The key point of this effect is to create a selection, where it should be shown and where it should be hidden. So let's get started here.
The first step is to open the image and copy a layer, called a background copy.
The second step is to build a new layer, called Layer 1, and use the rectangular tool to pull out a suitable rectangular marquee on the image.
In the third step, select layer one and stroke with the appropriate pixel.
The fourth step, add layer style to layer 1, get own satisfactory frame effect. You can edit the layer style and adjust the specific parameters to meet your requirements. Of course, you can also directly use the ready-made style palette. You can also call the style in the Style palette before you adjust the parameters for some of the effects. This is a quick and efficient way to make a picture frame that I stumbled upon oh, uh ...
The fifth step, to make the frame of the Free Transformation (ctrl+t), so that the perspective effect as shown. In the course of operation, we should pay attention to the layer's hierarchical relationship, as well as layer selection problem, because it is very important! Please pay attention to my layer palette. Layers of hierarchical relationships and choices are something that should always be focused on.
Step sixth, and then copy the background to a layer, named background Copy 2, reduce layer 1 opacity (easy to make selections through transparent frame) and enlarge the image, make the head selection as shown. Then select Background Copy 2 to add a mask.
The point of adding a mask is to hide the part of the head selection.
The seventh step is to make a selection at the edge of the frame and save the selection as shown in the picture. You can use a multilateral lasso tool or pen tool to make a selection. (In fact, it doesn't matter whether you're here or not, the selection is mainly used on a background copy, so that the parts outside the selection are hidden.) After making a selection here, you can also select a background copy and add a mask directly.
Step eighth, select a background copy, load the selection you just saved, and add a mask. At this point, the effect of the draw frame has been completed. Note the layer hierarchy, the background copy 2 top, layer 1 under it, background copy below layer 1, other layers hidden, as shown:
The Nineth step, and then build a new white filled layer 2 as the background, so that the effect can be seen clearly, ah ... Here, this new layer, you can draw the wall on their own, you can drag from other materials into a suitable background to hang this strange painting.
From another place to find a piece of material, you can take to practice.
