Relocation of Objects
So now you can remove people from picture, so what next? Well, how about learning how to move something from one picture, and making it look natural in another? Hope so because that is the lesson.
For the most part you can use this to add yourself, or others into pictures. If you are really bored you could even start to add things to pictures that may not belong there. Unlike a previous post where you learned to insert a person who was in the same type of scene... How about adding something completely crazy and making it look as if it could have been there.
For this tutorial, I will be using a request I was recently given. Photoshopping a monkey into a teacher’s classroom. Below are the two original pictures.
The first step after getting the two pictures into photoshop is to go the the image of the monkey and use either the pen tool or the lasso tool and select closely around the object.
After the monkey has been closely selected, you are going to want to refine the edges to erase the majority of the excess background that was also selected. To do this, right click inside of the selection and choose refine edge.
Once you have refined the edge, hit ctrl c to copy the object (cmnd c on a mac) and then hit ctrl v to paste the object into a new layer (cmnd v on a mac). In some cases there will still be a few areas along the edges that will require cleaning up, but in this case using the refine edge will erase the background well enough that no additional erasing will be required. Just keep in mind that every image selected will refine differently than others. The best way to tell if the edges have been refined enough is to hide layer 1, which is the layer that holds the original picture. To tell if the layer has been hidden, look next to the layer name for either a eye icon or a blank box. If the eye is visible, so is the layer, but if you only see a square, the layer is not visible.
As seen above, Layer 1 is hidden and the Background is visible. When you hide background it will show you what was left after the edges were refined.
After you clean the object that you are going to be relocating, you next step is to copy and place the object into the other picture. To place him in the other picture, select him and hit ctrl c (cmnd c on a mac) to copy and then go to the picture of the background and hit ctrl v (cmnd v on a mac). In this case, the monkey will need to be flipped to be placed correctly. To do that, go to the edit menu and choose Transform and then select Flip horizontal.
Now the monkey is facing in the right direction. The next step is going to be to lower the opacity to be able to line the monkey up correctly, in this case, to fit in the chair.
Now, you may have noticed that the monkey looks as if it was simply just placed over the chair. To fix this, we will need to enable a layer mask. To do this, go to the bottom of the panel on the right hand side of the screen under the layers and select the icon that shows a circle inside of a rectangle. When you leave your mouse setting over it, a description will pop up and read Add layer mask.
The layer mask is shown inside the red rectangle below.
If the layer mask is black, just select the paintbrush and choose white as your main color.
Then right click on the picture and it should open a window with settings for the paintbrush.
The settings you will want to use is the size brush that you believe that you will need to be able to work (just remember that the brush will fade the edges more, the larger the size is), and set the hardness to 0%. Once the paintbrush is set up, begin to paint the area that you remember your object being placed. At first you want to uncover the entire thing before you begin to hide the parts that you do not want. Once you have uncovered the object completely, switch your paint color to black and then, if need be, reduce the brush size and begin to paint over the areas that need to be erased.
If you look at the picture above, you will notice that the middle of the face is missing. You do not need to worry that you just erased the image. With a layer mask enabled, if something looks to be erased, the object is just hidden. To fix the issue, all you need to do is switch your paint color to white and paint over what disappeared and it will reappear. Once you have finished painting, you are essentially done.
Now it looks as if the monkey is sitting in the chair. The only issue is that, if you look closely, the quality of the monkey is different than the background and stands out. To fix this you first need to identify the major differences between the two images. With this image the fix is using motion blur. This effect will apply a blur to the monkey, while leaving the background the same. The blur will make it look as if the monkey belongs in the picture more. To use motion blur, go to the filter menu and go down to blur, the select motion blur from the side menu. When you choose motion blur a window will pop up and you will see the image that is selected blur.
As you can see, the blur value is too high to match with the background. To fix this, all you need to do is lower the Distance value until the amount of blur on the object matches with the background. The image below looks a lot better than the image above, because the blur is pretty much even between the background and the object that was placed.
Once the blur is to the level you want, hit ok. The last step is to adjust the two images so they match up more. To do this go the the image menu on the top of the window and select adjustments and then choose brightness/contrast and hue/saturation. Leaving you with the picture below.
