Photoshop has a lot of little extras that really make life easier in advertising agencies, even for quick blog posts. Often you don’t get a perfect photo in the important situations. Often, perhaps only one employee has photographed with the mobile phone. Subsequently, the image quality is of course accordingly. For whatever reason, with the soft focus you can save many too small, slightly pixelated photos for your own homepage. The effect is also used for perspective and blur. If the entire image is somewhat pixelated, things in the background are softened, making the image appear more focused and sharper.
