For photographers that give their clients digital copies (as compared to having them purchase prints), I was curious what resolution folks give to their clients. What are the pixel dimensions (i.e. longest and shortest edge) and pixels per inch. I am running out of hard drive space and want to delete the RAWs after I have provided the clients with jpg copies. And I want to retain the jpg copies forever, just in case something goes wrong with the clients' copies. I currently give my clients images that are 3000x2000 pixels with a 500ppi. Others?? thanks much!
