      Important to remember to avoid grainy photos.
  • High ISO – As we briefly talked, higher the ISO, higher is the amount of grain. Low light – Photos become grainy if enough light was not available when the photo was taken. Too slow shutter speed – One school of thought believes if shutter speed is very low and light is low, photos may have lot of grain and noise. Camera – High-end DSLRs usually perform better in low light and handle high ISO with minimum noise. Same can not be said about low end DSLRs and point and shoot cameras. These type of camera have a small sensor, leading to high noise as effective light getting to sensor is lesser than if it were a high-end DSLR, which have a bigger and better responsive sensor. Excessive Post Processing – Another reason for grainy photos is over adjustment in post production. When sharpness of a photo is increased, grains/pixels in a photo become more prominent. If this adjustment is overdone, photo becomes grainy in no time.

    Notes: Exposure - The light meter is different from the exposure setting. - Keeping your light meter at "0" doesn't necessarily mean it's the perfect setting. Just don't stray too far from the "0". Adjust to your liking. - Positive numbers on your exposure setting will make your photos brighter. - Negative numbers make your photos darker. Aperture - Small numbers (like f/1.4) have larger openings, which let in more light. - Big numbers (like f/16) have smaller openings, which let in less light. Shutter Speed - Seeing 100, 250, 320, etc. on your viewfinder means "1/(number seen)", like "1/100". - Try not to use 1/60 or less when handheld, that's when you use a tripod or look for something steady. - Using longer exposure (slow shutter speed) will let in more light. - Using shorter exposure (fast shutter speed) will let in less light. ISO - ISO is the sensitivity of your camera to light - Lower numbers are less sensitive to light, which give smoother photos. - Higher numbers are very sensitive to light, which give very grainy and noisy photos.
