There are a few things you need to know if you want to edit a scan in Photoshop. First, make sure that the scan is in the correct resolution. Second, make sure that the image is properly cropped and resized. Finally, make sure that all of the layers are set to “normal” mode and that the “image” layer is selected. Once these steps have been completed, you can begin editing the image by selecting any of the tools available on the palette and using them to change or remove details or color.
