The Liquify filter on Photoshop creates a pretty cool effect on photos that you may want to have a sort of fantasy look. You can also use it to create a dissolving effect by creating multiple layer masks, but for now I’ll just cover how to liquify your photo.
Open the photo that contains what you want to liquify. For me, it’s this door.
Use the quick selection tool to select what part of the photo you want to add the effect to. Just drag the tool until the subject is surrounded by the dotted line
Right click on your selection and choose “Layer via Copy”. It will create a new layer that only has your selection in it.
Click the little eye icon next to your background layer to make it invisible. Use the fill tool to fill in the background space with white, or whatever color you wish.
Go to the Filter tab at the top and choose the second “Liquify…” option. This will open your selection in a new window.
Use the Forward Warp Tool to drag the edges of your selection to make them longer and warped. You can change the size and strength of the tool on the side menu. When you’re done, click okay, and you should have your finished liquified selection left in it’s layer.
