Thanks! Normally I use lightroom for all my photo edits, but for this project I used Photoshop. Its much easier and has more powerful tools to achieve the tilt shift effects I am after.

I found that filter option in Affinity Photo and it worked decently. I think this would look better if my angle was higher.

Yes! That is the key with tilt shift. You need to be at a raised position above your subject so that you are shooting at a down angle.
