Ok, so I took a snap of my MAC desktop. The image is automatically converted to a PNG file. I open this file in photoshop, looks great (resolution and all). I try to resize to a smaller size and I loose clarity and resolution and yes, I am trying to scale down, not up. I have tried a few things, flattening image as .eps - adding a vector mask. Nothing has worked. It is probably obvious, but what am I doing or not doing here? How can you take a desktop image PNG file and scale it down without altering/sacrificing the quality/clarity etc.? thanks!
