Having your work ripped isn't so nice...so here I'll explain you a few steps to create your own watermark.
Open a new document 300 x 130 px with transparent background (you can use any size you prefer, this is the size of the final single watermark).
Choose the Text Tool and type the text you want to become your watermark.
Now press CTRL+T and rotate it a bit.
Now choose Edit>Define pattern and name it "watermark".
When you want to watermark some of you work you simply have to open your file (digital shot, photoshop work etc...), create a new layer and choose Edit>Fill, choose the pattern you just created
and lower the opacity of this layer to match the desired result.
