this has never happened before. i'm using the autostitch program to make a pano. when i lower the exposure in LR the image becomes pixelated and blocky. any reason why? maybe because the original is a jpg?

Or, if Photostitch has the option, increase the quality of the jpeg it produces to the maximum value. Or both! Frank Hollis - Retired mass spectroscopist

The other option is to export the pano as a tiff file. That will give you more leeway in making LR adjustments. Tony
