While lacking more advanced options, InstantPhotoSketch for Mac successfully converts digital photos into pretty pencil sketches. This application is free and performs only one function, but does so without any hassle.
After installation InstantPhotoSketch for Mac opens to a plain but functional user interface. The main menu offers only some basic functions such as open, save as, create sketch, and zoom in and out. There is also a link to the developer's home page. Once the user opens a desired image, they are able to adjust the black level and white level intensity by moving the horizontal scroll bars. The edited file can then be saved in either JPEG or PNG format. The final result seems quite nice and this application indeed successfully converts any digital photo into a real pencil drawing, unlike other similar photo editors where the final result still looks like a washed-out black & white photo. The program offers no other options or features, but there is a pro version that appears to have more options.
InstantPhotoSketch for Mac performs well and will be useful to Mac users looking for a good free sketching program. Users looking for a more advanced photo editor, offering a variety of photo-to-sketch effects, should try out the pro version of this software.
