How did they do this?

1. How did they create the pretty nature background?
2. How did they do the grid thing?
3. How did they do the border? (Yes, I am talking about that very simple black line lol)

Thank you!

The background looks like an altered photograph.

The grid: Simple, Make a new document at 5 pixels x 5 pixels trans background, zoom in on it and make a selection on the top and left edges (like an L shape) 1 pixels wide and fill it with black. Edit > Define pattern
Now you can fill anything with that and it makes a grid. Edit>Fill and select your grid pattern (you can make different sized ones for different sized grids.)

The border make a selection and go Edit > Stroke.... select the size, color, placement and viola a border.

Okay thanks Lion, your really helpful!

When you say "altered photograph" do you mean they took the picture themselves then some how edited it? It's really pretty, and it's not the first time I've seen a nature background like that.
Any idea on how they made a picture look like a drawing?

Most likely they found an image of a sky and did some alterations in Photoshop, Do something like duplicating the layer and on the "top" layer start changing the blend modes untill you see something like that. "color dodge/burn" might get something similar.

Have fun! play with it! sqeeze some pixels and stuff! :D

Alright, thanks so much lion!

Oh, and about the grid, do the intructions you gave me fade? Because that's what I was looking for

You sound like an expert on photoshop lol.. do you have a gallery for your work?

No the steps I gave you won't fade them...

To fade them... first fill the area with your grid....

Then on the layers pallet click the layer mask icon, hit D on your keyboard to make your colors black/white and select the gradient tool. in the gradiant tool options at the top of the photoshop window make sure you have the background/forground gradient selected and drag the gradient tool abou8t halfway across the area you filled with the grid. (you'll see the results.)

A gallery.... Well.. Lets just say I'm working on it. The overwhelming majority of my work I can't post publicly as it appears in print (client restrictions), but I'm trying to get a website together right now.
