Problem with "Save photo as" command

[bluezzzzz]

I am running Photo Mechanic version 4.6.6 and I run Mac OS X 10.4.11 on my Intel-based Mac.

I'm having trouble with the "Save photo as" command when trying to save from a DNG.

If the "no scaling" box is checked in the image processing window a JPEG High Quality is rendered as a 1024 x 683, 404 KB file of low quality.  Similar results when asking for a TIFF file.

Checking the custom width box and adding the 5616 x 3744 pixel dimensions of the DNG gets a 6.8 MB JPEG file of poor quality, or a 6k0 MB TIFF file, also of very poor quality.

What am I missing or doing wrong?

Thanks,

What camera did the DNG file come from?

If you use the 'Extract JPEG Previews from RAW photos...' command on the Tools menu, do you get a low-resolution image?  If so, reconvert your DNG and have the DNG converter put in a higher quality JPEG preview.  If the source JPEG Preview is low resolution/quality, so will be the output of any Save as operation from the DNG file.

Kirk,

Bingo!  Thanks so much for the help.  That was driving me nuts!
