Hi, I developed a device link profile to convert from ProPhoto RGB to sRGB perceptually. I opted for a device link profile because ProPhoto has colors with CIELAB a and b coordinates that exceeds the range supported by ICC PCS. This profile was built using a new perceptual color space I developed in my thesis and can be downloaded freely at http://goo.gl/HI82P8 <http://goo.gl/HI82P8>. Any comments or feedback are welcome! Thank you, Lorenzo
