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 disabled by default; however, you may enable it for each photo you upload. Image enhancement is recommended for everyone except professional photographers who have already fine-tuned their images. We run the image through very intelligent automated image enhancement software to make the edits. 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, colour and sharpness, the changes made will be very subtle and in some cases may not change at all.
