This is a bit complicated to say. If you don’t have a basic understanding of PS, it will be difficult to do it well.

1. Select a picture. It is best to start with 2 pictures whose color, pixels, etc. are not too relevant;

Second, cut out the pictures. Cut out a picture of Kobe Bryant (or yourself). Cutting out is also one of the difficulties. There are methods such as color cutout, rope cutout, pen cutout, magic wand cutout, filter cutout, etc. For example, when cutting out hair, it is best to use the channel cutout method;

Third, paste the cut out picture and adjust the position, size, color, angle, etc. to a moderate level;

Four, make shadows. Add some shadows so it doesn't look fake, dangling, etc.

Fifth, merge the layers and it is basically completed.
