Here are some useful tips on using your camera (be it a cellphone or otherwise) to take photos or videos for submission to YouScoop:

Get as close as possible

Even if you have a high-resolution camera, it's always best to get close so that you can get a better look at your subject. But be careful! Don't get too close if it would be dangerous for you to do so (such as if you're reporting a large fire or an ongoing crime). Use common sense and judgment.

Keep still

The steadier you keep your camera, the clearer your images will be. If you can, lean against a solid object (such as a windowsill, wall, or tree). Also remember to keep your camera still even after you've taken the photo, because some cameras experience "shutter lag".

Just keep shooting

Especially when you're trying to cover a rapidly unfolding event, don't think too much about composing your images. Just snap away then later choose the best photo or video to upload. Sometimes, it's more important for you to get a quick shot than to waste time thinking of the best angle or lighting, only to miss everything entirely.

Use the highest possible resolution

Most cameras these days (even on cellphones) allow you to choose the picture quality or resolution. The higher the picture quality or resolution, the more details you'll be able to capture. Just keep in mind, though, that higher resolution also means bigger file sizes - so you won't be able to take as many pictures.

Never use digital zoom

Be careful of this, because it decreases the quality of your shot. You may be getting a close up picture of your subject, but it will also be blurred and pixilated. However, if your camera has optical zoom, feel free to use that!
