In one sentence, describe what the following article is about: The focal length is represented by two numbers with a dash in between (i.e., 18-55). It marks the distance from the camera lens to the sensor. A wider range makes a camera better at taking  photos from a distance. A shorter range means a camera will be better at shooting single scenes up close. For example, if you take a lot of photos of family events, you're taking mostly close-up shots of one scene. If choosing between a focal length of 18-55 and 18-35, go for the 18-35 lens. Image stabilization prevents blur by keeping the camera steady when taking photos. Pentax and Olympic cameras have photo stabilization built in with a camera's body, so you won't need a lens with this feature. If you have another brand of camera, however, look for a lens with image stabilization. Image stabilization is labeled differently between types of cameras.  Canon simply uses Image Stabilization, or IS. Fujifilm, Panasonic, and Samsung us the term Optical Image Stabilization (OIS). Nikon uses Vibration Reduction (VR). Sony uses Optical Steady Shot (OSS). Sigma uses Optical Stabilization (OS). Tamron uses Vibration Control (VC). Aperture refers to the amount of light a camera lens allows in and is represented by f-stop ratings (i.e., F4). Smaller numbers indicate a camera lets in more light. A smaller aperture works great for more creative photography, as they allow you to focus in on a close up of one specific object. However, a larger aperture works best if you're just photographing to capture events in your daily life. A larger aperture allows you to take photos indoors without flash and shoot without a lot of light. For example, if you use your camera to photograph family get togethers, an f-stop rating of F4 should be fine. However, if you use your camera to take creative photos for a photography class, go for a lower f-stop rating, such as F2. A prime lens is generally a solid choice, as it can be customized for a variety of photo types and is generally the most versatile. However, if you're taking very specific types of photos, pick a lens type that will provide the right zoom for your needs.  Wide-angled lenses allow you to better photograph interiors of buildings and other structures. Macro lenses work great for extreme closeups, such as nature shots of leaves and flowers. Telephoto lenses can be helpful for long distance shots.
Summary: Pick a focal length designed for the type of pictures you take. Check if you need image stabilization. Use the f-stop rating to select your aperture. Check how the lens type affects zoom capabilities.

Gently conclude your email by giving a quick closing remark before signing off. It should be friendly and does not have to contain a lot of detail. A sentence like, “Anyway, I need to to hit the books!” is a perfectly good closing remark. Add a quick statement letting your recipient know that you want to hear back from them. Writing, “Let me know if you need anything else,” or “I can’t wait to hear what you’ve been up to,” is friendly and casual. Ending an informal email can be much more casual than a formal email. Depending on your recipient,  sign-offs can include:  Love Cheers See you Yours Bye With an informal email, you typically don't need to sign your whole name. The recipient already knows who you are. It is perfectly acceptable to just sign your first name.  If you are writing someone close to you, you can also use a nickname. If friends or family members call you by a nickname, it can be fun and friendly to use that when you sign off.

Q: Place your nails under a UV light for 1 minute to cure the primer.

Let the nails dry for 25 to 30 minutes before applying another coat. If you like, you can finish with a top coat to protect the gel nails.
A: Cure your fingernails for 1 minute under a UV light. Dry the nails completely under UV light for 3 minutes between coats.

Article: After you finish a draft, read it with a pencil in your hand, or your finger on the delete button. If you see something that repeats a point you've already made, or wastes the reader's time, delete it. Anything that isn't working to prove the main idea is ineffective wasted space. It's sometimes necessary to eliminate unnecessary sentences, ideas, points, sections, or even paragraphs to make a piece more effective. Make sure your subjects and verbs agree, and replace weak verbs to avoid passive voice. Weak verbs include "is" "was" "be" and "have." Learn to replace weak verbs with more active verbs to make your writing more vigorous.  Instead of writing "A big crowd has been lured downtown," use a stronger verb than "has been." Try, "The festival lured a big crowd downtown," replacing the verb with the stronger "lured." Look for sentences that start with the word "there" for a quick tip to weak verbs. Bad writing is wordy and wastes the reader's time. Good writing is concise, cutting straight to the point. Don't use two words when a single more accurate word is sufficient. Instead of writing "The party was super fun and exciting," write, "The party was thrilling." Any sentence that involves multiple "ands" or semi-colons needs to be cut into more than one sentence. In general, avoid semi-colons and sentences with more than one clause. Does your writing accomplish what you wanted it to accomplish? Does it explain the main idea fully and clearly? If so, you're ready to move on to late concerns. Read over the improved draft and look for misspellings, typos, and punctuation errors. This should be one of the last things you do with a draft before it is finished. Ask a friend or family member to read your writing and ask them for specific feedback by having them tell you what they thought the main idea was, or having them write it at the end of the piece. Did they get it right? If not, keep working to make it more effective.
Question: What is a summary of what this article is about?
Cut everything that doesn't move your ideas forward. Replace weak verbs with strong verbs. Eliminate unnecessary words. Look for run-on sentences. Look back at your original purpose and make sure it matches. Proofread last. Get feedback, if possible.
