The best Photoshop work goes unnoticed (which is the whole point from an advertising perspective at the end of the day!) Used correctly, it enhances a photo and can be used to remove flaws. Clearly its good practice to check and improve any photo you use even if it is just making sure the contrast is ok. Untidy or low quality images look unprofessional and can reflect badly on your brand. But it’s about being subtle, about having the skill to change and adjust the image so that it is improved without revealing the process of improvement.
