Expanding Photos Without Losing Resolution ?

[MegalosSkylaki]

Now that I have a 22" monitor in Portrait Mode, how can I expand Photos and Pics without losing reolution?

Do I need a Vector Graphics program?

What is the simplest/cheapest program(s) for expanding graphics?

What do you mean by losing resolution? Do you mean the picture being pixelated? Because when you expand a picture you actually gain resolution.. Well as far as I know, there is no way to have your pictures expanded and not look blury, because you simply do not have enough data to make a nice sharp and big picture.

With that said, some programs are better at making your pictures look good than others. Have a look at GIMP for starters.

Yes I do mean without getting blurry.

There must be some graphics SW that "fills in" the pixels according to an algorithm to offset the otherwise loss of distance or larger size of pixels.

Are we looking at a $600 + proggie?

ThanX.

For image viewing and editing, you simply need an app supporting bicubic, Lanczos, or similar interpolated resizing. Still, don't expect miracles.

Bicubic interpolation - Wikipedia, the free encyclopedia
Lanczos resampling - Wikipedia, the free encyclopedia

Anyway, you are in luck. Many free and open source graphics apps support such scaling methods. I generally recommend Paint.NET for basic work and GIMP for more advanced work.

Paint.NET - Free Software for Digital Photo Editing
GIMP - The GNU Image Manipulation Program

I've used Irfanview for years with good results... it offers Lanczos
resampling as well.

I'll check them all.
