To create the partial photo mosaic, we cut out the area you mention and place it over the photo mosaic. Just drop us a comment when uploading you images for the free preview. Thus, you get a mixture of a photo mosaic and your original main image.
It is perfectly suited to keep and display small details of the main image. You can also highlight certain areas of the image to give the photo mosaic a 3D-ish effect. This kind of mosaic is therefore often used for a wedding mosaic picture.
For the free preview your desired area will be cut out roughly. If you like your partial photo mosaic, we will cut out the area perfectly afterwards.
