Anna: We discovered that our daughter's new Nikon D80 takes a different memory card than the D70. Instead, it takes the same type of card my Canon S3 uses. We had a card for her, but it was only 1G, so today we went looking for a larger memory card. We ended up getting a 4G card for her, and an 8G card for my S3, since I also use it to record videos.
This photo of a piece of watermelon was my test shot using the new memory card. Not a very good photo to start with, but after using the auto fix function on PSP X2, then using the one step digital noise removal, I liked it a lot better.
We also discovered that our computer's built in card reader doesn't "see" the high memory cards. We have to use the USB to upload the pictures from the camera, rather than directly off the card. That's going to eat up my batteries a bit faster. Ah, well.
