help with lightroom 3

Ok I have recently upgraded to lightroom 3 from lightroom 2 and I have noticed that after I export my photos for the web I’m getting a very poor image. Looking close they have pixels that are rough or squared around corners of subjects. I have tried to adjust everything in exporting and importing but I have the same issue. Does anyone have any ideas what is going on? I’m sure it is something simple that I am overlooking but if I can’t salve it I’ll go back to my lightroom 2. Thanks…

More info? What are you importing from? Where are you importing to? What file format? What settings are applying during import? What are the pixel dimansions of the imported images? What is your selection for 'Rendered Previews'? Any othe info? - Terry

sounds like you went low res somehow? How are you exporting and where are you sending these?

You need to change your output resolution setting, and then adjust the JPG compression setting to get the image quality you wish. If you using the export function to save your edited images to JPG look for other saving options.
