Re: "Painted" Look
HIRALOAM actually accentuates the differences in adjacent pixels by darkening the the darker pixel adjacent to a lighter -which will be lightened. This is all contingent on the tolerance level you set. The difference between the pixels must be separated by a tolerance level based on the 256 levels of gray. Each channel (RGB 0r CMYK) is assessed individually. A high Radius simply means that the effect will continue beyond the adjacent pixels, perhaps as far as 3-4 pixels. Again, relative to your overall image size. Sometimes if my image will allow a CMYK conversion (without a color gamut loss), I have an extra channel to differentiate the details within. I oftentimes add a higher radius to the Black and Cyan channel - where most of my image detail may exist. You can do that separate of your Magenta and I almost never do anything within Yellow as this simply tends to add noise and fringing. Attached is a similar effect that was popular with my client for a while. Same HDR, but a sort of ghousting of the color.
