Older and lower quality images in particular will generally benefit by lowering the render factor. Higher render factors are often better for higher quality images, but the colors may get slightly washed out. \n",

We want to help promote this as a standard, especially as the technology continues to improve and the distinction between real and fake becomes harder to discern.
