Most of the things mentioned above can easily be done with good software. It is often less time-consuming and cost-effective as well to outsource these to an experience photo retoucher. Also, some retouching issues are not easy to handle if you do not have enough experience.
Experienced retouchers know the perfect balance that one has to apply when using many features of a photo-retouching software. For example, too much use of dodge and burn can give your image a fake and ugly look.
Moreover, PicsRetouch with many experienced retouchers have experts dedicated to different aspects of photo retouching. For example, one person might create clipping path and clip the image. Another retoucher can adjust the lighting and brightness and correct the color and hue temperature. Yet another will be assigned to remove unwanted elements from within the product and add or remove shadows.
You can see a well-established pipeline system can offer a turn around that is too quick and much cost-effective. Also, it gives you enough time to focus more on your core business and leave unproductive work in the hands of experienced, dedicated people.
Also, the product image might not look great because of bad lighting, too much or too less exposure, something shining here and there, light or dark spots, and all sorts of unnecessary elements. You will also have to struggle with issues like cropping, resizing, transparency and background.
