I don't select High Gloss paper unless the image is, for example a polished car that has shiny paint. In my opinion, Printing on glossy paper downgrades many great images.
When you look around at Landscapes, Gardens, Buildings, Animals, and so on, colours may be rich and vibrant, but not Gloss. Matt paper is superb for photo's that have a wide dynamic range of contrast and colour and presents you with an artistic style.
Do you have a special photo that needs colour correction and/or enhancing?
Images versus Prints - When you view an image on a back-lit screen, the luminance level is the same for every shot. In comparison a print can be Gloss or a non-reflective finish with varying textures. The photo will be improved by selecting the correct paper.
What is a professional photograph? -
One that is high end magazine quality, or one people are prepared to buy.
