The task is to show how to create a Facebook Frame and a Snapchat GeoFilter, themed for Casa Loma. I used a Samsung S6 to take a number of photos for a previous exercise.
First, you must select an image to use in the Frame or Filter. It needs to be transparent, so use Pixlr.com to modify the image.

Edit your photo and save as a .PNG file.
Facebook Filter
Open Facebook Frame Studio and select Create Frame.

Bring your image(s) into the frame using the Upload Art button. Drag and Drop your .png files and arrange in a suitable pattern. Be sure to leave room for the selfie.

You can see how your image places on mobile and desktop screens, to the right of the main drag and drop work area. Once you are happy with the images and placements, click Next.

Name your Frame, add #hashtags and complete location and scheduling info.

If you like what you see, hit publish to create your Facebook Frame. You’ll get a notification on your mobile account shortly!

Snapchat GeoFilter
Login to your desktop Snapchat account. Click on OnDemand GeoFilters, underlined by me in red.

Select Create Filter

Design your GeoFilter.

Select any combination of your uploaded file(s), Snapchat themed frames, add text, pencil tool additions and/or elements like Bitmoji.
Preview your filter and once you’ve approved your design, click next to set date, location and payment information. Here’s mine!

It’s that easy!
