The other day I stood in line with my son to collect some autographs on some photos I had made of our favorite Tampa Bay Lightning players. I had also a plain piece of white paper that I had brought along as a protector and at the last minute I decided to collect on it autographs of players whom I didn't have pictures. When I got home I scanned the paper into Adobe Elements and proceeded to try to extract the signatures. The before and after pictures at the end of this posting shows how well I succeeded.
The autographs were signed with a black fine point Sharpie pen making the black / white contrast as good as possible. Once the page was scanned into Elements I separated each autograph
into their own layer using the Lasso tool expecting to have better control over the extraction than by using the whole page. Each autograph was then treated the same as follows.
- Using Enhance / Adjust Color / Remove Color I created a black and white version of the layer.
- In order to get as much contrast as I could I created a new adjustment layer for each autograph layer with Layer / New Adjustment Layer / Brightness/Contrast and moved the Contrast slider over all the way to the right.
- Both of these moves made removal of the white easy using the Magic Wand Tool. I set the Tolerance to about 25 and removed the Contiguous check mark to delete all of the white even within the pen strokes.
- After each autograph layer was completed I added a team logo that I had gotten from previous scan and a blue and white gradient fill layer with Layer / New Fill Layer / Gradient.
- Since all of the signatures are impossible to read I added extra text layers for the player's names and numbers.
- One or two of the autographs ended up too light in spots because the player used a light pen pressure. I fixed this by using the Pencil Tool with black Foreground color. I had to use a tablet to do this as the mouse didn't give me the control and pen pressure that I needed.
I think the technique worked so well that I won't worry about having to have a picture with me in the future. I'll collect the autograph on a piece of paper and transfer it to the picture in Elements.
