Why you can’t increase the resolution of an image
One of the core understandings in computer graphics is that if you want a high resolution image, you must start with a high resolution image. Forget all the tv shows that you’ve seen where the person is standing behind a computer technician asking them, “Can you sharpen the image a little more?” The computer technician maybe clicks a few buttons and the suddenly the license plate that was too blurry to read becomes crystal clear. It’s a miracle, the computer can do anything! Sorry, that isn’t real life, at least with current technology.

Artist Interview: Greg Senn
If you’re new to kennethcurtis.com, I’d first like to welcome you to the new design and hope that if you get a chance you’ll take a moment to look around. One of the many goals of this site is to create an area for artists of all kinds. It doesn’t matter if their chosen area is in fine arts or applied arts and even if they fall between the two, all are welcome.
As the function of the webmaster/creator of this site I get the honor and privilege to invite Greg Senn, one of my closest friends and favorite artists to be the first interview. As well as being a certified scuba diver for nearly twenty years, he has been an artist and art professor for about thirty years. Greg has primarily based his work on casting and metal work and it truly remarkable some of the pieces that he has created. His work ranges from serious to playful and he seems to revel in the freedom that art gives him.
