Okay, so I've been trying to create a grid, but so far I can't seem to get it right. Basically, I want a grid, that covers each pixel in an image. Like, each pixel has a black outline, sort of. So far, I've come up with this, by creating a pattern. But, as you can see, the individual pixels aren't outlined, but a big box essentially covers tons of pixels.
However, what I actually want, is this effect, as you can see below. I can't seem to get it right.
Right now, I'm using the Channels layer section in PhotoShop to do this, as that's something I found that worked in a tutorial.
Here is another example of what I need
Any help would be highly appreciated, thank you!
