Re: [Digital BW] Re: Upsize Report

2006-01-10 by Peter Marshall

I think if you try it you will see both the possibilities and the 
problems, and it well illustrates why I've never believed that this is a 
serious problem. If you really want to rip images off, you will 
generally get much better results from print than from the web.

Of course anyone is welcome to print any of the several thousand images 
I have on various web sites to pin up on their walls etc. The quality 
they will get - even with the best software - will not be any kind of 
competition to the prints that I'm making from the 20-50Mb or so files I 
typically print from. I actually feel gratified that some people find 
the pictures interesting enough that they want to possess them even in 
such a limited way. Even better was coming across one on a T-Shirt!

Regards

Peter Marshall
