Used just the red channel for luminosity.
tried to extract the diagonal moire. Made a motion blur in the directions of the stripes. Then high pass and gaussian blur. Inverted this layer and blended with the red channel, blending mode soft light.
Blended the resulting layer with a color corrected layer from original data.
USM with edge mask. Median and gaussian blur with inverted edge mask.
Selected red roses and raised the saturation and lowered the lightness for red color.
