How To Reduce Noise In Photos With GIMP
Even the best digital cameras cannot prevent pixel noise from occurring in photographs taken using a higher ISO. Luckily, GIMP can help to reduce the amount of noise present in your images. Below you will find instructions on how to de-noise images both manually and automatically with GIMP.
- Select a small Paint Brush from the toolbox.
- Retouch bad pixels by holding down the Ctrl button while clicking on the spot near the pixel you are trying to retouch.
- Now paint over the bad pixel with a color that will blend well.
Note: The Magic Pencil tool works well to retouch small pixel errors and the Smudge tool will also work to blur hot pixels manually.
- Start by duplicating the original layer of the image. This is the layer you will use to retouch the image.
- Now change the layer mode to Value mode.
- Select Filters > Enhance > Despeckle to remove the noisy pixels automatically.
- Now click Filters > Enhance > Sharpen to adjust the sharpness of your image. (Since using the Despeckle filter blurs your image.)
