How can you change the embedded date data on photos?

by on March 18, 2012

Q: i need some expert advice on exif data. i realize that there are now programs available to alter the data embedded on photo image files. however, i also realize that when you download an image file to a pc or when you make copies of that image file, you can access the “properties” and view the actual date an image was captured. what i need help with is to know if you do not use a program to alter this original date, will the date remain there no matter what? in other words, are these new programs the only way it is possible to change this embedded data placed there by a camera when a photo is taken?
