Hi all, first post here. I would appreciate your help.

What are the steps needed in Photoshop to create these two effects on any normal picture.

I am not 100% sure but I would try loading an image into photoshop and trialing some of the different filter options - such as poster edges and play around with the sliders to increase and decrease detail.
