Problem: Write an article based on this summary: Try a UV filter to get rid of haziness in your photos. Get a polarizing filter to reduce glare. Use a neutral density filter to extend your exposure time. Control light gradients with a graduated neutral density filter. Use a close-up filter to zoom in further without losing focus. Change the white balance with a colored filter. Try a special effects filter to add unique shapes to the photo.

Answer: UV rays enter your camera’s sensor and create a haze on top of your photographs. UV filters with a higher intensity block more UV rays while filters with a lower intensity block fewer. Screw on a UV filter to the front of your lens to help block the rays and make your images develop clearer. You can keep the UV filter on your camera at all times if you want to, but it may make your photos look less sharp.   Film cameras are more sensitive to UV rays than digital cameras. You can also use a skylight filter for a similar effect in your photos. Polarizing filters reduce the amount of reflected light from a certain angle that enters your camera lens. The filter makes it easier to see into reflective surfaces, like water, and makes colors seem deeper and richer. Rotate the filter around the lens to see how it affects the light differently. Polarizing filters can decrease the contrast between land and sky when you take pictures with them. Neutral density (ND) filters evenly decrease the amount of light that enters the camera and makes it easier to take long-exposure photos. The filter keeps the shutter open for longer even when you’re using settings that wouldn’t normally allow long exposure times. Pick an ND filter if you need to take photos at a shallow depth of field in bright light or if you want to make moving objects less clear. The amount of light blocked depends on how strong of a filter you have. Filters that have a larger number will increase the exposure time longer. Graduated neutral density (GND) filters are similar to ND filters, but they allow more light through certain areas of the filter. Look for various GND filters with different gradient patterns to see how they affect your photo. Rotate the GND filter on your camera lens to see which side of the photo is lighter and which side is darker.  Pick a “hard edge” filter if you want abrupt changes in exposure and a “soft edge” filter if you want the exposures to blend together. GND filters are typically the least used since you can easily replicate the effect in an image processor. Close-up filters act like magnifying glasses and make the object you’re shooting appear larger. Close-up filters come in a variety of magnifications so choose one that works best for the type of subject you’re shooting. If you want to focus on photographing smaller details without them getting blurry, then screw on a close-up filter to your lens. A close-up filter may affect the color of your photo slightly and could leave digital artifacts on your photo. Colored filters usually come in warm and cool colors to affect the overall lighting of your photos. Use a warm filter if you have cool lighting and a cool filter if there are warm-colored lights. Once the filter is attached to the lens, the lighting will look closer to the true colors of the objects. Colored filters are less common since you can usually change the white balance on your camera or adjust the colors in a digital program on your computer. Special effects filters have many different designs that each change your photo in a unique way. Some filters may add vignettes or a foggy appearance while others may change how lights look when they aren’t in focus. Look at the effects of multiple filters to see which ones work best for you. Many effects you can get with these filters can also be done digitally on a computer.

Answer: It’s the blue circle with a white “A” inside. You’ll usually find it on the Dock. It’s at the top-right corner of the App Store. This opens the Facetime page on the App Store. It’s right below the app’s icon. Facetime will now download and install to your Mac. Once the download is complete, an “Open” button will appear. You can click that button to launch Facetime.


Problem: Write an article based on this summary: Notice if a sore doesn’t heal. Look for moles with color that spreads out from the mole. Check for redness and swelling around the mole. Notice tender, itchy, or painful moles. Check for changes in the surface of the mole.

Answer:
If a sore or pimple isn’t improving or continues to reappear in the same location, then it’s time to see a doctor. Your melanoma may look like a regular pimple or damaged skin, but you’ll notice that it doesn’t respond to typical treatment products. Melanomas sometimes look like the color is bleeding out from the mole into the other skin. For example, a red mole may have a pink area around it, or a dark brown mole may be surrounded by light brown skin. Also look for a purplish blue color in the blemish or mole. You may notice that one or more of your moles looks puffy or irritated, similar to a bug bite. This swelling is a symptom of a melanoma, so you should get that mole checked.  The swelling could be minute rather than a lump, so don’t dismiss a slightly raised area. The redness could be pink rather than a dark red. A melanoma will feel different from a normal mole. Use your fingers to feel your moles and the area around them to see if they feel sore or hurt. If a mole begins to itch, make a note of it. Keep track of how often it itches. If you notice the issue continuing for a few days, make an appointment with your doctor. The skin over your mole may undergo changes, even if the size and color stay the same. Your skin may feel scaly or develop a bump. You may also notice oozing or bleeding on your mole.
