This Photoshop tutorial shows you all the steps to make a watermark from a signature. How to make the signature and prepare it in Photoshop so you can add your personal signature to your images. You will also learn how to make it reusable. (Don’t use your legal signature, create an “artistic” signature for this).

If you want to check, here’s another tutorial where I described how to make a watermark out of your logo.

STEP 1

Grab a white sheet of paper and a pencil. I’m using paper with a coarse tooth and a soft 4B pencil to get some nice texture,
Draw your signature on the paper and make sure it’s nice and big.

STEP 2

Take a photograph of your signature using your mobile device. (or scan it if you have a scanner)
Let you phone be exactly above it, not at an angle.
Once the signature fits your screen nicely and looks great, snap the photo.

STEP 3

Send a full resolution photo of your signature to your email.
Go into your email box and download the file.
Open it with Photoshop.

STEP 4: Making a brush

First we need to clean up the white on the paper.
Press Ctrl L or Command L on Mac. This will show you Levels.

Levels dialog with the default 0, 1.00 and 255 input values

Drag the little white triangle on the right-hand side. This is going to clean up the white on the paper.
Do it until all the detail is gone from the paper.

You may need to darken the signature a bit.
Grab the black triangle on the left-hand side and pull that.

Use the slider in the middle to remove the yellow stuff that may be present.

When everything looks good, click OK.

STEP 5

Use Lasso Tool to make a selection around the signature. Close-up of the Lasso tool icon

We’re now going to create the Preset.
Go to Edit>Define Brush Preset.

We can set the name for our brush, and also we are able to see the size of the brush in pixels.

If you want to change the size of the brush, you can go to Image>Size and set the size you need. I chose to keep the full size 2589 px.

When your Brush is all set up, click OK.

Let’s use this photograph which I snapped from my drone.

Get the Brush. Hit the B or grab it from the toolbar .Close-up of the Brush tool icon
