Re: Prints

Any decent print lab should be able to handle any file that they get and do their own interpolation to what their printer needs, it's just that you need to consider the original camera pixels per inch of print to determine the quality. At 414 ppi all is good as far as quality is concerned.

The print lab may be interpolating up or down to suit their equipment. That's why you need to talk to someone about what they need. The "dpi" figure that is attached to jpeg files is something that confuses many. That can be ignored for most occasions and only think in terms of the print size and the original camera pixels and what pixels per inch is being used, despite any interpolation that may occur to make say 414 ppi to 300 ppi. Photoshop is famous for insisting on dpi numbers and confusing people. The jpeg dpi number is just a soft instruction to the printer as to how to print the file, whatever size the file is.

great, thanks for the further explaination.
