Can high ISO damage camera?

The camera manufacturer has determined a range for the ISO values. So, you cannot go above the highest possible ISO settings in the camera. Thus, your camera will be completely safe at the highest possible ISO settings. It will not cause any kind of damage to the camera.
What happens if ISO is too high?
If your ISO is too high, the image will be overexposed. The key here is to balance the ISO with the aperture. Use the base ISO value and use the shutter speed that provides the best exposure. This is more ideal when shooting with natural light, in well lit places or where there is plenty of sunshine.Is 3200 ISO too high?
Yes. But the noise produced by modern cameras at high ISOs just isn't that bad; as I mentioned above, you can comfortably boost your ISO to ISO 3200 and ISO 6400 without much loss of quality. And by raising the ISO, you'll end up with much brighter images, even indoors and even at night.What is the downside of shooting at a high ISO setting?
PROS: One main advantage of using a higher ISO is being able to shoot at night in light too dark to see, using faster shutter speeds, and get sharp captures. CONS: Perhaps the main disadvantage of high ISO capture is sensor noise. We'll get into noise reduction solutions shortly.Does high ISO affect image quality?
Why is ISO important? ISO is one of the three components of exposure in photography. It affects how bright your image quality is, as well as the amount of digital noise, or grain, the image quality will have in it.High ISO does NOT cause NOISE! (but f/Stop & Shutter do!)
Is 800 ISO too high?
ISO 800 is half as sensitive to light as ISO 1600. A low ISO value (e.g. 100 or 200) means low sensitivity to light. This is exactly what's needed in bright conditions in order to avoid overly-exposed photos. A high ISO value (e.g. 800, 1600 or higher) means a high sensitivity to light.Does high ISO make pictures grainy?
Since ISO plays a vital role within the exposure triangle (how aperture, shutter speed, and ISO interact with each other to make each exposure), your “proper” ISO setting will change based upon many factors. However, one thing is certain, the higher the ISO number, the more grainy your photos will become.Is ISO 400 too high?
Choosing a low ISO setting, say less than 400, is best when there's a lot of light or when you have a tripod and the style of photograph you want to make allows you to use a long exposure.Does high ISO affect sharpness?
Digital Noise and ISODigital noise from a high ISO can affect the sharpness of an image. Applying the best techniques to avoid digital noise is crucial when you're looking for the highest quality in your photos, especially in night photography.
