If you read this post about how to make a watermark you may be wondering how to add your watermark to your photo. If your using photoshop elements this is one way to add your watermark.
Open the image you want to watermark, and open your watermark PNG file
You will see both images open in your bin
With your watermark selected in the photo bin, press ctrl A and then ctrl C, this selects the watermark and copies it (if using a later version of PSE you will be able to drag the watermark onto the photo you want it on.
Select the picture you want the watermark on and press ctrl V (if using mac press command and then the letter)
Once the watermark is on your picture you can resize it, resizing is easy, press ctrl T – this will keep the watermarks proportions. You can now click the corner of the box surrounding the watermark and resize, if you click inside the box you will be able to move where the watermark sits.
Sometimes your watermark may not show up very well, depending on the brightness and colours in the photo, if you want to change the colour the watermark after you have positioned it, it is fairly easy to do.
Make sure the watermark layer is selected (see arrow in the picture below this picture) then click enhance, and replace colour.
Your selection color should be the same colour as your watermark, if its not use the eyedropper tool to suck the colour from the watermark on your image.
To change the colour click result and you will have a new window open, choose any colour and press ok in both windows. I chose to keep my watermark black for this image.
Flatten your image and choose SAVE AS and save your file, it is now watermarked. Make sure you dont name it the same as the original edited file or you will loose the original edited version and be stuck with only a watermarked image!
The end result:
