I want to tell you how we engrave photos on a laser machine. After various tests, trial and error, born algorithm that allows you to get good quality engraving.

Step 1: Excellent Quality Photo

Use photo only excellent quality.
Open in Adobe Photoshop.

<p>Every now and then great results are obtained against all odds. This laser<br>processed picture was scanned at 1200 dpi from a wallet sized faded photo, cropped, blown-up 15X and processed on cheap Big Box Store plywood. It has been my<br>experience that none of those variables are recommended procedures. This is proof that accidents do<br>happen. </p>
<p>I do a lot of engraving on acrylic on a Trotec Speedy 300,and I use a different method. I don't even bother taking out the backgrounds(personal choice). My first step it to convert to grayscale,then I go 300 for the resolution,then I go to adjustments&gt;brightness/contrast and usually make both of those 25,but this can change depending on the picture.</p><p>Next I go filter&gt;sharpen&gt;unsharp mask. I usually go amount-500%, radius-3,and keep threshold at 0.</p><p>I don't even convert to bitmap,I just save it as one. The laser settings are definitely going to depend on your laser,and from what I understand,that goes for each individual laser even if they are the exact same model.</p><p>I'll have to get some wood and try out your settings. Thanks.</p>
Really Cool!!!
