An image shooting system capable of generating high-quality and high-definition images is provided through a camera even when a user of the camera has no knowledge on the camera's settings or photo-shooting techniques, or when the performance of the camera itself is low. There is provided an image shooting system having an image shooting apparatus and a server connected to the image shooting apparatus through the Internet, wherein the image shooting apparatus comprises: a unit for recording image shooting condition parameters as meta-information in a file of an image taken; a communication interface for connecting to the image shooting apparatus to the server, sending the image file to the server, receiving from the server and storing, optimal image shooting condition parameters for optimizing an image quality of the image file; and a unit for reading the optimal image shooting condition parameters received from the server and setting them as an image shooting condition for the image shooting apparatus based on user selections, wherein the server comprises: a unit for obtaining a image file from the image shooting apparatus; a unit for reading settings described in meta-information and determining a model of the apparatus; and an optimal image shooting condition parameter calculation unit for analyzing the image quality of the image file based on a predetermined algorithm as well as calculating, based on the determined model, the optimal image shooting condition parameters for the model to take the image.
