Fighting artifacts

Hello, dear visitors of the site Photoshop-Master.
I often have to process photos. The main problem that arises in this case is the fight against squeezing of JPG-files (with strong compression, there are “squares” with dimensions of 8×8 pixels). At one time I found an interesting method of dealing with this phenomenon.

Step 1

Part of the original photo

On the eyebrows and in the hair, those notorious “squares” are clearly visible.

Step 2

Create a new document with dimensions of 8×8 pixels and with a transparent substrate.

Step 3

Maximize the document for easier drawing. And tool Pencil (Pencil) diameter 1 pixel, black color draw square

Step 4

Choose a menu Edit – Define Pattern (Editing – Define a pattern) and in the dialog box confirm the creation of a new pattern.

Step 5

Create a new layer on the edited photo.

Step 6

Choosing a tool Fill (Fill), set the fill pattern and in the drop-down box, select the pattern we created.

Step 7

Fill the newly created layer Layer1, the result should be like this:

Step 8

Choose a menu Select – Load Selection (Selection – Load Selection)

or it may be easier with the key pressed Ctrl left click in Layer Palette on the image layer Layer.

Step 9

Switch to the bottom layer (with photo) and key combination Ctrl + J create a new layer of our selection – Layer2. Layer Layer1 can be removed – we no longer need it.

Step 10

Being on a layer Layer2 call the menu Filter – Blur – Gaussian Blur (Filter – Blur – Gaussian Blur) and blur with radius smooth 1 pixel. Layers can be merged into one (Ctrl + E).

The obtained result allows you to fully work on with the original photo.
