To visualize the different effects possible with Photoshop we will create a mosaic. Make a new A4 landscape base background on Photoshop with a 72 dpi. Take a picture from the Internet that must be a square.

Fit five copies of the picture in vertical applying each time a new layer with a new effect. Choose each time an effect from a different category so that the surrounding pictures do not have an effect from the same category. You can use effects in the same category but you must use each effect at least once.

Once completed, upload the PSD file to Moodle and make a new post with a PNG copy. Name and describe starting from the top right of your picture each effect you used.
