Hi Jinky, I always go for glossy. This is because I have found it aids sharpness. However, for my next printing job I am going to try some metallic prints. I understand that this is the way to go for really great, long lasting prints.
One of the problems with b/w prints I needed to sort out was magenta casting. I spoke via email with One Vision Imaging and they told me that they use an optical process and not an ink process, so there is no colour casting whatsoever. In fact, prints look very close to silver halide prints on the wall.
No, I haven't done any albums with them.
I always put images for printing on disc and send it to them. They give you all the info you will need to format and forward images.
This is one of the five images that One Vision did for me and it was a superb job.
