Nice photos to start. Those presets we're designed with the GRD4 as the main model as are all. You have the FEEL in your shots that are Ricoh User Defined.
Thanks for the support and the fine inspiration for the GRD4. I'm kinda missing using mine....
i've never tried to add "grain"/"digital noise" or whatever you want call it and i have to say i really like the textures that comes out, with both ricoh that i own (grd1 and grd4).
i'm really impressed about what a grd1 still can do
