Mimic noise in Photoshop’s Adobe Camera Raw Filter
16Adding noise to your images is easier than ever in Photoshop, Adobe Camera Raw and Lightroom thanks to the Grain controls available in the Effects tab. In Photoshop you can use the Camera Raw Filter to open up the full set of ACR controls including Grain. If you do this, copy the Background Layer and Convert for Smart Filters, which means that you can save the image as a TIFF and then access the ACR filter later if you need to make any further adjustments. To add grain there are three sliders: Amount, Size and Roughness, and they’re all pretty much selfexplanatory and quite effective.
