Newbie question CR2 Files
A friend took some photos for me and gave me the digital data with 2
files for each image-- typically a JPG file 2.96 MB, and its larger CR2 file of 10.5 MB. When I look at the image info on these 2 files in IrfanView here is the data I see: JPEG 300 x 300 DPI 3504 x 2336 (8.9 Mpixels) 11.7 x 7.8" print size 16.7 million colors (24 bits/pixel) #colors 72,643 disk size 2.96 MB mem size 23.4 MB CR2 File 0 x 0 DPI (but after I insert 300x300, it gives the print size below) 1536 x 1024 (1.57 Mpixels) 5.1" x 3.4" print size 16.7 million colors (24 bits/pixel) 48,748 #colors disk size 10.5 MB mem size 4.5 MB My question: Why does the CR2 file (which is a much larger disk file) have a smaller print size than the JPG at the same DPI? I've seen that IrfanView also has a plug-in (which I don't have yet) or some extra DLL's for viewing CR2 files. Could this account for the difference? If I download and install these, should I see a larger print size for the CR2? Thanks for any info. RGB |

Why does the CR2 file (which is a much larger disk file)
have a smaller print size than the JPG at the same DPI? CR2 is the RAW file format for Canon 20D and 1D Mark II dSLR's, you need to convert them from RAW format to tiff or jpeg before it's meaningful. |
