Hand Tint allows you to apply postcard effects to photo on Mac. It can modify a picture by making more ancient, black and white, vintage style effects. To use it, select a photo a portrait, landscape, cityscape or still life. Then use paintbrush to tint larger areas like skies, grass, river and so forth with the prominent colors imported from your photo. After that, use “Color Selection” to isolate specific areas and finish with “Restore” by deleting any mistakes. It is possible to save your work.
