Liquify

Liquifying is primarily used by fashion photographers, to enhance features on models, they are able to increase certain aspects, or decrease certain aspects, this can be done to make someone look more visually appealing.

To start using the liquify tool go to filter then liquify.

looking at the picture alex is not a model, although it is primarily used on models,  have shown examples of the liquify tool being used, i used the bloat tool to make his pupils bigger, and i used the shrink tool to make his nose slightly smaller. Subtle changes like this can make all the difference in a photograph.
