Digital Home Thoughts: winkflash Offers 'High Definition' 450dpi Photo Prints

"It means at Winkflash you are getting the highest resolution photograph available in the world. Our competitors offer all of their photographs at 300 DPI. This might seem like a lot, but when you look at how many dots there are in every square inch, you notice the difference. With 450 DPI, you get more than twice as many dots. That means your photographs come out with more detail, the colors are more vibrant, and the contrast ratio is better."

The term "high definition" is being slapped on everything lately, but in this case I think winkflash is secure in their bragging rights: offering 50% higher dot density is significant. The question is, will anyone be able to notice on small prints? I imagine on 8 x 10 inch prints you might be able to tell the difference, but on 4 x 6 inch prints? I'm not so sure. Has anyone tried these new prints from winkflash? If so, what's your opinion?
