I got a new Panasonic Lumix FX28. It looks great and makes great pictures. But, when I review those big pictures in my computer screen, 1024x768 resolution, and the picture gets reduced to 1:4 for example in order to fit into the screen, the sharpness gets lost and the picture looks misfocused. If I downsize the picture from 2 MB to something fitting full into my screen, the result is the same: picture blurred! I'm sure mine is quite an usual problem. People don't usually have huge screen to look at their pictures, and they like to see them fullsize. How can I convert big pictures to smaller ones without losing quality and sharpness? Would be very gratefull for any help and software tip.
Thank you

A slight softness is normal after resizing. Look for sharpen functions in your software which can restore the appearance of sharpness.

A cheap solution is to use a free program like GIMP which can automatically apply a "sharpen" as part of a resize.

UPDATE: Whoops, I wrote GIMP and I meant IrfanView. :oops:

Indeed, using a different program will do the trick. Maybe the program you are using supports different algorithms to downsize the picture.
Bicubic is better than Linear or Nearest Neighbour, but also slower. Lanczos and Mitchell are only found in very specific applications.

Irfanview is the default image viewing application I use (alongside Lightroom 2). It's free, and does a pretty good job scaling the pictures.

How about resizing the photograph and then sharpening.

That's pretty much what those programs do ;)
