article: If you're taking Tumblr pictures with a webcam or a camera embedded in your computer, positioning is key. You don't have the freedom to move and shoot pictures as you please with these sorts of cameras, so you'll want all of your interesting furniture and decorations positioned behind your computer desk. Cameras in laptops offer a little more freedom, but you'll still need to stick the angles that are possible to shoot through the embedded camera's lens.   Working with these sorts of constrained cameras can make it tricky to get your whole room in the shot. This can actually work to your advantage if you're willing to put in a little extra work. Cycling interesting furniture and decorations into the frame can allow you to make interesting combinations. If your room has windows that face the sun, try opening them during the day to give your room some natural light. Bright daytime shots can turn a dark, dingy bedroom into a clean, open-looking space. However, sunlight can also illuminate unflattering details that aren't visible when your room is dark, so make sure your room is clean and tidy before snapping your shot.  Be careful when shooting directly into the light from the window; if the sun is bright, this can make it difficult for your camera to pick up detail in the rest of the frame. A sideways or diagonal may be a better choice in this case. Try to position close-up shots so that the focal object is against a shaded backdrop rather than a bright light. Make full use of your lamps and decorative lights at night. Try to light your room just brightly enough that your camera picks up a reasonable amount of detail. You won't want your room so well-let that you lose the smoky, shadowy quality of a dimly lit room, but you also don't want your room so dark that the contrast between shadow and light isn't clear. This may require a little experimenting to get just right. Don't use a flash when shooting your room at night. Often, this can create intense, uneven lighting patterns and harsh glare on shiny objects. Unfortunately, without a flash, the camera's shutter has to stay open for longer to get an image, which can lead to blurry pictures. If you can't get clear shots without a flash, try lighting the room more brightly or using a tripod so that your camera is held perfectly still. Bedrooms can sometimes be cramped, claustrophobic spaces. If this describes your room, try using volume-increasing visual tricks to make your room look as big as possible. With the right color choices and positioning, you can make your tiny room much, much bigger. Below are just a few types of things you may want to try.  Use light colors whites, pastels, and other neutral colors create the impression of wide, open spaces. Avoid leaving lots of items on shelves and tables. This can create a cluttered look. Add mirrors, which reflect both light and color to make the room look much bigger. Space your furniture out to create open floor spaces. For the best photos, you won't want to use a webcam, a computer-embedded camera, or a phone camera. Instead, you'll want to use a high-quality digital camera. It's hard to beat the clarity and detail of a great camera, but keep in mind that this added level of detail will capture everything, even crumbs, stains, and other ugly blemishes, so you'll need to keep your room clean accordingly.   With digital cameras, you’ll usually want to keep your ISO setting below 800 when shooting indoors. It's usually possible to adjust this setting manually; consult your camera's instruction for more information.
