Hi, My name is Adrienne and I was given a Canon Rebel XSI with two lense for Christmas from my husband. I do not know a THING about photography other than I have played around in Picasa...Anyway to cut to the chase. I had my resolution or selection set on Maximum. I understand that this is 12.2 megapixels and 72 dpi from what I have read. Well, I took some awesome shots on the camera. I went into Picasa to edit them..and when I took them to Walmart to print them out, they were a total blur, I was so upset. Anyway I am a smart, serious person, I am just ignorant to photography. My question is do I need to lower the image quality selection to the "RAW" option, and then I can edit it as a digital negative, and then adjust my DPI in photoshop, I purchased that also. My pictures looked better on my two hundred dollar sony cybershot I have been using, so I KNOW I am doing somthing wrong. I know photography is in the eye of the beholder, I know that. But I can't stand a fuzzy picture, and I just don't think it's the camera! Please any advice on what to do I would greatly appreciate. Also, what DPI does a pic need to be, to print out and it look professional? Thanks!
