Increasing low reselution picture size (Jpg)

by blockisle9 / June 4, 2004 11:42 PM PDT

I hope im posting in the right area. I have some very small pictures that are of very low quality that I wish to increase the size. (When I try to increase the size now the picture quality is so bad it?s not usable.
Is there a software product that can do this?
I have tried to do this with Photo Express (Increased the pixels and the size but no good)
Thanks
Lenny
PS- What I was thinking of tiring was to print the small picture, then re-scan this image but at a much higher resolution then try to re-size this picture.
Does this sound like a plan?
Thanks again

You can try the printing trick. It might not look so bad, but in general there is nothing you can do to increase the quality of a low resolution image. There are various schemes; different kinds of interpolation, etc., but the bottom line is that nothing can add in meaningful information that isn't there to begin with.

One of those misconceptions that get propagated by so many movies and television programs is where you see them take some low res picture and zoom in and read the fine detail of something. Like, when they use a traffic "red-light" camera and "zoom" in read the headline of some newspaper some JohnQ is holding.

That is all "sci-fi"
It is normally impossible (I will leave a little of possibility here) to get more data from a picture than what is there to begin with.

Now, if the pictures you have are something common, something that perhaps others may have also taken at one time or another, you MIGHT just find a similar or identical higher resolution picture by using Google Images

Just go to that website and enter in some of the particular search words you think pertinent.

Good luck!

Actually there are several Photoshop plug-ins that are available to do just this.Personally I use GenuineFractals 3.5 tho there are others available.Another method that is often used is to increase the resolution in 10 percent incriments until the photo is the desired size and then apply a moderate amount of sharpining.Remember tho this method won't work miracles ie. Garbage in - Garbage out.
