Write an article based on this "Have your subject look at the lens or other fixed point. Examine the eye closely and decide what most interests you. Produce a catch light with a continuous light source. Get as close as you can to the eye. Use your camera's zoom to hone in on the eye. Keep your camera steady with a tripod or other sturdy surface. Set up a mirror behind your camera to take a photo of your own eye."
article: Having your subject look directly at the camera lens will help you take a detailed photo of their iris and pupil. If you want to capture the eye from a different perspective, have your subject look at a fixed point so you can find the best angle from which to take the shot. Are you drawn to the colors and patterns of the iris, or the reflection of the light on the pupil? Do you want to focus on the wrinkles around the eye, or the curvature of the eyelashes? Your answer to this question will be the main detail you focus on when taking your shot. A catch light is the small white spot you sometimes see in close-up photographs of the eye. You can create a catch light by setting up a stable, continuous source of light. You can use a softbox, an umbrella, a ring light, or natural light to create this effect. Make sure that your camera isn't casting a shadow over your shot. Many close-up shots of the eye don't turn out for the simple reason that the photographer didn't get close enough to the eye. Position your camera's lens as close your subject as it can be without your shot going blurry. Be careful not to block the light you need for your shot. Adjust your zoom until you find a viewpoint you like. Widening your shot to include other detail can provide some context, but may take away from the detail you've chosen to focus on. When taking a close-up shot, the slightest shake of your hand can blur your photo. Using a tripod or other surface to support your camera as you take your photo will help prevent this from happening. If you want to take a macro photograph of your own eye, a camera with flip screen is the best option because it will allow you to easily see whether your shot is on target and in focus. If your camera doesn't have a flip screen, however, placing a small mirror behind your camera will also give you a view of the display screen. If you're taking a photo of your own eye with a cellphone, you'll also want to use a mirror. This is because taking a photo of your eye on the selfie setting of your phone will affect the lighting of your shot.

article: The study coins and other money is known as numismatics. If you have lots of coins that you want to appraise, or if you frequently work with coins, consider joining a professional group devoted to this area. These groups will share price lists and other special information that can help you determine the value of your coins. Look for a recognized professional group in your area, like the American Numismatics Association or the Professional Numismatics Guild. Websites like Coin Today and Coin World may also allow you to register for membership to access special information. Professional coin appraisers can give you the most accurate, up-to-date value of your coin. They will base their appraisal on their expert opinion of the coin's condition. They'll also take into account what similar coins have been selling for lately. Membership in a numismatics group should also give you access a directory of dealers so you can find one in your area. Coin groups may hold regular conventions when sellers can display coins for interested buyers. Dealers may also be interested in buying coins from attendees. Whether or not you're interested in actually selling your coin, you can use this as an opportunity to determine its "buy" value. Talk to some dealers. Show them the coin(s) you have and ask them if they're interested in buying.

Let the baby play with toys with a variety of textures. You can also encourage play with a variety of baby-safe objects around the house. Your baby is absorbing information through touch as they play with these items. With this in mind, try to get your baby a little time outdoors every day. Exposing your baby to different sights, sounds, and experiences keeps their brains engaged. Do tummy time a few minutes a day to develop strong neck and back muscles and keep your baby interested in their surroundings. Babies need to practice their gross (large movement) and fine (small movement) motor skills. Things like blocks and stacking toys help babies work on grasping early on. As your baby gets a little older, balls and straddling toys will help get them moving. As your baby starts moving and crawling, give them a safe place to explore. Exploring helps them learn about their environment, and it creates the building blocks for spatial intelligence, helpful in things like navigation, mathematics, and sports. Make sure you remove anything the baby could put in their mouth (and choke on) and cover all electrical outlets. Also, remove any kind of chemicals (including household cleaners and even cosmetics) your baby could get into. You can use baby gates to keep them out of areas where they could get into trouble. Babies love playing around in messy textures, and letting them have some free rein gives them a chance to explore the physics of these objects. Finger paints, mud, sand, and water all make great textures for babies to play in, though of course, you should supervise them closely (or join in the fun yourself!). Bath time is a great time to learn about things like how cups are filled up and how gravity works. That is, you don't have to actively teach these things to your child; just give them toys to play with in the bathtub. With a set of cups, most kids will start pouring water back and forth, for instance, which helps your baby learn about things like volume and gravity. Use your grocery store time to engage your baby. As you pick up different fruits, for instance, say their names and let your baby touch them before you place them in your basket. You can also do things like count items as you place them in your cart or say what you're going to do with each thing. Repetition, such as talking about the same fruits every time you go to the grocery store, helps your baby build neurons and create lasting memories.
