Hi - I'm think I'm missing some basic knowledge about digital photography and would appreciate some help! I'm uploading photos into iPhoto and then transfering them to Smugmug. Some of my photos fill the screen in iPhoto - the ones with larger file size e.g. 235 KB are perfect. But the photo with with smaller file such as 75 KB appear smaller on the screen, and then likewise appear small in the same ratio when I upload them to Smugmug. I can use the zoom function in iPhoto to fill the screen and they look fine. Is there a way to make them stay that size? What would be nice is to make them all appear to fill the screen without having to individually adjust each one, if that is possible. I'm not trying to crop anything -- I want to keep the content of the entire photo but just make it appear larger for viewing. What am I missing (besides some brains)? Should I be using a different program? Or is there a setting on my camera (Canon SD890) that could be changed? Thanks for any insights!
