In the end for sure I think people could share some info, profiles, or tips but it might become just like commercial software with a myriad of looks, categorized as “landscape” and then you have 15 choices…you might land on one. I often find that those rarely offer a complete solution and for me they actually can be confusing. Often some part of the image is nicely modified and others are not. One person’s idea of nice green foliage can be neon green to another person so its hard I think to do in a way that is really widely applicable. THe best presets will be the ones you arrive on after many iterations of trial and error. Maybe if you throw out a few sample images into the play raw forum you can gather enough tips and looks to form your standard set of profiles that really work for you?? I’m sure you will get better feedback than this so hang tight…
