Adjusting A photo to lazer engrave onto wood

Hi All,

I am hoping that somebody out there is willing to help me out, I have coreldrawx7 which I am using for lazer machine, I have had it for a year now but I am now looking at engraving photos onto wood. The problem I have is that I have watched a few videos on youtube but it just isn't looking right for me to use at all and when I try it don't  look good at all.

Can anybody out there give me some advice on what to do and how to get the best possible picture I can so it looks good. I can crop the photo/turn greyscale etc to start but its getting it right in contrast enhancement etc to change the photo suitable for engraving, I know it can be done as I have seen some excellent quality images on worse than my machine I must just be missing something somewhere.

Any help from anybody would be great.

thank you so much

Dave
