Steps to make a dotted mosaic in Photoshop:

1. Open image
Select File> Open to open your photo. Duplicate the layer to backup your original photo by choosing Layer> Duplicate Layer or Ctrl + J. You can hide the original photo visibility options. 

For this Photoshop tutorial, I'll use this image, girl-676185, that I downloaded from Pixabay.

2. Create a new layer for background
Choose Layer> New Layer or shortcut Ctrl + Shift + N. Fill it with the background color of your choice by choosing Edit> Fill. Click the drop-down menu, I would choose Black color and then click OK button.

3. Apply Mosaic filter
Select Filter> Pixelate> Mosaic. Please fill in the Cell Size depends on your photo. I will give the value of Cell Size 40 px.

4. Create a document for the dot pattern
Create a new document by choosing File> New or Ctrl + N. You must fill in the Height and Width column with the same size with the mosaic filter size that you just created earlier. For this example, I will create a document with size 40 height and width of 40 pixels. Fill this document with a background color. I'm going to fill it with the black color by choosing Edit> Fill, choose Use column Black and then click the OK button. 

Create a circular selection using the Elliptical Marquee Tool. 

Press Delete keyboard button. In order to form a perfect circle, make a selection using the mouse while holding down the Shift key. 

Lastly, create a pattern by choosing Edit> Define Pattern. Please fill in the name of Pattern Mosaic pattern eg 40x40, then click the OK button.

5. Create a mask
Back to document mosaic photo, then create a mask on the photo by choosing Layer> Layer Mask> Reveal All.

6. Fill mask with the dot mosaic pattern
Make sure the mask active by click on it and then select Edit> Fill, choose "Use" drop-down and then select the pattern mosaic pattern that we created earlier. Click the OK button. Now, the circle mosaic photo effect has been completed.
