So I've just spent the better part of 5 hours on here reading past threads about this problem as I too had this happening... The processed JPEG that I opened in Windows Picture & Fax Viewer looked really soft compared to the modified RAW that was still open in DPP 3.5.
I followed what a member on here (Rene Damkot) was saying... compare them at 100% and decide. Rene was right, the images were about the same... a bit better result.
But to tell you the truth I dont really want to spend all this cash and time on photography so that when I show my mates or fiancee what I've been up to, the images look really soft at first glance.
I opened up the JPEG with Windows Viewer, the RAW with DPP and another copy of the JPEG with Quicktime Picture Viewer 7.6.
The Windows viewer was soft
DPP was sharp
Quicktime viewer was sharp
Any ideas why this would happen ?? Why would the programs differ ??
Is there another viewer I should be associating JPEGS with ?? or stay with Quicktime...
