Thanks to all those who have posted on the creek regarding granite and marble.
After alot of reading and alot of practice. I believe I have the results ive been looking for.
I gotta give thanks to the Gold Method.
Also I want to add that I found that working with the contrast levels and
burn and dodge tools on photoshop can help increase image quality big time.
One thing about granite to remember is that it turns white very easily.
So high speed and low power worked best for me. 100speed, 50 power on a 25w laser.
What your essentially trying to do is find the appropriate level of power to singe the granite and get light shades of the grayscale. Because too much power will just turn everything white washed.
TIP - I went on the internet and found a grayscale chart! - Then just set your speed at 100 and practice and slowly bring your power level down until you get most or all of the shades of gray. Then you know settings for images! YAY!)

GARBAGE IN AND GARBAGE OUT! High res images work best.
