When I open 27 MB RAW files, Photoshop brings them in at 139MB.  Is there a way to have them open up smaller?

Yeah... look at bottom center of Camera Raw... theres an underlined link with the size. Click that link and set you open size.

Thanks. That's a work around that will work, but not what I meant.  I would like to tell the system to limit the file size to say 25 MB automatically.

That would mean that you will have to downsize the image. A raw file contains only one color per pixel. When the image is opened in Photoshop it is ‘demosaiced’ and becomes an RGB file with three colors per pixel. That means that it is completely normal and to be expected that your image in Photoshop is three times as large (could even be more if the raw file is compressed). If you set Photoshop to open the raw file in 16 bits per color, this doubles again.

That's the size of the image if you were to save it as an uncompressed tiff and it's just an estimate but pretty close.
