100% Zoom not 1:1 actual view?

[tzalmaves]

Hello All,
 
    I'm confused about the "zooming" measurement.  A 3504x2336 RAW on my 1650x1050 screen is "93% zoom" when fit to screen, and that's obviously not correct.  When I go to 100% zoom, I'm not seeing a 1:1 representation of my RAW file.  How do I view a 1:1 representation of my RAW image?

You're seeing a 100% view of your RAW file's embedded JPEG preview.  If the embedded preview is not 100% the size of your camera's sensor then you won't see an image that matches the size of your camera's sensor.

What camera do you have?
What OS are you running?
What version of Photo Mechanic are you running?

Ah, OK.  Is there a way to have the camera render a larger preview?

I know for certain that the 20D inserts a half-resolution preview which cannot be made larger.  I don't know about the 30D and the 5D.

No, I don't think the camera's rendering of JPEG previews for RAW files can be enlarged.  My Canon cameras (1DMkII and 10D) embed half size previews in the RAW files, your cameras probably do the same.  But I convert the RAWs to DNG using Lightroom (wish I could use PM to convert my RAW files to DNG).  When converting to DNG you have the choice to have a full size JPEG preview embedded.  This works great and PM then displays the 100% full size JPEG preview.  You can also use Adobe's free DNG converter if you don't use Lightroom.
