Tilt Shift on Instagram offers radial and linear focal adjustment. I’ve just had a play with it and our Fancy Focus does seem very close to their radial option. If you see a difference please let me know exactly what it is.
For their linear focus, you can achieve the same thing by going into our Advanced Tab > Pro Editor > Pixlr Pro and then selecting Tilt Shift from the Filter menu. Then save back to Ribbet by clicking File > Save. Again if this doesn’t seem right please do let me know, but I hope that’s helpful for you.
