1. After opening a photo, in the menu go to Filter->Stylize->Solarize. This will perform solarization filter.
Solarisation is a phenomenon in photography in which the image recorded on a negative or on a photographic print is wholly or partially reversed in tone. Dark areas appear light or light areas appear dark.
2. Now we shell invert our image. You can use either Ctrl+I either in the menu go to Image->Adjustments->Invert.
3. Now, our poster is too bright. Let us perform Auto Color. In the menu go to Image->Adjustments->Auto Color. Also you can use Auto Color Button from the toolbar.
4. Now in the menu go to Image->Adjustments->Posterize. This will launch the Posterization dialog box. By default we are suggested 10 layers. For this high-contrast and colored image, a good layers range is [8; 24]. You can play with the slider to chose the best result. I chose 20 layers.
That's it! hAVe fun
