Long before the retro photo boom and the rise of apps like Instagram and co. Büro Destruct created the «Vintage Foto Droplets» for Photoshop back in 2010.
Simply drag your photo(s) or folders containing photos (they must be JPG's in RGB mode!) on either the "red", the "green" or the "cool" droplet icon and let Photoshop do the rest. The resulting photo(s) will contain following editable layers for further editing: original foto, vintage color, vignetting, white border and black border.
Changes in the 2022 version (Mac only): The droplets are optimised for the use of larger sized fotos (8 – 12 MP) from your smartphone. Because of security restrictions of macOS, there is a little workaround needed to make the droplets working. Please read the Read Me.
