I have a Minolta A200 digital camera . I use a San Disk Ultra 11 512 MB Compant Flash card.
As far as I know, although I have not tried it, iPhoto and Preview do not support digital camera Raw file formats. However you should, with a card reader, be able to simply drag the .MRW raw files onto your desktop and place them in a new folder, which you can then burn to a CD.
Your Minoolta A200 camera if purchased new should include an installation CD with Minolta Master application, which you should install on your computer. This Minolta application will open .MRW files and allow some editing and printing.
If you do not have the Minolta CD, I would suggest going to the Konica-Minolta web site and then access Support and download the software that supports using the Minolta Raw files.
I would also suggest, to get the full advantage of raw a more capable application, particularly Adobe Photoshop Elements 3.0 would be a worthwhile investment. It supports opening and editing digital camera raw files, and includes easy to use image editing toobtain the best image quality potential from raw files for a variety of output purposes.
I work on a MAC and I agree. I used to use iPhoto, but using a card reader the it will show up on the desktop as an unlabled folder. When that appears you can open it and drag the images to the desk top. iphoto is of no real use if you have photoshop. Since Elements 3.0 is practical cost wise I think you are right that would be the way to go. Monte Johnson.
