Reducing Image Resolution

[motorollin]

If you're using Windows and you can afford it, then I would try Photoshop. I use it all the time to dramatically reduce the size of images. I have created a "90% resize" macro. I then keep clicking it until the picture is the size I want. Reducing it by 90% lots of times seems to lose less quality than reducing it in one hit.

There is also software which plugs in to Photoshop which actually turns your image in to a Fractal algorithm. It can then use this mathematical formula to generate a larger/smaller copy of the image without losing quality. The one that springs to mind is "Genuine Fractals", but their web site focusses on enlarging rather than shrinking pictures. You may want to research this or other apps which do a similar thing.

Well the examples on the Genuine Fractals home page were amazing. The difference between the same resize operation using bicubic resampling compared to Genuine Fractals was like chalk and cheese. Well, it was the same picture, so it was like two very different cheeses :-)

Having said that, there is nothing on there about shrinking the image so I don't know whether this software will help you there.
