Posterjack offers a free image enhancing service to all of our customers. This option is displayed in the Photo Art Editor after you upload your photo. The service is automatically enabled; however, you may disable it for each photo you upload. Image enhancement is recommended for everyone except professional photographers who have already fine-tuned their images. Our image enhancement process will make significant changes to images that need a lot of help to look their best. The results are incredible! If your image is already very good in terms of exposure, color, and sharpness, the changes made will be very subtle and, in some cases, may not change at all.
