Much ado about nothing.
What determines resolution is based on megapixels (image size).
Your camera has 10 megapixels which makes an image that is about 3648 x 2736 pixels.
That is plenty for printed pictures.
If you have the camera set for smaller pictures, you should change it to the 10 megapixel setting.
Some people (including some printing firms) look at the resolution reading from the pictures EXIF data.
That EXIF resolution data is totally bogus. It means nothing. Any camera maker can set resoluton to any value they want.
Again .... it means nothing.
Here is a link to a full explanation:
I should really take a class to learn how to use my camera more effectively, but I have a question about resolution that I'm hoping someone can help me with.
Lately, every time I try to print my photos to Shutterfly, Snapfish, etc. I'm getting a warning that my resolution is too low on my pictures. I've uploaded them straight from iphoto without retouching them. Do I need to change the resolution on my camera? Can you do that? I read through the manual and didn't see anything about this.
Any advice would be greatly appreciated! Thanks - Jenny
