I believe frames function differently in a number of ways on the screen than they do on the wall. I am not bothered by your frames Rob. With yours the black is more of a line than a shape and they give you somewhere to write other than on the photo its self.
To be brutally honest with myself, I have always feared real framing for the wall; I've been seduced by brushed aluminium Daler frames that I used to put calendar pulls into during the 70s and I still have/use the same ones now; only the images have been changed. What happens there is that familiarity steps in and makes anything different feel sort of wrong, but that's really just the comfort zone getting pricked... I really do think that only someone with a lot of professional framing experience has the developed eye to see what makes a pic look at its best. Another aspect that freaks me out is deciding on the width of the board...
As it is, my venerable aluminiums all fit a standard A3 sheet quite well, and mounted on a black card that's wider all round, it all looks fairly presentable. Of course, that means the glass is pressing onto the print, but who cares? The glass restores lost tones to the hated matt papers on which I have to print.
The longer I put images onto the web rather on paper, the less inclined I become to print at all; could I but determine the cause of my softened shots here, I'd be almost happy!
