I agree. However, dpi only comes into play when printing, it doesn't have an influence on file size. It determines the physical size of the print based on number of pixels you have per side of your image.wolverine wrote:heinz-oz wrote:To make a photo quality image using RA4 process the image has to be 300dpi at the size you want the final print to be.wolverine wrote:Can you even print that large or do you have it printed by a professional?
You are mixing dpi with ppi. An electronic image does not have a resolution nor does it have a physical size, its only dimensions are the number of pixels and its color depth.
An image of a given size has a file size of xx MB on your HDD. It will print in different sizes with different dpi settings. These dpi settings have no influence on the file size, that will still be xx MB, regardless of the print resolution.
