I've bought a domain and hosting to create a site on photo editing service. But I don't know which one is the best Premium WordPress theme for photo editing services. If any one suggests I will be grateful to him.
Try the X Co theme on Themeforest. You can achieve almost any look and layout you wish with their easy visual builder.
And how about a plugin with "before and after" versions of the photo? Something like https://wordpress.org/plugins/before-after-image-slider/ ? The theme depends on how you would like your website to look like. Could you show any examples of websites that you like?
