In any case, we hope that the photo you are editing is good enough and that not too much work needs to be done. However on the path to perfection, this is usually not the case. To meet the brand guidelines or the requirements for a marketing campaign, you will likely need to crop your image to the correct size and orientation. Clean up the image using the Clone tool, disposing of any unwanted marks, and smooth out dirty areas. Altering the color map, upping the contrast, and sharpness are other ways to reach a satisfactory result.
