You can save it a stretch it to the max it can. Do it to the point before it happens, that will be the max point for that pic. Can someone enlarge this picture w/o distorting it?
Depends on how much you want to enlarge it. Usually you can only increase it by about 50% before the distorting becomes noticable.





Unfortunately when you enlarge a picture, it increases the number of ';dots'; in the pictures heights and width. The only way a computer can fill in those extra dots is to estimate from the colors above, below, left and right of the the dot. Every time it does that, it ';blurs'; the picture slightly. There is no way to avoid that using only a computer.





It might be able to enlarge the picture if you were to photograph it, and have the photograph enlarged. Or to use a scanner to scan in a larger version of the picture.



First enlarge it to it's double size with Image/Image Size. Make sure the Resample image option is selected and it is set to Bicubic.





As a second step to clear the jagged pixels around the edges apply Filter/Noise/Despeckle. This makes the image softer.





Now enlarge the image to it's double again and apply Filter/Stylize/Diffuse with the Anisotropic option. This will smoothen the edges further and it enhances the edges of the image. The reason we have to enlarge the image before applying this filter is that this filter is extremely evident at 100% and would destroy the reality of the image. At this size you can see that this filter works as if a human would go over the image with a brush and repaint it, improving the edges and getting rid of inconsistencies.





Next reduce the image back by 50% and apply Filter/Sharpen/Unsharp mask with the options Amount 60%, Radius 2 px, Threshold 2 levels. You can experiment with these options depending on your image.





You are done .....Cheers !!!!
