Hi Nikki,
You can try turning on the slider “Shade According to Power” and that, combined with image adjustments and proper min/max power settings, should help.
Note that the shade according to power option only works with Grayscale with Image Mode or Power Scaling with Fill Mode. If you zoom in, while viewing the Preview, more detail is shown.
I’d also recommend giving our documentation about photo etching a read: Docs Here
