外,保存相机时要带着存储卡,如果你做不到,至少要保证存储卡的盖子是关闭上的---能防止外来的杂质进入插槽里并且保护接触点。如果你要清洁插槽,那么决不要,永不要,(是的,一次也不要)把任何不属于插槽的东西插进去。用一些象棉线圈般无害的东西,来弯曲成一个精美的电别针。如果有必要,把一些压缩气体猛的吹进插槽里,来赶走任何的入侵者。
