Saving/Blurry

Saving/Blurry
I can get my images to look real nice and sharp in GIMP (2.6.11), and I then save the images (either as JPGs or TIFs), but when I then open up the images to look at with my picture viewer the images are blurry. I don't have that problem with my Irfanview program, and in fact I can import the blurred GIMP images to my Irfanview, sharpen them up and save them, and they then look nice and sharp with my pic viewer.

So my question is, why do my GIMP images get blurry when I save them?

Screen shot one is the image processed in GIMP and ready for exporting, and screenshot two is the image on my viewer after it's been exported.

Although the difference in image sharpness isn't nearly as apparent via these screen shots as it is when viewed on my computer screen, I think you can still see the difference.

RE: Saving/Blurry
Thanks for the Windows viewer "actual size tip", Paynekj, that does sharpen things up a bit.

I view all different sized images from three different processing programs (GIMP, Irfanview, and Rawtherapee) using the Windows viewer on my CRT monitor, Ofnuts, and the only images that appear blurred are the one's saved from GIMP, so something isn't jiving between GIMP and my viewer. I did switch from Cubic to Sinc/Lanczos interpolation, but that made little difference, so perhaps I'm forgetting to tick something in GIMP's option menu when I save GIMP images, but I can't think of what it would be.

RE: Saving/Blurry
I didn't even know that there was an advanced save menu. I changed the subsampling to best quality and now my images are much sharper. Yessssssss....

The more I'm learning how to properly use GIMP the more I'm liking it - the quality of my images after processing seems to be better in GIMP than with Irfanview or Rawtherapee.

Thanks once again for your help Ofnuts.
