As long as you shoot snapshots in the sunshine, you will remember nothing of it. But when you are shooting under overcast skies, or indoors, you may get grainy images, which also lacks the detail drawing. With these tricks you can avoid the "intoxication" for your camera:
- Note the ISO speed. The higher the ISO number, the more comes out noise. In small compact cameras arise from only ISO 400 quite noisy recordings, digital cameras usually feature a photo at ISO 800 still on virtually noise-free.
- If permitted by the subject, rather heraufzuschrauben choose a longer exposure time than the ISO number. Use a tripod to counteract camera shake.
- Even the flash of your camera can help to minimize image noise. Keep in mind that even the mini flash many compact cameras is pretty weak. In stores, there are about 40 € from external flash units, which are much more powerful.
- caution even for cameras with "ISO anti-shake". These cameras counteract camera shake by increasing the ISO speed automatically to prevent falls below a certain exposure time. Instead of camera shake is there, but noisy. Turn if necessary, the ISO anti-shake, and use it instead of a tripod.
- If it is not but make the highest quality level one on your camera (such as "Extra-Fine). To avoid at least that disfigure next to the sensor noise and compression artifacts still your shot. Even better: Take your photo in the RAW format. This gives you the best conditions to disturbing noise later with Photoshop Elements get rid of.
