Effects only change the photo. Titles and stickers in the collage stay crisp, which is why posters with fluted or frosted glass work so well.
The defaults are deliberately subtle. Pull the strength slider up for a poster look, or down for something finer.
One effect across all photos makes a collage feel consistent. Different effects per photo work for series or comparisons.
Short answers.
It makes a photo look as if it sits behind ribbed glass, like shower screens or cabinet doors, also known as reeded glass. In mosa it comes vertical, horizontal and round.
Under “Filter”, choose the “Effects” tab, then Glass and Frosted Glass. The strength sets how blurred and bright the photo gets. With Clear Window, one area stays sharp.
Use the “Coming Soon” template: fluted glass, a big title and a small line are already in place. Add your photo, adjust the text, save.
