It's one of the many possible variants of a half-tone or grid pattern. There are many ways to do this. Here's a couple.

1. With the half-tone filters in PS, the size of each dot depends on the brightness of that area, so one would have to generate the desired dot size and spacing using a uniform mid-gray level as input and then put the resulting uniform dots on their own layer with an appropriate blending mode.

2. You can also do the same sort of thing using the commercial "halftone" filter plugin by VanDerLee (http://www.vanderlee.com/plugins_halftone.html).

3. You could run Rosenman's free "scan lines" plugin twice, once in the horizontal direction, once in the vertical direction, or use his "grid generator" or his "pixelate" plugin, or etc. etc. (http://www.richardrosenman.com/software/downloads/ )

4. And, if you are an inveterate do-it-yourselfer, there are plenty of ways you do this using only the native tools built into PS.

HTH,

BTW, be prepared to have to endlessly tweak the spacing and size of the dots depending on the output resolution of your image, whether or not you anticipate it being resized, etc.

Nice effect. I just used Example 1 above as posted by Tom Mann. Got excellent results. I shall be noting this one down. (I have to or I'll forget )

When the filter is applied to a solid pale gray layer, the dots are created in the current Foreground Colors. So if you want black, make sure this is set to black beforehand. However, other colors are worth experimenting with for the effect.

As Tom said, using native tools, I would try a pattern fill layer using this type of pattern (I made this really fast so its bad!)



Adjust your pattern scale and the layer opacity, and you get pretty close.
As I said, my pattern is off.

I tried option 1 but I get a different effect, I am looking fir that very little square filter, are there any filter plug in collection on sale for this sort of thing? I find it hard to achieve using the PS toold with my basic level of fs knowledge, vanderlee seems to work for windows only

How is this? This is using option 1. You can lighten the overlay, but I left it darker so you can see the pattern better in the example.

Looks great SPWA, but if you examine the the pattern used in the photos in the OP's link, you can see the pattern is made of cut out dots/circles which allow more of the BG to be seen. The Halftone filters use solid dots/circles which are not quite the same.

I mention this because I forgot to in my previous post.

edit: I just pulled one of the images off the site and there is no pattern on the originals, whatever is creating the pattern is in the viewer.

Yes, that´s a wordpress theme, and that overlay is an option you can use in the photos, and looks great in my opinion, I have seen it in several wordpress themes. That´s whay I thought it should exists a filter like that somewhere, I don´t know if they do it, any other ideas? this should be a simple thing for a filter
