A. 1. Zoom in on the area you are refining to gain better control over the adjustments. 2. Use a stylus for more precise editing if you find it difficult to use your fingers. 3. Adjust the brush size in the refinement tools to allow for more detailed work.

B. 4. If the tools are still not precise enough, consider using another app that specializes in detailed editing and then import the image back into Pixelcut for further adjustments. 5. Practice using the tools on less important images to get a feel for their sensitivity and responsiveness.
