In recent years, most camera manufacturers have made huge efforts to decrease digital noise. Today’s DSLRs can take photographs at previously unheard of ISO sensitivities, while still keeping the noise levels reasonable. However, digital noise is sometimes unavoidable.
Luckily, Adobe Photoshop includes some tools to help you reduce the noise in your images. ExposureGuide have posted an easy-to-follow guide on using these tools. One important thing to remember is not to overdo the noise reduction, as it will reduce the details in your photographs.
