Hi everybody! I'vbe been curious about what has been mentionned in this topic as i often need to enlarge my picture, I use Shortcut photozoom, wich as you know, add pixels with an advance arithmetic feature. The result is pretty uch good, but, for sure there is noise added, wich desperate me. So yesterday night, I did this experiment as explained here..and my question is I am stupid or am I having an illusion but I found an interesting thing, that seems to me too simple to be true... I took a 72 dpi 300X400 image on the web with achitecturals details...I open it in psp, duplicate it into a vector layer, than rezize the image to 8X10 inches to 300 dpi...Create a new selection and copy it as a new normal rast...I than I save this as a tiff image...I opened it...and is it a miracle or what..the new bitmap image is having really 8X10,between 3000 and 4000 pixels and 300 dpi..from 100 ko I had 40 megs..the image was very crisp and clear..no noise...I check with few editors and averything was the same... Does it means that I really would have the same quanlity i saw on the screen than to print? How could be explained all this trouble to add pixels if converting into vector and back to bitmap is so easy to enlarge..Do i misse something? Thank's a lot for your comments!
